Thermal Test Fixture for        
Burn-in & Life-test        

Burn-In and Life-Test of electronic devices require the implementation
of both electrical and thermal stress.

iTest offers test fixtures designed for each way of managing the thermal stress:
Oven fitted with airproof crossing for Burn-In / Life-Test applications

  • Fitting out an oven for a set of Burn-In Boards.
At the oven's rear panel, each slot is fitted with an airproof crossing and an external backplane board. A large temperature range can be endured with dedicated printed circuits, while keeping safe standard range external connectors and cables.
The common ambient temperature and/or the actual device's package temperatures will be monitored by Bilt thermocouple input module (BE426,427).

  • Heating / cooling plate for controlling a limited area within a test fixture:
When the tested components are fitted with a conductive bottom side, the control of a base plate's temperature is faster, more accurate and more efficient than using an oven. In addition, close to the small hot area, the burn-In board can gather active drivers, connectors and cables performing standard temperature range.
Different test fixtures are developed to fit the component's footprint, the temperature and the dissipated power requirements:
