A modular integrated pneumatic connection device adapted for precise location onto an upper platen accepts a printed circuit board (PCB) having the edge connectors thereof facing downwardly therefrom through a slot in that upper platen. The device includes pneumatically operated and spring loaded pistons at opposite ends thereof which interact with a bracket holding the PCB, such that upon placing that upper platen above a lower platen having disposed thereon a test board or the like including printed circuit board connectors that are in alignment with those PCBS, application of pneumatic pressure forces the edge connectors of those PCBs in the upper platen into the PCB connectors disposed on the test board or the like on the lower platen, thereby making electrical contact for testing and similar purposes, i.e., as a "Unit Under Test" (UUT). Upon release of the pneumatic pressure, the PCB is withdrawn from that connection by operation of the above-mentioned springs. Since the pneumatically operated pistons are integrated within the device module, that module can be made in a sufficiently narrow dimension (e.g., 0.790 in.) to permit use of an array of the same in connection with the standard inter-connector layout dimension (e.g., 0.800 in.) of PCB connectors or the like on test boards, motherboards and the like. Upon appropriate changes in dimensions, the device is also applicable for the testing of central processing units (CPUs) or other electronic components, or alternatively for the application of arrays of one or more test probes onto a mother board or the like (which would then become the "UUT"), and with respect to PCBs, CPUs or any other type of UUT, the module presents the advantage that each such UUT may be individually connected and disconnected.

[ I claim:] [1.]1. An apparatus for removably and individually placing one or more electronic devices having an array of first connectors disposed on a first side thereof, mutually parallel holding strips at opposite ends of a second side thereof that is normal to said first side, and grasping stubs coplanar with said second side and extending outwardly from opposite ends thereof, into electronic connection through said first connectors with corresponding arrays of second connectors that are mounted in dispositions corresponding to those of said first connectors on a circuit board, comprising:one or more box-like bodies;a plate-like frame including one or more slots passing therethrough;attachment means for removably attaching selected ones of said one more bodies to said plate-like frame, at locations that will encompassing within the dimensions of each of said one or more bodies particular ones of said one or more slots;an aperture extending through each of said one or more bodies;movable means disposed within each of said apertures for grasping said electronic devices in a disposition such that said first connectors are oriented outwardly, whereby, upon placement of said electronic devices within said movable means and attachment of said one or more bodies to said frame, movement of said movable means as to selected ones of said or more bodies causing said first connectors of said electronic devices contained within those selected ones of said one or more bodies to move into and out of those particular ones of said one or more slots that are encompassed within the dimensions of said one or more bodies by said attachment.
