Peelable mask PCB: Peelable Solder Mask (also known as strippable mask or blue-mask) are applied by screen-printing, act as in-process protection and are removed after processing at the assembler. It provide the protection to keep solder flowing onto contacts, terminals and plated through holes (PTH) during soldering processes like wave soldering or reflow soldering.
