球栅数组封装英语:BGA、Ball Grid Array,以下简称BGA)技术为应用在集成电路上的一种表面黏着封装技术,此技术常用来永久固定如微处理器之类的的设备。BGA封装能提供比其他如双列直插封装(Dual in-line package)或四侧引脚扁平封装(Quad Flat Package)所容纳更多的接脚,整个设备的底部表面可全作为接脚使用,而不是只有周围可使用,比起周围限定的封装类型还能具有更短的平均导线长度,以具备更佳的高速性能。

焊接BGA封装的设备需要精准的控制,且通常是由自动化进程的工厂设备来完成的。BGA封装设备并不适用于插槽固定方式。

Ball grid array 球栅阵列封装

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter. The leads are also on average shorter than with a perimeter-only type, leading to better performance at high speeds.
