Surface treatment to prevent surface cracking due to thermal history in semiconductor devices and automotive parts.
"No cracks occur even at 200℃" "Contributes to improved yield and reduced frequency of part replacements!" *Catalog with case studies available.
"WELMITE" refers to our in-house developed heat-resistant anodizing treatment (anodic oxidation treatment of aluminum components). Typical anodized coatings can develop cracks due to differences in thermal expansion coefficients between the anodized layer and the aluminum substrate. This coating structure aims to alleviate the differences in thermal expansion, and no cracks occur even in a 200°C cycle test. In applications where components such as semiconductor device parts or automotive parts may become heated, it is possible to prevent surface cracking due to thermal history. We have included examples in our materials that demonstrate improved yield rates for semiconductor manufacturing equipment exposed to an environment with a processing chamber temperature of 180°C.

Company information
We believe that our mission is to evolve and propose surface treatment technologies, which are foundational technologies for manufacturing, have a history dating back to ancient times, and have evolved to support cutting-edge industries of each era, but have now become difficult for anyone to perform. This evolution begins with communication with our customers. We learn about the materials our customers use, understand the required functional characteristics, and study the environment in which the finished products will be used and the roles they are expected to fulfill. If necessary, we collaborate with universities and public research institutions. We then provide the optimal surface treatment technology.
