United Precision Technologies Co., Ltd. (UPT) is an ultra-precision metal processing manufacturer that leverages photo-etching and diffusion-bonding technologies to achieve products that are “smaller, thinner, and finer than anywhere else.” With strengths in micro- and precision forming, the company develops and mass-produces a wide range of high value-added products, including VCM springs for OIS (optical image stabilization) in smartphone cameras, semiconductor test sockets/contact components, precision shims and spacers, microchannel cooling parts, and process jigs and trays.

Main Products

・Cold Plate
A cooling device used for heat dissipation in electronic equipment and semiconductor devices, featuring channels inside through which coolant flows.

・VCM Spring
Springs for optical image stabilization systems (OIS) used in cameras of high-performance smartphones.

・Shims / Spacers
Shims and spacers that enable adjustment of tolerances and accumulated errors generated during precision machine assembly, such as semiconductor manufacturing equipment.

・Process Jigs / Trays
High-precision metal trays that integrate the functions required for electronic component manufacturing processes into the jig design.

・Micro-Fine Mesh Filter
Ultra-fine metal mesh filters created through “photo-etching + diffusion bonding.”

Semiconductor Test Solutions

・Test Socket MMS
A test socket designed to accommodate the miniaturization and fine-pitch requirements of next-generation semiconductors.

・Anisotropic Conductive Sheet UHSS® (Union High Speed Sheet)
With high design flexibility and excellent high-speed signal characteristics, it improves semiconductor test efficiency and enables higher performance in electronic devices.
