Copper Wire Connections And Corrosion

Tanaka precious metals to start producing copper bonding wire in 3 locations

Tanaka Holdings Company Limited announced that Tanaka Denshi Kogyo KK which boasts the world's leading share in bonding wire manufacturing has decided to produce copper bonding wire in Japan, China and Singapore enabling more stable product supply while diversifying the risk of natural disaster and damage to social infrastructure in the product supply chain. With the investment of about JPY 1 billion, the company starts producing copper wire in China Plant located in Hangzhou and triples the production capacity of the Singapore Plant, to form a 3 plant production network with the existing Saga Plant located in Yoshinogari, Saga City, Japan. It will double the companywide current production capacity up to 200 million meters per month by the end of fiscal 2011. Along with this production increase, the company starts producing a new CLA-1A copper wire product which could lower the running costs against current products and has improved bondability. As the gold price soaring, gold is being replaced by cheaper copper in bonding wire used to connect the integrate circuits in semiconductors to external electrodes. Conventional copper wire is rapidly deteriorated by surface oxidization, resulted to poor quality stability but by the improvement of processing technologies including surface treatment has improved the corrosion resistance and stability of recent copper wire. Demand expansion for copper wire is accelerating around the emerging Asian countries such as China where low cost products are in high demand. It is believed that 1.0 billion meters to 1.2 billion meters of bonding wire is currently produced each month and although copper wire only accounts for around 15% but this is expected to expand to approximately 40% in 2013. <script type="text/javascript"> var iframesrc="http://www.steelguru.com//steelnews/index?id=214186" document.
