Patent ID: 8330482

Claim:
A test system for testing electronic devices each one having a case with a plurality of terminals, the test system including: a set of test boards, wherein each test board includes a plurality of banks of electrically conductive receptacles each one for resting a corresponding electronic device, each receptacle being adapted to receive a terminal of the corresponding electronic device, a loader/unloader for releasing each electronic device with the terminals facing downwards on the corresponding bank of receptacles, the electronic device freely resting on the bank of receptacles without any mechanical lock, a set of boxes arranged in operation above the test boards to define a set of corresponding expandable chambers for a conditioning fluid, each box including a rigid body, a flexible membrane of a thermally conductive material facing the test boards, an inlet, and an outlet, means for controlling a temperature of the conditioning fluid, and means for forcing the conditioning fluid to circulate under pressure through the chambers to expand the flexible membranes downwardly, the expanded flexible membranes pressing the electronic devices freely resting on the corresponding banks of receptacles against the test boards to lock the electronic devices mechanically on the test boards and to condition the electronic devices thermally.
