Method for fabricating surface acoustic wave filter package

摘要

A method for fabricating a surface acoustic wave filter chip package includes: mounting a surface acoustic wave filter chip on a substrate; forming a underfill in a space between the substrate and the chip; forming a metal shield layer on a whole outer wall of the chip by using a spray process; and molding resins on the metal shield layer. The metal shield layer is formed from a conductive epoxy with the use of a spray nozzle.
