电子产品结构防护设计

  1. 避免积水结构。产品的外型恰当地倾斜,尽量减少孔、槽等,在可能积水和留存湿气的空间开设排水和排气孔,并避免凹凸不平的表面等。
  2. 湿度较大的气候环境下,尽量避免采用点焊、铆接、螺纹紧固等结构形式,优先选用板金结构或整体浇铸机箱的结构形式,以避免形成缝隙腐蚀,同时在能形成缝隙腐蚀处加以密封处理或加密封衬垫。
  3. 同一种结构中,如使用了不同类型的金属,则应在其中一种金属上镀涂上允许与第二种金属相接触的金属镀层,或两种金属材料均镀上同一种金属镀层,或在两种金属之间涂绝缘保护层或放置衬垫,此时应兼顾设备的电磁兼容性要求。
  4. 在有可能产生应力腐蚀裂开的情况下,应注意避免引起应力集中的结构形式,并采取适当的工艺措施消除内应力。
  5. 最容易发生腐蚀和最大腐蚀部位加厚构件尺寸,通常称为“腐蚀裕度”,一般取预期寿命所需量的两倍。对于易受腐蚀损坏而必须经常维护和更换的零件,应从结构上保证易于维修、更换。
