Pcb Manufacturing Companies

At present, many manufacturers use another method of wiring, which is to connect some of the lines, and it uses buried and blind hole technology in the wiring. Blind hole is a few layers of internal PCB and surface PCB connection; it does not penetrate the entire circuit board.

PCB Knowledge:

On the basic single layer PCB, the components are concentrated on one side and the circuits on the other. If multilayer board is to be used, the board needs to be perforated so that the components pin can pass through the board to the other side, so the guide hole will go through the PCB board. So we can see that the pin of the part is soldered on the other side.

At present, many manufacturers use another method of tracing, which is to connect some of the circuits, and it uses buried and blind via technology in the tracing. Blind via is a few layers of internal PCB connect the surface PCB; it does not penetrate the entire circuit board.

The buried via is only connected to the internal PCB, so it is not visible from the surface. Because the blind via does not need to penetrate the whole PCB, if it is six or more layers, the light will not pass through the card against the light source. So there was a very popular saying:to determine four layers and six layers or more of PCB by seeing if the through holes leaking light.This method has its own reason, and it also is not suitable, it may use as a kind of reference method.(pcb manufacturing companies)
