<p>PURPOSE:To provide the manufacturing method, of a trimmer capacitor, whose manufacturing cost is low by proposing the manufacturing method of a rotor which is suitable for an automatic production process. CONSTITUTION:Before a rotor constituting the title trimmer capacitor is baked, a through-hole electrode is formed by temporarily stamping it to be a rotor shape and by stamping a through hole. After that, the rotor shape is stamped fixedly. Thereby, a manual operation in conventional cases is eliminated, the rotor is produced automatically and a low-cost trimmer capacitor can be achieved.</p> |
