Single and double-sided flexible printed circuits from willpower are utilized in a wide variety of electronic assemblies from simple antennas to complex control circuitry. The single and double-sided flexible circuits are produced using: adhesive based polyester (“PET” / “PEN”) or polyimide (PI) film substrates with copper thicknesses ranging from 18um to 140um. These circuits can be provided in single pieces, multiple up arrays, or in rolls.
