Abstract
A sealing member for an electronic component package includes, on another principal surface of a base material constituting the sealing member for the electronic component package, an external terminal electrode, a wiring pattern, and a resin material. The external terminal electrode is to be electrically coupled to an outside of the electronic component package. The wiring pattern is configured to couple an electronic component element on one principal surface of the base material to the external terminal electrode. The resin material is layered over the other principal surface and the wiring pattern. The external terminal electrode is layered over the wiring pattern and the resin material.
Claims7
A sealing member for a piezoelectric resonator device, constituting a part of a package for hermetically enclosing a piezoelectric resonator plate inside the piezoelectric resonator device and having a first principal surface on which a piezoelectric resonator plate is to be mounted,
- wherein the sealing member comprise:
- a wiring pattern extending from the first principal surface to a second principal surface via an internal face of a through hole formed through a base material constituting the sealing member so as to be coupled to an electrode of the piezoelectric resonator plate, the second principal surface being located opposite the second principal surface;
- an infill layer filling the through hole and sealing the through hole;
- a resin material provided on the second principal surface and covering an opening face of the through hole;
- and
- an external terminal electrode provided on the second principal surface and electrically coupled to the wiring pattern,
- wherein the resin material is layered over the second principal surface and the wiring pattern, and the external terminal electrode is layered over the wiring pattern and the resin material, and
- wherein the external terminal electrode is layered on the wiring pattern at a peripheral area along and lateral to a peripheral edge of a part of a layered portion of the resin material so that the wiring pattern is in direct contact with an outer peripheral edge of the external terminal electrode, and at least a part of the peripheral edge of the resin material is sandwiched and enclosed by the wring pattern and the external terminal electrode.
