摘　　要：随着航天产品研制不断趋于轻量化、小型化发展,传统结构组成的变压器将逐步被更具优势的平面变压器替代。在环境应用过程中,平面变压器中磁芯、胶黏剂以及FR4印制板等材料热膨胀系数的差异将导致热应力的产生,显著影响产品组件的可靠性。本研究工作针对平面变压器组件中关键粘接环节开展深入研究,通过COMSOL仿真和高低温冲击环境验证,确认最佳的磁芯粘接方式,为后续平面变压器可靠应用提供数据支撑。With the continous development of aerospace products towards lightweight and miniaturization,tranditional structural transformers will gradually be replaced by planar transformers with superior advantages.In practical applications,differences in coefficients of thermal expansion(CTE)among materials such as magnetic cores,adhesives and FR4 printed circuit boards in planar transformers generate the thermal stress,significantly affecting the reliability of products.This study focuses on the critical bonding process during the fabrication of planar transformer assemblies.Through COMSOL simulations and thermal shock environment tests,the optimal magnetic cores bonding menthod was confirmed,providing data support for subsequent reliable applications fo planar transformers.
