Our process etchant control doesn have monitor and alarm functions. What are we missing?
Without continuous process monitoring your first indication of chemistry problems is likely to be a scrap board coming out of the machine. At this point there may already be eight more already etched boards behind it in the etcher. This can be very expensive. This means up to 4600 square inches of boards have been ruined if an alert operator catches the first bad board that comes out. At the final etch stage of the process boards have from $0.10 to $1.00 per square inch invested in them. This can be a very expensive way to detect chemistry problems.
