PCB Metal and Component Placement
• Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing should
• Lead land length should be equal to maximum part lead length + 0.3 mm outboard extension + 0.05mm
• Center pad land length and width should be equal to maximum part pad length and width. However, the
• Four 0.3mm diameter vias shall be placed in the pad land spaced at 1.2mm, and connected to ground to
