United Precision Technologies Co.,Ltd.
The UPT group is one of Japan’s largest photoetching enterprise groups.
The current members of the UPT group are Kyosei Co., Ltd. and Koken Chemical Co., Ltd.
With relation to the semiconductor industry, we specialize in manufacturing jig trays, various probes and probe cards.
The UPT group, one of Japan’s largest chemical etching companies, specializes in precision machining of various metals using chemical etching.
UPT currently has two affiliates, Kyosei Co., Ltd. and Koken Chemical Co., Ltd.
In the field of semiconductors, the UPT group specializes in the following products:
1) Using diffusion bonding to process various jig trays, compared with other processes such as cutting, diffusion bonding offers no burr or deformation and higher precision with more complex shapes.
2) Using our etching process to create unique probes (patent pending). The traditional probes consist of 2 or 3 parts, however with UPT’s original design, the probe will be a single part providing advantages such as, lower cost, better conductivity and no arcing.
