Burn-in testing of laser is an important method to ensure the reliability of laser. Through the test of CoC or bare die, the early failure of laser caused by the defects in the process of laser production can be screened out in advance. Semight provides a complete solution from bare die to CoC, from high temperature(150℃ or higher) to low temperature (-40℃), with CoC automatic loading and unloading system, forming a complete test solution, Semight's laser chip burn-in/load/unload test system has been widely recognized by the market.
Details
The semiconductor front-end test is mainly used in the wafer processing to check whether the processing parameters of the wafer products meet the design requirements or there are defects affecting the yield after each step of the manufacturing process. The semiconductor back-end test equipment is mainly used after wafer processing to check whether the performance of the chip meets the requirements, which belongs to the electrical performance test. Semight provides solutions such as Wafer Level Burn In system and Known Good Die handler for SiC testing, offering the value to customer in test efficiency improvement and test cost reduction.
