Laser Diode Burn-in
BI6201
CoC Burn-in System
The BI6201 Burn-in System is a high-density, multi-functional testing system specifically designed for the verification of the burn-in lifespan of semiconductor laser chips. The system adopts a modular framework and a large single-layer structure, significantly reducing system costs by integrating multi-channel power supplies, temperature controllers, real-time data acquisition capabilities, as well as standardized drawers and flexible fixture configurations. Customized test fixtures are suitable for various packaging types of semiconductor lasers, such as CoC (Chip on Carrier),etc. of different sizes. The fixtures can be easily replaced to adapt with different types of devices. The driving circuit of BI6201 features excellent protection networks to prevent any current or voltage overshoot, eliminating potential EOS risks. It also allows setting thresholds for current and voltage, and the system can shut down abnormal channels when the output values exceed the threshold, providing enhanced protection for the tested chips. In addition to integrating protection functions into the control circuit, the system design also considers channel-to-channel isolation performance and electrostatic discharge (ESD) protection.
