摘要: A press comprises a frame made up of two crossheads rigidly interconnectedy means of uprights with two rams mounted therebetween one above the other. One of the rams has a built-in nut with a non-self-stopping thread to be thereby engaged with a screw rigidly connected to a die holder mounted for rotation in the other ram and geared to a drive for its translatory motion. Forced interaction between the nut and the screw is effected through a drive provided to actuate the ram with the nut and controlled from the drive of the die holder. There is provided a clearance of sufficient size between the rams to permit a specified angle of rotation of the die holder.

摘要: A method for assembling semiconductor packages (10) includes forming corresponding pairs of conductive pads (14, 16, 20, 22) on respective surfaces of a die (12) and an interconnective substrate (18). Each pad in each pair includes an upper portion comprising at least one component of an electrically conductive eutectic alloy. Sharp, upstanding peaks (50, 58) are formed on at least one of the pads in each pair. The die and substrate are forcefully abutted and the pads heated until the sharp peaks penetrate through oxide films (52) on the respective opposing pads in each pair and contact the upper surface of the other pad therein, thereby initiating pad fusion. The pads are then cooled to solidify the molten portions thereof into an electrically conductive joint between each corresponding pair of pads and a hermetic seal around the periphery of the package.
