TF-132A FILTRATION OF ELECTROLESS SOLUTIONS
www.sat-eng.comTF-132A FILTRATION OF ELECTROLESS SOLUTIONS Electroless plating solutions are used to deposit metals such as copper and nickel by means of chemical ... The filtration of electroless nickel solutions removes nickel phosphite, which is a by-product of the plating process. Since its solubility is lower in hot solution than
TF-131A FILTRATION OF NICKEL SOLUTIONS
www.sat-eng.comThe nickel-iron plating baths must be filtered and purified like any other bright nickel solution. Electrolytic purification by "dummy" plating to remove undesirable metallic impurities, such as copper, ... FILTRATION OF NICKEL SOLUTIONS (cont'd) Filtration systems from small laboratory sized
Treatment and Disposal of Spent Electroless Nickel Plating ...
www.plateworld.comNickel Solutions Referring to table II, all the same treating processes used for waste treating rinse waters can and are being used for treating electroless nickel plating solutions. The difference is the amount of materials to handle, high concentration of all the materials in the solution and most importantly the chelators (complexing agents) and
Chapter 3 Troubleshooting Electroless Nickel Plating Solutions
www.casf.caElectroless nickel solutions should have constant filtration to eliminate any particulate bath impurities such as dust, sand, or loose maskant material. With proper filtration (210 turnovedhr at 5 pm or less), roughness of the final deposit can be greatly reduced or even eliminated.

www.plateworld.comiron hydroxide, if any, will be picked up on the filter. A sulfamate nickel solution will dissolve iron, but it will precipitate as iron hydroxide at pH 4
TROUBLESHOOTING PLATING ON PLASTICS
www.plateworld.comAlthough 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
