Scope

Scope: This document specifies the test method for the shear strength of micro-nano metal sintered connectors. This document is applicable to the determination of the shear strength of micro-nano metal sintered connectors and the judgment of failure modes (if any occur), and is used for the test evaluation of micro-nano metal materials and practitioners in related fields; Main technical content: Metal interconnect materials play a key role in the semiconductor packaging industry. Traditional packaging uses solder alloy interconnects, but the precipitated intermetallic compounds lead to low service temperature and high brittleness of the interconnect layer. As one of the most suitable interface connection technologies for the packaging of third-generation semiconductor modules, novel micro-nano silver and micro-nano copper-based sintered interconnect technologies have the advantages of single component, low process temperature, and high service temperature, and the reliability of chip connectors can also be greatly improved. Shear strength, as one of the main performance indicators of micro-nano metal sintered connectors, has received widespread attention. Since micro-nano metal sintering technology is still in the stage of technology promotion, the industry has not yet developed a dedicated standard for shear strength testing methods for sintered connectors prepared using this technology. The shear strength of traditional solder is low, and its test method standards and strength judgment rules are no longer applicable. At the same time, due to the different test instrument models, sample specifications, test conditions, and operating steps used by various units in the industry, it is difficult for practitioners in the industry to compare the shear strength performance of micro-nano metal sintered connectors under unified conditions. It is hoped that the formulation of this standard will effectively standardize the testing methods in the industry, enable effective co
