Lula, J W

Multilayer printed wiring boards (PWBs) were manufactured from a polyimide/glass reinforced copper-clad laminate and prepreg. A lamination cycle and innerlayer copper surface treatment were developed that gave satisfactory delamination resistance at soldering temperatures. When compared to similar epoxy/glass multilayer PWBs, the polyimide PWBs had higher thermal stability, greater resistance to raised lands, fewer plating voids, less outgassing, and adhesion that was equivalent to urethane foam encapsulants.
