MULTILAYERED BOARD COMPRISING FOLDED FLEXIBLE CIRCUITS AND METHOD OF MANUFACTURE |
摘要 |
An easier and cheaper way to obtain multilayer circuit board is by using a flexible circuit board (200) and folding it in an organized pattern. Flexible circuit has the unique property of being a three-dimensional circuit that can be shaped in multiplanar configurations, rigidized in specific areas, and molded to backer boards for specific applications. The folded circuit is fabricated from a series of foldable circuit board strips (220) and rigid circuit board strips (210) which are interconnected, folded, and bonded into a composite structure. The foldable strips (220) may have prefolds, arranged so that a group of upper foldable strips (240) and lower foldable strips (220) are folded in opposite directions. A plurality of intermediate portions (230) are stacked on each other by the folding the foldable strips (220) in opposite directions. The folded circuit (200) can be bonded after a first fold, or folded further to achieve a greater reduction in area and subsequently be bonded as a composite multilayer structure. |
