Through Hole and Surface Mounted Technology

Through Hole Mounting: This mounting technique involves different components which have lead wires that are led to the board through holes, hence the name. In this method, leadsrely on holes in a multilayer PCB. The leads are then finally soldered to offer permanent mounting. The technology finds usage inDIP aka Dual Inline Packaging and Pin Grid Array Package.

Surface Mounting: This is a relatively new mounting method worked out seeing a tremendous increase in the number of pins in Integrated Circuits. As demand for smaller weight and size of packaged weight increased, there was felt a need for a new, improved technology that came to be known as surface mount technology (SMT). In this leads are soldered on PCB surface directly rather than using hole mounting. The technology is used in Flat pack Packages and Chip Carrier Packages.

There are some points that make SMT different from Through Hole, which has been briefly summarized below:

1. SMT has helped significantly in solving the space problems that were commonly noticed with the Through Hole mounting.
2. The pin count has increased greatly in SMT when compared to its older counterparts.
3. In SMT, the components are leadless and are directly mounted to the board surface. In Through Hole the components have lead wires that are taken to the wiring boards via holes.
4. The Pads on the surface in SMT are not used for connection of layers on the printed wiring boards.
5. The components in the Though Hole Technology are larger which leads to lower component density per unit area. The packing density that can be achieved with SMT is very high as this allows mounting component on both sides, when needed.
6. SMT has made possible applications that seemed impossible with through hole.
7. SMT is suitable for high volume production that gives access to lowered cost of unit assemblies which is not possible with through hole technology.
8. With SMT acquiring higher circuit speed is easier due to the reduced size. SMT fulfils one of the prime marketing requirements while assisting in making high performance circuits in a very small size.
9. SMT has a disadvantage as the capital investment involved in its machinery and production is higher.

10. Designing, production, skill and technology required in implementing SMT is very advanced when compared to through hole technology.When comparing both, SMT surpasses Through Hole in advantages, which clearly define and justify the majority (90%) use of this technology in board assemblies. Through Hole however is anticipated to remain in use in testing and prototype applications that may need manual adjustments and replacements. Its complete disappearance from the scene seems to be ruled out.

When to send a developing mail to your customers

4 layer PCB

(click pic above to see more)

As everyone knows, it is very important to know to how to write a good developing mail to customers. When you surf in the internet and you may find many good examples. But does it mean you are successful when you get one good mail?

Obviously, the answer is “no”. You should know how the customers work in one daytime and then you know when to send a developing mail to your customers. It is the best time to send a mail to clients in their morning time of 9:00 -10:00 when they are receptive to offers on a whole range of the subjects at their starting work in one day. At 10:00 to noon time, customers begin to be focused on their own job. So please don’t disturb them during this time. When it comes to 12:00--2:00 pm., it is lunch break time, and most of them are likely to do some reading on news and magazines while they are not usual to open their market emails. During 2pm--3pm, in the immediate post- lunch period, customers remain focused on work, only responding to emails offer relating to financial services. 3pm--5pm, a life changing afternoon, job related apathy sets in, meaning more emails relating to property and financial services are opened than any other type of promotion. At 5pm to 7pm, working late, there is a dramatic rise in holiday promotions being opened during this period. This is also the timeframe during which recipients are more likely to open b2b promotions. At 7pm to 10pm, the last orders, recipients are more likely to respond to customers promotions in their own time. Offers on clothes and special interests such as sports and gym promotions  perform extremely well during this period.  And finally, during 10pm to 9 am, it is the abyss, and it is an impressive time to send mails to customers. It is just like to throw emails into a black hole.

In conclusion, you should know how to write a good developing email at first. But when to send a developing mail to your customers seems most important.

What are Aluminum PCBs?

Also known as metal base PCBs, aluminum based PCBs comprise metal based laminates that are covered by copper foil circuit layers. They are constructed utilizing alloy plates, which consist of a combination of Aluminum, Magnesium, and Silumin (Al-Mg-Si). These PCBs are known for their beneficial features such as electrical insulation, good thermal potential, and high machining performance.

Aluminum PCBs differ slightly from general PCBs. The structure of this PCB comprises:

Base Layer: This layer consists of an aluminum alloy substrate. The use of aluminum makes this PCB an excellent choice for PTH technology. Holes can be cut, punched, or drilled to the requisite sizes.

Insulation Layer: While the base layer is certainly important, the thermal insulation layer is a critical component of this PCB. It consists of a special ceramic polymer, which has excellent viscoelastic properties and thermal resistance. The insulation layer also protects the PCB from thermal and mechanical stresses.

Circuit Layer: This layer comprises the copper foil mentioned earlier. Generally, PCB manufacturers utilize thick copper foils, which can range from 1oz to 10oz.

There are certain materials and processes that can be used to augment the performance of the PCB. These include gold plated HAL, lead free RoHS assembly processes, immersion gold silkscreen, and OSP anti-oxidation processes.

While aluminum PCBs consist of the same width and thickness as FR4 PCBs, the alloy plate allows the PCB to increase its conductivity to 2.0. Also, it can carry higher currents and withstand up to 4,500 volts of electricity.

If you need expert PCB assembly service, feel free to contact WONDERFUL PCB. 

Layers

The cheapest PCBs are single sided boards. This means that they are just made of the base material, with a single sheet of metal over the top.
Single sided boards are incredibly easy to work with, if you are making your own PCB at home you will most likely be designing for a single sided board.
While the single sided boards are simple to manufacture and understand, they can also be a pain when laying out your PCB. Since you only have one layer of metal to work with, you cannot cross electrical connections without the help of some external jumper.
As a result of this complication the majority of simple commercial and hobbyist boards are created on double sided PCBs. On a double sided PCB it is a simple matter to cross electrical connections and this fact allows for more complex yet elegant design.
For all but the simplest of designs I recommend designing for a double sided PCB. This is generally the most cost effective method that will leave you with the least headache possible.
As designs become even more complex, it may even become necessary to add additional layers to your design. This can be useful if your board has incredibly complex signal paths or if you are aiming for a compact design.
For the majority of users I do not recommend using more than two layers, if you do this and do not need to you will end up with an unnecessarily complex design that will cost more to produce.

Repairing printed circuit boards - tips by Exception PCB

PCBs, or printed circuit boards, have revolutionised the electronic industry; however they lack the robustness of the earlier, steel-chassis, hardwired equipment, driving them to be much easier to crack. Restoring a circuit board needs a particular level of analytical ability, along with the skill to handle each element in the correct way.

Without having a thorough knowledge of the way a circuit board works, experts from Exception PCB express that diagnosing the trouble will be a problem. For PCBs that are especially complex, you might also need an oscilloscope to discover signals at different points, so as to discover the section which is creating the problem. Once this component has been discovered, it will then have to be replaced. Here, Exception PCB provides you with a brief guide on how to do this.

As outlined by Exception PCB, with the majority of passive (and occasionally active) components, a similar, as opposed to an exact copy of the broken element can be used as a replacement. You will find, for example, several unique versions of voltage regulators available, and one version can easily be swapped for another in a PCB. However, broken active components that have a very specific function (for example, audio amplifier chips) must be replaced with an exact copy.

After you have acquired the right replacement, you'll have to place the PCB on a flat surface for the fix. Exception PCB says that you might use tape to stick the board on both sides to the surface, to ensure that it doesn't move whilst you are carrying out the replacement. Pull the damaged component off the board very delicately, using tweezers. Next, switch on your soldering iron and set it to about 400 degrees Celsius.

Take some copper wire and put it on the pads of the PCB where the component was, and use the soldering iron to heat it. Wonderful pcb that any surplus solder remaining on these pads could be absorbed by the copper. Get in line the leads of the replacement component with the board's pads, taking a look at to make sure that the element is aligned as it needs to be. Then, use the soldering iron and the solder to join the leads with the corresponding pads on the board.

Multilayer PCB design method (Z)

11.4.2 The electrical layer segmentation method
(3) Click in figure 11 - 15 electricity layer segmentation OK button in the dialog box, enter into the state of network area box drawing. Electric layer frame in the drawing, the user generally will be other levels of information hiding, only show the current editor in electric layer, convenient for frame drawing. Select the [Tools] / [Preference..] command, pop-up dialog box shown in figure 11-16. Select the Display options, and then choose the Single layer mode check box, as shown in figure 11-16. So, in addition to the current working layer power, the remaining layers are hidden, display as shown in figure 11-17.


Electric layer within the division, because the integral area will all the network's pin and welding plate are included, so users often need to know the pins with the same name with the power supply network and the distribution of welding plate, for segmentation. On the left side of the tool, select the VCC network browse PCB (as shown in figure 11 to 18), click the select button will light up the network selection.

As shown in figure 11-19 for the VCC network lit after selection, network Numbers as VCC welding plate and pin with other network label welding plate and pin.  Select the network after the welding of the same name, when drawing the boundary can be these pads are eating into the division of the region. At this time the power network can not through signal layer of attachment but directly through the welding plate is connected to the electrode layer.

1. Sandblasting, main effect is the surface cleaning, sand blast before coating (paint or coating) can increase the surface roughness, has certain contribution to improve adhesion, but the contribution is limited, as chemical processing before painting.

2. Color: there are two main types of coloring of aluminum process: one is aluminum oxidation coloring process, the other one is aluminum paint electrophoresis process. In the oxide film is formed on a variety of color, to meet certain requirements, such as optical instrument parts are commonly used in black, commemorative medallion is made with gold, etc.

3. Conductive oxide (chromate conversion coating) - for both protection and conductive occasions.

4. Chemical oxidation, with thin oxide film, thickness of about 0.5 ~ 4 microns, and porous, soft, has good adsorption, can be used as the bottom layer of organic coating, but its wear resistance and corrosion resistance than the anode oxidation membrane;

Aluminum pcb and aluminum alloy chemical oxidation process according to its nature of the solution can be divided into two types: alkaline oxidation and acid oxidation.
According to the layer properties can be divided into: oxide film, phosphate film, chromate film, chromic acid, phosphate film.

5. Electrochemical oxidation, chemical oxidation of aluminum and aluminum alloy processing equipment is simple, convenient operation, high efficiency, no electricity, the applicable scope is wide, without being limited by the size and shape of the parts. Oxide film thickness of about 5 ~ 20 microns (hard anodic oxidation film thickness up to 60 ~ 200 microns), has high hardness, good heat resistance and insulation, corrosion resistant ability higher than that of chemical oxidation film, porous, has good adsorption capacity.

6. Spraying: used for equipment of external protection, decoration, usually on the basis of the oxidation. Aluminum should carry on the pretreatment before coating to coating and artifacts in combination with strong, generally there are three measures.
1. Phosphate method (phosphate) 2.Chromium (without chrome) 3.Chemical oxidation.

Some points should be noticed for etching

Reduce erosion and protrusion along the side to improve the etching factor. Produce sudden lateral erosion along. Printed in the etching solution is usually longer, (or use the old vacillating etching) the more serious side etch. Lateral erosion seriously affect the accuracy of printed conductors, would severely undercut the production of fine wires become impossible. When the lateral erosion and sudden decreases along the etching coefficient is increased, a high etching coefficient indicates the ability to maintain the thin wire, so close to the wire after etching artwork size. Plating etching resist either tin - lead alloy, tin, tin - nickel alloy or nickel, can cause sudden excessive wire along a short circuit. Because projecting along easily broken down, between two points of an electrical wire bridge.

Board and the Multilayer pcb board to improve the consistency between the etch rate. Board in a continuous etching, the etching rate is more consistent, more uniform etching of the board can be obtained. To meet this requirement, must ensure that the etching solution in the whole process of etching remain etched in the best condition. This requires selection easy to regenerate and compensation, the etching rate of the etching solution is easy to control. Used to provide constant operating conditions and parameters of the various solutions can be automatically controlled processes and equipment. By controlling the amount of dissolved copper, PH value of the solution concentration, temperature, solution flow rate uniformity (spray nozzle and a nozzle system or swing) or the like.

   Improve the safe handling and etching thin copper foil and the ability of the etching thin laminate multilayer thin laminate inner layer so when the board is easy to wound on rollers and transfer wheel and cause waste. Therefore, the etching of the inner plate device must guarantee smooth, reliably handle a thin laminate. Many equipment manufacturers in the etching machine gears or rollers attached to prevent the occurrence of such phenomena. A better approach is to use an additional Teflon coated vacillating envelope sent as a thin plate supports. For thin foil (e.g., 1/2 or 1/4 ounce) etching, must guarantee not to be scratched or scratched. Stand like a thin copper foil etching 1 ounce copper on the mechanical drawbacks, sometimes more intense vibrations are likely to scratch the foil.

Why use surface mount technology (SMT)?

Currently, advanced electronic products, especially in the computer and communications electronics products, has been widely used in SMT technology. SMD devices on year rise in international production, but production is declining conventional device, so as time goes into between, SMT technology will become increasingly popular.
So what is the advantage of SMT?
1,The pursuit of the miniaturization of electronic products, perforated and plug components used previously been unable to narrow.

2, The electronic product features become more complete, integrated circuit (IC) is no longer used by the piercing element, especially in large-scale, highly integrated IC, had to use surface mount components.

3, Bulk products, production automation, factory should take a low-cost high-volume, producing high quality products to meet customer demand and enhance market competitiveness

4, The development of electronic components, integrated circuits (IC) development, multi-application of semiconductor materials

5, Electronic technology revolution is imperative, chasing the international trend

SMT has become a mainstream technology in the era of high-density, due to the use of SMT technology,Aluminum pcb, PCBA  also follow up and get rapid development. SMT market share surge makes more stringent, good PCBA SMT is a prerequisite for success. SMT mainly from the process to control the quality of the process. Today we will introduce single Sided SMT assembly process.

Single Sided SMT assembly process：

Incoming inspection -> screen printing solder paste (dot patch glue) -> patch -> drying (curing) -> reflow soldering -> Cleaning -> Test -> Rework

Worldwide Semiconductor Sales Expected to Reach $358 Billion in 2015

Worldwide semiconductor revenue is forecast to reach $358 billion in 2015, a 5.4 percent increase from 2014, but down from the previous quarter's forecast of 5.8 percent growth, according to Gartner, Inc. The market is being driven by strong growth in application-specific standard products (ASSPs) in smartphones, along with DRAM and NAND flash in ultramobiles and solid-state drives (SSDs).

"Semiconductor revenue growth in 2015 is expected to slow from the 7.9 percent growth experienced in 2014 as DRAM returns to more traditional price reductions and the industry burns off excess holiday inventory," said Jon Erensen, research director of Gartner. "DRAM pricing was unusually firm in 2014 due to short supply, which propelled DRAM to be the fastest-growing device type in 2014 with 31.7 percent revenue growth. DRAM supply and demand will be in line in 2015, driving bit pricing down a more traditional 16.8 percent and reducing annual DRAM revenue growth to 7.7 percent."

From an application point of view, smartphones, SSDs and ultramobiles will see the largest dollar increases. In 2015, compute applications will continue to be the largest market for semiconductors, followed by wireless and consumer applications. Combined, these three device categories represent more than two-thirds of total semiconductor revenue and have the most influence on the overall strength of the semiconductor market.

However, in 2015, the industrial electronics segment is expected to outperform overall semiconductor market growth and other electronic application categories with revenue growth of 9.1 percent. The growth will be driven mainly by LED lighting applications for industrial and residential purposes and smart city projects. In addition, the PCB manufacturing will continue to drive very strong unit growth in 2015 and beyond.

Following industrial applications, wireless applications — driven mainly by mobile phones — will be the next biggest growth market for semiconductors in 2015. However, the 2015 revenue growth forecast for wireless applications, and specifically mobile phones, remains the same as the previous quarter's forecast.

"While mobile phone semiconductor sales will remain robust, driven by the accelerating shift to smartphones and 4G Long Term Evolution, there is concern that weak sell-through for other electronic equipment categories will result in higher inventory levels and drag down semiconductor sales in the first quarter of 2015," said Mr. Erensen.

PCB Prototype Assembly Services

The evolution of our world's technology is truly astounding. In the past decades, we've made great leaps and bounds in terms of what our electronic devices are capable of accomplishing, and things are only getting better. Technological engineers and electronics designers are continuously dreaming up new ways to improve existing products, as well as completely original ideas for simplifying everyday life and tasks. But how does this process occur, exactly?

Every bit of technology - from the smallest, consumer electronic gadget to complex healthcare and aerospace units - begins with an idea. From here, plans can be made to develop a working prototype in order to test the capabilities of the device and to determine whether the idea is worth investing in, or how it can be further expounded upon in order to make it more operable, functional, and efficient. Every step in designing and assembling the prototype is essential to enabling the simple dream to become a reality. To give you a better idea of the process, this post will walk you through the life cycle of a prototype.

The Idea Phase
At this point, you or one of your clients may have a thought for how to improve an existing unit or device, or for creating something brand new. Here, you discuss what the PC board should be able to accomplish, what the functions of the device should be, and the sizing requirements for the unit and, therefore, for the board.

The Design Phase
Once you have a good idea but any size constraints for the board and know what it is that you want to be able to do with it, you can begin actually planning and designing the schematics for the PCB development for the prototype. You'll need to consider the necessary components for achieving your objectives, and how these will factor into the layering and thickness of the board, as well as any budgetary concerns.

The Assembly Phase
After the design schematics have been tested out and approved, the board is ready to be assembled for the working prototype. In order to ensure that the PCBA manufacturer will be functional, efficient, and effective, it's important that all settings are properly calibrated (for automated processing), and that the use of the most advanced equipment is utilized so that every component is laid out and connected with the utmost precision, while still maintaining speed.

The Testing Phase
After the board has been assembled, it will need to be subjected to testing. First, you or your contract manufacturer will need to analyze the PCB to ensure that it's actually functioning in accordance with the client's specifications and the design schematics that were previously drawn up. Any inconsistencies or errors will need to be troubleshooted and addressed before the board is presented to the client. From here, the client may want to run their own set of tests, and actually test out the use and functionality of the device as a working whole before making a decision about ordering a larger batch.

The Adjustment Phase
After testing out the initial prototype, you or your client may notice certain areas that could be improved upon, which would make the end product more efficient and effective. After making not of these areas, you may need to go back to the original specs and make some adjustments before mass assembling the final PC boards.

A Never Ending Cycle
Even after a prototype has been approved for mass production and has made its way to the end user, its evolutionary cycle is never actually complete. As technology advances, it will be discovered that the existing device can be improved upon, or even eventually replaced, by something better, but that's what makes the world of technology so exciting! As long as dreamers are coming up with new ideas, we'll be ready to take on the challenge of developing prototypes that may end up changing the world.

PCBA Function Test----Wonderful PCB(hk)Limited

PCB Boards revolutionized electronic devices by drastically reducing the size. They opened new avenues to fix the complex circuits and different components firmly and to cut the size significantly. Various aspects of PCB Boards are examined here.
Electronic devices have a cumbersome structure beneath the appealing surfaces. Most of them are the essential parts of a device. A lot of components made up of different compounds are connected to each other in a haphazard way, at least appears so to a lay man. But the truth is they are planted in such a systemic, organized way that can never be understood but only by the smooth functioning of the device. The key component which held all the electronic circuits together, including chips depending on the type of device, is Printed Circuited Board. actually a flat board with a coated surface, the only way with which all the components and circuits can be held together and firm.
Aluminum pcb constitutes an essential part of almost all electronic devices. The more sophisticated the device, the most important of such a board in it. It mechanically supports the different conductive pathways. These Circuit Boards are generally made up of insulating material. Usually, with the help of acid, etches are made in the board to create electricity pathways. Most of the electronic circuits are manufactured using Printed Circuited Boards. The complex electronic circuits without PCB Boards would have been impossible to make. The circuits are mounted on the board and soldiered. It is this Printed Circuit Board that changed the dynamic of electronic devices, particularly the sizes of devices. The great shrink could be possible only because of the PCB Boards. These enabled to come up with compact and smaller circuits and can be placed on a board steadily. It also helped to fix the resistors and capacitors firmly to the board leaving no chance of different components coming into contact and causing damage.
The Printed Circuit Boards are made-up of glass reinforced plastic with copper tracks as replacement to the regular wire. Components are fixed either by adhesives are drilling into the board so as to remain firm. Circuits and connection can be ensured through locating and soldiering the components. The wire replacement copper tracks link different components and completes a circuit. Circuit Boards are present in a host of electronic devices. All most all the devices found in the home consist of one or the other type of Printed Circuit Boards. Television, Computers; laptop and desktop, music systems phones, Owens and what not everything consists this PCBs, Few devices in a multiple numbers. The examples of few such boards in the computer include mother boards, Audio and Video cards and RAM etc.

Prototype PCB Necessity and Benefits(1)----Wonderful PCB (hk) Limited

PCB prototype plays a very important role in the creation and design of PCB (Printed Circuit Boards). The design of the Rigid-flex pcb does not depend on single elements rather depends on variety of elements which needs expertise and testing for several times. And prototype gives you the opportunity to check your product before production. Actually, we can say that the design depends on indistinct set of necessities. This is produced to define the required functions for the electrical and mechanical products. And the prototype helps to fulfill these needs by giving you a chance for proving your design.
The designers include all the required functionalities those can fit in the board. As regarding to the requirements, the board changes its shape. Sometimes it's large with the extensive requirements. And sometimes it's small with fewer requirements. Again many things are needed to make a PCB prototype of production stage. Among them, functionality with reliability is a must. The complexity and functionality determines the required number of layers. Some board consists of only two layers as they have less functionality and some have even more than 32 layers for their complexity and high functionality. And the size also differs a lot. As the board has to sit perfectly into its desired system, it must be made in the perfect shape. The tolerance is also a factor as the layers and copper traces certainly depend on it. Most PCB has a design with a tolerance that makes the layers and copper traces even more critical. As they are designed with highly tight tolerances, they are made highly integrated. And this integrity sometime causes some critical problems. So, it must be checked carefully for the accuracy. The voltage must be moderate with the application and the signals must also be clean. Again, the surface components must meet the required tolerance. And after considering all these respects, the developed first board is called the prototype. These are developed for testing. They are mainly made depending on the number of testing required. After the testing is completed, the production begins with the design.

Component placement

Cloth of PCB board in the process, the system layout is completed, to review PCB figure, look at the layout of the system is reasonable, whether can achieve the optimal effect. Usually can be examined from the following several aspects:
1. The system whether guarantee reasonable wiring or optimal layout, wiring whether can guarantee the reliable and can ensure the reliable of circuit. When the layout of the need of the signal and the direction of the power and ground network have a whole understanding and planning.
2. The PCB size is consistent with the processing drawing size, can meet the requirements of PCB manufacturing process, any behavior. Don’t pay attention to this need, a lot of PCB circuit layout and wiring design beautifully, reasonable, but neglect the precise localization of locating connectors, lead to can't and other circuit docking design.
3. Components in 2 d and 3 d space without conflict. Pay attention to the actual size devices, especially the height of the device. Yuan device, layout of the welding from altitude generally no more than 3 mm.
4. The component layout density and orderly, neat rows, whether all the cloth. When components layout, not only to consider the direction of the signal and the signal types, need to pay attention to the places or protect, also want to consider the overall density of the device layout, density uniformity.
5. Often need to change the components can be easily replaced, whether it's a good card inserted into the device. Often should guarantee the change of components of the replacement and plug is convenient and reliable.
6. Pay special attention to when the layout of the radio frequency part, should avoid to radio frequency interference of other components, so must be isolated.

WonderfuI Printed Circuit Board

   Flying Probe Tester is a test PCBA manufacturer environment system. Instead of using the conventional on-line testing machine all conventional needle bed (bed-of-nails) interface, flying probe test uses four to eight independent control of the probe, is moved to the test element. In the measurement unit (UUT, unit under test) supplied to the testing machine by a belt or other transmission system UUT. Followed by fixing the probe tester to test pad (test pad) and a via hole (via) was tested for in a single element measuring means (UUT) is. Test probe connected via multiplexing (multiplexing) to the drive system (signal generator, power supply, etc.) and sensor (DMM, frequency counter, etc.) to the test element on the UUT. When a component is being tested, and other components on the UUT through the probe electrically shielded to prevent interference readings (Figure 1).
    Flying Probe Tester can check the short circuit, open circuit and component values. On the flying probe test also uses a camera to help locate the missing elements. With a camera to check the direction clear element shapes, such as polar capacitors. With the probe positioning accuracy and repeatability reach 5-15 micron range, flying probe tester can accurately detect UUT.
    Flying Probe Test solve a lot of the current problems in PCB assembly to see, such as the lack of a model in the development of gold (golden standard board). Problems may take up to 4-6 weeks also includes test development cycle; about $ 10,000- $ 50,000 a fixture development costs; not less economically test production; and the inability to quickly test the prototype (prototype) assembly. These cases illustrate, the traditional test-bed tester lack of low cost production system; lack of a quick test prototype assembly cover; and can not test to shield assembly.
    Because the ability to have close contact with the UUT shielding ability and help reach the market faster (time-to-market), the flying probe test is an invaluable resource production. Further, since no test development engineer experienced, the system can be considered as having the added value of savings in equipment and time savings and other benefits of manpower.
