According to one embodiment is a flexible circuit comprising a flexible base, a conductive polymer supported by the base, and an integrated circuit component having an elongated electrical contact, wherein the elongated electrical contact penetrates into the conductive polymer, thereby providing a robust electrical connection. According to methods of certain embodiments, the flexible circuit is manufactured using a molding process, where a conductive polymer is deposited into recesses in a mold, integrated circuit components are placed in contact with the conductive polymer, and a flexible polymer base is poured over the mold prior to curing. In an alternative embodiment, a multiple-layer flexible circuit is manufacturing using a plurality of molds.
