摘要： A mechanical apparatus for testing a plethora of RF devices using test resources that are quickly and easily replaced is disclosed. The mechanical apparatus is located within an RF enclosure, and contains space for one or more test resources, or customizations, to be installed and applied to a device under test (DUT). The mechanical apparatus is coupled to the RF enclosure through a nest plate coupling to a drawer plate. This coupling is made into a tight seal through the use of o-ring elements that enables pneumatic pressure to be made available within the mechanical apparatus. The mechanical apparatus has a stationary base assembly, a lower nest assembly and an upper nest assembly. The DUT may be placed between the upper nest assembly and lower nest assembly, where the upper nest assembly and lower nest assembly may be coupled to test resources that may be applied to the DUT.

摘要： A system and method for radio frequency (RF) sealing a door of an RF enclosure is disclosed. The door employs a two-axis gimbal system to provide two degrees of freedom as the drawer door makes contact with the RF enclosure. The two-axis gimbal system allows the forces applied to the sealing gasket to be uniform along the length of the seal. This enables uniform seal compression, and therefore, uniform RF isolation. The door is held rigid while the door gasket is not affecting a seal against the frame of the RF enclosure. As the door becomes engaged with the frame, multiple contact points of the drawer door are deactivated thereby allowing the drawer door to pivot near the seal centroid on a two-axis gimbal system. The two-axis gimbal system allows the RF seal to be applied uniformly across the length of the seal.

摘要： The connector system for a printed circuit board test facility provides an efficient and unitary electrical and mechanical interconnection between the scanner pins of the bed of nails and the device scanner elecronics printed circuit cards that comprise the printed circuit board test facility. The connector system consists of a plurality of connector blocks oriented in a side by side arrangement to implement the xy coordinate axis matrix of scanner pins of the bed of nails. Each connector block consists of a custom molded plastic block that is equipped with replaceable spring loaded scanner pins. The connector block offers very high stiffness to minimize deflection under load of the spring loaded pins, very accurate dimensional stability, high impedance to electrical signals, a thermal expansion characteristic similar to the probe plate to which it is attached and very accurate positioning. Each scanner pin is connected t a lead wire that is bent in the shape of a question mark. Each lead wire passes through a corresponding plated hole in the device scanner electronics printed circuit card of the printed circuit board test facility and is soldered in place. The bend in the lead wires minimizes mechanical resistance to relative motion and also minimizes stress on the soldered connection and scanner pin caused by such motion. This connector system configuration provides a number of important characteristics: short electrical path from the scanner pins to the electronics on the device scanner electronics printed circuit cards; very accurate three axis location of each scanner pin with respect to a single fixed point in space; significant single axis compliance between the scanner pin and the device scanner electronics printed circuit cards to allow for scanner pin positioning when the device scanner electronics printed circuit card is fixed in that axis.
