PCB Design Requirements

PCB Surface Finish

The PCB surface finish used for RFMD’s qualification process is Electroless Nickel, immersion Gold. Typical thickness is 3

μinch

to 8

μinch Gold over 180μinch Nickel.

PCB Land Pattern Recommendation

PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and tested

for optimized assembly at RFMD; however, it may require some modifications to address company specific assembly pro-

cesses. The PCB land pattern has been developed to accommodate lead and package tolerances.
