有哪些好处？

Based on the review of the developed Pb-free solders and their applications, the failure behavior and the life prediction methodologies for Pb-free solder joints were presented and discussed.

针对目前所开发的无铅焊料，文中介绍电子封装结构中焊点的破坏行为和焊点寿命预测的基本方法。

Product name, part number, supplier's logo, QC stamp, Pb-free display and date must be printed on the package case.

包装箱上有产品名称、型号、厂家标识、厂家质量部门的检验合格证、制造日期等。

One of the main objectives of this study is to develop a generic thermo-mechanical durability model for Pb-free solders.

这项研究的主要目标之一是建立一个通用的热机械为无铅焊料的耐久性模型。
