Abstract: An article is formed according to a process including: (a) forming a substrate component including a thermoplastic composition; and (b) applying a laser activated plating (LAP) process to the substrate component to apply a metal film on the substrate component and form the article. The thermoplastic composition includes: (1) from about 10 wt % to about 80 wt % of a polycarbonate component; (2) from about 5 wt % to about 80 wt % of a siloxane component including a poly(carbonate-siloxane) copolymer or silicon oil, wherein the poly(carbonate-siloxane) copolymer, if present, is different from the polycarbonate component in element (1); (3) from about 10 wt % to about 60 wt % of a glass fiber component; and (4) from about 1 wt % to about 15 wt % of a flame retardant component including a phosphorous compound.
