For a SPRINT test jig, the test fixture "cradle" is specific to the Device Under Test (DUT). The cradle consists of:
A main plate, which supports the test pins
A cover plate, with holes for the test pins, and alignment and support pins for the DUT. A spring-loaded support system holds the cover plate up, so that the test pins are protected when the jig is not closed.
A Test Interface Board (TIB), to which the test pins are soldered. Typically, the TIB simply connects the test pins to a back edge connector; but it may also include test circuitry.
By default, a SPRINT test jig supports only test pins on one side of the DUT. For applications which require test pins on both sides of the board, contact Elprint to discuss the possibilities with a test systems engineer.
SPRINT test fixtures support P100/R100 (2.54mm pitch) and PL75/RL75 (1.91mm pitch) pins and receptacles. When defining test points, the desired pin head style must be specified. It is also necessary to specify suitable locations for guide/support pins.
Use the Gerber or DXF button to generate a Gerber or DXF file of the test circuitry PCB outline and pin locations, for import to your CAD system.
