The clamping stage may be mounted directly to the base of a testing machine in order to provide accurate adjustment and indexing of the specimen position during testing. In a typical test configuration the assembly under test would be mounted in the PCB clamping stage fitted to an X-Y translation stage or directly to the base of a test machine and a lead pull grip would be mounted below the load cell on the moving crosshead or actuator.

The Theta-X-Y manual translation stage provides the facility to precisely position and align a test specimen below the actuator (two axes). Theta (angle) and X-Y axes are also adjustable via digital micrometers. The rotary axis can be adjusted via a micrometer and has a vernier scale readable to 5 ft. The X-Y axes micrometers have a resolution of 1 micron. The axes are arranged with the angle stage at the base, with the X-Y stage on top. This allows the test platform to be oriented with the X-Y axes referenced to the specimen. Typical applications include lead pull and component pull off tests on microelectronic devices and PCB’s.
