Residue Removal (Descum)

Plasma treatment removes resist residue from PCB inner layers and panels without affecting the circuit pattern. It also removes residual solder mask bleed from lands for better bonding and solderability.

Resist residue sometimes remains after developing fine pitch circuitry. If the residue is not removed prior to etch, the board can short circuit. Plasma effectively removes resist residue from inner layers and panels without affecting the circuit pattern. It also removes residual solder mask bleed from lands for better bonding and solderability.
