CheckSum TR-3-Console Vacuum Fixture System Overview

The CheckSum TR-3-Console Fixture System allows CheckSum Test Systems to be interfaced to the unit-under-test (UUT) via a Bed-of-Nails Vacuum/Mechanical Fixturing system.

The Model TR-3-Console Receiver Assembly accommodates up to 1500 test points and uses industry-standard GenRad 2270-compatible test head kits. All 1500 test point receiver pin-blocks and cables are included in receiver section. This eliminates the need to add any receiver parts in the future. CheckSum modules that are included in the shipment are pre-wired to the receiver. Additional modules can be added in the future and connected on-site to the available receiver pin-blocks.

The Receiver provides for connection of your vacuum pump via a 1-1/4"-hose connection.  The system has an automatic control valve that is remotely controlled by the test program.

Test heads can be obtained locally and customized for your specific application, or kits can be purchased directly from CheckSum. The Model TR-3-1620 is 16 x 20 inches (40.6 x 50.8 cm) and the Model TR-3-2024 is 20 x 24 inches (50.8 x 60.96 cm). For each 150 test points used for testing, a Model TR-3-2 Interface Block is required in the test head. CheckSum can also provide complete custom fixturing solutions or provide referrals.
