Chip wire bonding

WebThe first technique was called controlled collapse chip connection (C4), and it displaced wire bonding, giving increased input/output density at a lower cost.15 The C4 process starts by depositing under bump metallurgy (UBM) onto the bonding pads of the chips to supply good adhesion between the bonding pads and the bumps. WebFig. 3. Wire bonding process mechanism. C. The Chip-On-Lead Tapeless Leadframe Tapeless Chip-On-Lead package is a leadframe-based package carrier or platform in which the leads footprint will be formed by back-etching process. The plant has a lot to gain with tapeless package – cheaper leadframe cost, Copper wire
