In-Circuit Test Fixture Systems and Kits

CheckSum pneumatic and mechanical test fixtures are rugged, reliable and inexpensive-especially when compared to the heavy vacuum fixtures required by traditional in-circuit testers.

CheckSum fixturing is compatible with all of CheckSum’s test systems. Since the electronics are isolated from the fixture you can use CheckSum’s factory-built fixtures or build your own special fixturing or adapters that can accommodate ribbon-cable connectors.

CheckSum can provide fixture kits for your customization or do the complete fixturing and test programming job for you.

Available Fixturing Systems and Kits from CheckSum

Model TR-9-2000-TCE Long-Travel Pneumatic Fixture System

The CE Conformance tested TR-9-2000-TCE Long-Travel Pneumatic Fixture System which is integrated into a rack-cabinet is designed to be the basis for CheckSum stand-alone bed-of-nails test systems.  The long-travel press eliminates the need to open and close a lid between tests.
