SURFACE ACOUSTIC WAVE FILTER PACKAGE, MANUFACTURING METHOD THEREOF, AND PACKAGE SHEET USED IN THE PACKAGE CAPABLE OF PREVENTING SPACING BETWEEN SHIELD LAYER AND SHEET

摘要

PURPOSE: A surface acoustic wave filter package, a manufacturing method thereof, and a package sheet used in the package are provided to prevent spacing between a shield layer and a sheet by improving a bond between the external patterns to the package sheet. CONSTITUTION: A package sheet(51) used in a SAW(Surface Acoustic Wave) filter package includes an external pattern and a circular bur prevention hole. The external pattern(52) is formed with a predetermined width along an edge line of a position where a plurality of SAW filter chips are implemented. The external pattern contacts with the SAW filter chip and a metallic shield layer formed on the package sheet. The circular bur prevention hole(53) is adjoined to an edge portion of the position for the SAW filter chips. A cutting line for cutting the plurality of SAW packages penetrates through the circular bur prevention hole.
