ABSTRACT:
A process for releasing a runner or gate from an electronic device on a laminate plate after molding process is included. The area of the laminate plate designed to be covered with molding compound is cleaned in advance by appropriate physical and chemical process to enhance the adhesion property, and the area to be covered by the runner or gate is protected from the cleaning process to maintain the original property of low adhesion to the laminate plate. The runner or gate can be easily released from the laminate plate without damage to the molding compound after the molding process, and the yield of the electronic device is increased.
