Located in Changzhou, Ketai Guangxin (Changzhou) Testing Technology Co., Ltd. was established in 2019. It specializes in the R&D, production, sales, and service of optoelectronic semiconductor device testing equipment. The company is committed to helping customers accelerate the construction of a pathway from R&D testing and sampling, through small-batch testing, to large-scale mass production testing, while providing users with diversified testing products and solutions. Today, the growing Ketai Guangxin has become a relatively comprehensive optoelectronic semiconductor testing equipment and service provider in China. It helps address the “bottleneck” problem in testing equipment within the production processes of optoelectronic semiconductor devices, and has also become a testing partner for several leading domestic LiDAR companies.
