    摘要: 1. A method for manufacturing a circuit board featuring conductive patterns, said method comprising the following steps of: i) affixing a conductive layer, such as a metal foil (3), to a substrate material (1) selectively, such that a part of the conductive layer, such as the metal foil (3), comprising desired areas (3a) for the final product and narrow areas (3c) between the final product's conducting areas, is affixed to the substrate material (1) by means of a bond (2), and removal-intended more extensive areas (3b) of the conductive layer, for example the metal foil (3), are left substantially unattached to the substrate material in such a way that the removable area (3b) is in attachment with the substrate material (1) by not more than its edge portion to be patterned in a subsequent step ii) and possibly by sites which preclude a release of the removable areas prior to a step iii); ii) patterning, by a removal of material, the conductive layer, such as the metal foil (3), from narrow gaps between the desired conducting areas (3a), and from an outer periphery of the area (3b) removable in a solid state, for establishing conductor patterns; iii) removing the removable areas (3b), not affixed to the substrate material (1), from the conductive layer, such as the metal foil (3), in a solid state after the conductive layer's edge area, which was removed from the removable area's outer periphery during the course of step ii), no longer holds the removable areas (3b) attached by their edges to the substrate material.
