Preliminary analysis indicated that 42.2% of the yield losses during the wire bonding of BGA packages was due to Non-stick on Pad (NSOP). The main focus of this project was to optimise the processing parameters to enhance the adhesion between the ball bond and bond pad, so as to reduce NSOP occurrence. | URI: | http://hdl.handle.net/10356/5710 | Schools: | School of Mechanical and Aerospace Engineering | Rights: | Nanyang Technological University | Fulltext Permission: | restricted | Fulltext Availability: | With Fulltext |
