PCB Metal and Components Placement
Lead lands (the 13 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 toe fillet that can be easily inspected.
Pad lands (the 4 big pads) 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, or
no less than 0.1mm for 1 oz. Copper, or no less than 0.23mm for 3 oz. Copper.
