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 8µinch 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 processes. The PCB land pattern has been developed to accommodate lead and package tolerances.
