  • Patent number: 8628831
    Abstract: The present invention relates to the field of selective metallization, and in particular to preparing a polymer article for selective metallization by submerging the article in a first liquid, and while submerged irradiate the article by a laser beam the area of the article on which the metal is to be deposited. An activation step, prior to the selective metallization, comprises submerging the article in an activation liquid for depositing seed particles in the selected area. The irradiation of the selected area is proportionate so as to cause a temporary melting of the polymer in the surface of the selected area of the polymer article. The invention is advantageous in that the preparation may be performed with a relatively high scan rate across the polymer article, and in that a quite limited use of toxic chemicals.
