Abstract
SE PROPONE UN METODO Y UN DISPOSITIVO PARA LA FABRICACION DE SENSORESPREVISTOS EN PARTICULAR PARA LA DETERMINACION DE FUERZAS DE PRESION. EN LA TECNICA DE CAPA GRUESA SE APLICA PRIMERAMENTE POR LO MENOS SOBRE UNA PLACA SOPORTE (10) UNA CAPA AISLANTE (14), SOBRE ELLA UNA CAPA RESISTIVA SENSIBLE A LA PRESION (12) Y FINALMENTE PISTAS CONDUCTORAS (13). EL CONJUNTO DE LA CAPA (1114) SE COMPRIME A CONTINUACION JUNTO CON UNA MASA DE MOLDEO DE PLASTICO (15) EN UNA ESTAMPA DE COMPRESION (20-22). A CONTINUACION SE RETIRA LA PLACA SOPORTE (10) DE LA PIEZA PRENSADA.
