BI6202
CoC Burn-In System
The BI6202 series 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. Integrated multi-channel power supplies, temperature controllers, real-time data acquisition capabilities. Standardized drawers and flexible fixture are suitable for various size of CoC (Chip on Carrier). The fixtures can be easily replaced to accommodate different device types. Drawers could be replaced when new test functions are added, such as thermistor monitoring, power monitoring.
- Driving power supply – Support up to 8448 channels standard power supply
- Strong thermal conductivity – Temperature deviation ＜ ±1.0℃ for the overall thermal sink（40～100℃）
- Temperature control – Each fixture has independent heating, temperature control, monitoring, over temperature protection and heat dissipation units for energy saving.
- Fixture – Fishbone-type fixture which support wire bonding on it.
- Safety and reliability – Comprehensive protection mechanisms through hardware and software eliminate potential issues such as EOS.
- Online power monitoring –Optional configuration for online power monitoring, supporting complete LIV or EA scans, with the ability to analyze Ith. The test repeatability deviation ＜±1%.
- 4224 CoC simultaneously burn-in – Production capacity flexibly configured based on customer requirements.
- Software functions – All test results, test statuses, and abnormal conditions are recorded in the database which could be stored and traced efficiently.
