摘要

A method of manufacturing a part-mounting package includes: forming a first through-hole in a first insulating sheet and forming a second through-hole whose opening area is larger than the first through-hole in a second insulating sheet; forming a penetration conductor covering an inner surface of the second through-hole and forming a conductor layer on a surface of at least the second insulating sheet; laminating the first insulating sheet and the second insulating sheet where center positions of the first through-hole and the second through-hole are matched to each other; causing linear laser division grooves to pass through a center of the first through-hole and the second through-hole; and dividing the sheet laminated body along the laser division grooves, and causing the side surface recess part and the end face through-hole conductor to appear.

說明書

(15) The part-mounting package in any one of the technical concepts (8) to (13), wherein a length of the second recessed region in a thickness direction of the substrate base is longer than a length of the first recessed region in the same direction.

(16) The part-mounting package in any one of the technical concepts (8) to (15), wherein the electronic part is a quartz device.
