Customer application: Determination of organic additives in acidic copper baths

Hoveddokument

AT&S is a leading producer of printed circuit boards. One of the most important process steps during their manufacture is the galvanic generation of thin copper layers. In order to ensure optimum copper deposition, organic additives are added to electroplating baths that must be present within narrow concentration ranges. CVS is used to check whether these concentration ranges are being maintained. Instruments from Metrohm are being used at AT&S for this purpose.
