Low Power TO Integrated Burn-in System


PSS LD integrated reliability system is used for burn-in screening and reliability and life analysis of low-power visible light LD TO devices, which effectively improves the quality of TO products after screening. The system can support the burn-in of 3072 devices, and realize the burn-in of devices by providing constant current to LD devices. The system can display the burn-in current, direct voltage, backlight current, temperature, power and other parameters in real time and display them visually, which is convenient for observing the abnormal situation in the burn-in process. The universal burn-in board is compatible with other automation equipment of our company.

    Product Application

    • It can be used for burn-in screening of visible light LD TO devices in mass production.
    • Analysis of long-term reliability failure test

     

     

     

  • Product Features

    • Provide completely independent driving current for each burn-in board.
    • The integrated burn-in box comes with two independent boxes, which can be completely controlled independently, with high heating speed and no overshoot; Support over-temperature protection
    • ACC constant current mode and APC constant backlight mode are optional.
    • As a general carrier, burn-in board can realize direct material transfer at different stations of disk testing and burn-in, and improve production efficiency; An NTC thermistor is installed next to each TO56 slot to detect the temperature in real time.

     

     

    • Each burn-in board can be equipped with a pre-installation optical detection board to monitor the optical power before burn-in in real time and test the LIV characteristics regularly.

     

     

    • Reliable ESD/EOS protection ensures the safety of devices during burn-in and supports open circuit and short circuit protection.

     

     

    • Support scanning LIV to calculate Ith

     

     

    • Software switching supports burn-in of various types of packaged LD devices, and supports TO56 fixed 3-pin switching.
