Latest Patents
William R. Bjorge holds a patent for a "Vertical spray etch reactor and method." This invention involves a unique process where a nitric acid etching solution is sprayed onto an upright workpiece in the form of low impact, large drops. This method produces a gentle sheeting flow of the etching solution down the workpiece. The solution is sprayed in a trapezoidal pattern, ensuring that the upper portion of the workpiece receives the majority of the solution. The etching solution is delivered to the spray nozzles by a low shear positive displacement pump. As the workpiece exits the etch chamber, it is sprayed with a solution to remove the etching solution and dissolved copper, while also adsorbing gaseous by-products from the etching reaction. The rinsing solution is collected and reused to replenish the etching solution, ensuring efficiency in the process.
