Jupiter Test Fixture

Mechanical Fixture for Functional Test

Columbia's Jupiter Mechanical Press is designed to provide precise, bed-of-nails contact, in a production test environment. Durable aluminum and steel construction and precision bearings insure accuracy and repeatability sufficient to contact test points as close as 10-mils center-to-center.

The unit can be configured to provide simultaneous contact to both the top and bottom sides of printed circuit boards or other substrates. The cost of probe plates and pusher plates is significantly lower than the cost of comparable vacuum fixturing and the press can be easily reconfigured for different UUT part numbers.
