| The CheckSum Model TR-9-2000-QC Long-Travel Pneumatic Fixture System is designed to be the basis for CheckSum stand-alone bed-of-nails test systems. Integrated into the system is rack space for system electronics, a keyboard, and a front panel with a minimum selection of buttons to make it easy, safe, and error-free for the operator to use.
The Model TR-9-2000-QC can be used for test fixturing of circuit boards up to 13.2" x 16". This fixture system can be used for most general-purpose bed-of-nails fixturing applications including those with top and bottom access, and TestJet Technology*. The Model TR-9-2000-QC utilizes a 6" long-travel mechanism so that a lid does not need to be opened and closed between tests. The unit-under-test (UUT) is simply removed and the next one put into place. To start the test, the operator uses both hands to press and hold the Test button in conjunction with a safety button. Once the test starts, the operator can release the buttons. For extra safety, a force-sensing mechanism causes the system to release if it encounters resistance during its downward travel until the last 0.5" of travel is reached. Change-Over for New UUTs With the integrated fixture interface, there are no cables to change or tools required. Fixtures can be changed out in a matter of seconds. Installing the new fixture is done by sliding the new cover plate and fixture base into position. Integrating System Electronics The Model TR-9-2000-QC can be used for most general-purpose fixturing applications, and can also be used when the unit-under-test (UUT) is difficult to gasket and seal on vacuum fixture systems: when probe loading per square inch is high, if many routed openings exist, or if there are open through-holes (often found on SMT UUTs). * TestJet Technology is protected under U.S. Patent Nos. 5,124,660 and 5,254,953. |
