Abstract:
1. An apparatus for providing an encapsulation material to devices mounted on a substrate simultaneously, the apparatus comprising: two substrates, each having at least two electronic devices mounted on a first side thereof, having a thickness, and having an opposing back side having a planar surface having at least one of an array of conductive terminals and pads thereon; an upper mold plate and a mating lower mold plate, each upper and lower mold plate having a mold cavity portion, the mold cavity portion in each upper and lower mold plate together comprising a mold cavity for receiving a portion of the substrates, each portion of the substrates having the at least two electronic devices thereon for encapsulating the at least two electronic devices, portions of each substrate situated back side-to-back side in the mold cavity; a force-applying device for applying a force to the upper mold plate and the lower mold plate about portions of a substrate of the two substrates having an intervening first electronic device of the at least two electronic devices mounted thereon and the other substrate of the two substrates having an intervening second electronic device of the at least two electronic devices situated back side-to back side the mold cavity portion of the upper mold plate forming a first mold cavity over at least a portion of one of the first and second electronic devices and the mold cavity portion of the lower mold plate forming a second mold cavity over at least a portion of the other of the first electronic device and second electronic device of the at least two electronic devices; at least one passageway in each of the upper mold plate and the lower mold plate for separately introducing material into the first mold cavity and the second mold cavity to encapsulate one side of the first electronic device and the second electronic device of the at least two electronic devices; and at least one passageway connected to each of the first and second mold cavities for venting gases therefrom.
