Semiconductor Total Test Solution

The Best Partner, TSE!

"Delivering the promise of value-added innovation and technology to test."

TSE has been grown up with semiconductor industries since TSE was founded in 1994. TSE has developed test interface system, load board, test socket and probe card which are necessary for semiconductor test and has supplied to semiconductor chip makers worldwide.

Moreover, TSE has creates true value together with the customers by developing various types of TOB( Tester On Board) which improve the performance of existing ATE system. TSE operates MEMS production line, and produces wide range of products. the product items are MEMS Probe Card, MRC(MEMS Rubber
Socket), OLED MEMS Unit, MEMS Inductor, MEMS Relay, etc.

TSE supplies load board and test sockets required for SoC and Logic semiconductor devices, but also supplies handler equipment.
Based on those technologies, TSE contributes all our effort continuously to be a company to create new value consistently together with customers. We ask you a favor of your warm support and interest to TSE which makes a new take-off.
