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

inch

to 8

inch gold over 180inch nickel.

PCB Land Pattern Recommendation

PCB land patterns for RFMD components are based on IPC-7351 standards and RFMD empirical data. The pad pattern shown

has been developed and tested for optimized assembly at RFMD. The PCB land pattern has been developed to accommodate

lead and package tolerances. Since surface mount processes vary from company to company, careful process development is

recommended.
