Semiconductor Plating

Metal Finishing Powers Advanced Manufacturing

Precious Metal Plating for Semiconductor Tooling

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.


Gold and Electroless Nickel Plating Solutions for Semiconductor Tooling

Gold and electroless nickel are widely used in the semiconductor industry for their properties which include gold's reflectivity, conductivity, and heat dissipation, as well as electroless nickel's consistent application and chemical resistance. We also plate uncommon substrates including Gold on Tungsten (W), Gold on Molybdenum (Mo) and others.

AOTCO brings deep experience working with some of the most demanding materials needed for semiconductor tooling. AOTCO’s broad range of metal finishing technologies allows us to serve both common and specialized customer needs including:
