Fast prototype pcbs are widely used. Most of the PCB we see is green. Why is that?

1, green solder resist printing ink is the oldest, and the cheapest and most popular.

2, in general, the entire electronic board level products have to pass the system board and post process, in the process of making the board, there are several processes to go through the yellow light room, green in the yellow room visual effects better.

3, there is a common red yellow green blue black.

4, blue and black because they are doped with cobalt and carbon, has a certain conductivity, so there is a risk of short-circuit, green PCB more environmentally friendly, high temperature environment will not release toxic gases.

We can supply the high quality pcb, gold plated pcb etc. If you need, welcome to contact us.
