Committed to ensure "Japan Quality" products to support customer's cost challenges.

UPT is the only photo etching company in Japan with overseas production lines in addition to domestic lines. From preproduction to volume production, let us help you to drive your innovation with our "Japan Quality" expertise with multi-lingual support.

Advanced high precision photo etching technologies for products of tomorrow.

"3D ETCHING", a technology to etch three dimensional metal object such as tubes and wires, is our unique photo etching technology. With this technology, we developed to etch magnesium tubes to make stents in medical use. In 2017, we established a new laboratory in Irvine, CA. to proceed further research and refine this technology.

To go beyond customers' expectation, we pursue our expertise to realize smaller, thinner and more precise products.

We continuously strive to realize customer's demands through technologies and solutions including diffusion bonding, thin metal plates post-precision etching, PI socket for semiconductor testing and others.
