General Introduction of Multilayer PCB

As the name suggests, a multi-layer circuit board can only be called a multi-layer circuit board with more than two layers, such as four layers, six layers, eight layers, and so on. Of course, some designs are three-layer or five-layer circuit, also called multi-layer PCB circuit board.

Conductive wiring diagram larger than the two-layer board. The insulating substrate is separated between the layers. After each layer of the circuit is printed, each layer of the circuit is overlapped by pressing. After drilling, the electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board.

PCBA Testing Services

Our PCBA facility is equipped with state-of-the-art testing and validation equipment. Finished PCB components are checked for proper component placement and functionality through a variety of methods, including AOI inspection, in-circuit testing, and x-ray inspection.

PCBA SMT processing is very complicated and includes multiple important processes, such as PCB board manufacturing process, component procurement and inspection, SMT assembly, DIP, and PCBA testing. Among them, PCBA testing is the most critical quality control step in the entire PCBA processing process. The testing determines the final performance of the product.
