thermal pad via
-"Via" type in thermal pad: Sometimes there is a single pin (for the symbol pin) and optionally multiple other vias for heatsinking, other times there are only vias. ,To dissipate this heat through the PCB, the exposed heat spreader is attached to a center pad with via holes. The center pad is surrounded by peripheral pads that ...
