COATING THICKNESS MEASUREMENT GAUGE FOR CONNECTORS : XDLM 237
Coating thickness measurement gauge for connectors - XDLM237 is engineered using best available techniques and following international industrial standard. These are X-ray fluorescence measuring instrument for manual or automated coating thickness measurements and analysis on PC-boards, electronics components and mass-produced parts, even on small structures. These are widely used for the measurement and analysis of thin coatings, even at small concentrations. These are acclaimed for its effective usage and longer service life. MODELSXDLM 231: Plane support stage, motor-driven Z-axis XDLM 232: Manually operable XY-stage, motor-driven Z-axis XDLM 237: Motor-driven XY-stage that moves into the loading position automatically, when the protective hood is opened. Motor-driven programmable Z-axis TYPICAL FIELDS OF APPLICATIONMeasurement of electroplated mass-produced parts Inspection of thin coatings, e.g., decorative chromium-plating Analysis of functional coatings in the electronics and semiconductor industries Automated measurements, e.g., on printed circuit boards General SpecificationIntended use:Energy dispersive X-ray fluorescence measuring instrument (EDXRF) to determine thin coatings and alloys.
