/Why should PCB circuit boards be painted with three anti lacquer?
In the electronic processing this one in the industry have a quality control key points can not be attention to directly, it is that we have pcba anti-corrosion paint link, although the relative materials, SMT, plug-in processing, may not have been frequently mentioned to, but for every little detail plays an important influence in SMT processing, don’t lose any details as we look at the attitude of quality, more is we treat each customer a basic principle.
Three anti – paint effect
Route of PCB board in the electronics, medical, smart home, car, etc will be applied to the industry, according to the course plate used, in order to extend the service life of the line board, protect pcba has reliable performance, we will do some daily protection treatment, such as pcba in the process of PCB in SMT processing coated with paint.Here’s a look at the role and benefits of PCBa anti-paint:
1. The appearance improvement of pcba circuit board, whether transparent or with color protective paint, can improve the appearance of printed route board, while the latter can guarantee a higher degree of confidentiality by covering the component design layout.
What is the reason for PCB routing board to use anti-paint?
Avoid oxidation.The PCB route board is coated with anti-paint to protect the tin spots on the outside of the pcba circuit board from being oxidized by the air, which can look more beautiful, avoid dust obstacles and affect the normal operation of the route board.
3. Reduce the occurrence of PCB fault in SMT patch processing.The PCB routing board can be applied with anti-paint to avoid the occurrence of some other problems, such as insulation between the tin feet of PCB circuit boards, anti-static, short circuit and so on.

4. Extend the service life of the circuit board.The PCB routing board can be coated with anti-paint to form the protection capacity on the outside of the PCB, which can effectively prevent dampness, insulation and static electricity, etc., and can ensure the circuit board to operate normally in a poor environment and delay the service life of the circuit board.
PCB circuit board with anti-paint can make the product more stable, durable and beautiful, which is an important protection measure in the process of PCB production.
① Prepare a actual product surface soldered pcb assembly board . Because printed solder paste and the PCB assembly board without soldering cannot fix the test end of the thermocouple, it is necessary to use the soldered actual product for testing. In addition, the test sample cannot be used repea...
Most military industrial enterprises in China use epoxy insulation varnish as a three-anticoating material, using traditional immersion, brushing and spraying processes. Because the output of military products is relatively small, many companies use manual operations. The main disadvantage of man...
Pcb prototypes samples need to be aged prior to solderability testing. Because the solderable surface of the component or PCB circuit board that has just been produced is generally not problematic, it will deteriorate due to oxidation after being stored for a period of time. The test must conside...
