Abstract
A system is provided which allows for burn-in testing of electronic devices wherein power current is provided individually to each one of the electronic devices. The system also includes various connectors, cables, and other configurations that allow for power currents having large magnitudes to be provided to the electronic devices.
Claims18
A driver assembly, comprising:
- a driver substrate;
- a plurality of driver signal connectors secured to the driver substrate, each driver signal connector having a surface for releasably mating with a respective signal contact and each driver signal connector to carry a maximum direct current having a first magnitude;
- signal electronics connected to the driver signal connectors;
- a plurality of driver power connectors secured to the driver substrate, each driver power connector having a surface for releasably mating with a respective power contact and each driver power connector to carry a maximum direct current having a second magnitude which is larger than the first magnitude;
- and
- a single power supply connected to the driver power connectors.
