PCB制程工控电路板维修方法电路板维修分为有图维修和无图维修有图维修法就是参照原理图,分析电路原理和信号趋势,然后对关键点进行信号测试。 遇到这种情况,维修电路很容易,但是很多工控板都没有原理图,电路板厂家也不会保密给一般用户。专业维修公司,几乎所有电路板都是无图纸维修。 把我这几年无图纸修电路板的经验和大家交流一下,希望大家多多指教。电路板由电路板、元器件和软件组成。 在我看来,维修电路板时,维修人员的能力和检查工具是非常重要的。 没有必要的工具,仅凭经验维护现代电路板是很困难的,不注重人员素质也很难提

PCB工艺芯片封装技术详解1、BGA(ball grid array)也叫CPAC。 球形触点排列,表面贴装封装之一。 在显示模式下,在印刷基板的背面做一个球形凸块来代替引脚,在印刷基板的正面组装LSI芯片,然后用模压树脂或灌封方法密封。 也称为凸点显示载体 (PAC)。 引脚数可超过200个,是用于多引脚LSI的封装。 封装体也可以小于 QFP(四侧引脚扁平封装)。 例如360脚的BGA,脚中心距为1.5mm,只有31mm见方; 0.5mm中心距的304针QFP为40mm见方。 而且BGA不用像QFP那
