Disclosed is a load carrier for use with a test chamber. Such carrier includes (a) an insertion portion having a length about equal to the thickness of a chamber wall, (b) a carrier portion extending away from the chamber and (c) a flange interposed between the portions for sealing contact with the wall. The insertion portion extends through an opening in a chamber wall to connect to a rack holding printed circuit boards. The carrier portion holds a test device connected to the circuit boards through the load carrier. The load carrier is removable and can operate in 'standalone' fashion or be tested at a location remote from the chamber when another load carrier is substituted in the chamber. Chamber backplane wiring is eliminated or substantially eliminated.

Through-port load carrier and related test apparatus

A carrier for use in testing circuit boards includes a carrier frame adapted to be mounted vertically within a test chamber and a plurality of circuit board mounting modules for supporting at least one circuit board. The circuit board carrier frame has a plurality of vertically oriented module supports provided thereon and each of the circuit board mounting modules is constructed and arranged to be releasably mounted in one of the module supports. A first electrical connector assembly is mounted on the carrier frame for being connected to a source of electrical energy and test signals and a plurality of second electrical connector assemblies are each connected in circuit with the first electrical connector assembly and are located respectively adjacent the module supports and a third electrical connector assembly is mounted on each of the modules and each is adapted to be connected to one of the second electrical connector assemblies. A plurality of electrical contacts are located on the circuit board mounting modules for engaging individual portions of the circuit board to provide energy and control signals thereto and releasable retainers are pivotally mounted on each module for securing individual circuit boards in the module and in engagement with the electrical contacts.
