The microscopic DIC measurement system provides standardized testing solutions covering the entire chain—from chip design and packaging processes to reliability verification and failure analysis. It is suitable for the quantitative analysis of dynamic thermal warpage at the micron scale in advanced packaging, supporting yield improvements and technological iteration within the domestic advanced packaging industry.

Microscopic DIC measurement technology is employed to measure thermal warpage and deformation in chips. Thanks to key advantages—such as non-contact operation, sub-micron precision, full-dimensional data output, and stability across the entire temperature range—it has become the standardized technical approach for the quantitative inspection of thermal warpage, thermal deformation, and thermal stress. Representative equipment, such as the XTOP3D XTDIC-MICRO microscopic DIC system, comprehensively addresses inspection needs across the entire value chain, including chip R&D, packaging processes, reliability verification, and failure analysis.

A microscopic DIC measurement system is employed to conduct thermal deformation and warpage testing on chips subjected to full-range temperature cycling. This process fully replicates deformation dynamics across the heating, soaking, and cooling stages of reflow soldering and precisely quantifies warpage values ​​at various temperature points, enabling the optimization of mold compound formulations and reflow heating profiles to ensure high chip packaging yields.

Standard DIC measurement systems lack optical magnification lenses, relying instead on wide-field-of-view lenses to measure wafers and large PCBs. In contrast, microscopic DIC systems utilize a stereo microscope to narrow the effective measurement field of view to 1–10 mm; they incorporate specialized microscopic calibration algorithms, extended depth-of-field compensation, and anti-frost systems (for thermal cycling) to specifically overcome optical interference challenges when measuring the deformation of microchips under high and low temperatures.

The XTOP3D microscopic DIC measurement system comprises three core modules—a microscopic binocular DIC measurement unit, a stereo microscope, and a programmable high/low-temperature stage. Specifically designed for a 1–10 mm field of view (suitable for micro-chips), it enables the simultaneous measurement of 3D full-field warpage, displacement, strain, and CTE across various temperature ranges.

For a modern, comprehensive laboratory, the combination of extensometers, strain gauges, and DIC equipment represents the optimal configuration: extensometers handle standardized routine tests, strain gauges manage long-term, fixed-point monitoring, and 3D DIC strain measurement systems tackle high-difficulty testing—such as that involving complex materials, cutting-edge research, and failure analysis. By combining these tools according to specific needs, the setup comprehensively covers all strain measurement requirements.

Digital Image Correlation (DIC) technology has become a standard tool in the mechanics research of composite materials.

Selecting professional DIC equipment helps overcome challenges in composite material testing and facilitates technological upgrades within the industry.

Strain Measurement Selection Guide: As the limitations of strain gauges and extensometers become increasingly apparent in the mechanical testing of composite materials, 3D full-field strain measurement systems based on Digital Image Correlation (DIC) have emerged as essential equipment for analyzing damage evolution, characterizing mechanical properties, and optimizing structural design.

High-temperature experimental setups integrating Micro-Digital Image Correlation (Micro-DIC) technology with temperature-controlled chambers (heating/cooling stages) have become a key method for revealing the microscopic thermo-mechanical behavior of materials, thanks to advantages such as non-contact measurement, full-field analysis, and high resolution. Using the XTOP3D XTDIC-MICRO system as a case study, this article provides a detailed analysis of the principles, workflow, key technical challenges, and typical applications of this experimental technique.

The microscopic DIC strain measurement system enables real-time monitoring of chip deformation behavior under temperature changes at the micro-scale, providing precise data support for thermal design and reliability assessment.

Materials at small scales exhibit significant size effects—meaning that properties such as strength, plasticity, and fracture toughness differ from those observed at the macro scale. Thanks to their high spatial resolution and non-contact, full-field measurement capabilities, microscopic DIC systems have become ideal tools for investigating the mechanical properties of small-scale materials.

With the advancement of materials science, micro-electromechanical systems (MEMS), and biomedical engineering, increasingly stringent demands have been placed on the measurement of deformation and strain at the micro-scale. Thanks to advantages such as non-contact operation, high precision, and full-field measurement capabilities, the Digital Image Correlation (DIC) micro-strain measurement system is becoming an essential tool in both laboratory settings and industrial inspection.
