中文摘要
这项提议是与一家设计和制造无线手持设备的工业合作伙伴合作的延续。这是一个竞争激烈的行业,由于激进的小型化,其塑料外壳和电子元件的墙壁正迅速变得越来越薄。众所周知,聚合物材料对湿度和温度很敏感,但在使用中遇到的条件下,它们如何老化还存在很大的不确定性。聚合物材料的机械和物理性能也会随着老化而发生深刻的变化,但这些变化的程度以及它们可能如何对关键部件的可靠性产生不利影响目前还不容易预测。
英文摘要
This proposal is a continuation of a collaboration with an industrial partner who designs and manufactures wireless handheld devices. This is a highly competitive industry which is rapidly moving towards increasingly thinner walls for its plastic housings and electronic components due to aggressive miniaturization. It is well known that polymeric materials are sensitive to moisture and temperature but there is much uncertainty about how they would age under conditions encountered in service. The mechanical and physical properties of polymeric materials also change profoundly with aging but the extent of these changes and how they may adversely affect the reliability of critical components cannot be readily predicted as yet.
