Attachment 4 Exhibit 6.3 PAM CCA Assembly Drawing and Schematic .pdf

This document is a technical drawing and assembly specification for a Serialized Assembly circuit card power module manufactured by Westinghouse Electric Corporation. The document contains detailed mechanical drawings, electrical schematics, and assembly instructions presented across multiple pages with various cross-sectional views and component specifications.

The assembly specifications include requirements for fabrication and processing of the circuit card, with detailed notes on hole placement, layer construction, conductor requirements, and surface treatments. Key specifications include: all holes located from intersection of locating base lines; all layers viewable through layer including the drill and trim view; workmanship per established standards; plate all exposed aluminum with not less than 250 microinches of nickel per specification; 250 microinches of matte tin plating per chromate requirement; registration holes used as required; circuitry surface specifications; and tolerance applications with surface restraints. The document references a separate parts list and indicates this is a computer-generated document with manual changes not allowed. Multiple assembly views, electrical schematics, layer diagrams, and drilling specifications are provided to support manufacturing and assembly operations for this power module component.
