Peel Mask PCB
Peel able masks are used in order to protect selected solder holes against plugging during mass soldering or to protect carbon elements and gold plated contacts during mass soldering. Peel able masks are screen printed.

Requirements
• The peelable mask must adhere sufficiently well to the PCB so that it does not peel off when handled correctly.
• It must be able to endure a two to three time soldering process without peeling off, but must remain detachable.
•After soldering of the PCB, the peelable mask must be able to be detached – preferably in one piece. In case of metallized holes, no mask
residue must be left in the drill holes or on the surface of the PCB. In the case of non-metallized drill holes, however a certain amount of residue
can remain.
• The peelable mask must be able to resist conventional solvents such as chlorinated and fluorinated hydrocarbons, isopropanol, conventional
fluxes and similar.
• Particular requirements: The roughness U of the edge of the mask can be 0,5 mm from the tip to the base (left figure
below).
