摘要: 制造与装配过程的翘曲问题是应用无芯基板最大的挑战之一,其主要原因是不同材料间热机械性能不匹配所造成的。介绍了一种3层无芯基板的制造过程,并利用有限元软件ABAQUS6.10对该过程进行了模拟。通过对模拟结果与实验测试结果的对比,再对翘曲变形的机理进行分析,对比了不同因素对翘曲变形大小的影响,对减少翘曲变形给出了有效的工艺设计建议。

关键词: 无芯基板, 翘曲, ABAQUS

Abstract: Due to the fact that the thermomechanical properties of the different materials do not match,the warpage during the manufacturing and assembly process is one of the biggest challenges in applying the coreless substrate.In the paper,a manufacturing process of a coreless substrate is introduced.The process is simulated by the finite element software ABAQUS6.10.The influence of different factors on the warpage is analyzed by analyzing the simulation results and the mechanism of warping deformation,and the helpful suggestionhasbeengiventoreduce the warpage.

Key words: coreless substrate, warpage, ABAQUS
