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)

• A single 0.30mm diameter via shall be placed in the center of the pad land and connected to ground to

minimize the noise effect on the IC.
