Abstract:
An encapsulation method for a plurality of electronic devices within a mold cavity in an encapsulation device comprising:providing a first substrate having a first side, a second side, and at least one electronic component on said first side of said first substrate: providing a second substrate having a first side, second side, and at least one electronic component on said first side of said second substrate; providing upper and lower mating mold plates, each mold plate of said upper and lower mating mold plates having a mold cavity portion, each said mold cavity portion of said upper and lower mating mold plates having a feed runner leading from a material supply to said each mold cavity portion and having a vent runner connected thereto for venting said each mold cavity portion, said each mold cavity portions together comprising said mold cavity portion of said encapsulation device; placing said first substrate having said at least one electronic component on said first side thereof and said second substrate having said at least one electronic component on said first side thereof into said mold cavity portion, said first substrate and said second substrate each having said second side thereof being located between said upper and lower mating mold plates; moving said upper and lower mating mold plates toward each other to form said mold cavity portion, portions of said upper mating mold plate engaging portions of said first surface of said first substrate and portions of said lower mating mold plate engaging portions of said first surface of said second substrate, said moving of said upper and lower mating mold plates toward each other causing said second side of said first substrate and said second side of said second substrate to have portions thereof in contact; injecting a first material into said upper mold cavity portion and a second material into said lower mold cavity portion to separately encapsulate said at least one electronic component on said first side of said first substrate and said at least one electronic component on said first side of said second substrate; and removing said first substrate and said second substrate from said upper and lower mating mold plates, said first substrate and said second substrate each having at least one encapsulated electronic component on said first side thereof.
