Process for manufacturing a PTC heating element and PTC heating element

A process for manufacturing a PTC heating element, wherein the PTC heating element comprises at least one PTC component and, on at least one side of the at least one PTC component, a carrier made of an electrically insulating material and permanently connected to the at least one PTC component, the process comprising the steps of:

• providing a coating formed of metallic material on a side of the carrier to be connected to the at least one PTC component;
• providing at least one contact field on a side of at least one carrier to be positioned facing away from the at least one PTC component by additionally providing the coating formed of metallic material on the side of the at least one carrier to be positioned facing away from the at least one PTC component;
• providing a connection of an area of the coating provided on the side of the at least one carrier to be connected to the at least one PTC component and an area of the coating provided on the side of the at least one carrier to be positioned facing away from the at least one PTC component by a connecting area of the coating;
• arranging solder material between the at least one side of the at least one PTC component, which side is to be permanently connected to the carrier, and the carrier to be connected to the least one side of the at least one PTC component after providing the coating formed of metallic material and after providing the at least one contact field and after providing the connection of the area of the coating provided on the side of the at least one carrier to be connected to the at least one PTC component and the area of the coating provided on the side of the at least one carrier to be positioned facing away from the at least one PTC component;
• and
• melting the solder material by induction soldering and thereby connecting the at least one PTC component to the carrier.
