Abstract: Utilizing multiple cutting devices in series in a patterning process of a workpiece. In one implementation, multiple sets of cutting devices can be used in series. The cutting devices may be lasers, and each of the sets of lasers may operate at different power levels. In one embodiment, high power lasers are used initially for an initial coarse ablation of a workpiece. The workpiece is then processed by lower power lasers for fine ablation. The cutting lasers can be arranged at any point in the process. In one implementation, a slug removal process is included at the end of the processes if laser cutting is involved.

Abstract: A process involves building up a terminal by starting with a thin, long material and then manipulating it to thicken up portions of a circuit where needed. In various implementations, the material can be rolled and squashed, or folded up to form the thickened portions of a circuit. Once it is squashed or folded up, the layers can be welded together. This process allow the initial printing of a thin conductor, which can then be thickened later in one of several ways.
