PCB Metal and Components Placement

The lead lands (the 11 IC pins) width should be equal to the nominal part lead width. The minimum

lead to lead spacing should be ≥ 0.2mm to minimize shorting.

Lead land length should be equal to the maximum part lead length + 0.3 mm outboard extension. The

outboard extension ensures a large and inspectable toe fillet.

The 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.
