What United Precision Technologies Co. does

United Precision Technologies Co., Ltd. (UPT) is a Japanese B2B precision metal components manufacturer headquartered in Chiyoda-ku, Tokyo, that specializes in photo-etching (chemical etching of fine patterns on thin metal sheets) and diffusion bonding (atomic-level joining of metals below melting point to form internal 3D structures). The company's slogan — "smaller, thinner, and finer than anyone else" — captures its positioning around ultra-microfabrication, with stated capabilities including metal processing as thin as 0.004mm, ±10-15% tolerance of material thickness, 0.05mm minimum hole diameter, and micro-channels as narrow as 70μm. It holds ISO 9001 and ISO 14001 certifications and maintains inventory of approximately 500 material types to support rapid prototyping with lead times as short as two days. Two domestic subsidiaries (Kyosei Co., Ltd. and Koken Chemical Co., Ltd.) handle group-level HR and administrative functions. Representative Director Goto Hidehiro leads the company.

UPT's product portfolio spans custom contract manufacturing and proprietary branded components. Core proprietary brands include UHSS® (Union High Speed Sheet, an anisotropic conductive sheet supporting signals up to 100GHz/200Gbps for semiconductor testing), MMS® (Micro Metal Socket for IC final testing with one-piece structure supporting 67GHz), Union Contact™ probe pins, Union Tray® metal trays, Union Filter® ultra-fine mesh filters, Union Metal Mask™ SMT process masks, and VCM springs for smartphone camera optical image stabilization — the latter reportedly holding world top share. Thermal management products include cold plates (aluminum and copper), water-cooled heat sinks, semiconductor heat sinks, and backing plates. Custom shims, spacers, rings, base shims, and optical encoders serve precision machinery assembly. The company also produces fuel cell bipolar plates, electrostatic chuck heaters, polyimide heaters, lapping carriers, and semiconductor packaging LIDs.

UPT operates a sales-led B2B go-to-market targeting semiconductor and advanced electronics manufacturers across Japan, Taiwan, and broader Asia-Pacific (with Korean and Thai language support). Customer acquisition relies on industry trade shows (SEMICON TAIWAN, TECHNO-FRONTIER, Nepcon Japan, high-precision/difficult-processing technology exhibitions), direct website inquiries, private showroom visits, and technical content marketing through a blog, case studies, and YouTube product videos. Pricing is quote-based and not publicly disclosed. Primary customer segments are semiconductor industry and electronics manufacturing, with secondary exposure to automotive components, semiconductor manufacturing equipment, and medical device manufacturing. The company is privately held with no disclosed funding rounds, no parent company, and no public listing.
