A system for testing a device under test (DUT), in which electrical coupling among a module board, a low profile connector, and, a DIB is established by applying a pressure on the module board toward the DUT, is provided. The system includes a test head bracket secured inside a test head, the test head bracket includes the module board having a first section including a plurality of connectors to couple a test analyzer to the module board, a second section including a plurality of contacts pads to electrically couple the module board to the DUT, and, a flexible board to enable the first section to be placed at an angle with respect to the second section. The test head bracket also includes a module board stiffener mechanically securing the first section and the second section to the test head and the low profile connector electrically couples the module board to the DUT.

Apparatus for a low-cost semiconductor test interface system

An electronic circuit tester (e.g., for testing integrated circuit wafers or packaged integrated circuits) is provided. The tester is preferably based on a relatively inexpensive computer system such as a personal computer and includes at least one high-precision clock circuit that is programmable with respect to frequency and number of clock pulses. The high-precision clock circuit is connectable to the circuit being tested to permit certain timing-critical tests to be performed, even though a large number of other data channels in the tester are controlled by a relatively low speed clock circuit. The tester also includes analog circuitry that can be programmed to provide various analog signals suitable for performing parametric testing on an electronic device under test.
