Abstract

Se describe un metodo y aparato de recubrimiento por atomizacion electrostatica variable. Un recubrimiento liquido es formado al atomizar gotas de liquido sobre un sustrato o una superficie de transferencia de una cabeza de atomizacion electrostatica que produce una niebla de gotas y un recubrimiento humedo en respuesta a un campo electrostatico. Durante la atomizacion, el campo electrostatico es repetidamente alterado para cambiar el patron depositado por las gotas. El recubrimiento humedo se puede poner en contacto con dos o mas dispositivos de captacion y colocacion que mejoran la uniformidad del recubrimiento.
