JXA-iHP200F WDS analysis of joint cross sections
JEOL · Packaging processes and engineering validation
- Purpose
- Compare elemental composition at selected solder-fracture cross-section locations against cracks and unaffected regions.
- Technical approach
- A field-emission electron probe generates X-rays for WDS analysis, supported by SEM/EDS observations and agreed standards/conditions.
- Scope of use
- Assess prepared accessible sections, vacuum compatibility, layer thickness and possible neighboring-layer contributions.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsWDS composition alone establishes neither phase nor cause. Thin-layer signals may include neighboring material; beam/image dimensions are not automatically the effective analytical sampling scale.
What to prepareBLNKK suggests preparing failed/control locations, stack materials, thickness estimates, preparation history and SEM/EDS data. Define elements and regions before discussing standards and quantification.
Confirm with the supplierConfirm current/voltage, standards/corrections, background and layer contributions, and detection-limit checks. Agree on complementary methods and inference limits if phase or cause identification is required.
- Public evidence
- JEOL documents integrated WDS/EDS analysis, not sample-specific quantitative error or a validated fracture cause.
