PCB Circuit Inks
PCB Circuit ink is used as the barrier layer of the anti-corrosion line to protect the line during etching. Generally, it is a liquid photosensitive type. There are two types of acid corrosion resistance and alkaline corrosion resistance. This layer of ink needs to be dissolved with alkali after corroding the circuit.
