Advanced Mixed-Mode Bender

Embark on a transformative journey in material testing with the NANOTEST Advanced-Mixed-Mode Bending (AMB) Testing Device. As a preeminent provider of cutting-edge solutions in materials science, we have pioneered a revolutionary method to comprehensively grasp and enhance the reliability of material interfaces.

For materials scientists, the AMB testing device offers a unique combination of experimental and numerical fracture mechanics approaches. This enables the precise determination of critical energy release rates under various conditions such as mode-mixity and temperature. Our solution provides an essential foundation for correctly interpreting finite element results and helps you understand the causes of crack initiation and propagation like never before.

But it's not just invaluable for research purposes. It also opens up new possibilities for material manufacturers and product producers. Our technology allows for accurate and rapid evaluations of interface properties, leading to realistic measurements on real package interfaces under real process parameters. The result? The highest possible product quality in the shortest time and with minimal use of specimens.

Off the package, into the tester

Realistic material characterization

NANOTEST has pioneered the development of the Advanced-Mixed-Mode Bending (AMB) Testing Device, ensuring precise and rapid evaluation of interface properties.

Accurate mixed-mode fracture mechanical data is imperative for successful reliability design. Particularly for interfaces, obtaining fracture toughness data can be challenging, given its dependence on processing conditions, loading angles, moisture levels, temperatures, and loading rates.

The AMB tester stands out as the sole testing equipment capable of consistently handling small samples, such as those directly cut from the package itself, without the need for gluing or clamping. To eliminate transfer effects, the tester interacts with the sample solely through compression. This approach necessitates only two samples to characterize each angular branch of the energy release rate curve, thus maximizing the utility of available samples.

Key Features:

  • Device designed to test mixed-mode adhesion strength of bi-material interfaces
  • Specimen-centered design accommodates artificial and product-origin samples
  • Two independent actuators cover a broad range of mode-mixity in a single test
  • Optical observation facilitates monitoring delamination progress during tests
  • Crack tip detection enabled by Digital Image Correlation (DIC)
  • Finite Element calculations derive critical energy release rates using test parameters and loading data

Advantages of AMB

  • Direct use of specimens from the production line, including package-sized samples, ensuring 100% process representation
  • Significantly reduced measurement time compared to alternative methods
  • Ability to generate a Gc (ψ) curve with a minimum of two specimens
  • Standardizes fracture mechanics as a fundamental tool in system design
