手机为例,感悟一下点胶对于提升产品品质的影响有多大?

手机几乎成了我们的生活必备,大到80岁老人,小到1岁宝宝都沉浸在手机的世界不可自拔。除了配置、价格等因素,手机的质量是人们最关注的话题。手机每天拿在手上,“抗摔”,这的确是手机消费者极看重的品质。

早年诺基亚功能机坚不可摧的印象深入人心,虽笑传能砸核桃能捶钉子,可调侃背后更多的是对那份可靠的赞叹。近年的智能手机也表现出了不俗的耐摔性,耐跌落的秘诀才被引入于大众的视线里------点胶。厂商对手机关键部件点胶与否,点胶实施到什么程度有多好,都极大程度上决定着手机的稳健与可靠。


把很多知名厂家的手机进行拆解分析,你会发现绝大多数都做了点胶保护。一般手机厂商都会对AP芯片和字库芯片用高强度胶水进行点胶固化,以确保手机跌落时芯片不易损坏。 “随着芯片针脚密度越来愈高,芯片面积越来愈大点胶逐渐成了保护电路板的重要工艺,在其他工艺水平同等条件下,点胶会显著提升产品可靠性与寿命”。

那么点胶为什么会起到保护作用的?

点胶通过对芯片焊球或元器件焊点的保护来避免跌落、挤压、弯折后焊接开裂而引发的功能失效;点胶也具有防水、防光透、密封等不同作用。

① 防止电路板芯片与基材的热应力系数不一致,热应力拉扯导致的焊球脱落及焊点断裂。


② 能防止由于跌落或震动引起的芯片或焊点损坏;


③ 能防止焊球应力分布不均匀后焊球开裂引发的功能失效。

④ 整体包封。能防水,防震。

⑤ 填缝密封,防水(如摄像头)。


⑥ 粘接,密封防水,胶水的使用,取代了多数的螺丝、胶带,使产品变得更美观。


随着科技的发展,人们对电子产品的多样化以及创新程度要求越来越高,同样的,目前电子产品发展趋势已经对点胶有越来越高水准的期待和要求。

通过使用点胶机对产品实行点胶,我们的产品得到更好的保护,品质得到大大的提升。
