Abstract

Se prueban laminados en cuanto a la presencia de agujeros pequenos. Por ejemplo, cuando un laminado se esta moviendo a traves de una maquina de procesamiento en una direccion a lo largo de una longitud del laminado, se aplica un vacio a una superficie del laminado y la superficie del laminado es inspeccionada para detectar liquido que ha penetrado desde otra superficie del laminado a traves de agujeros pequenos a la superficie inspeccionada.
