UPT’s Photo Etching Technology Support the Hard-to-Process Materials, and Unique Shapes.

What’s Photo Etching Technology?

Photo etching technology is the process of using corrosive chemicals liquid to melt the specific areas on a metal sheet, and forms precise, unique and complex metal parts. This technology is able to form super fine shaping with high precision. Metal processed products need to be highly reliable because they need to maintain their performance over long periods of use and in harsh environments.
UPT offers “One-Stop Solution” of metal processed parts which support from prototype samples to mass production with short lead-time.

Benefits of Photo Etching Technology and Use-case

One of the major benefits of photo etching is that it processes metal without mechanical force, minimizing the risk of material deformation or damage. In addition, high precision processing is achieved by using photoresist to etch the specific area. Also, photo etching technology can be etched a wide range of materials, and it allows to maximize manufacturing flexibility and efficiency.
This technology is mainly used in the manufacturing equipment for electric components and semiconductors, such as jigs and small components which require extremely fine patterns and complex designs.

Applications of Photo Etching Technology

Semiconductor Test Solutions

Photo etching technology enables the processing of metals with excellent conductivity and durability with high dimensional accuracy. This strength is suitable for manufacturing probe pins and test sockets, which are key components in semiconductor test equipment. UPT offers the “Union Contact®” (one-piece probe pin) and “Micro Metal Socket®” (test socket).

Thermal Solutions

マイクロ流路構造のクーリングプレート

Photo etching technology has an excellent capability to form very fine flow paths used in thermal solutions such as cold/cooling plate and heat sink. This technology is suitable for applications which require high cooling performance to process complex patterns with high precision in metal sheets which have a high thermal conductivity. We offer thermal solutions for various types of cold/cooling plates and heat sinks.

Shims

Photo etching technology can process metal foils/plates and sheets with high precision, and it's an ideal solution for manufacturing gap adjustment components like shim spacers. This technology allows for consistent production of exact thickness and shape even with ultra-thin materials, making it valuable for applications requiring high accuracy.
