 Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing should
 Lead land length should be equal to maximum part lead length + 0.3 mm outboard extension + 0.05mm
 Center pad land length and width should be equal to maximum part pad length and width. However, the
 Four 0.30mm diameter vias shall be placed in the center of the pad land and connected to ground to
 No pcb traces should be routed nor vias placed under any of the 4 corners of the IC package. Doing so
