Coplanarity includes exposed thermal pad and terminals
Reference land pattern layout (reference IPC7351
QFN50P400X400X80-25W6M)
All pads a minimum of 0.20 mm from all adjacent pads; adjust as necessary
to meet application process requirements and PCB layout tolerances; when
mounting on a multilayer PCB, thermal vias at the exposed thermal pad land
can improve thermal dissipation (reference EIA/JEDEC Standard JESD51-5)
