TO Three-temperature Automatic Test System


PSS TO three-temperature test system supports industrial-grade low temperature, normal temperature, high temperature test of TO-CAN, the temperature control range is -40°C ~ 85°C, suitable for VCSEL/FP/DFB TO-CAN automatic testing, support arbitrary pin package test of the device, support LIV characteristic test and spectrum test. The system supports two fixtures for testing at a time, each fixture can be loaded with 128 TOs, which improves the test efficiency. The system has the advantages of fast temperature control, good temperature uniformity, stability and reliability, and high test efficiency.
