What is a PCB green mask?

Time:2019-07-10 16:26:31 Click:

PCB green mask, a kind of solder ink that is called as solder mask in PCB. Solder mask is applied to circuits and substrates where PCBs do not need to be soldered, or just be used as a solder resist.

 

When it comes to the roles of solder mask, here are a couple of points for your reference:

 

1. Preventing short circuits caused by bridging in the welding technology;

2. Welding only in the positions where they must be welded;

3. Preventing insulation deterioration and corrosion caused by external environmental factors such as dust and moisture in order to protect the circuit for a long term;

4. With high insulativity, making the high density of the circuit possible.
