Hello, Do you know if the 6X6mm version of the PIC16F18856 has a centre metal pad? The datasheet doesn’t say. The recommended land pattern (page 664) has a centre pad, and it is a potential short circuit hazard to the pin pads.......so we will not follow the recommended land pattern if the actual IC itself doesn’t have a metal centre pad.
