How to follow a new customer






For many new sales, they find that it is hard to start a new business with a new customer. They always make things worse when make a quote , or make a negotiation to their customer. So today we are going to talk about this.

Generally speaking, one would begin to send developing e-mail to customer. Time by time, some customers would give you some feedback. They would ask for an inquiry from you. For example, you are selling PCB and PCBA. They would send to the gerber files and bom list to quote. If you can insist to this step. You have got the key to the success. What you need to do is evaluating the files and make a reasonable price for your customers. But most of the time , when you send the quotation and then you get nothing from you customers. This bothers many of the sales. When this happens one and another. It would beat down the sales sometimes and make them begin to be passive and don’t know how to follow a new customer, even someone begins to lose confidence on himself.

So we need to do something to change this situation. Firstly, as a sale, you should keep a active attitude all the time. You send 1000 e-mail one day and get one feedback, even nothing back. You may tell to yourself that it is normal. Maybe the customers have too many e-mail to deal with and don’t note your e-mail. Maybe your e-mail can’t get to your customers’ server. These things happen everyday in every moment. So you need to try to write a good title of the developing e-mail to attract customers’ eyes. And keep send e-mails everyday. Secondly, when you make a quote to customers, you should evaluate this customer at first before you make a quote. You should know where is the customer and why he needs your PCB and PCBA. And then you make a reasonable for your customers. You know in Europe and American countries, you may make a higher quote ,but in Africa and India, you can’t do like that. So evaluating your customers should comes first. Thirdly, you should keep frequently sending your e-mails or make a phone call to your customers. Choose the working time to send or call and don’t make a disturbing to clients. Be polite and easy going to your customers in call to make a good impress. Last one rule, don’t be rude even if you cann’t make a agreement with your customers. Just keep in good contacting with your customers and maybe he would give you order in the next time.

Finally, the most important one, you should keep on doing the above four rules and i believe that one day you would success.

How to design a PCB( Printed Circuit Board ) ?

WDF-FPC-M-37,4 layer,wonderfulpcb.com

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coated on the blank copper-clad boards.

Nowadays PCBs are designed with dedicated layout software, generally in the following steps:

1.Schematic capture through an electronic design automation (EDA) tool.

2.Card dimensions and template are decided based on required circuitry and case of the PCB.

3.The positions of the components and heat sinks are determined.

4.Layer stack of the PCB is decided, with one to tens of layers depending on complexity. Ground and power planes are decided. A power plane is the counterpart to a ground plane and behaves as an AC signal ground while providing DC power to the circuits mounted on the PCB. Signal interconnections are traced on signal planes. Signal planes can be on the outer as well as inner layers. For optimal EMI performance high frequency signals are routed in internal layers between power or ground planes.

5.Line impedance is determined using dielectric layer thickness, routing copper thickness and trace-width. Trace separation is also taken into account in case of differential signals. Microstrip, stripline or dual stripline can be used to route signals.

6.Components are placed. Thermal considerations and geometry are taken into account. Vias and lands are marked.

7.Signal traces are routed. Electronic design automation tools usually create clearances and connections in power and ground planes automatically.

8.Gerber files are generated for manufacturing.

How to customize a PCB ?


As a customer of PCB industry, you may often ask: How can I customize a PCB board? Why can’t the PCB manufacturer ( or PCBA manufacturer ) follow my requirements?

Actually, you should ask yourself first: Have I got a design document?

Well, to customize a PCB board, you need to offer a design document first which is called a “Gerber file”, it is used to describe your requirements for the PCB board you’d like to customize.

What will be contained in a Gerber file?

① Layer count
② Delivery size
③ Surface finished (such as: HASL, ENIG)
④ Material (such as: FR1, FR4,FR2, CEM-1)
⑤ Board thickness
⑥ Copper thickness
⑦ Solder mask

Items above, they make it each other possible. Otherwise, it may cost engineering problems.

Is it absolutely necessary to have a Gerber file?

Fortunately, it is not if you happened to have a sample PCB board and want a large number of that. You simply send the sample PCB board to the PCB manufacturer works for you, and then all you need to do is enjoying a short wait until the PCB manufacturer send back a host of PCBs, each one of which is the same as the one you send to them.

For PCBA, a BOM list ( BOM-Bill of material ) is necessary during customization.

Pay attention that you should make sure the list providing as many details as possible about the used materials. Otherwise, it may cost engineering problems.

In conclusion, if you want to customize a PCB board or get some PCBA services, you need to find a high quality, experienced PCB manufacturer or PCBA manufacturer and offer your Gerber file, sample PCB board, or BOM list as your requirements.

PCBs Fabrication of Exposure---WonderfulPCB(hk)Limited

The photo resist board needs to be exposed to ultra-violet light through the artwork, using a UV exposure box.

UV exposure units can easily be made using standard fluorescent lamp ballasts and UV tubes. For small PCBs, two or four 8 watt 12" tubes will be adequate, for larger (A3) units, four 15" 15 watt tubes are ideal. To determine the tube to glass spacing, place a sheet of tracing paper on the glass and adjust the distance to get the most even light level over the surface of the paper. Even illumination is a lot easier to obtain with 4-tube units. The UV tubes you need are those sold either as replacements for UV exposure units, insect killers or 'black light' tubes for disco lighting etc. They look white or occasionally black/blue when off, and light up with a light purple, which makes fluorescent paper etc. glow brightly. DO NOT use short-wave UV lamps like EPROM eraser tubes or germicidal lamps, which have clear glass - these emit short-wave UV which can cause eye and skin damage.
A timer which switches off the UV lamps automatically is essential, and should allow exposure times from 2 to 10 minutes in 15-30 second increments. It is useful if the timer has an audible indication when the timing period has completed. A timer from a scrap microwave oven would be ideal.

Short-term eye exposure to the correct type of UV lamp is not harmful, but can cause discomfort, especially with bigger units. Use glass sheet rather than plastic for the top of the UV unit, as it will flex less and be less prone to scratches.
If you do a lot of Multilayer pcb, it may be worth making a double-sided exposure unit, where the PCB can be sandwiched between two light sources to expose both sides simultaneously.

You will need to experiment to find the required exposure time for a particular UV unit and laminate type, expose a test piece in 30 second increments from 2 to 8 minutes, develop and use the time which gave the best image. Generally speaking, overexposure is better than underexposure.

For a single-sided PCB, place the artwork with toner side up on the UV box glass, peel off the protective film from the laminate and place it sensitive side down on top of the artwork. The laminate must be pressed firmly down to ensure good contact all over the artwork, and this can be done either by placing weights on the back of the laminate, or by fitting the UV box with a hinged lid lined with foam rubber, which can be used to clamp the PCB and artwork.

PCB Test

More intensive PCB, higher bus speeds and analog RF circuits, etc. have put to the test with unprecedented challenges , this environment functional test requires careful design and thoughtful testing methods and the proper tools in order to provide credible test results , adequate preparation and careful screening tool will be able to achieve a multiplier effect .
Significance

Functional test is becoming more and more important , however, the online tests, and the PCB board design technology development test range will be limited. Although the programming software environment has made great progress, help to overcome some of these difficulties , but if you want to follow your successful implementation of functional testing test strategy , there are many issues that need to be done to avoid and more thorough preparation . This paper describes the successful implementation of functional testing should consider a number of factors and coping methods and strategies . Electronic functional test has its ups and downs of history, the late 1960s it was the first automated test method , with the late 1970s online testing technology, functional testing seems destined to give way to determine the increasingly quick and easy programming and online test . Today, however, the trend has changed. Online testing is currently a growing problem , namely detection methods . According to the U.S. NEMI ( National Electronics Manufacturing Organization ) analysis can detect the end of 2003 nodes essentially zero, if unable to be detected , then the online test almost useless.

Function test is increasingly more for the production line process, even used for the middle of the test process , but the system and method of the previous embodiment is almost completely different tests . Today, in most cases, the test system is faster and more compact structure , function test for verifying the overall functionality of the product , maintenance, calibration information , provides data to ISO9000 and to ensure high-risk products , such as medical equipment, quality , etc. are indispensable.

PCB design and PCB manufacture

In the increasing developed electronic industry, no matter manufacturing for a large multinational tech company or a small electronics company, PCB assembly can be riddled with numerous challenges. Effective assembly requires smooth collaboration between designers, fabricators and manufacturers in order to deliver a high quality circuit board to the market. Mistakes made in design can hold grave consequences to the whole organization, especially where the design failures result in substandard products reaching the market.

Design Services
The design of PCB board (PCBs) is one of the most important steps in manufacturing a quality electronic device. The functionality and efficiency of your electronics depend on the design and layout out of the board (or "brain") of the gadget, meaning that nothing can be left to chance. Through careful attention to detail, the board can be designed to meet all product specifications without wasting any space or utilizing excessive components. A truly qualified electronic design and manufacture contractor can provide you with numerous solutions throughout the design process, such as:

Prototyping - If you have an idea for a device, it can be created - as long as you have the right resources at your fingertips. The design services provided by PCB Company can help to bring your prototype to life, quickly and efficiently. The fast-turnaround will enable you to familiarize yourself with your device, so that you can explain and present it to your prospect clients for future orders. And careful, detailed planning ensures that your product will operate without a hitch.

Review - These individuals have years of industry experience, enabling them to quickly spot any flaws in your design schematics, or areas that could be improved. Ultimately, this could result in more compact, affordable boards, and a faster, more efficient device.

Reworking - In some cases, your team may be stuck on a problem with one of your boards. However, engineers could have experience to help to check and rework these problems.

Manufacturing Assembly Services

It's very important to turn your designs into a reality with skill, speed, and precision.

Skillful assembly production - A reliable electronic design and manufacture company will have a comprehensive understanding of the demands of systems assembly. Assembly Company should have the ability to provide you with a customized solution that may include services like configure/build to order, assembly at the chassis, cage, or rack level, custom cabling, documentation, etc. All of this should be handled in direct compliance with industry standards.


Troubleshoot and repair - Beyond manufacturing, your third party contractor should stand behind its electronic design and manufacture services to the point where it offers troubleshooting and repair for the devices that it produces. By taking the time to systematically seek out the underlying issue at its source, your partner company can help you to repair your boards without being forced to replace the unit entirely. This helps your business to save significantly on time and money.

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 PCBA manufacturer 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 PCB 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.

PCB Board and Its Advantages to the Industrial Setups 2----Wonderful PCB(hk)Limited




For the traces in the PCBs, copper is used as the most used material. Mechanics use several distinct methods to plating the entire board with copper. They then follow etching away process to uncover the traces from unwanted areas.

Engineers use more complex and critical methods to allow traces to be installed on to a bare Aluminum pcb board. During the fabrication process, some PCBs require the use of gold. This component is used for more sensitive, low-voltage applications or lead-free compliances. Use of nickel can be a huge loss to impedance in compare to a gold element.

If you are also interested to design and develop PCB boards you should spend a considerable amount of time to understanding the basics and advance logics of the prevailing   PCB designs in the electronics industry. You can take the advantage of a number of guide books and tutorials available in the market place.
