EMI shielding method of semiconductor packages

摘要

Disclosed is an EMI shielding method of semiconductor packages, including a tape attaching step of attaching an edge of a tape to a lower side of a frame to dispose the tape inside an inner circumferential side of the frame, a tape cutting step of forming holes through the tape at regular intervals, a semiconductor package fastening step of disposing edges of lower sides of the semiconductor packages on an upper side of the tape so that bumps, formed on the lower sides of the semiconductor packages, are inserted into the holes in the tape to thus fasten the semiconductor packages at regular intervals to the upper side of the tape, and a coating step of performing a coating operation over the tape to form a coat on the semiconductor packages and the upper side of the tape.

主权项

1. An EMI shielding method of semiconductor packages, comprising:
a tape attaching step (S10) of attaching an edge of a tape (10) to a lower side of a frame (1) to dispose the tape (10) inside an inner circumferential side of the frame (1); a tape cutting step (S15) of forming holes (11) through the tape (10) at regular intervals; a semiconductor package fastening step (S20) of disposing edges of lower sides of semiconductor packages (20) on an upper side of the tape (10) so that bumps (21) formed on the lower sides of the semiconductor packages (20) are inserted into the holes (11) in the tape (10) to thus fasten the semiconductor packages (20) at regular intervals to the upper side of the tape (10); and a coating step (S30) of performing a coating operation over the tape (10) to form a coat (30) on the semiconductor packages (20), fastened to the upper side of the tape (10), and the upper side of the tape (10), wherein the coat (30) is formed on five sides other than the lower sides of the semiconductor packages (20).
