Preliminary Device Specification

AM7808

PCB and Stencil Drawing Design Requirements

PCB Surface Finish

Amalfi Semiconductor used an electroless nickel, immersion gold PCB finish in its qualification process. The typical

thickness is 0.076µm to 0.203µm gold over 4.572µm nickel.

PCB Land Pattern Recommendation

The PCB land patterns used for the AM7808 are based on the IPC-SM-782 standards. The patterns below have been

developed and tested for optimized assembly at Amalfi. However, each company has its own specific assembly

processes and requirements and therefore may require modifications to address these items. The PCB land patterns were

designed to accommodate for the LGA’s lead and package tolerances.
