Latest Patents

One of Decesare's latest patents is titled "Complex waveform for electrolytic plating." This method focuses on copper electroplating in the manufacture of printed circuit boards. It is specifically designed for filling through-holes and blind micro-vias with copper. The process involves preparing an electronic substrate, forming through-holes or micro-vias, and electroplating copper using a complex waveform that includes pulse reverse plating, DC plating, and synchronous pulse plating. This innovative approach ensures that the filling of through-holes and micro-vias occurs without defects.

Another significant patent is the "Single step electrolytic method of filling through holes in printed circuit boards and other substrates." This method also pertains to copper electroplating and includes similar steps as the previous patent. The acid copper electroplating solution used in this method comprises a source of copper ions, sulfuric acid, chloride ions, a brightener, a wetter, and a leveler. This solution effectively plates the through-holes and micro-vias until complete metallization is achieved.
