New Equipment | Solder Materials
A variety of printed circuit boards require protection of selected board areas during the Surface Finish or Assembly Process. A wide range of PEELABLE SOLDER MASKS, the SD 295X Series including the popular SD 2954 and SD 2955 provide such protection

Just curious...What is the gap between the pads? If it's less than 3 mm, it's recommended to do gang relief. Otherwise the soldermask will peel off during rework.

Hi its undercured solder resist which leaves a clear waxy/oily residue and can be seen as brown tar/oil in the molten solder wave. This also causes MicroSolder Balling and some snail trails of solder pick up and worst case bridging and peeling resist
