Abstract
A method for producing a foil circuit board including a plurality of flexible electrically non-conductive and flexible conductive layers, which are laminated together. The non-conductive layers are positioned between the conductive layers and two of the conductive layers are the outermost surface layers of the foil circuit board. The circuit board includes flexible areas and rigid areas, and the flexible areas are provided by etching the board to remove at least part of one of the outermost surface layers and an adjacent underlying non-conductive layer.
Claims3
A method for producing a foil circuit board, said foil circuit board including a plurality of flexible electrically non-conductive and flexible electrically conductive layers, said plurality of electrically non-conductive and electrically conductive layers being laminated together to form said foil circuit board, said non-conductive layers being positioned between said conductive layers and two of said flexible conductive layers being outermost surface layers, said board including flexible areas and rigid areas, said method comprising a step of etching said board to remove at least part of one of said outermost surface layers and an adjacent, underlying non-conductive layer.
