Flexible printed circuit structures

摘要

Flexible printed circuit structures may be provided that have regions with different electrical and mechanical properties. A flexible printed circuit substrate may be formed from a sheet of polymer having different regions with different thicknesses. The flexible printed circuit substrate may be bent in a thin region of the substrate. Additional flexible printed circuit substrate portions may be coupled to the flexible printed circuit substrate. The additional portions may have different substrate thicknesses. A groove or other recess may be formed in a flexible printed circuit substrate to promote bending. Openings may also be formed in the substrate to promote bending.

主权项

1. Flexible printed circuit structures, comprising:
a polymer sheet having a first region with a first thickness and a second region with a second thickness that is thinner than the first thickness; and patterned metal traces on the polymer sheet, wherein the polymer sheet is bent within the second region, and wherein the polymer sheet is bent along an axis and wherein the polymer sheet comprises a groove along the axis.
