X-RAY TECHNOLOGY FOR THIN COATINGS.

After a brief explanation of the X-ray fluorescence (XRF) principle, the article describes the Fluoroderm XRF-100 measuring equipment that has been recently introduced to the market. Using the latest X-ray equipment technology, the instrument is designed to measure extremely thin coatings on flat, irregular or multilayer parts such as flat packs, tips of lead frames, bifurcated contacts, printed circuit boards and jewelery. Areas as small as 0. 3mm diameter can be measured using the built-in microscope and x-y-z positioning stage. As the sample is not contacted, even delicate components are safe from damage.
