Method to extend the bathlife of alkaline accelerator solutions |
摘要 |
This invention is a method to extend the bath life of certain alkaline accelerators used in metal/tin colloid catalyst used in direct plating processes on printed circuit boards. The method is comprised of the following steps: measuring the pH of the alkaline activator bath, and restoring, the pH of the alkaline activator bath to a desired pH range between 12.2 and 12.6.
