PCB、PCBA、SMT有哪些区别与联系?2021-10-21 16:23·猎板PCB打样提起PCB大家都很熟悉,PCB又叫电路板、线路板,硬件工程师少不了要打几款板子。但提起SMT、PCBA,却很少有人了解是怎么回事,甚至经常有人将这几个概念混淆,今天就来讲讲,PCB、PCBA、SMT之间有哪些区别,又有哪些联系?PCB:中文名称为印制电路板,又称印刷线路板(Printed Circuit Board的缩写),是用来支撑电子元器件的载体,并提供线路,使电子元器件之间可以形成一个完整的电路。SMT:SMT是表面组装技术(Surface Mounted Technology的缩写),目前流行的一种工艺技术,通过一道道工序将电子元器件贴装在PCB板上,又称表面贴装技术。PCBA:指经过原材料采购,再进行SMT贴片,DIP插件,测试以及成品组装等一站式服务的加工制程(Printed Circuit Board Assembly的缩写)。解释一下就是“PCB是个板子,SMT是种技术,PCBA是个过程/成品”,在一个PCB空板上,进行SMT贴片(或者DIP插件),得到的成品可以称为PCBA,或者这个过程可以称为PCBA。当我们拆开电子产物时,可以看到电路板上焊满元器件,这时的电路板就是经过PCBA处理的PCB了。目前,猎板已经从PCB转向PCBA一站式服务,支持元器件代采,SMT贴片加工、测试、组装服务。从PCB生产到PCBA成品,一站式服务可以解决用户订单外发的担心,无需担心后续问题。从PCB制板,到元器件采购,SMT贴片加工,PCBA成品,我们更专业!
