Abstract: To address the challenges of quantitatively assessing interlayer adhesion strength in green ceramic tapes during ceramic package manufacturing and the insufficient stability of bonding adhesives, this study proposes a tensile shear testing method for evaluating green ceramic adhesion. By designing specialized fixtures and specimen structures, the issues of sample deformation and non-uniform interfacial stress distribution inherent to green ceramic testing were resolved, enabling quantitative characterization of interlayer adhesion strength during processing. Additionally, the bonding adhesive formulation was optimized by incorporating a polar small-molecule compatibilizer, which significantly enhanced interlayer adhesion. Quantitative testing demonstrated that the optimized adhesive improved green ceramic adhesion strength by nearly threefold, effectively reducing delamination defects during both machining and high-temperature sintering. This research provides critical technical support for process quality control in ceramic packaging, contributing substantially to improved device hermeticity and long-term reliability.
