Picking Dies Off of Dicing Tape

Typically providers of dicing tape provide a specification sheet on material but rarely does it include any information on pick force required to remove the die from the tape.  In a Journal of Solid Mechanics and Material Engineering article in 2010 LINTEC Corporation published a study of pick force versus peel strength.  In it a way to approximate pick force required was introduced.

Study on Peeling Behavior

Formula for Determining Pick Force Required



The study concluded that there was a correlation, but the study focused on die attached adhesives in sheet format not in dicing tapes themselves.  It does beg the question though can dicing tape pick force be determined by peel strength.  While this paper provides no definitive answer I may be able to comment on this in a future posting.
