Abstract: A press pad for bonding substrates into a radio-frequency and/or intermediate-frequency module. The module has a plurality of channels, each of which has an adhesive film for bonding the substrate. The press pad has a pad body conformal to the substrate and pairs of lateral protrusions extending from central axes of opposing surfaces of the pad body. The protrusions are in the forms of semicircular bumps or fins extending perpendicular to the opposing surfaces. Therefore, the lateral extent of the press pad within the channel is minimized, such that the misalignment and inclination of the press pad is minimized. Further, the lateral protrusions are fabricated from material operative to resist lateral pressure, such that deformation of the press pad caused by lateral pressure is also prevented. Therefore, pressure gradient and pressure loss are prevented.

Abstract: A method for plating a graphite aluminum metal matrix composite material with nickel and gold utilizes the steps of: cleaning a surface of the metal matrix composite material so as to substantially remove grease and particulates therefrom; forming a layer of copper upon the surface of the metal matrix composite material; heating the copper layer to drive out entrapped fluids; applying acid to the copper layer to remove oxidation therefrom; forming a layer of nickel upon at least a portion of the layer of copper; heating the nickel layer to relieve stress therein; and electrolytically forming a layer of gold upon at least a portion of the layer of nickel.
