| Foresite now has the
capability to analyze lead free processed assemblies for RoHS
directive compliance utilizing XRF (X-ray Fluorescence) analysis.
Utilizing a Fischerscope XRF XDAL system, Foresite can examine
assemblies with 0.2 mm focal distance. This system is capable of
performing both quantitative elemental analysis and thickness
measurements in an integrated fashion. It is able to examine each
component on an assembly individually through a small spot analysis
method. Looking at each layer individually, our XRF XDAL system is
able to provide a meaningful and accurate measure of the RoHS
compliancy of a product. System
Specifications
• X-ray tube with adjustable high voltage: 10; 30; 50kV
• Measures in element range Z=13 (Al) to Z=92 (U)
• Large, high energy resolution & programmable XYZ-stage
• Interior Dimensions: 460 mm W; 500 mm D; 146 mm H
• Four Collimators
• 0.2mm minimum size of measuring spot
• 0-20mm usable focal range
• Autofocusing
• Video microscope with up to 184x magnification
Applications of XRF Analysis
• Quantitative analysis of solid, powder or paste-like materials as
well as liquids
• Thickness & element composition measurements of individual
coatings in coating systems with up to 24 different elements
• Substrate materials analysis through coating systems
Advantages of XRF Analysis
• Non-destructive analysis method
• Analyzes small solder joints
• Focal distance of .2mm spot analysis
• Able to differentiate layer thickness
• With known stack-up structure, we are able to program system to
examine each layer
• Automated system to look at one joint of every component to ensure
RoHS compliance
• System designed to exclude interval leaded constituents and does
not include the interfacial aspects of the components, but only the
external solder surfaces, joint and board layers
Follow-up Verification
If you would prefer to verify the results of XRF analysis, Foresite
can provide cross sectional or SEM / EDX analysis (*note: cross
sectioning & SEM / EDX are destructional testing methods).
