Peelable solder mask
Peelable solder mask protects selective areas on printed circuit boards which go over the solder wave (wave soldering / flow soldering) several times. In order to prevent the wetting of some areas with tin, a peelable soldermask is applied by the PCB manufacturer. In a subsequent soldering process, where these areas are to be soldered, the peelable solder mask can easily be pulled down.
For orders, please tell us always the used layer for the peelable solder mask as well as the side (TOP / BOTTOM) to apply it.
