Abstract

Described is an advanced system used to control automatically the burn-in of printed circuit boards. Although most burn-in systems provide early life failure techniques, this advanced system is unique in that it utilizes the following features: 1. All testing is programmable utilizing the IBM Personal Computer and has the ability to test over 85% of all final test specifications. 2. Provides complete temperature cycling from -30ŒC to +125 C. 3. Up to 128 circuit boards are tested at one time through a unique drawer arrangement for reducing load/unload time to less than fifteen minutes. 4. Employs a wake-up system to assure all circuit boards meet the required specifications prior to the burn-in testing. 5. Provides complete voltage range testing. 6.

All testing is programmable utilizing the IBM Personal Computer and has the ability to test over 85% of all final test specifications. 2. Provides complete temperature cycling from -30OEC to +125 C. 3. Up to 128 circuit boards are tested at one time through a unique drawer arrangement for reducing load/unload time to less than fifteen minutes. 4. Employs a wake-up system to assure all circuit boards meet the required specifications prior to the burn-in testing. 5. Provides complete voltage range testing. 6. Controls temperature cycles, voltage cycles by an easily edited power/temperature profile. 7. Performs fault diagnostic routines. 8. Logs all data and statistics on each circuit board. 9. Alerts the operator to fuse-blown conditions. 10. Has the capability to down-load diagnostics for any special purpose testing or fault analysis. 11. The testing unit uses military specified components to assure long life. The system consists of a chamber, electronic interface/operators console, cart and wake-up station. The cart contains 64 slide-out drawers consisting of two interface boards containing all the electronics needed to communicate with the board under test. The board under test is m...
