  • Flat coil transformer for electronic circuit boards
    Patent number: 4080585
    Abstract: A flat coil transformer on an electronic circuit board. The primary winding consists of a first helical conductive pattern formed by alternately spaced straps of a first series of conductive straps on one surface of the circuit board, alternately spaced straps of a second series of straps on the opposite surface of the circuit board, and alternately spaced holes of first and second generally parallel series of conductive coated holes extending through the board and connecting together the alternately spaced straps of the first and second series of straps. The secondary winding consists of a second helical conductive pattern formed by the remaining alternately spaced straps of the first series of straps, the remaining alternately spaced straps of the second series of straps, and the remaining alternately spaced holes of the first and second series of holes connecting together the remaining alternately spaced straps of the first and second series of straps.
