style="text-indent:25px">PCBA加工的工藝流程主要包括三大工藝，即PCB線路板制造、SMT貼片加工、DIP插件加工，其中，SMT貼片加工和DIP插件加工都需要用到各種類型電子元器件，電子元器件是PCBA加工過程中必須用到的基礎(chǔ)部件，它們的品質(zhì)直接影響到PCBA成品功能和電子產(chǎn)品成品質(zhì)量。PCBA加工是經(jīng)過SMT貼片和DIP插件等工藝將所需電子元器件焊接安裝到PCB板上的整個過程。其中所用到的電子元器件通常有以下幾種：電阻，電容，電感線圈，變壓器，二極管，三極管，場效應(yīng)管等，現(xiàn)在金而特電子為您逐一介紹一下各個電子元器件的功能特性。北京單面PCBA電路板生產(chǎn)廠家</p><p
