Abstract : A pneumatic gross leak detector for testing micro-electronic packages. The apparatus includes a frame having a vertically movable upper section and a stationary lower section. A chamber is provided with walls which are secured to the upper section for movement therewith. The chamber includes upper, lower and intermediate portions disposed in communication. A test chamber base is secured to the lower stationary section to receive the microelectronic package therein. A first piston is provided in the upper chamber portion for moving the upper frame section downwardly for sealing engagement for the lower chamber portion with the test chamber base. A second piston is provided for compressing air in the lower chamber portion to a predetermined value. A readout device communicates into the test chamber to indicate if compressed air in the lower chamber leaks into the micro-electronic package. (Author)
