What should be paid attention to in PCB proofing?

The Chinese name of PCB is printed circuit board , also known as printed circuit board, printed and is an important electronic component. As the support of electronic components, it provides electrical connection of electronic components. Because it is manufactured using electronic printing, it is called a "printed" circuit board. PCB proofing refers to the trial production of printed circuit boards before mass production. Generally, it means that electronic products are sent to pcb manufacturers to be processed into pcb boards after the engineer pcb layout design is completed . The update and iteration of electronic products are relatively fast, so the demand for pcb proofing is also gradually growing, and the market share is constantly expanding. As the technological requirements of electronic products are getting higher and higher, and the information is getting faster and faster, resulting in the increase of multi -layer PCB proofing faster.

1. There are two ways for proofing: regular PCB factory and professional sample company. In your situation, it is better to find a proofing company. They make a living by charging for proofing, and they will definitely accept your requirement to make only two pieces.

2. The purpose of proofing in a regular factory is to have bulk orders, so of course, it is expected to return the order; the proofing company itself only makes samples or small batches, and he can't do it even if you have a large order for him. 3. In terms of quality assurance, the regular factory must be better than the model company. The model company buys and sells the model with a hammer and collects money. There is no need to do the flying probe test. Money; regular factories generally do flying probe tests, from materials to craftsmanship are detailed and professional, so the quality is often successful at the first time.

1. Precautions for PCB proofing

As a collective of engineers, the precautions for PCB proofing are:

1. Carefully select the number of samples to effectively control the cost.　　

2. Specially confirm the packaging of the equipment to avoid the failure of proofing due to packaging errors.　　

3. Conduct a comprehensive electrical inspection to improve the electrical function of the PCB board.　　

4. Do a good job of signal integrity layout, reduce noise and improve PCB stability.     

As a PCB proofing manufacturer, the precautions for proofing are:

1. Carefully check the PCB file materials to avoid material problems.    

2. Carry out process approval in an all-round way, and carry out process configuration with its own manufacturers.

3. Control the production quantity, reduce the cost and take care of the quality.   

4. Communicate precautions with proofing customers to prevent incidents in advance.

2. PCB Proofing Market Distribution

The demand for PCB proofing is mainly concentrated in areas where electronic products are relatively developed, mainly in Shenzhen, Beijing, Shanghai, Suzhou, Hangzhou, Xi'an, Chengdu, Changsha and other cities.

The user group of PCB proofing is mainly electronic engineers, but also a group of students for academic research, research institutes and so on.

3. How to choose a suitable pcb proofing manufacturer

First pay attention to a few aspects:

1. Select large companies and large enterprises, the relative strength is more guaranteed, and the management is more standardized.

2. Select Shenzhen surrounding enterprises, the forefront of electronic products, complete supporting facilities to ensure delivery.

3. Select a company with a good reputation, pay attention to service, and have a good civilized theme.
