When coating metals, even the thinnest layers can achieve the desired functional effect. However, these layers must be applied uniformly to ensure optimal electrical performance and long-term stability. Any excess coating not only wastes valuable materials but also significantly increases costs.

The SnLAYER analysis system from ECH offers a fast and highly accurate solution for determining coating thickness on metallic surfaces – all with a single measurement.

Innovative Electrochemical Technology

SnLAYER is based on a newly developed electrochemical method using coulometric voltammetry, fully aligned with DIN 1787 and DIN 40500, Part 5.

The patented potential scan method enables the simultaneous detection of both free and alloyed portions of the coating – for example, tin layers on copper substrates.

Fast, Reliable Results

A typical analysis takes less than five minutes, delivering precise results that help optimize material usage, ensure quality, and reduce costs in production processes.
