Is void area percentage sufficient for this product's acceptance decision, or are three-dimensional distribution and paired thermal tests needed?

Provide images and thermal boundaries for the same sample first, to establish whether three-dimensional quantification adds decision-relevant information.

Problem context and interpretation

Compiled by BLNKK from public sources

Solder or conductive-adhesive die-attach thermal paths with confirmed voids

  • Co-registered 2D/3D images and segmentation uncertainty
  • Bond-layer thickness, heat-source distribution and material thermal parameters
  • Thermal tests at the same power and cooling boundaries with a known-good control
Technical Q&A awaiting input
  • Is void area percentage sufficient for this product's acceptance decision, or are three-dimensional distribution and paired thermal tests needed?
  • Compare two-dimensional projections and three-dimensional void distributions for the same sample
  • Compare modeled and measured results at fixed thermal boundaries, then establish product-specific risk criteria
