Increasing Productivity and Reducing Waste with an Etching/Regeneration System

Abstract: Since joining PCMI in 1994, regeneration has been a recurrent topic. Everybody talks about it, almost all companies worldwide use it, and everybody thinks about it in a different way. It is quite simple to understand the interest in the topic, as it could allow us to etch using the same ferric chloride batch for a long time, without changing working parameters, and its stable quality fulfills at least 50% of our needs.
