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.
