Maximizing the Process Capability of Singulation Machine by Dual Work Piece Cutting on Circular Tape Frame

Mariane Mendoza, Maria Virginia Buera & Frederick Ray Gomez · Journal of Engineering Research and Reports · 2021

Tape saw singulation is the process where a strip was mounted on the tape attached on the frame and then sawn into single units. Circular tape saw singulation only caters one panel of the two-paneled strip which was found to be consuming with the machine capacity and resources. D...
