Note:

A High-K board uses a thermal via design with the thermal landing soldered to the PCB ground plane with

0.3 mm (12 mil) diameter vias in a 3x3 matrix (9 total) at 0.5 mm (20 mil) pitch. The board is multilayer with

1-ounce internal power and ground planes and 2-ounce copper traces on top and bottom. A Low-K board

is a two-layer board without thermal via design with 2-ounce copper traces on the top and bottom.
