Abstract:
A process for manufacturing a folded flexible circuit board comprising the steps of:(a) providing a circuit board comprising a lower rigid portion, a plurality of lower foldable strips electrically connected to the lower rigid portion, a plurality of intermediate portions connected at a first end to a second end of the lower foldable strips, a plurality of upper foldable strips connected to a second end of the intermediate portions, and a connector board connected to an opposite end of said upper foldable strips; (b) folding said lower foldable strips and said upper foldable strips diagonally in opposite directions to each other so that each of the intermediate portions at least partially stack upon each other; (c) folding said lower rigid portion back on the stack of intermediate portions by folding said lower foldable strips horizontally so that said lower rigid portion stacks on said intermediate portions; and (d) folding the connector board onto the upper foldable strips and the stack of intermediate portions by folding said upper foldable strips horizontally so that said connector board stacks on the upper foldable strips and the intermediate portions.
