WebAug 17, 2001 · We have a Watch IC chip that has to be wirebonded using Ultrasonic aluminium wedge bonder. The wire dia is 1.25mil. The PCB is made of G10 Glass epoxy copper clad laminate. The copper thickness is 18 microns. The Nickel plating thickness is 7 microns and the gold plating thickness is 0.05 microns. Wire bonding is the method of making interconnections between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Although less common, wire bonding can be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another. Wire bonding is generally considered the most cost-effective and flexible interconnect technology and is used to assemble the vast majority of semi…
