IRDC3640
PCB Metal and Components 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).
Four 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.
