According to the layer number of PCB circuit board can be divided into single/double/four/six layer board and other multilayer circuit board, and can be referred to as the printed circuit board (hereinafter referred to as: "PCB"), as the carrier of electronic components, the design, manufacturing process and processing quality will directly affect the sales of the machine electrical performance, reliability, etc.,
The PCB directly affects the quality of the product quality,
In the process of our production, PCB has three important stages:
Abby circuit ipcb is: design, manufacturing, production and processing of
Design phase: PCB designer to complete the design drawings
Manufacturing stage; PCB supplier in accordance with the design data and requirements production PCB
Production and processing stages: product line complete, tend to have reflow soldering and wave soldering production line production line
Tell me the PCB board knowledge here
Say the first PCB plank classification:
1, according to enhance material points:
Base paper, glass cloth, composite base (CEM) and special materials (ceramics, metal core)
2, resin glue points:
Phenolic resin, epoxy resin, polyester resin, etc.
3, according to the structural strength points:
The copper-clad plate rigidity, flexible copper-clad plate
PCB diagram
Let's know the structure of the PCB
The thickness of the laminated structure associated:
Screen printing - green oil - copper - half cure - plate - half curing pills - copper - green oil - printing
Therefore I specially drew a PCB structure sketching to better illustrate:
PCB diagram
See the sketch, we learned a little PCB little knowledge, share here today, one day, we will become the industry's elite, don't give up, come on!
