Abstract :
In this paper we have written about our work of XRF (X-ray fluorescence) analysis. With this non-destructive testing it is possible to analyze the composition of a certain material. While examining different materials we have concluded that some manufacturers have not complied their products with the RoHS directives even after more than a year. After observing printed wiring boards (PWB), components and solders, sometimes we found amounts of restricted materials even 10 to 50 times above the limit. In our experiments we realized that not just the components, even the working tools have to comply with RoHS in order not to contaminate the experiments.
