AT&S Leoben, Austria: analytical process control using CVS

The Austrian company AT&S (Austria Technologie & Systemtechnik AG) with its headquarters in Vienna is one of the most advanced producers of printed circuit boards (PCBs) in the world. AT&S is perfectly positioned in the high-tech segment of HDI Microvia technology, which is primarily used in handheld applications (e.g. in cell phones, PDAs, etc.). Further important areas of activity are PCBs for automobiles and for industrial and medical uses.

Determination of organic additives in acidic copper baths

One of the most important process steps in the production of PCBs is the galvanic deposition of very thin copper coatings. In order to achieve a copper coating (deposit) of uniformly high quality, strict analytical control of the copper bath constituents is essential.

A company guaranteeing the highest product quality, innovative solutions, absolute customer loyalty and the best service has the right to demand the same from its suppliers. This is why the quality management of the Austrian company has relied on Metrohm instruments since 1988. They manage a large part of the workload and perform about 30 000 individual analyses per month.
