Electronic component device
An image pickup unit, which is an electronic component device, includes: a stacked device which is an electronic component including an external electrode; and a wiring board. The wiring board has a first principal surface and includes a bonding electrode and an alignment mark on the first principal surface, the external electrode of the electronic component is bonded to the bonding electrode, and on the first principal surface, an area of a region in which a first region where the bonding electrode is virtually moved in a predetermined first direction, and the alignment mark are superimposed on each other is less than 50% of an area of the alignment mark.
1 . An electronic component device comprising:
an electronic component including an external electrode; and
a wiring board, wherein
the wiring board has a first principal surface,
the wiring board includes a bonding electrode and an alignment mark on the first principal surface,
the external electrode of the electronic component is bonded to the bonding electrode, and
on the first principal surface, an area of a region in which a first region where the bonding electrode is virtually moved in a predetermined first direction and the alignment mark are superimposed on each other is less than 50% of an area of the alignment mark.
2 . The electronic component device according to claim 1 , wherein
the alignment mark is not superimposed on the first region.
3 . The electronic component device according to claim 1 , wherein
the alignment mark is substantially identical in shape and size to the bonding electrode.
4 . The electronic component device according to claim 1 , wherein
the alignment mark and the bonding electrode are in a substantially round shape.
5 . The electronic component device according to claim 1 , wherein a total of the area of the region in which the first region and the alignment mark are superposed on each other and an area of a region in which a second region where the bonding electrode is virtually moved in a second direction orthogonal to the first direction and the alignment mark are superposed on each other is less than 50% of the area of the alignment mark.
