ELECTRODEPOSITION; ELECTROPLATING; ELECTROLYSIS.
Knowledgeable of a whole range of electroplating materials and processes, having written numerous papers and several Books. Worked with plating of gold, silver, cobalt, nickel (including sulfamate nickel, nickel sulfate (Watts) Woods and Sulfamate nickel strikes, bright, leveling nickel and special nickel processes. Familiar with Copper plating from cyanide, acid and pyrophosphate solutions, along with sulfonic, sulfuric and fluoboric acid processes for copper, tin lead, and alloys of various metals. Experience in cadmium, zinc, brass and bronze plating. Can answer questions on cleaning, activating and surface preparation and conditioning processes.

PLASTICS PLATING.
Knowledgeable in the preparatory steps, including cleaning, etching, conditioning and sensitizing and catalysts, for electroless plating of nickel and copper on plastic substrates and electroplating of plastics. Co-authored a book on plating of ABS plastic.

PRINTED-WIRING (Circuit) BOARD PROCESSES.
Experience includes preparation for and plating of printed-wiring boards, including through hole and surface mount boards as well as flex, multi layer and molded circuits. Designed processes and equipment for the manufacture of printed circuit boards of all types. Analyzed process and plating chemicals for maintenance of the solutions. Did research and supervised research and development of process chemicals and plating solutions for printed circuits, including multi-layered bonding chemicals. As a consultant, advised printed circuit manufacturers as to type of preparation chemicals, plating chemicals, equipment and process sequence design. Wrote chapter 9 of Electronic Materials and Processes Handbook Published by McGraw Hill.

DIRECT ELECTROPLATING.
Experienced in the use of process cycles and chemistry for direct plating of through-hole printed circuits, including both theory and practice of direct electroplating

MCM-C and MCM-L (MULTICHP MODULES).
Experience in processes for plating MCM's, including patents in this field.

CLEANING OF MATERIALS FOR PLATING.
Experience Including formulation, cleaning of leaded alloys, steel alloys, copper alloys, acid, alkaline and solvent processes.

ELECTROGALVANIZING AND OTHER CONTINUOUS STRIP STEEL PLATING.
Involvement in continuous plating as practiced in steel mills for zinc, nickel, copper brass and bronze.

ADVANCED TECHNOLOGY IN THE USE OF ELECTRO-LESS NICKEL FOR ELECTRONICS AND PRINTED CIRCUITS
New uses for specialty electro-less nickel processes are discussed, these uses include plating of printed circuit boards to allow direct mounting of components such as inc. Chips, plating of ceramic circuits, and through hole and overall plating of printed circuit boards. Download our complete document here

AUTOCATALYTIC ALLOY PLATING PROCESSES
Electroless (autocatalytic) plating processes can greatly increase the storage capacity of memory discs used in Winchester-type disk drives. A non¬magnetic electroless nickel layer is deposited onto a carefully prepared aluminum substrate, polished to a near perfect finish, activated, and plated with an electroless cobalt-phosphorus alloy.

ELECTROLESS NICKEL AND COBALT FOR MEMORY DISCS
Computers use different types of memory discs to store information. Today's surface technologies for producing these discs will be discussed with emphasis on thin film memory discs. Download our complete document here

PLATING OF ABS PLASTIC
There are several grades of ABS plastics. But only one platable grade (In the early days it was Cycolac EP 3510) There are now a number of suppliers of plating grade ABS. I do not know the new designations. Therefore if you specify Platable grade of ABS you are likely to get the correct product. Download our complete document here
