摘要:
An electronic device includes: a package including a lid and a package base, the package being formed by bonding the lid to a joint surface of the package base using a bonding material; and a resin portion covering the package. The resin portion covers at least the package base and the bonding material, and at least a part of the resin portion has a section outline. The section outline has an outermost portion thereof in a direction parallel with a mount surface of the electronic device. The outermost portion is located below a lower surface of the lid in a direction perpendicular to the mount surface of the electronic device.

An airtight package has an insulating base having an opening approximately in the center and a recessed portion penetrating the insulating base in a thickness direction on a circumferential surface of the insulating base. The airtight package also has a lid sealed against the insulating base so as to block the opening. The lid is bonded to the insulating base in a manner that an edge of the lid overlaps the recessed portion exposed on an opening-side surface of the insulating base.
摘要:
The invention provides a piezoelectric oscillator that allows for fine adjustment of the frequency after resin molding, a manufacturing method therefor, and a mobile phone and an electronic apparatus using the piezoelectric oscillator. The piezoelectric oscillator can include a resonator package, in which a piezoelectric resonator element is housed, and a semiconductor device, in which an oscillation circuit that is electrically connected to the resonator package is incorporated. The resonator package and the semiconductor device can be fixed to corresponding different surfaces of an island portion of a lead frame, and resin molding is performed so that a transparent lid of the resonator package is exposed to the outside.
