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 minimize 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)
? At least four 0.30mm diameter vias shall be placed in the center of the pad land and connected to
ground to reduce the routing lengths for all the components around the control 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.
