Abstract: Various structures or components can include plated surfaces or other parts. For example, an article can include a base and a plated part with a limit artifact that results from plating adjacent a non-plateable surface; the limit artifact can be disposed away from the base. Exemplary limit artifacts include lack of protrusions, smooth upper surfaces, and curved surfaces, where a curved surface can transition between a smooth upper surface and an irregular side surface. Exemplary plated structures can be tube-shaped or cup-shaped, with an opening at a top end and, around the opening, a lip with a limit artifact. Wall-like structures can similarly have limit artifacts at their top end. If plating on a mold's side surface, the non-plateable surface can be the lower surface of an overhanging polymer disk or structure positioned on the mold. Plated tubes and wall-like structures can be employed in microfluidic structures.

Abstract: A method for casting a thick layer of photoresist material onto a substrate. The method including the steps of pressing the photoresist against the substrate material using a presser plate and limiting the travel of the presser plate by using spaces which can be positioned on the substrate material. The process further including the step of holding the presser plate in a pressed position while the photoresist is at least partially cured or solidified.
