How to communicate with customers in the trade show

To ask more and listen more to get what customer need.
In fact, in the show, the audience came to the booth is not necessarily talk about the business, to be an exhibitor you need to ask more about what help they need, listen more about the issues raised by customers about the products.
As an exhibitor should do what points: First, to know that your guests what kinds of requirements they need about the product. Second, if they do not understand the product, we must follow our own ideas to guide guests. Of course, if you already make an appointment before the show with a good client, before the customer to view exhibitions, it is necessary for you to get a detailed understanding of the product, then we can give customers a satisfactory answer.
"Positive question" is nothing new. Before seeking for the understanding from others, you have to understand others. Before responding to the customer's words, you need to make sure you have already understood their words.
The basic strategy of "positive question" behind is the "safe zone" concept. It enables you to search for specific information which can be quantified, such as what the client's goals are, what his selection criteria, which he hopes to quantifiable gains, what's evaluation system he uses. As a result, customers will treat you as a real expert.

Following will be continued in next chapter.

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.

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.

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
