PCB METAL AND COMPONENT PLACEMENT
• Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing should be ≥
• Lead land length should be equal to maximum part lead length + 0.3 mm outboard extension + 0.05mm inboard
• Center pad land length and width should be equal to maximum part pad length and width. However, the minimum
• Four 0.3mm diameter vias shall be placed in the pad land spaced at 1.2mm, and connected to ground to minimize
• No PCB traces should be routed nor vias placed under any of the 4 corners of the IC package. Doing so can cause
0.2mm to minimize shorting.
extension. The outboard extension ensures a large and inspectable toe fillet, and the inboard extension will
accommodate any part misalignment and ensure a fillet.
