What is the purpose of baking during PCB processing
Mar 20,2023
Why should PCB processing bake? Those engaged in PCB processing industry know that copper clad plate has a baking process in the process of processing into PCB circuit board, and the main purpose of PCB baking is to remove dampness Tide, remove the water gas contained or absorbed from the outside world, because some of the material used by PCB itself is easy to form water. Secondly, the purpose of...

What is the difference between four layers PCB boards and two layers boards？
Mar 29,2023
The four-layer PCB board is pressed on the basis of the double-sided PCB (two layer boards). Below is an outline that will help you understand and know the difference between 2 Layer printed circuit boards and 4 Layer printed circuit boards. 2 Layer Printed Circuit Board vs. 4 Layer Printed Circuit board In PCBs, layers are very important. Layers are copper layers on the circuit board. A circuit b...

Multi-layer PCB stack design
Apr 04,2023
Multilayer PCB or multilayer printed circuit boards are circuit boards composed of two or more conductive layers (copper layers). The copper layer is pressed together by the resin layer (prepreg). Due to the complexity of the multilayer PCB manufacturing process, low production volume, and difficulty in rework, their prices are relatively higher than a single layer and double-sided PCB. Multi-laye...

Why are most printed circuit boards green?
Apr 07,2023
If you are asked what colour a printed circuit board is, I believe the first response is green. Printed circuit boards are basically made up of pads, vias, solder resist layers, silkscreen layers, copper traces, various components and other parts. Copper is a more active metal, in the air is easy to react with the oxygen in the air, in order to prevent copper vaporisation, will use a special ink, ...
