Well Known Aluminum PCB Manufaturer

If you are looking for PCB manufacturer in Aluminum PCB material, this can be the best for you. Aluminum PCB manufacturer is not easy to dealth with, well let' s have a know on Aluminum PCBs. Aluminum Printed Circuit Board is also named Aluminum clad, Metal clad (MCPCB), Thermally conductive PCBs, Insulated Metal Substrate (IMS or IMPCB),aluminum base PCB, etc., is often used in LED lighting products and power hybrid IC (HTC),it is a metal-based CCL which has good heat dissipation function. Normally, single sided board is consisted of three layers: circuit layer (copper foil), insulation layer and metal substrate.

Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat。There are many names for these products; Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs,etc… but they all mean the same thing and perform the same way.

How Layers Are Aluminum PCBs Made

A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric。

Benefits of Aluminum PCBs

Heat dissipation is dramatically superior to standard FR-4 constructions.The dielectrics used are typically 5 to 10 times as thermally conductive as conventional epoxy-glass and a tenth of the thicknes.Thermal transfer exponentially more efficient than a conventional rigid PCB.Lower copper weights than suggested by the IPC heat-rise charts can be used.

Applications of Aluminum PCBs

Although Power Converters and LEDs are the largest users of these products, Automotive and RF companies are also looking to take advantage of the benefits of these constructions.
While a single layer construction is the simplest, other configuration options are available at Amitron, including:Flexible Aluminum PCBsFlex.One of the newest developments in IMS materials is flexible dielectrics. These materials.feature a polyimide resin system with ceramic fillers which provides excellent electrical insulation, flexibility and of course thermal conductivity. When applied to a flexible aluminum material like 5754 or similar, the product can be formed to achieve a variety of shapes and angles which can eliminate costly fixtures, cables and connectors. Although these materials are flexible, they are intended to be bent into place and remain in place.They are not suited for applications that are intended to be flexed regularly.

Aluminum PCB for LED

LED heat dissipation problem is LED manufacturers the most difficult problem, but can be used aluminum plates, because of the high thermal conductivity of aluminum PCB, heat, and can effectively export the internal heat. Aluminum plate is a unique metal-based CCL, with good thermal conductivity, electrical insulation properties and machinability. We should try to be close to the aluminum base PCB design, reducing the thermal resistance potting segment generated.

Multilayer Aluminum PCBs

Common in the high performance power supply market, multilayer IMS PCBs are made from multiple layers of thermally conductive dielectrics. These constructions have one or more layers of circuitry buried in the dielectric with blind vias acting as either thermal vias or signal vias. While more expensive and less efficient at transferring heat as a single layer designs, they provide a simple and effective solution for heat dissipation in more complex designs.

PCB Assembly

After the printed circuit board (PCB) is completed, electronic components must be attached to form a functional printed circuit assembly, or PCA (sometimes called a "printed circuit board assembly" PCBA). In through-hole construction, component leads are inserted in holes. In surface-mount (SMT - surface mount technology) construction, the components are placed on pads or lands on the outer surfaces of the PCB. In both kinds of construction, component leads are electrically and mechanically fixed to the board with a molten metal solder.

 

There are a variety of soldering techniques used to attach components to a PCB. High volume production is usually done with SMT placement machine and bulk wave soldering or reflow ovens, but skilled technicians are able to solder very tiny parts (for instance 0201 packages which are 0.02 in. by 0.01 in.) by hand under a microscope, using tweezers and a fine tip soldering iron for small volume prototypes. Some parts may be extremely difficult to solder by hand, such as BGA packages.

 

Often, through-hole and surface-mount construction must be combined in a single assembly because some required components are available only in surface-mount packages, while others are available only in through-hole packages. Another reason to use both methods is that through-hole mounting can provide needed strength for components likely to endure physical stress, while components that are expected to go untouched will take up less space using surface-mount techniques. For further comparison, see the SMT page.

 

After the board has been populated it may be tested in a variety of ways:

 

While the power is off, visual inspection, automated optical inspection. JEDEC guidelines for PCB component placement, soldering, and inspection are commonly used to maintain quality control in this stage of PCB manufacturing.

While the power is off, analog signature analysis, power-off testing.

While the power is on, in-circuit test, where physical measurements (for example, voltage) can be done.

While the power is on, functional test, just checking if the PCB does what it had been designed to do.

 

To facilitate these tests, PCBs may be designed with extra pads to make temporary connections. Sometimes these pads must be isolated with resistors. The in-circuit test may also exercise boundary scan test features of some components. In-circuit test systems may also be used to program nonvolatile memory components on the board.

 

In boundary scan testing, test circuits integrated into various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted correctly. Boundary scan testing requires that all the ICs to be tested use a standard test configuration procedure, the most common one being the Joint Test Action Group (JTAG) standard. The JTAG test architecture provides a means to test interconnects between integrated circuits on a board without using physical test probes. JTAG tool vendors provide various types of stimulus and sophisticated algorithms, not only to detect the failing nets, but also to isolate the faults to specific nets, devices, and pins.

 

When boards fail the test, technicians may desolder and replace failed components, a task known as rework.

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.

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.

PCBA called live-fire circuit board. In the process of mass production of PCBA, due to the equipment and the operator of a variety of possible factors, cannot guarantee to produce PCBA all was in good taste. This requires that join at the end of the production of various test equipment and test tools, in order to make sure all the live-fire circuit board factory are in complete accord with various specifications and parameters of design. This leads to the ICT, AOI and X - Ray, a Boundary Scan, FCT has grown and other test means.

Aluminum alloy and aluminum common surface treatment

Aluminum alloy and aluminum usually need to meet the demands of different surface treatment, common treatment over the surface of aluminum alloy electroplating, painting, drawing, anode, sandblast, passivation, polishing, oxidation film processing, etc.
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.

PCB board, MOQ 1PCS, Delivery time fastest 1day

   CNC drilling, cutting edge, light painting, etching production process, only for less demanding customers, providing fast, cheap proofing services. No drilling metal plating, no character screen (single layer PCB can be printed in black silkscreen ), solder green oil, only suitable for the experiment, manual welding, can also be used to check for errors before production. Because no drilling metal plating, double panel vias problem Check "vias solution", or modify files, avoiding component pins and vias, shop may be able to modify the file, because vias can resolve threading welded at both ends, but if the pin element and vias, there may be elements blocked welding end less, so to avoid component pins and vias; pad line to be set a little rough, welding is best to use low-temperature solder (shop for sale ). Recommended not to do, of course, if a lot of your money, we do not oppose the demanding user is recommended to do the whole process. 16:30 hours before delivery traded at 22:00, 16:30, if the transaction had to be postponed until 22:00 the next day will delivery.
