Abstract
This invention is a process for producing metal strip resistors, i.e., forming the two electrodes at the two ends of an metal strip with thick electroplating and laying a layer of coating on the surface of the metal strip for heat radiation (a metal cooling plate may be pasted onto the coating when necessary). The producing procedures include rolling, punching, electroplating, cutting, grooving, coating, fixing the cooling plate, and drying. The finished product is the metal strip resistor described in this invention. The said electrode production method can maximize the contact surface between the electrodes and the base strip to pass more current and decrease the resistance valve (usually to 0.0001 ohm). The heat ventilating plate on the base strip can facilitate heat emission to stabilize the resistance valve and enhance its capacity.
