90 PCB007 MAGAZINE I SEPTEMBER 2024 for that controller (and a close-up photo of it in operation) using the spectrophotometer and pH probes. Also illustrated is the laboratory R&D copper electroplating set-up that uti- lized six of the sensors that I've talked about: Specific gravity, pH, conductivity, ampere- hour, electrochemical CVS, and spectropho- tometric. Figure 8: The electroless copper controller was a particular focus while I was a PCB process engineer. This is the process schematic and photo of the unit. The second illustrates a copper electroplating analyzer (using six basic sensors) and controller for laboratory research.
