Electroless Bath Automatic Analyzers from a User's Viewpoint

Seven years of production floor use of automatic analyzers developed by Photocircuits has proven their effectiveness in controlling the metal deposition processes in additive and substractive printed board manufacturing with a minimum of operator intervention. The control capabilities include continuous chemical analysis and adjustment of the additions to the plating baths. Use of analysers has eliminated the discrepancies caused by the time lapse between the periodic manual analyses, variations in workloads, and chemical addition rates. Continuous display and permanent recording of main bath parameters facilitate the bath maintenance and troubleshooting. The alarms, when incorporated in the system, aid the operators in locating problems occurring beyond the scope of the automatic analyzers' control.
