PRINTED CIRCUIT BOARD (PCB) AND PRINTED WIRING BOARD (PWB) FABRICATION; PLATING; ELECTROPLATING; WET PROCESSING. Expert has spent much of his past and present career involved in problem solving, R & D, and process development in the area of wet processing. This has included surface cleaning, etching, electroless plating (copper, nickel, tin, gold), and electrolytic plating (copper, nickel, solder, gold). His recent work includes process startup and characterization for a major microwave circuit board manufacturer. LAMINATES. Expert's work with PCBs includes familiarity with the materials aspects of various laminates used in conventional, flex, and microwave circuitry. In addition, he is familiar with various types of copper and other foil claddings. METAL FINISHING; METAL SURFACE EVALUATION; DECORATIVE COATING. Expert is experienced in the area of surface preparation and finishes for decorative and engineering purposes. This includes electroplating with copper, nickel, and gold as well as electroless plating with copper, nickel, tin, gold, and oxides. PLATING TRAINING. Expert has conducted training programs for both electroplating and electroless plating. These were custom tailored to specific groups such as research technicians with non-technical college degrees, mechanical and electrical engineers, and production platers with very little education. BRIGHT AND INTEGRAL ANODIZING PROCESSES; LITHOGRAPHIC PRINTING PLATE. A substantial portion of Expert's career has involved anodizing. This includes bright anodizing for automotive trim, color anodizing, and integral color anodizing for architecture. He has also done considerable work on anodic treatments for aluminum lithographic printing plates, which involved continuous coil anodizing. CONVERSION COATINGS; CHROMATE TREATMENT. Expert has experience in the application of various conversion coatings such as chromates, phosphates, silicates, and oxides. These have been applied to aluminum for corrosion protection and as adhesion enhancement for subsequent organic coatings. He has also worked with copper oxide treatments for PCB inner layer bonding.

| Selected Consulting Examples: |
-
Expert was asked to solve an etching and plating problem at a flex circuit manufacturer. The problems were very thin shorts between lines (unetched out copper) and unplated areas on lines in subsequent nickel / gold plating. Many defect parts were examined by microscope.Time was spent going through the manufacturing steps in production. Samples were pulled at each step. Subsequent examination by microscope indicated these problems were caused by residue of unremoved photoresist.The problem was traced to the photoresist stripper which was found to have a faulty filter. It was leaving some tiny fragments of photoresist film in the solution and these would on occasion redeposit on the work.
-
Expert was asked to help a microwave circuit board shop that was unable to ship their product for a few weeks due to high rejects from their heavy deposition electroless line. They wanted to change to a low deposition electroless copper followed by electroplated copper. They wanted to do some experimental work first to make sure it would be successful. Expert's work involved setting up the new process in an unused prototype line and running samples for them using the new method. This worked out well and a change over was made on the production line. A subsequent visit was made to define a window of operation using the small experimental line. In this work, the concentration of electroless copper bath components were varied, as well as temperature and time.
-
He was asked to help a company that manufactures packaging machinery to evaluate the feasibility of setting up captive anodizing and electroless nickel lines. An onsite visit was made to see the sizes of parts and numbers of parts that had to be processed, as well what sort of production rate would be needed. There was also the question of availability of adequate space, which they happened to have. Information was provided to them explaining each process, what chemicals were involved, and what companies sold them. Equipment was sized based on part size, number, and volume. Both lines were laid out indicating sequence and what equipment was needed for each process tank. Suppliers and prices were supplied. The general environmental regulations were spelled out and the appropriate local agencies and individuals were identified. After doing the above, they were put in touch with an engineering company that would actually do the installation.
-
Expert was asked to help a research organization speed up copper plating in blind vias that were bottomed out on a lower copper layer. This was an array of vias and was taking a very long time to plate (hours). The part was not very large so the concepts used in high-speed strip plating were applied and a demonstration experiment in their laboratory showed how it could be reduced to the order of several minutes. This involved design of a special cell as well.
-
Help was requested by a small manufacturer who had a captive nickel plating operation. They had periodic bouts of pitting and blistering. At their site, defects were examined and the day was spent with the production people so the process could be followed. After this, recommendations were made with respect to using adequate rinsing after electrocleaning, better agitation filtering, and temperature control on the nickel bath. Information was provided on some simple chemical analysis kits they could use.

Expert was asked to transfer technology that he had worked on subsequent to retiring. This technology had been sold to a French electronics company. The technology concerned a different method of electroless plating on PTFE substrates. This took two weeks at their pilot plant. It involved working with the French engineers and production people and helping them get started while they went through the process and producing samples for evaluations.
