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