Abstract
PLACA DE CIRCUITO ELECTRICO CON SUSTRATO METALICO ELECTRICAMENTE CONDUCTIVO, QUE LLEVA UN RECUBRIMIENTO DE UNA CAPA DE PORCELANA, AL MENOS SOBRE UNA DE SUS SUPERFICIES, Y UN CIRCUITO ELECTRICO IMPRESO SOBRE DICHA PLACA DE PORCELANA. CARACTERIZADA PORQUE SE DOTA A LA CHAPA DE ACERO (13) DE TERMINALES (15) DE PUESTA A TIERRA; PORQUE SE CREA UN EFECTO DE CAPACITANCIA ENTRE EL CIRCUITO IMPRESO (11) Y LA CHAPA DE ACERO (13), ESTANDO DETERMINADO EL VALOR DE LA CAPACIDAD POR EL AREA DE CONTACTO ENTRE DICHO CIRCUITO IMPRESO Y LA CAPA DE PORCELANA (14) Y POR EL ESPESOR DE DICHA CAPA DE PORCELANA; PORQUE EL CIRCUITO IMPRESO TIENE UN CONDUCTOR QUE SE IMPRIME CON PARTES DE GRAN ANCHURA Y CON OTRAS DE MENOR ANCHURA, PARA FORMAR EL AREA DE CONTACTO DESEADA CON LA CAPA DE PORCELANA.
