PCB Metal and Components Placement
 The lead land width should be equal to the nominal part lead width. The minimum lead to lead spacing should be
≥ 0.2mm to minimize shorting.
 The 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.
 The 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).
 Two 0.30mm diameter via should be placed in the center of the pad land and connected to ground to minimize the
noise effect on the IC.
