With a total of 5 patents to his name, Rhodenizer has made significant advancements that enhance the manufacturing processes of electronic components.
Latest Patents
One of Rhodenizer's latest patents is a method for the manufacture of printed circuit boards. This innovative process involves applying an alkaline strippable resist to the board material in a predetermined pattern. Following this, a catalytic material is applied, and the board is treated with an aqueous alkaline solution to remove the catalytic material from the resist surfaces without affecting the catalyst in non-resist areas. This method allows for a streamlined manufacturing process, enabling the activation and metallization steps to proceed without interruption for resist application.
Another significant patent involves an improved activation composition for preparing substrates for metallization in an electroless plating bath. This process enhances the activation of substrates prior to metallization, utilizing an organic acid in the activating bath. The preferred compositions include palladium halide ions and stannous halide ions, which provide a catalytic surface and protective sol, respectively. This innovation eliminates the need for a typical acceleration step while ensuring high-quality results, particularly for substrates with through holes, such as printed circuit boards requiring copper plating.
