PCB Metal and Component Placement
• 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 0.3mm diameter vias shall be placed in the pad land spaced at 0.85mm, and connected to ground
be ≥ 0.2mm to minimize shorting.
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.
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)
to minimize the noise effect on the IC, and to transfer heat to the PCB
