PCB solder mask ink

PCB solder resist ink is mainly used in circuit board, also called PCB inks, prevent short circuit caused by soldering pulling, at the same time it also has excellent Electrical Performance, Chemical performance. Moisture proof, mould proof, salt fog resistance.

PCB solder mask ink main functions are as follows:

（1）Prevent physical disconnection of the circuit conductors；

（2）Welding process, to prevent short circuit because of the bridging；

（3）Only in part must be welding welding, to avoid solder waste；

（4）Reduce copper pollution of welding groove；

（5）To prevent from dust, moisture and other external environment factors causing deterioration of insulation, corrosion；

（6）High insulation, made it possible to high density change of the circuit。
