  • Patent number: 5498311
    Abstract: A method for manufacture of printed circuit boards uses plasma etch back/desmear, carbon deposits on board surfaces to be plated and panel plating. The plated board is abrasively pre-treated, imaged, developed, etched, and stripped for final preparation before drilling. The pre-treating, imaging, developing, etch back and stripping used for inner panel boards is the same as the process steps and equipment used for the final process of the panel plated boards. The process is environmentally conscious in that it produces waste products which contain only one metal in solutions easily treated by conventional and non-conventional waste treatment technologies and eliminates or reuses by-products produced by other printed circuit board and produces waste products which contain only one metal.
