Wires Coating Thickness Measurement

Applications

Measurements on very small flat components and structures such as printed circuit boards, contacts or lead frames
Analysis of very thin coatings, e.g., gold/palladium coatings of 0.1 m (0.004 mils)
Measurement of functional coatings in the electronics and semiconductor industries
Determination of complex multi-coating systems
Automated measurements, e.g., in quality control

Features

The FISCHERSCOPE X-RAY XDV- is a universally applicable energy-dispersive x-ray measuring instrument. It is particularly well suited for non-destructive analyses and measurements of coating thicknesses on very small components and structures, even with complex coating systems.

Design

The FISCHERSCOPE X-RAY XDV- is designed as a user-friendly bench-top instrument. It is equipped with a high-precision, programmable XY-stage and an electrically driven Zaxis. The housing features a slot in the side allowing for the measurement of even large components, e.g., pc-boards. The sample stage moves into the loading position automatically, when the protective hood is opened. A laser pointer serves as a positioning aid and supports the quick alignment of the sample to be measured. A high-resolution color video camera simplifies the precise determination of the measurement spot.
