其实热风和红外BGA返修台各有各的特点,最好的是购买热风和暗红外相结合的BGA返修台,这样子的话可以很好的取长补短。很多人都喜欢底部是红外,上部是热风的BGA返修台最主要的原因是热风的加热速度快,焊接一般不会超过5分钟,还有就是热风一般焊接的质量会比较好。温度控制比较精准,对BGA和PCBA基板的颜色没有限制。


当然了热风BGA返修台的不足之处肯定是有的,就是温度的渗透性不是很强,鉴于散热比较快造成温度持续性差。而红外BGA返修台的优势加热渗透性好,也较为持久性,应该说可以非常好弥补热风BGA返修台的不足之处。红外BGA返修台也有其缺陷,那便是加热较慢,温度不太好调节,就等于是要不温度提不上,如果一旦温度上来了你想要降下去又比较慢。还有就是对于颜色也是比较敏感的,像白色的PCBA基板会反光,造成热量吸收不均匀。


归纳上述分析,比较好的BGA返修台就是上部采用热风加热,下部辅以大面积暗红外加热,这可以最大限底的保证温度的持续性,进而提升BGA芯片的返修良率。像190bp踢球者即时指数智能BGA返修台DEZ-R850就是这样的一款产品,如有需要可电话详询。
