PCB News - The difference between PCB manufacturing and proofing? Precautions for PCB proofing!

The Chinese name of PCB is printed circuit board, also known as printed circuit board, printed circuit board, which is an important electronic component. As the supporting body of electronic components, it provides electrical connection of electronic components. Because it is manufactured by electronic printing, it is called a "printed" circuit board. PCB proofing refers to the trial production of printed circuit boards before mass production. Generally, electronic products are sent to the PCB manufacturer to be processed into PCB boards after the engineer's PCB layout planning is completed. The update iteration of electronic products is relatively fast, so the demand for PCB proofing is gradually growing. The market share is constantly expanding. As the process requirements of electronic products are getting higher and higher, the information is getting faster and faster, leading to the increase of multi-layer PCB proofing faster.

1. Proofing can be divided into two ways: regular PCB factory and professional model company. You are in a better situation to find a proofing company that is more suitable. They survive by charging for proofing, and they will definitely accept your request for only two items.
2. The intention of the formal factory proofing is to have bulk orders, so of course I hope to return the order; the proofing company itself only makes prototypes or small batches, and he can't do it if you have a large order for him. 3. In terms of quality assurance, the regular factory is definitely better than the model company. The model company is a one-shot deal and the sample will be charged as soon as the sample is sent. There is no need to do the flying probe test. If the quality is not enough, you have to call it again. Money; regular factories usually do flying probe tests, from materials to craftsmanship with meticulous care and professionalism, so the quality often succeeds in one shot.
1. PCB proofing matters needing attention
As a collective of engineers, the precautions for PCB proofing are as follows:
1. Choose the number of proofs carefully to effectively control the cost.
2. Special recognition of equipment packaging to prevent proofing failure due to packaging errors.
3. Conduct a comprehensive electrical inspection to improve the electrical functions 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 as follows:
1. Check the PCB file materials carefully to prevent material problems.
2. Complete process approval and 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 accidents in advance.
2. PCB Proofing Market Distribution
The demand for PCB proofing is mainly gathered in areas where electronic products are more developed, such as Shenzhen, Beijing, smtsh.cn/target=_blank class=infotextkey> Shanghai, Suzhou, Hangzhou, Xi'an, Chengdu, Changsha and other cities.
The user group of PCB proofing is mainly electronic engineers, as well as student groups for academic research and research institutes.
Three. How to choose a suitable PCB proofing manufacturer
Mainly pay attention to several links:
1. Choose large companies and large enterprises, and the relative strength will be more secure, and the processing will be more regular.
2. Select the companies around Suzhou, the forefront of electronic products, complete supporting facilities to ensure delivery.
3. Choose a company with a good reputation, focus on service, and have a good cultural theme.
