Upgrade Retrofit for Testronics Model 401 - Backplane / Backpanel Tester


The upgrade retrofit is performed on-site with your Testronics Model 401 system, world-wide:
  • Replaces the Testronics electronics and press controls with CheckSum test electronics
  • Worldwide support for the complete tester – electronics and Testronics press unit
  • Full mechanical/electrical service contracts are available for on-site support
  • New "Fixture Lock-down" capability to verify contact between the fixture interface and the test probes. This fixture lock-down mechanism provides two superior features:
    1. Reduces wear of the spring-probes and fixture target pads since the fixture would only move down and up once, when a new fixture is installed and removed. The present system actuates the system spring-probes for each UUT tested. Spring-probe fatigue and target pad deterioration will cause intermittent connections and unreliable test program results.
    2. The fixture spring-probe pins can be probed for connection to the test system electronics with the CheckSum single-point probe after the lock-down is engaged, the press unit top is disengaged and the fixture lid is opened. This allows verification of proper connection between the fixture and the system. Test probe connection to the UUT nets is also possible if the UUT can be held down in contact with the fixture spring-probes.
  • Modern ICT system with on-going development path
  • Extensible architecture
  • Additional functional and on-board part programming (ISP) capabilities
  • Program converter for existing Testronics programs
  • Continue to use Testronics press and fixtures
