Abstract: The formation of flash during plastic encapsulation of electronic devices may be reduced or eliminated and the mold made substantially self-cleaning by modifying the mold chases so that the edges of the channels, runners, gates, and/or other locations containing plastic have a wedge shaped edge region extending to the parting plane of the mold.
