style="text-indent:25px">PCB與PCBA的區(qū)別。從上面的介紹就可知道，PCBA泛指的是一個(gè)加工流程，也可以理解為成品線路板，也就PCB板上的工序都完成了后才能算PCBA。而PCB則指的是一塊空的印刷線路板，上面沒有零件。電腦上打開PCB設(shè)計(jì)圖，把短路的網(wǎng)絡(luò)點(diǎn)亮，看看什么地方離得近，容易連到一塊。特別要注意IC內(nèi)部的短路。二、如果是人工焊接，要養(yǎng)成好的習(xí)慣：1、焊接前要目視檢查一遍PCB板，并用萬用表檢查關(guān)鍵電路（特別是電源與地）是否短路；2、每次焊接完一個(gè)芯片就用萬用表測一下電源和地是否短路；3、焊接時(shí)不要亂甩烙鐵，如果把焊錫甩到芯片的焊腳上（特別是表貼元件），就不容易查到。河北專業(yè)PCBA電路板生產(chǎn)</p><p
