研究了烧蚀层、软冲头、模具深度和激光能量对 Al/Cu 新型微铆接的影响。烧蚀层厚度显着影响金属流动，包括颈部和互锁；总结了合理的烧蚀层厚度与一定激光能量范围之间的关系。 100μm 的软冲头比其他厚度的冲头更适合该工艺。在可接合的激光能量范围内，随着激光能量的增加，互锁厚度逐渐增加，而颈部和底部厚度逐渐减小。获得了Al/Cu组合的工艺窗口，上下金属箔之间不可避免地存在一定的厚度差，至少为40μm。对于每种可接合的组合，当每种金属箔的厚度小于200μm时，基于铝箔和铜箔的厚度导出最佳模具深度的匹配函数。单搭接剪切试验表明，接头的拉伸强度和失效模型均取决于颈部和互锁厚度；只有同时形成大互锁和大颈部的接头才能获得高连接强度。
The influences of ablative layer, soft punch, die depth, and laser energy on novel micro clinching of Al/Cu were investigated. Ablative layer thickness notably influenced metal flow including neck and interlock; the relationship between reasonable ablative layer thickness and certain laser energy range was summarized. Soft punch with 100 μm was more suitable than with other thickness for the process. In the joinable laser energy range, with increase of laser energy, interlock thickness gradually increased, whereas the neck and bottom thicknesses gradually decreased. The process window of Al/Cu combination was acquired, and a certain thickness difference which was at least 40 μm inevitably existed between the upper and lower metal foils. For every joinable combination, matching function of optimum die depth are derived based on Al and Cu foil thickness when the thickness of each metal foil was less than 200 μm. The single lap shearing test showed that the tensile strength and failure model of the joint both depended on neck and interlock thicknesses; only the joint that simultaneously formed a large interlock and large neck can attain a high joining strength.
