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。在PCBA貼片加工過程中，靜電一直是造成芯片損壞的一大重要因素。</p><div

style="text-indent:25px">感應(yīng)線圈。也就是我們常說的電感，它可以儲存磁能。PCBA加工中的電感線圈通常由框架、繞組、屏蔽罩、鐵芯等組成。電位器的電阻可以改變。在PCBA加工過程中，電阻需要在規(guī)定的范圍內(nèi)連續(xù)調(diào)節(jié)，稱為電位器。電位器由外殼、滑動端、轉(zhuǎn)軸、環(huán)形電阻體和三個引線端組成。4、變壓器變壓器一般由鐵芯（或鐵芯）和線圈組成。線圈有兩個或兩個以上的繞組，其中與電源相連的繞組稱為一次線圈，其余的稱為二次線圈。變壓器是轉(zhuǎn)換電壓、電流和阻抗的裝置。當一次線圈中有交流電流時，磁芯中會產(chǎn)生交流磁通，使二次線圈中的電壓感應(yīng)。變壓器主要用于交流電壓變換、電流變換、功率變換、阻抗變換和緩沖隔離。它是PCBA工藝的重要組成部分之一。Pcba電路板變壓器。變壓器由鐵芯和線圈組成，線圈有兩個或兩個以上的繞組。PCBA電路板公司</p><p
