  • Method of fabricating thermal printing head
    Patent number: 3950200
    Abstract: A method of fabricating a thermal printing head by printing a circuit pattern of resistive elements and electric conductors on one surface of a flat paper sheet, covering the circuit pattern and surface of the flat paper sheet with a carrier layer of a substantially transparent methacrylic acid resin, peeling off the flat paper sheet, placing the remaining carrier layer carrying the circuit pattern over a surface of a pre-shaped insulating substrate with the circuit pattern being laid downward, and heating the carrier layer placed on the substrate to cause the carrier layer to be burned off and cause the circuit pattern to adhere to the surface of the substrate.
