VIC-3D full-field 3D deformation and strain measurement
Correlated Solutions · Warpage, topography and stress metrology
- Purpose
- Thermal or mechanical loading can produce nonuniform deformation on package surfaces and material coupons. This system measures visible-surface 3D displacement and strain distributions to support deformation comparisons and model validation.
- Technical approach
- Stereo digital image correlation tracks a surface speckle pattern and uses camera calibration to reconstruct 3D shape, displacement and strain. Measurements can be compared with finite-element results; deriving stress from strain still requires a material model.
- Scope of use
- Potential evaluations include visible package/substrate surfaces and material coupons under load. The specifications require Blue Falcon or Stereo-Microscope configurations for fields of view below 6 mm; thermal-window and temperature synchronization arrangements need confirmation.
- 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 limitationsSpeckle quality, field of view, calibration and optical access affect results; obscured regions and buried interfaces are not directly observed. Stress or lifetime interpretation requires additional models and validation.
What to prepareBLNKK recommends bringing specimen dimensions, regions of interest, expected displacement, loading histories and acceptable surface-pattern methods. Include thermal-window/fixture arrangements, temperature data and model outputs to plan synchronized comparisons.
Confirm with the supplierConfirm camera, optics and speckle suitability for the target field of view, then validate spatial resolution, strain uncertainty and acquisition rate on specimens. For thermal testing, discuss windows, temperature synchronization, calibration stability and data export.
- Public evidence
- The product page and system specifications document full-field shape, three displacement components, strain and correlation uncertainty. Camera configurations differ, and resolution depends on field of view; this is not a validated measurement specification for a customer package.
