Coating Thickness measurement of lead frames using XRF

Coating thickness measurements on lead frames with XRF has established itself as the measurement method of choice as the electronics industry makes use of ever thinner coatings, demanding measuring technologies to provide reliable parameters for product monitoring and control. The coating system Au/Pd/Ni is frequently used in the electroplating of lead frames, with CuFe2 (CDA 195) as the substrate material. Typical coating thicknesses are between 3-10 nm Au and 10-100 nm Pd. To see how the FISCHERSCOPE® X-RAY XDV®-SDD X-ray fluorescence instruments monitor the quality of these coating systems, follow the link below to the page and application note on coating thickness measurements on lead frames
