Cookson Group Plaskon® SMT-B-1FX Molding Compound for PBGAs (discontinued **)
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Molding Compound
Material Notes:	This material is an epoxy molding compound optimized specifically for PBGA applications. It is a reduced catalyst version of SMT-B-1F and provides a 1-2% wire sweep improvement in most applications. It has the same unique resin system as the SMT-B-1, which minimizes warpage and enables trouble-free molding onto rigid and flexible laminate substrates. Minimal dimensional change after molding, post bake and subsequent solder treatment make this compound an excellent choice for PBGA applications. Features: Faster cure speed Improved wire sweep performance Improved warp performance High HSTL performance Lower viscosity Reduced cure time Information provided by Cookson Electronics
