Abstract

SE FORMA UNA RESISTENCIA DE TELEFONO POR UN SUSTRATO CERAMICO (10) QUE TIENE UNA PELICULA RESISTIVA (11, 12) SOBRE SI Y PATILLAS (33, 34) SOBRE UN BORDE (B) DEL SUSTRATO (10) Y CONECTADOS A LA PELICULA (11, 12). SE PREVE UNA REGION FRIA EN FORMA DE U (40, 42) SOBRE EL SUSTRATO (10) ALREDEDOR DE AL MENOS LA MAYOR PARTE DE LA PELICULA (11, 12), Y SE CONSTRUYE ASI DE MANERA QUE LA APLICACION DE ALTAS TENSIONES DE SOBRECARGA A LAS PATILLAS (33, 34) PROVOQUEN LA FRACTURA DEL SUSTRATO (10) ENTRE LOS BRAZOS DE LA U. LAS PIEZAS DE SUSTRATO RESULTANTES SE MANTIENEN POR LAS PATILLAS (33, 34) PARA EVITAR QUE LOS RESTOS DE LA FRACTURA SE DISPERSEN.
