Semiconductor Plating

Metal Finishing Solutions For Semiconductor Manufacturers

An essential component of electronic devices, semiconductors drive innovation and enable rapid advancement in communications, computing, healthcare, military systems, transportation, and clean energy. The Semiconductor industry has extremely demanding requirements for metal plating services to improve conductivity and wear resistance as products become smaller, more powerful, and highly mobile.

Equally important, the industry is regulated with tight standards for both production and process management, so working with the right metal finishing partner is essential to manage risk. Getting it right every time is an absolute necessity.

AOTCO delivers expert metal finishing for semiconductor tooling – and brings decades of experience providing engineering solutions for exotic substrates, ultra-thin layers, tight tolerances, new materials, 3D structures and more. We specialize in small, complex geometries, complex masking, multiple plating on the same piece, and developing solutions with our partners.
