Abstract:
A method for encapsulation of a plurality of electronic devices within a mold cavity, each electronic device having at least one electronic component mounted on a first side of a substrate, said method comprising:providing at least one electronic component on a first side of a first substrate, said first substrate having a first side and having a second side:providing at least one electronic component on a first side of a second substrate, said second substrate having said first side and having a second side;providing upper and lower mating mold plates, each mold plate of said upper and lower mold plates having a mold cavity portion, each said mold cavity portion of said upper and lower mold plates having a feed runner leading from a material supply to said mold cavity portion, said mold cavity portions together comprising said mold cavity;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, said first substrate and said second substrate each having said second side thereof being located between said upper and lower mold plates;moving said upper and lower mold plates toward each other to form said mold cavity, portions of said upper mold plate engaging portions of the first surface of said first substrate and portions of said lower mold plate engaging portions of the first surface of said second substrate;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 said at least one electronic component on said first side of said second substrate; andremoving 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.
