集成电路封装作用
集成电路封装不仅起到集成电路芯片内键合点与外部进行电气连接的作用,也为集成电路芯片提供了一个稳定可靠的工作环境,对集成电路芯片起到机械或环境保护的作用,从而集成电路芯片能够发挥正常的功能,并保证其具有高稳定性和可靠性。总之,集成电路封装质量的好坏,对集成电路总体的性能优劣关系很大。因此,封装应具有较强的机械性能、良好的电气性能、散热性能和化学稳定性。
虽然IC的物理结构、应用领域、I/O数量差异很大,但是IC封装的作用和功能却差别不大,封装的目的也相当的一致。作为“芯片的保护者”,封装起到了好几个作用,归纳起来主要有两个根本的功能:
(1)保护芯片,使其免受物理损伤;
(2)重新分布I/O,获得更易于在装配中处理的引脚节距。封装还有其他一些次要的作用,比如提供一种更易于标准化的结构,为芯片提供散热通路,使芯片避免产生α粒子造成的软错误,以及提供一种更方便于测试和老化试验的结构。
