...Raathai Molian; Pranav Shrotriya; Pal Molian The traditional “evaporation∕melt and blow” mechanism of C O 2 laser cutting of aluminum nitride (AlN) chip carriers and heat sinks suffers from energy losses due to its high thermal conductivity, formation of dross, decomposition to aluminum...

... has also been employed to slice other brittle materials such as alumina, quartz, glass, and ceramics. The manufacturing process of wiresaw is a free abrasive machining (FAM) process. Specifically, the wiresaw cuts brittle materials through the “rolling-indenting” and “scratch-indenting” processes...

...C. F. Cheung; W. B. Lee; W. M. Chiu Dam-bar cutting is an essential trimming process in which the dam-bars in between the leads of Integrated Circuit (IC) packages are removed after encapsulation and deflashing. There are stringent requirements imposed on the quality of the sheared dam-bar edges so...
