How to choose a circuit board factory to buy a circuit board?
To buy a circuit board, the choice of a circuit board factory is the top priority. If you find an unreliable manufacturer and buy a circuit board with substandard quality, it will be a large loss to the enterprise. So how to choose the right one from many circuit board factories? It can be considered from the following three aspects:
1. The authenticity of the information
In most cases, the information we obtain from the circuit board factory is relatively mixed. Before making important purchases, we need to conduct in-depth investigations on key information, including at least the following points:
Qualification: It can be found through the professional qualification certificate verification website.
Credit and Registered Capital: The relevant registered capital and credit status can be viewed through the website of the Trade and Industry Bureau of the place of registration.
customer case: look for the cooperation customers advertised by the circuit board factory, and confirm the real situation of the manufacturer from them.
2. Manufacturer's Information
Under the premise that the above information is proved to be true, we must also consider whether the circuit board factory can provide stable supply and whether it is reliable. Regarding the reliability of the circuit board factory, the following studies can be conducted:
Registration Time: The average life expectancy of domestic small and medium-sized enterprises is only 2.5 years old, and that of group enterprises is only 7-8 years old, companies with less than 2 years of registration will have greater long-term cooperation risks.
Operating performance: The company's historical sales performance represents market recognition, and circuit board factories with good performance are usually more reliable.
Supply capacity: If the supply capacity of the circuit board factory is relatively weak relative to the sales situation, there may be untimely supply, which may lead to significant procurement risks. Therefore, when making a large number of purchases, the manufacturer's supply capacity must be checked.
Solvency: mainly examines the circuit board factory's ability to compensate for default to ensure that liability can be held in the event of risk.
3. Manufacturer's Service
Stability is also a guarantee for long-term purchase. Stability can be seen from after-sales guarantee. Good circuit board manufacturers usually make sufficient after-sales commitments in contracts, such as unconditional return of goods and free replacement of new products if there are problems.

Most electronic products are inseparable from the component is multilayer circuit board, and the production quality of multilayer circuit board factory directly determines the use of electronic equipment and the use of quality, there are many points in the circuit board processing related to the compatibility of multilayer circuit board, and then affect the quality of the circuit board. What are the main points of the compatibility design of multilayer circuit boards under the popular science?_multilayer circuit board_multilayer circuit board factory_blind buried hole circuit board_HDI board proofing

In the graphic electroplating process method of multi-layer circuit board factory, because the circuit pattern is easy to produce side etching in the etching process, the tin-lead alloy plating part is in the air and produces a suspension layer, which is easy to fall off, resulting in a short circuit caused by bridging between wires. Multilayer circuit board factory uses infrared hot melt process method, can make the exposed copper surface get very good protection. However, when it is used for infrared thermal melting of multi-layer circuit boards, the phenomenon of delamination and foaming between layers of multi-layer circuit boards is very serious due to high temperature, resulting in a very low yield of multi-layer circuit boards. _Blind buried hole circuit board_multilayer circuit board

Before designing multilayer circuit boards, the multilayer circuit board structure must be determined according to the circuit scale, circuit board size and electromagnetic compatibility (EMC) requirements. That is to decide whether to use a 4-layer, 6-layer or higher multilayer circuit board. Once the number of layers is determined, the multilayer circuit board factory has decided to determine the placement of the electrical layers in the multilayer circuit board and how to distribute different signals on these layers. This is the choice of multilayer circuit board factory laminated structure.
