Abstract:
A flexible circuit having a desired bend region and at least two non-desired bend regions, the desired bend region separating the non-desired bend regions, the flexible circuit further comprising:(a) a first circuit path portion, to at least a portion of which electronic components may be coupled, including a first resin layer and a first conductive layer, the first resin layer extending across the desired bend region and into the non-desired bend regions, the first conductive layer defining at least one first circuit path in the non-desired bend regions and further defining a first gap across the desired bend region, wherein the first circuit path portion does not have a solder mask layer in the desired bend region; (b) a second circuit path portion, to at least a portion of which electronic components may be coupled, including a second resin layer and a second conductive layer, the second resin layer extending across the desired bend region and into the non-desired bend regions, the second conductive layer defining at least one second circuit path in the non-desired bend regions and further defining a second gap across the desired bend region, wherein the second circuit path portion does not have a solder mask layer in the desired bend region; (c) a central circuit path portion, disposed between the first resin layer and the second resin layer, the central circuit path portion including a third conductive layer and a non-conductive base layer, the third conductive layer disposed adjacent the first resin layer, the non-conductive base layer disposed adjacent the third conductive layer, the third conductive layer electrically connected to the first conductive layer in each non-desired bend region; and (d) a metal plate affixed at the non-desired bend regions to the second circuit path portion.
