IC Interconnect successfully uses a 0.1 um thick gold layer where other companies require at least 1 um of gold or thicker. "Many people don't believe that a thinner gold layer can hold up to the stress caused by their application," says Christine Jauernig, process engineer for IC Interconnect. "Products made with our Ni/Au process have been tested and qualified by several customers."
Nickel/gold pad resurfacing also benefits copper-based ICs. To avoid Cu corrosion in plastic packaging, there are two solution paths -- aluminum plating on copper pads, which is expensive, or nickel/gold plating on copper pads. The second option is maskless, eliminating costs associated with thin film sputter, photo lithography and metal etch.
"Electroless Ni/Immersion Au is an inexpensive method to enable standard gold wire bonding to be extended to the thermal demands (200(degrees)C) required of today's state-of-the-art electronics," says Curt Erickson, president of IC Interconnect.
This application contributes to IC Interconnect's extensive list of manufacturing qualifications for automotive, aerospace and other high-reliability applications. The company is currently ISO/TS 16949.
