Abstract:
An encapsulation method for a plurality of electronic devices within a mold cavity in an encapsulation device, said method comprising:providing a first substrate having a first side, a second side, and at least one electronic component on the first side of the first substrate;providing a second substrate having a first side, second side, and at least one electronic component on the first side of the first 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, said each mold cavity portion together comprising said mold cavity 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, 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, portions of said upper mating mold plate engaging portions of the first surface of said first substrate and portions of said lower moving of said upper and lower mating mold plates toward each other causing the second side of said first substrate and the 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; 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.
