Lid for use in packaging an electronic device and method of manufacturing the lid

摘要

A lid for use with a plate-shaped base to seal an electronic device such as a SAW device includes a top portion, a wall structure extending from the top portion, and a lip connected to the lower end of the wall structure. The lip extends outwards from an outer surface of the wall structure by 10-500 mum and has solder on an inner surface thereof. The lid can be soldered to a plate-shaped base to form a package. The lid can be conveniently formed by performing drawing of a metal strip coated with solder to define a recessed shape, and then severing a flange of the recessed shape to define the lip.
