The main advantage of using printed circuit board

Circuit boards, We also named PCB printed circuit board, also known as the provider of the electrical connection in the electronic components.It has a history of more than 100 years of development; The design of the PCB manufacturer mainly layout design; The main advantage of the circuit board is greatly reduce wiring and fitting error, improves the automation level and rate of productive labor.

With the rapid development of electronic technology, PCB circuit boards are widely used in various fields, almost all of the electronic devices are included in the printed circuit board.To guarantee the normal work of the electronic equipment, reduce the electromagnetic interference between each other, to reduce the negative impact of the electromagnetic pollution to human and ecological environment, electromagnetic compatibility design cannot be ignored.

The main advantage of the PCB manufacturer use the PCB as fellows:

1. because the graphics has repeatability, reproducibility and consistency, reduce the wiring and assembly errors, saved the equipment maintenance, debugging and testing time;

2. Design can be standardized, conducive to swap;Printed circuit board

3. Wiring high density, small volume, light weight, good for the miniaturization of electronic equipment;

4. Good for mechanization and automation of production, improve the labor productivity and reduce the cost of the electronic equipmen

5. in particular, FPC soft plate bending resistance, precision, better should be on High precision instruments. (such as camera, cell phone. The camera, etc.).

Printed circuit board manufacturing method can be divided into minus (subtraction method) and add (addition) two kinds big.At present, the large-scale industrial production is given priority to with minus the corrosion of the copper foil method.

IPC World Aluminum PCB Production Report

The world market for printed circuit boards (PCBs) reached an estimated $60.2 billion in value in 2014, growing just 0.7 percent in real terms, according to IPC’s World PCB Production Report for the Year 2014. Production growth in China, Thailand and Vietnam compensated for declining PCB production in most other regions,especially Aluminum PCB.Developed by a team of the world's leading PCB industry analysts, the annual study is the definitive source of PCB production data, indicating the volumes and types of PCBs being made in the world’s major producing countries.



The IPC report contains estimates of 2014 PCB production value by nine product categories and by 30 countries or sub-regions. Four categories of rigid PCBs, three categories of flexible circuits, and IC substrates are covered. The standard multilayer rigid PCB values are further segmented by those having microvia structures and those with non-microvia structures. The report also includes updates on metal-core PCBs, as well as regional trends and historical data on regional shifts in PCB production.



The data show that the worldwide rigid PCB market grew modestly in 2014, while flexible circuit growth was flat. Regional trends are also examined, including China's slowing production growth and the spectacular growth in the PCB industries of Thailand and Vietnam.



“PCB production is an international business and the landscape continues to change,” says Sharon Starr, IPC director of market research. “Companies based in Taiwan, Japan and South Korea, are responsible for more than two-thirds of world PCB production. These and other companies around the world are powering the impressive growth of PCB production in southeast Asia.”

How PCB Board Manufacturer Control Quality

“Quality is the life of PCBs and technology is a source of strength for PCBs” as all is know. The pursuit for good service is Wonder PCB (WDF) principle of service. WDF has a good quality assurance system and high quality technical service team. High quality products not only in China but also in the world are highly welcomed. WDF has focused on the high-precision technology, stable supply of our production system. All of our products are carried out strict quality management, strict quality testing , relied on high-precision design in all processes, as well as many excellent trained personnel and sophisticated equipment.

 

1. Raw material test 

 

All of our raw materials must get through strict test before production. Sometimes, the raw material samples will be conducted to special tests to meet customer requirements in independent laboratories. All classified pcb material will be marked so that production can track the original source at any time.

 

2. Interim Inspection 

 

Each stage of our production is monitored by the mid-term test. Each stage of our production on the first items is tested. After completion of the survey is confirmed by the adoption of quality control manager, we can begin volume production. Each machine operator in the production process will conduct the testing. Inspectors will regularly check each machine.

 

3. End of the test 

 

All the documents are signed, stamped and certified by both parties,  the company can only work out the appropriate product database. Our quality control objective is to achieve zero defects in 100% of manufactured goods.

 

4. Environmental Protection 

 

We do not use certain hazardous substances for our productions. In recent years, restrictions on harmful chemical substances to the environment continued to strengthen the use of the law. According to EU (European Union) ROHS (the Restriction of the use of certain Hazardous Substances, Specific Restriction of Hazardous Substances), electronic products contain six kinds of specific prohibited substances, such as: lead, mercury, hexavalent chromium, cadmium, brominated flame retardants specific (PBB, PBDE). This is based on protecting the global environment from the start so that we can establish the behavior of corporate social responsibility, and, in the future the standard will not be limited to the public within the EU, it will gradually become a worldwide environmental standards. WDF promise that all products will implement the EU RoHS standards, occupational health and safety policy. We agree with the other requirements. For example, we reduce health and safety risks for social progress and offer well-being of employees to make their own contribution.

Guides on PCB board Copying

How to copy a PCB board? It seems quite difficulty, but here, you will get the answer.
Actually, copying a printed Circuit Board is not so trouble and will reduce your price on buying a new pcb.

1. Get a piece of PCB, record all the strength of the model, parameters, and location, especially the diode, the direction of the three machine, IC gap directionon the paper. It is best to use a digital camera to take pictures of the components location.

2.Remove all the deviceand the tin in PAD hole.Usealcohol to clean thePCB, put it into the scanner, start POHTOSHOP, screen printing surface in the mode of color and print out the spare.

3. Use water-proof abrasive paper to slightly polishTOP LAYER and BOTTOMLAYER until the copper film starts shining, put it into the scanner, start PHOTOSHOP,color scanning the 2 layers respectively . Note that the position of them in the scanner must be horizontal or straight trees, otherwise, the scanning pictures will be useless.

4. Adjust contrast ratio, brightness of the canvas so that there will be strong comparison of the parts with copper file and part without copper film.Then convert this figure into black and white, check if the line is clear or not. If not clear, repeat this step. If clear, save it with the format of black and white BMP, TOP.BMP and BOT.BMP.

5. Transferthe two BMP format files into PROTEL format respectively and input the two layers to PROTEL. If the pad and via position of the two layers can be coincided, it shows that the first few steps were well done.If there is a deviation, then the third step should be repeated.

6.Transfer TOP.BMP into TOP.PCB. Note that it should be transferred to the SILK layer, also the yellow layer,then you can draw the line in the TOP layer. Then you can put the components based on the drawing in step 2. When finished, delete the silk layer.

7.Import TOP.PCB and BOT.PCB in the PROTEL and combine them into one graph,that will be ok.

8.Print TOP LAYER, BOTTOM LAYER into transparencies (1:1 ratio) respectively by a laser printer. Put the film on thePCB and compare if there is any error. If no, ok, you will be accomplished.

Daily work of a PCB trader

 ShenZhen is a city with high pace. It is just like a program that everyone is doing his own part to make sure the program(city, country) can be functioned normally. Work, off work and work. From a macro perspective, it looks rigid and boring.However, when it comes to an individual, things is much different, every one from different field is leading a colorful and fulfilling life. Here I would like to introduce the daily work of a PCB trader.

What’s the most import for a PCB trader, of course it is the customer. So every detailed job a trader do is closely connected with the customer.

1. Search for customers and send developing email. 

From some business platform such as Alibaba and Global Source, you may get some inquiries PCB Manufacturer. However, that’s far from enough. In sales industry, there is a saying goes that as a International trader, it is your customer from any other platforms except for Alibaba and Global Source that proves your ability. So to increase your performance and show your ability, search for customers and send developing emails is a must. You can search from all kinds of platforms such as google, facebook, linked in, twitter and other websites. Only if you can find customer, any way is acceptable.

  2. Deal with inquiries and send quotation. 

After first step, you will have some inquires, they will ask for exact quotation. For a PCB trader, you must make sure they have gerberfile and inform you the quantity. If they can provide, then things become easy. Send gerberfile to engineer for technical data, share the bom list to purchaser to get a best price for electronic components. After that, you need to calculate the PCB price and combine it with component price, find a suitable time to send the quotation to your customer for PCB prototypes producing. The reason why I emphasis on suitable time is because of time lag from different countries. It will be much more useful if you can send the quotation when they’re on work. After that, what you need to do is to wait for reply and follow up in a timely pace.

      3. Negotiation. 

This is the most challenging job and I like it best. After your quotations, there maybe some customers that interest in your PCB, PCBA, or any others, they will reply you and keep contact with you and negotiate with you to get a best price. Based on my experience, the India like to bargain the most and most European customers would not like to do that. Sometimes you may feel boring and angry when a customer force you to price down, but most of the time you may feel excited and a sense of achievement when you win the fight.

     4. Production. 

When you win the price fight and get an order from your customer, you need to arrange the production and update the progress to your client timely. Besides, you need to confirm every detail with your factory and customer in case of any error. So you must be a careful person and at the same time good at communication. 

     5. Shipping. 

After production finished, you need to ship the PCB or PCBA. If your customer have his own shipping agent, it is easy, what you will do is just deliver the goods to the agent he specified. However if he don’t have shipping agent and account, you need to contact you own shipping agent to ship. Besides, for the goods with total value more than 5000rmb,you need to prepare the customs clearance.

     6. Feedback. 

Once your customers get the PCB, he may do some test to match his end product, if the your PCB can’t pass the test, you need to keep in touch with him and re-manufacture for them when needed. Only in this way can you have a good business relationship with your customer and they may place repeat order for you.

   

A Beginners Guide to Printed Circuit Boards

New to PCB and Want to know what is pcb, and how is pcb can do for you. Well, this is the guide for you. Printed Circuit Boards (PCBs) are integral in our highly digitized world. They connect different electronic components in a device. A PCB consists of a substrate, electronic components, and copper traces. The base of the PCB itself is non-conductive but copper lines are etched on this base so as to electrically connect the different components. PCBs ensure precision and high-speed connectivity while being rugged in nature.Types of Printed Circuit Boards:





There are three kinds of PCB as below:

1. Single Sided Board: This kind of PCB, as the name suggests, has a single substrate. The electronic components are mounted on one side and the copper traces are etched on the other. The simplest of its kind, single-sided PCBs are used when the circuitry is simple and the budget is low.

2. Double Sided Board: Like the single-sided board, this PCB consists of a single substrate. The difference lies in the electronic components and copper traces, which are mounted and etched on both sides of the board. Thus, the number of components and conductor lines are much higher in a double sided board than in single-sided boards. This type of PCB uses through-hole and surface-mount construction to assemble the different components.

3. Multi-Layered Board: This PCB type consists of several circuit boards connected together. The copper traces connect the different layers by means of small plated-through holes called vias. Multi-layered PCBs are always connected in even numbers. When additional circuits are connected, heat becomes a problem. This brought up the need to insulate the layers. Thus, an insulating material is placed between two layers. This PCB type is used in extremely complex applications that demand high-density connections such as computers, cars, mobile phones and military equipment among others.

A thorough understanding of the various types of PCBs will help the user match the right type of circuit board with his application. The complexity of the circuit would determine the usage of the correct PCB.
