XTOP3D’s semiconductor thermal deformation and warpage measurement solution utilizes the high-precision XTDIC-MICRO 3D Microstrain system integrated with stereo microscopy. Designed for advanced chip packaging, PCBs, and single-crystal silicon, this non-contact DIC (Digital Image Correlation) technology provides real-time, full-field 3D strain and out-of-plane displacement analysis. It accurately evaluates CTE (Coefficient of Thermal Expansion) mismatch, solder joint reliability, and thermal warpage from micro-scale to full assemblies under varying temperature loads.

  • Application Cases
    • DIC Full-Field Measurement Solution for Chip Warpage and Thermal Deformation
      XTOP3D's full-field deformation measurement DIC technology acquires baseline profile data, tracks displacement data of identical points under varying temperature loads, and calculates and analyzes strain data. This allows for simultaneous analysis of chip warpage, soldering process evaluation, and strain concentration between different cross-section materials. CTE measurement can further identify chip thermal warpage and CTE mismatch issues.
    • Microscopic DIC technology for single crystal silicon thermal expansion warpage CTE measurement
      The thermal warpage experiment uses the Xintuo 3D XTDIC-MICRO microscopic strain measurement system and temperature controller (temperature control ±0.1°C). Based on microscopic DIC technology, a chip thermal warpage measurement platform is built to carry out thermal warpage tests on typical stacked structures, realizing real-time observation of thermal warpage of multilayer boards during heating.
    • DIC 3D Strain Measurement System Solution for Wafer Thermal Warpage and Deformation Measurement
      During semiconductor manufacturing and chip packaging, thermal warpage in wafers is a critical factor leading to issues such as chip cracking, open solder joints, circuit shorts, device performance drift, and even total system failure. Leveraging the advantages of non-contact, full-field, and micron-level measurement, Digital Image Correlation (DIC) technology—specifically 3D strain measurement systems—can capture comprehensive data on 3D warpage morphology, displacement fields, and strain fields across the entire temperature range. This provides a quantitative basis for optimizing wafer processes, designing for thermal matching in packaging, and validating the reliability of automotive-grade chips.
