Wired circuit board assembly sheet including striated portions for enhancing rigidity
A wired circuit board assembly sheet includes a plurality of wired circuit boards spaced to each other, and a plurality of striated portions extending between the respective wired circuit boards along a direction intersecting the lengthwise direction of the wired circuit boards.
1. A wired circuit board assembly sheet comprising:
a support sheet;
a plurality of wired circuit boards spaced apart with respect to each other and supported by the support sheet; and
a plurality of rigidity-enhancing, striated portions disposed on a surface of the support sheet and extending between the respective wired circuit boards along a direction intersecting the lengthwise direction of the wired circuit boards,
wherein the striated portions are disposed on the surface of the support sheet but are not disposed on any of the wired circuit boards.
2. The wired circuit board assembly sheet according to claim 1 , wherein the striated portions are formed of a metal and/or a resin.
3. The wired circuit board assembly sheet according to claim 1 , wherein the striated portions are spaced in parallel to each other.
4. The wired circuit board assembly sheet according to claim 1 , wherein a bisector of an angle formed by intersecting straight lines along the lengthwise direction of the wired circuit boards and the lengthwise direction of the striated portions is parallel to the lengthwise direction of the wired circuit board assembly sheet.
5. The wired circuit board assembly sheet according to claim 1 , wherein the striated portions are arranged along directions intersecting both the lengthwise direction of the wired circuit boards and a direction perpendicular to the lengthwise direction of the wired circuit boards.
6. The wired circuit board assembly sheet according to claim 1 , wherein the striated portions are arranged on the support sheet in regions between the respective wired circuit boards.
7. The wired circuit board assembly sheet according to claim 1 , wherein the wired circuit boards are suspension board with circuits.
