Electronic device including housing with fiducial mark and method for manufacturing the same
According to certain embodiments, an electronic device comprises: a front case including a seating portion, and a display module disposed in the seating portion; wherein the front case includes a first fiducial mark, wherein the first fiducial mark includes: a first fiducial gap; a first area surrounding at least a portion of the first fiducial gap having a first surface roughness; and a second area exclusive with the first area, having a second surface roughness that is different from the first surface roughness.
1. An electronic device comprising:
a front case including a first surface and a seating portion forming at least a portion of the first surface, and
a display module disposed in the seating portion to face the first surface;
wherein the front case includes a first fiducial mark formed on the first surface,
wherein the first fiducial mark includes:
a first fiducial gap;
a first area surrounding at least a portion of the first fiducial gap having a first surface roughness; and
a second area disposed not to overlap with the first area when viewed in a direction perpendicular to the first surface, and having a second surface roughness that is different from the first surface roughness.
2. The electronic device of claim 1 , wherein the first fiducial gap comprises a through hole.
3. The electronic device of claim 1 , wherein the first fiducial gap comprises a recess, and a level of the first fiducial gap is lower than a level of the first area and a level of the second area.
4. The electronic device of claim 1 , wherein the second area surrounds at least a portion of the first area.
5. The electronic device of claim 1 , wherein the first surface roughness is greater than the second surface roughness.
6. The electronic device of claim 1 , wherein the first area is circular-shaped or polygonal-shaped.
7. The electronic device of claim 1 , further comprising an adhesive portion configured to receive an adhesive.
8. The electronic device of claim 1 , wherein the front case further includes a second fiducial mark formed in a different position from the first fiducial mark,
wherein the second fiducial mark includes:
a second fiducial gap;
a third area surrounding the second fiducial gap having a third surface roughness; and
a fourth area not overlapping the third area having a fourth surface roughness different from the third surface roughness.
9. The electronic device of claim 8 , wherein the third surface roughness is substantially equal to the first surface roughness.
10. The electronic device of claim 8 , wherein the fourth surface roughness is substantially equal to the second surface roughness.
11. The electronic device of claim 8 , wherein the second fiducial gap is a through hole or a recess, and a level of the second fiducial gap is lower than a level of the third area and a level of the fourth area.
12. The electronic device of claim 8 , wherein the fourth area surrounds the third area.
13. The electronic device of claim 8 , wherein the surface roughness of the third area is greater than the surface roughness of the fourth area.
14. The electronic device of claim 8 , wherein the third area is circular-shaped or polygonal-shaped.
15. The electronic device of claim 1 , wherein the first area and second area include hatched areas forming, respectively, the first surface roughness and the second surface roughness in a material of the front case.
