DS120904 RF6515 PCB Design Requirements PCB Surface Finish The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3inch to 8inch gold over 180inch 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. PCB Metal Land and Solder Mask Pattern Thermal vias for center slug “C” should be incorporated into the PCB design. The number and size of thermal vias will depend on the application, the power dissipation, and this electrical requirements. Example of the number and size of vias can be found on the RFMD evaluation board layout.
