How to clean PCB

Dust the circuit board.

The electrolytic capacitor capacity of the circuit board for sampling inspection, such as found that the electrolytic capacitor capacity is less than 20% of the nominal capacity, should be replaced, the life of the general electrolytic capacitor about 10 years should be replaced, to ensure the performance of the circuit board.

Proofing those unknown high multilayer circuit board PCB production difficulty

As the "core main force" of multilayer PCB in communication, medical treatment, industrial control, security, automobile, electric power, aviation, military industry, computer peripheral and other fields, the product functions are getting higher and higher, and the PCB is getting more and more precise, so it is more and more difficult to produce.

Proofing those unknown high multilayer circuit board PCB production difficulty

Why do we always insist on "100% full test" for PCB production?

PCBQuick does not have the option of "random test", PCBQuick defaults to "100% full test", to ensure the high quality of each board, quality is the survival of the enterprise.

PCB Surface Finish Options Or Types

The basic purpose of PCB surface treatment is to ensure good weldability or electrical properties. Due to copper easily oxidized in the air, copper oxide layer on the welding has a great influence, it is easy to form false welding, welding, caused serious welding plate and components cannot be welded, as such, PCB in production, there will be a process, in the welding plate surface coating (plating) after a layer of material on, protect welding plate from oxidation.
