View source notes and limits
The official page describes transducers, optional imaging features and sample analysis, not detection or cause-identification results for this attach stack.
Scope and limitations Air-defect thickness sensitivity differs from spatial resolution and is not a detection guarantee across stacks. An acoustic anomaly alone establishes neither cause nor complete three-dimensional geometry. What to prepare BLNKK suggests preparing the die/attach/substrate stack, target depth/region, coupling-medium restrictions, controls, existing images and sampling coordinates.

View source notes and limits
The 2023 brochure lists maxima of 225 kV and 450 W and a minimum 1 µm transmission-target focal spot, explicitly warning that all specifications cannot be achieved simultaneously. These are not CT defect-resolution figures.
Scope and limitations Minimum focal spot size does not establish the smallest detectable defect; voltage, power and spot size also depend on the target. Absorption, magnification and image noise affect results, so fine-pitch bump defect detection cannot be assumed. What to prepare BLNKK suggests preparing sample dimensions, material stacks, regions and defect sizes of interest, plus an acceptable scan time. Known-good and faulty specimens can help assess images and interpretation. Confirm with the supplier Confirm demonstrated sample image quality, defect acceptance criteria, target/detector configuration, and the included analysis, calibration and automation functions.
- Comet Yxlon · Cheetah EVO X-ray and laminography inspection for semiconductors ↗
View source notes and limits
The product page documents micro3Dslice laminography, CT, void analysis and semiconductor applications, and describes submicron detail recognition. These supplier descriptions do not establish detection yield or production throughput for a specific package.
Scope and limitations Visibility depends on materials, thickness, overlapping geometry and scan configuration. Submicron detail recognition is not a universal detectable-defect specification, and images alone do not establish joint strength or the cause of void formation. What to prepare BLNKK recommends bringing the package stack, joint materials and thicknesses, target defect locations/sizes, and reference and suspect samples. Include acceptable scan time and existing sectioning or imaging results to plan validation. Confirm with the supplier Confirm the X-ray tube, CT/laminography and VoidInspect configuration, then validate resolution, void criteria and radiation dose on samples.

View source notes and limits
The system page lists Class 10 cleanroom operation, multilayer inspection and defects including voids, delamination, inclusions and thickness variation. The SAM technology page explains coupling and depth/resolution tradeoffs; neither qualifies detection performance for a particular panel.
Scope and limitations Coupling, material attenuation, specimen thickness and interface depth affect visibility. Higher frequency does not ensure better detection of every deep defect, and acoustic contrast cannot directly establish joint strength. What to prepare BLNKK recommends preparing panel dimensions, the material stack, target interface depths and defect locations, plus reference and suspect samples. Include coupling-medium compatibility, acceptable scan time and available sectioning results. Confirm with the supplier Confirm holders, dimensions, transducer frequency, depth gating and supported scan modes, then validate interpretation on samples. Discuss coupling/drying, cleanroom requirements and automated data integration.
- Waygate Technologies · Phoenix V|tome|x S Neo dual-tube high-resolution industrial CT ↗
View source notes and limits
The manufacturer’s public information describes electronics inspection and configurable microfocus/nanofocus CT routes for S Neo. Equipment capability does not establish a void-detection guarantee for a particular package.

Confirm dual-tube, metrology and scan coverage against the current equipment configuration. What to prepare BLNKK suggests preparing attach material, thickness and surrounding stacks, suspected locations and void sizes, plus acceptable scan conditions. Known reference or cross-section data can help evaluate image interpretation.

The product page and Revision 2.3.0 flyer describe alignment, process logging and module options. The separate technical-data download was unavailable.
Scope and limitations Modules are configuration-dependent. Placement accuracy does not establish bonded accuracy or production throughput; optical observation does not inspect buried voids. What to prepare BLNKK recommends preparing die/substrate dimensions, fiducials, joining materials, presentation and target thermal/force histories. Plan post-bond alignment, void and strength checks. Confirm with the supplier Confirm modules, fixtures, atmosphere and manual/automatic operation scope. Request current accuracy definitions, thermal-expansion compensation and validated process-transfer conditions.

Fast-mode voxel counts do not replace full quantitative evaluation. Results need checks against reference specimens or complementary methods. What to prepare BLNKK suggests preparing voxel and actual resolution/contrast information, reconstruction/artifact conditions, bond-layer ROIs, segmentation settings, target defect sizes and reference cross-sections, while retaining version and workflow records. Confirm with the supplier Confirm edition/licensing, quantitative porosity and batch features, formats and computing resources, plus algorithm selection/validation for multi-material data.

What to prepare BLNKK suggests preparing the die/attach/substrate stack, target depth/region, coupling-medium restrictions, controls, existing images and sampling coordinates. Confirm with the supplier Confirm transducer, frequency, target interface/gates and required options. Trial the actual stack and correlate with cross-sections to establish accessible interfaces, detection limits and localization repeatability.

Nikon Industrial Metrology · XT H 225 ST 2x non-destructive 3D X-ray CT for advanced packages ↗Scope and limitations Minimum focal spot size does not establish the smallest detectable defect; voltage, power and spot size also depend on the target. Absorption, magnification and image noise affect results, so fine-pitch bump defect detection cannot be assumed. What to prepare BLNKK suggests preparing sample dimensions, material stacks, regions and defect sizes of interest, plus an acceptable scan time. Known-good and faulty specimens can help assess images and interpretation. Confirm with the supplier Confirm demonstrated sample image quality, defect acceptance criteria, target/detector configuration, and the included analysis, calibration and automation functions.
Comet Yxlon · Cheetah EVO X-ray and laminography inspection for semiconductors ↗Scope and limitations Visibility depends on materials, thickness, overlapping geometry and scan configuration.
