Mechanical tape separation package
View Patent ↗A method of fabricating a plurality of electronic component packages includes coupling a tape to a panel. Electronic components are coupled to the tape and encapsulated to form a molded wafer. The molded wafer is mechanically separated from the panel without heating by breaking a mechanical separation adhesive of the tape. By mechanically separating the molded wafer from the panel without heating, warpage of the molded wafer associated with heating is avoided.
1. An assembly comprising:
a tape comprising:
an electronic component permanent adhesive;
a first support tape coupled to the electronic component permanent adhesive;
a mechanical separation adhesive coupled to the first support tape;
a second support tape coupled to the mechanical separation adhesive; and
