PCB Solder Mask Pattern
Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the
PCB metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all
pads. The center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask
clearance can be provided in the master data or requested from the PCB fabrication supplier.
