JEDEC JESD22-B109 Die Bond Shear Testing
The JEDEC JESD22-B109 die bond shear test is a critical procedure in the semiconductor industry, aimed at ensuring the integrity and reliability of die bonding processes. This test evaluates the mechanical strength of the bond between the die and its carrier substrate, which is essential for the overall performance and longevity of integrated circuits (ICs). The test method specifies that a tensile force should be applied to the bond wire until it shears off at the die pad.
The significance of this test lies in its ability to identify potential weaknesses or flaws in the bonding process. A reliable bond is crucial for maintaining electrical connectivity and preventing issues such as poor thermal conductivity, which can lead to device failure. This testing ensures that the die is securely attached to the package, allowing it to withstand the mechanical stresses encountered during manufacturing, assembly, packaging, and end-use applications.
The test is conducted using specialized equipment designed to apply a controlled force along the bond wire in a direction parallel to the interface between the die and the package. This ensures that the failure occurs within the bond itself rather than at the interfaces with other components of the device or during handling. The methodology follows strict guidelines outlined in JEDEC Standard JESD22-B109, which provides detailed steps for performing the test, including specimen preparation, equipment calibration, and data interpretation.
For this service, we use cutting-edge instruments that comply with the latest standards. Our team of experts ensures that every step adheres to the specified criteria to deliver accurate results. The process begins by preparing the die and wire bond for testing according to the standard's requirements. This includes cleaning the surfaces, applying a consistent layer of adhesive if necessary, and ensuring proper alignment.
The test apparatus applies a precise force along the bond wire, typically between 100g and 300g, depending on the die size and type. The force is gradually increased until the bond shears off at the die pad. Once the shear occurs, the machine automatically records the load value and the distance traveled during the test.
The results are analyzed to determine if they meet the specified criteria for acceptable bond strength. If the bond fails outside of these parameters, it indicates a potential issue with the bonding process that may need addressing before further assembly or testing can proceed. This data is then reported in detail, providing valuable insights into the quality and reliability of the die bonding process.
Our service offers more than just compliance; it provides actionable intelligence to improve your manufacturing processes. By identifying weak points early on, you can prevent costly rework, ensure product consistency, and enhance customer satisfaction by delivering reliable products that meet or exceed industry standards.

In summary, JEDEC JESD22-B109 die bond shear testing is a cornerstone of semiconductor quality assurance. It ensures that the mechanical integrity of your products meets stringent requirements, thereby enhancing their reliability and performance in real-world applications.
Scope and Methodology
The scope of JEDEC JESD22-B109 die bond shear testing is broad but focused on ensuring the mechanical robustness of the bond between a semiconductor die and its carrier substrate. This service encompasses a range of methodologies aimed at evaluating the strength of these bonds, which are critical for the proper functioning of integrated circuits.
The methodology begins with specimen preparation, where the die and wire bond are cleaned thoroughly to remove any contaminants or residues that could affect the test results. Following this, the bond is aligned correctly within the testing fixture according to JEDEC standards. Calibration of the testing equipment ensures accurate force application during the shear test.
During the test, a controlled tensile force is applied along the bond wire until it shears off at the die pad. The load value and distance traveled are recorded automatically by the instrument for analysis. This data helps in determining whether the bond meets the required strength criteria as specified in the standard. If the bond fails outside these parameters, it suggests that there may be a problem with the bonding process.
The results of this testing serve multiple purposes. Primarily, they provide assurance to quality managers and compliance officers that the die bonding processes are reliable and consistent across production batches. R&D engineers can use this information to refine their designs and improve manufacturing techniques. For procurement teams, it offers a means of validating supplier performance against established benchmarks.
