Abstract

Se provee una barrera RFI/EMI de plástico metalizado contra energía electromagnética para una tarjeta circuito (32) donde la barrera está formada de una caja de cubierta con dos medias carcazas para cubrir la tarjeta (32), la primera mitad de carcasa teniendo paredes laterales de pestaña solidas rodeando la tarjeta (32) y la segunda mitad de carcaza (24) teniendo una pestaña (26) formada por proyecciones (28) espaciadas cercanamente en forma de placas, las proyecciones confrontadas, estando en contacto eléctrico con y emparejadas en toda su longitud con substancialmente toda la periferia de las paredes laterales de la primera mitad de carcaza. Las proyecciones (28) están espaciados preferiblemente con una separacion de menos que 1/4 de longitud de onda de cualquier armonica de la destinada frecuencia de operacion, generalmente por encima de la décima armonica. Una barrera (18) puede ser proporcionada para recibir las proyecciones (28) en la parte de afuera de las paredes laterales, y espaciadas cercanamente conectando pines arreglados alrededor de la periferia de la tarjeta (32) que puede extenderse entre la primera y segunda mitad de carcaza a través de las perforaciones planas (34) conectadas a lo largo de los bordes de las paredes laterales.
