Abstract

LA INVENCION SE REFIERE A UN TRANSDUCTOR DE SONIDO DE POLIVINILIDENO FLUORADO (PVDF) Y A SU PROCEDIMIENTO DE FABRICACION Y DE INTEGRACION EN UNA TARJETA DE PRODUCCION DE SEÑALES ACUSTICAS TRANSMISIBLES POR VIA TELEFONICA. EL PROCEDIMIENTO SE CARACTERIZA PRINCIPALMENTE PORQUE CONSISTE EN REALIZAR (10) BANDAS DE METALIZACION DE DOBLE CARA REPARTIDAS POR TODO EL ANCHO DE UNA BANDA DE PVDF DE GRAN LONGITUD Y DE MUY ESCASO ESPESOR, CORTAR (11) CADA BANDA DE METALIZACION EN CINTA UNITARIA, FIJAR (12) UNA PORCION DE CINTA EN UNA SITUACION PREDEFINIDA POR EL DISEÑO DE INTERCONEXIONES REALIZADO EN REVERSO DE LA TARJETA Y SUPRIMIR EL EXCEDENTE DE CINTA, A CONTINUACION, TENSAR LA CINTA (13), DE FORMA QUE PUEDA EMITIR SEÑALES ACUSTICAS CUANDO SE LE APLICA UNA TENSION. ESTE PROCEDIMIENTO ES MUY UTIL PARA ELABORAR TARJETAS DE PRODUCCION DE SEÑALES ACUSTICAS DE MUY ESCASO ESPESOR Y DE MUY BAJO COSTO.
