Abstract
A method of manufacturing semi-manufactured PTC heating elements () comprises the steps of providing an electrically insulating support foil (), providing an electrically conductive foil () from which at least two electrically conductive patterns separated from one another are to be formed, and laminating a PTC compound () between the electrically insulating support foil and the electrically conductive foil, wherein the PTC compound has adhesive properties for bonding the laminate together. Preferably, the electrically insulating support foil, the electrically conductive foil, and the semi-manufactured PTC heating elements are provided on rolls. PTC heating elements are manufactured by means of cutting the semi-manufactured PTC heating elements into suitable pieces, patterning and etching the electrically conductive patterns, and attaching electrically conductive terminals to the electrically conductive patterns.
