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 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.

PCB Solder Mask Pattern

Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB

metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all pads. The

center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be

provided in the master data or requested from the PCB fabrication supplier.
