TROUBLESHOOTING PLATING ON PLASTICS
Although the electroless copper plating systems are similar to those used in printed circuit processing, electroless nickel processes differ greatly from those used in metal plating and are not interchangeable. Room temperature nickel solutions are mildly alkaline and give a low and uniform deposition rate. At present, automotive and other
