Semiconductor Electroplating Precious Metals

Precious Metals

Technic originated as a supplier of precious metals to the jewelry industry in the 1940’s. In the 1950’s Technic expanded their precious metal expertise to the electronics industry. Today Technic is the one of the leading suppliers of precious metal specialty chemistry to the electronics industry. Technic’s noncyanide gold processes are the most widely used for semiconductor applications. Our sulfite gold processes not only provide a gold bath that is free of cyanide they are also free of harmful additives such as thallium and arsenic. In addition we continue to provide cyanide gold processes for advanced gold bumping and other technologies.

Elevate® Gold 7990

Electrolytic sulfite gold process that produces pure, soft gold deposits. Operates at an acidic pH, making it compatible with almost all photoresists. Elevate Gold 7990 produces a bright deposit without the use of harmful grain refiners like thallium and arsenic. Provides excellent coplanarity and step coverage.
