PCB Metal and Components Placement
Lead lands (the 11 IC pins) 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. The
outboard extension ensures a large and inspectable toe fillet.
Pad lands (the 4 big pads other than the 11 IC pins) length and width should be equal to maximum
part pad length and width. However, the minimum metal to metal spacing should be no less than
0.17mm for 2 oz. Copper; no less than 0.1mm for 1 oz. Copper and no less than 0.23mm for 3 oz.
Copper.
