PCB METAL AND COMPONENT PLACEMENT
? Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing should
be ≥ 0.2mm to prevent shorting.
? Lead land length should be equal to maximum part lead length + 0.3 mm outboard extension + 0.05mm
inboard extension. The outboard extension ensures a large and inspectable toe fillet, and the inboard
extension will accommodate any part misalignment and ensure a fillet.
? Center pad land length and width should be equal to maximum part pad length and width. However, the
minimum metal to metal spacing should be ≥ 0.17mm for 2 oz. Copper ( ≥ 0.1mm for 1 oz. Copper and ≥
0.23mm for 3 oz. Copper)
? Four 0.30mm diameter vias shall be placed in the center of the pad land and connected to ground to
minimize the noise effect on the IC.
? No pcb traces should be routed nor vias placed under any of the 4 corners of the IC package. Doing so
can cause the IC to rise up from the pcb resulting in poor solder joints to the IC leads.
