X-Ray Fluorescence (XRF) Measuring Systems for PCB Testing

Specific X-ray Fluorescence Measuring Instruments (XRF) for Measurements and Analyses of Coating Thicknesses and Compositions on Printed Circuit Boards

All instruments have a gap in the housing and a large sample stage. This allows for measurements on large PCB multi-panels up to 610 x 610 mm (24 x 24 in). The XULM^®-PCB und XDLM^®-PCB 200 instruments can be equipped with a sample stage extension to measure even larger PCBs or multi-panels.

• Robust entry-level instrument with a fixed aperture and one fixed filter, micro-focus X-ray tube, proportional counter tube as X-ray detector and fixed sample stage
• Option: sample stage extension to enlarge the usable sample placement area to 1200 x 630 mm (47 x 24 in)
• Measuring direction bottom up, this allows for quick and easy sample positioning

Typical fields of applications

• Measurements of functional coatings in the electronics and semiconductor industries
• Determining of the composition of electroplating baths
