CT8502
LT & RT & HT Die tester
Nexustest CT8502 is designed for laser chip LIV and spectral parameter test of bare die. The system integrates cassette loading (with grip rings), DUT ID recognition, transportation, temperature-controlled testing, automatic optical inspection, cassette unloading and sorting.
CT8502 has fast test speed, and can complete the whole process of DUT handling and testing under two temperatures within 4.5 seconds (under certain test plan). The system is very suitable for mass production. CT8502 is equipped with high accuracy linear motor, Oriental Motor step motor as well as high accuracy modules, which enables the system with precision and stability.
