Thermal head for serial printer

Abstract

Abstract PURPOSE:To exactly connect the terminals with flexible print plates as well as enable low-cost materials as conductor of electrode to be used by a method in which copper used for the conductor of electrode, chromium is used for the contact layer with the ground, nichrome is used for the contac layer with wear-resistant layer, nickel layer is provided on the copper layer of the terminals, and copper layer is provided on the nickel layer. CONSTITUTION:A copper layer 11 as the main conductor of electrode conductors is provided, and a chromium layer 12 is interposed between the base plate 1 and the copper layer 11. A nichrome layer 13 is provided between the copper layer 11 and a wear-resistant layer 4. In the terminals, a nickel layer 14 is provided on the copper layer 11 as the main conductor of the electrode conductors and a copper layer 15 is again provided on the layer 14. On the flexible print plate 6 side, a preliminary solder 16 is provided to the copper conductor at the tip, and the solder 16 is placed the layer 15 of the terminals and hot-welded. Since the chromium layer 12 is provided on the ground side of the layer 11 as the main conductor and the nichrome layer 13 is provided on the wear-resistant layer 4 side, etching for forming patterns can be made very exactly.
