After the SMT processing is completed,the packaging needs to be inspected to ensure that the PCBA products delivered to the customer are working properly and reliably. ShenZhen PCBA processing manufacturer - Viasion Technology Co. Ltd will introduce the packaging inspection after SMT processing.

Does your printed circuit board have symptoms that are prone to heat? PCB board heat generation is a bad thing. We, PCB circuit board manufacturers, will focus on selecting raw materials to avoid these problems during production. Of course, the occurrence of heat generation problems is not necessarily the problem of PCB circuit board manufacturers, and It may be a problem with the customer's board design, let us talk about heat generation.

Soldering is a science. The principle is to heat and melt the solid solder wire with a heated soldering iron, and then make it flow between the metals to be welded with the help of flux, and form a firm and reliable solder joint after cooling.

The circuit board industry has windows in many manufacturing processes. It is a professional term for this industry, mainly referring to solder mask opening: using film to open the window, the PAD that needs to be soldered or dissipated is exposed to the green Outside the oil layer, in order to meet

At present, the market has higher and higher requirements for the anti-yellowing performance of the photosensitive solder mask white oil for printed circuit boards. Only by finding the cause of the yellowing of the photosensitive solder mask white oil can we find ways to reduce the yellowing condi

There are two common processes for printed circuit boards: tin spraying and tin sinking, both of which are surface treatment methods to meet the requirements of lead-free soldering. But in the circuit board process, tin sinking is not known to most people. The following editor will talk about the di

Immersion gold and spray tin are two common processes for circuit board surface treatment. What is the difference between these two processes? Which process is better? Most people are not very clear. Shenzhen VIASION Technology Co., Ltd. Just take everyone to learn about these two processes.

Treatment method of poor tin on circuit board:

The circuit board design and production process has as many as 20 processes. Poor tinning is really a headache. Poor tin on the circuit board may cause such as circuit sand holes, chipping, circuit dog teeth, open circuit, and circuit sand holes. Wire; if the hole is too thin, there will be no coppe

Circuit board brief For designers who are beginners to circuit boards, only after fully understanding the production process of circuit boards can they design circuit boards better. Therefore, it is necessary to have a certain understanding of circuit board production. The simple production process
