This research is directed at the warping of printed wiring boards, an increasingly detrimental factor in the assembly of fine pitch components and connectors. The research will determine the controlling factors that create the warpage condition, evaluate the influence of each factor, and determine which parameters can be controlled or eliminated in order to reduce the degree of stress related circuit card warpage. Both experimental and numerical techniques will be used for this evaluation.

本研究针对印刷线路的翘曲问题 董事会，一个越来越不利的因素，在组装的罚款 间距组件和连接器。 该研究将确定 产生翘曲条件的控制因素，评估 每个因素的影响，并确定哪些参数可以 控制或消除以减少压力程度 相关电路卡翘曲。 实验和数值 技术将用于这项评估。
