Through-Life Monitoring of the impact of vibration on the reliability of area array packages using Non- Destructive Testing
In order to keep up with the demands for faster, cheaper and smaller electronics, the packaging industry has evolved tremendously. Area array packages like flip chips and ball grid arrays are therefore widely used in modern day electronics. However, from the reliability standpoint, solder joints in …

Characterisation and Evaluation of Thermally Treated Recycled Glass for Mass Finishing and Superfinishing Processes
This thesis presents the work on the characterisation and evaluation of an entirely new mass finishing product based wholly on thermally treated recycled glass, which acts as both a bond and abrasive for mass finishing and superfinishing processes. The recycling of glass is excellent in respect of …

Non-contact surface inspection
This thesis describes the development of a non-contact inspection system, used in providing a comparative method for gauging a surface. The purpose of this system is not to measure the 3-D shape of a part. The volume difference between the part to be inspected and a master, is merely part of the …
