Abstract

The efficiency of the acid cleaning process is critical in ensuring optimum quality at an electroplating facility. This efficiency depends on various variables including the operating temperature, acid/inhibitor concentration, rate of contamination etc. Dumping of acid solutions is a frequent occurrence at electroplating facilities. In most instances the remaining usable lifespan of the acid is unknown. It would be ideal to predict the actual rate of cleaning and contamination of the acid solution. This would be useful in predicting acid dosing, acid lifespan and acid efficiency. A major consideration to this problem is the uncertainties associated with the variables for the acid usage. These include changes in operations, changes in temperature, concentration changes, contaminant changes etc. In this study a model is developed that predicts the acid consumption whilst allowing for all operational uncertainties. A comparison is presented on the results of this model and existing plant data. This model finds further application in predicting the production rate of metal through an electroplating facility. A Mathlab Case study on this application is presented.
