Printed circuit boards are plated with a high acid-low copper sulfate bath which uses a grain refining agent comprising the extract of regular coffee added in an amount of between 0.1 and 1.0 g/l of bath solution. The bath is operated at a plating current density of between 15 and 60 asf and a bath temperature in the range of 20 to 40 C.
The copper-laden organic solution is then separated from the leachate in a settling tank. Sulphuric acid is added to the pregnant organic mixture, which strips the copper into an electrolytic solution. The leachate, containing the iron and other impurities, is returned to the leaching operation where its acid is used for further leaching.
