不错,多谢vince1981的分享。坛内几个搞LED可靠性朋友可能比较需要看看。
LED vince1981看得出对LED可靠性研究很深。多向你学习。。。 文章我也是转载而已。led看似简单,但也是半导体器件,想很有研究不是一朝一夕的事,我也是接触到皮毛而已,所以大家相互学习。 vince,不错呀!继续努力!盼望有自己的文章出来了。 一定好好努力不辜负科长的期望,呵呵 原帖由vince1981于2007-8-911:55发表http://www.kekaoxing.com/club/images/common/back.gif
一定好好努力不辜负科长的期望,呵呵
科长??:lol强啊!欢迎常来中国可靠性论坛做客!:victory: 强人! 谢谢分享,最近在研究sld的可靠性问题,希望能从led上找些需要的东东。

这些好DD我怎么都看不到列!呵呵
要是有时间发到我的油箱!
谢谢了~
