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(dāng)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。</p><p style="text-indent:25px">pcba圖形電鍍。目的：圖形電鍍是在線路圖形裸露的銅皮上或孔壁上電鍍一層達到要求厚度的銅層與要求厚度的金鎳或錫層。流程：上板→除油→水洗二次→微蝕→水洗→酸洗→鍍銅→水洗→浸酸→鍍錫→水洗→下板。退膜。目的：用NaOH溶液退去抗電鍍覆蓋膜層使非線路銅層裸露出來。流程：水膜：插架→浸堿→沖洗→擦洗→過機；干膜：放板→過機。蝕刻。目的：蝕刻是利用化學(xué)反應(yīng)法將非線路部位的銅層腐蝕去。綠油。目的：綠油是將綠油菲林的圖形轉(zhuǎn)移到板上，起到保護線路和阻止焊接零件時線路上錫的作用。PCBA貼片流程比較復(fù)雜，任何一個環(huán)節(jié)出了問題都將引起焊接品質(zhì)問題。</p><div

style="text-indent:25px">PCBA加工中電子元器件的選用也是重中之重，PCBA也就是印制線路板經(jīng)過SMT貼片加工和DIP插件等加工環(huán)節(jié)的制程。在電子加工的過程中需要用到的電子元器件種類還是很多，下面專業(yè)PCBA代工代料加工廠佩特科技給大家簡單介紹一些常見的電子元器件。1、電阻電阻是具有電阻特性的電子元件，普遍應(yīng)用于PCBA加工中。電阻器分為固定電阻器和可變電阻器（電位器），它們在電路中起著均壓、分流和限流的作用。2、電容電容也是PCBA加工的基本元件之一。它是電能的儲存部件。它在電子電路中起著耦合、濾波、直流和調(diào)諧的作用。pcba電聲器件。在電路中用于完成電信號與聲響信號互相轉(zhuǎn)換的器件稱為電聲器件。四川軟硬PCBA電路板工廠</p><p style="text-indent:25px">pcba外表裝置元器件。它包括電阻器、電容器、電感器及半導(dǎo)體器件等。四川軟硬PCBA電路板工廠</p><p style="text-indent:25px">PCBA電路板清洗在PCB抄板、PCB生產(chǎn)加工等各個環(huán)節(jié)都有涉及,關(guān)于電路板清洗質(zhì)量或者效果的評估標(biāo)準(zhǔn),專業(yè)的工程師及加工工廠都需要遵循一定的原則,在此,我們提供PCB電路板清洗效果的正確評估標(biāo)準(zhǔn)和終檢查方法供大家參考。一、原材料質(zhì)量要求1、錫鉛焊料壓力加工錫鉛焊料的化學(xué)成分需符合GB/T 31311的要求。鑄造錫鉛焊料的化學(xué)成分需符合GB/T 8012的要求。2、焊劑關(guān)于焊劑質(zhì)量,應(yīng)該從焊劑的外觀、物理穩(wěn)定性和顏色、不揮發(fā)物含量、粘性和密度、水萃取電阻值、鹵素含量、固體含量、助焊性、干燥度、銅鏡腐蝕性、絕緣電阻、離子污染等方面進行檢測。四川軟硬PCBA電路板工廠</p><p
