style="text-indent:25px">六、測試探針選擇選擇測試探針，首先了解測試探針，懂得測試探針的基本知識，也就是所謂“懂行”。只有懂行者才知道如何選擇測試探針。七、測試探針原理探針是作為一個媒介，探針放在套管里，探針頭接觸待測物，另一端的套管引出線將信號傳導(dǎo)出去，接收回來的信號在測試機(jī)里處理，比如電阻利用電流源計(jì)算探針兩端的壓降，電容以定電壓源不同頻率去計(jì)算充電時間的斜率，探針在制成治具時他有可連續(xù)使用的特性，且成本不高。因此，它在測試界一直被普遍使用。八、測試探針更換時間無論什么探針都會有自己的壽命，探針的圖冊上一般都有自己的壽命期限標(biāo)注。但探針到底需要用多久更換新的，這個主要取決于彈簧的壽命和其它影響測試探針壽命的相關(guān)因素。</p><p

style="text-indent:25px">在PCB電路板和元器件生產(chǎn)制造過程中，提高貼片加工的生產(chǎn)效率和良品率尤為重要，為企業(yè)降低生產(chǎn)成品，可以提高企業(yè)的經(jīng)濟(jì)效益。如何提高生產(chǎn)效率和良品率，需要我們在投入大規(guī)模產(chǎn)量之前，進(jìn)行smt貼片加工可焊性測試，這時我們需要對測試pcb原型的樣品進(jìn)行老化處理。因?yàn)?，剛剛生產(chǎn)出來的元器件或PCB電路板，其焊接面的可焊性一般是不存在問題的，但是存放一段時間后，就會因?yàn)檠趸霈F(xiàn)劣化，測試必須考慮正常儲存條件對可焊性的影響。恒溫恒濕試驗(yàn)箱發(fā)現(xiàn)一項(xiàng)技術(shù)是否合適取決于焊端鍍層的金屬性能和預(yù)期引起產(chǎn)品質(zhì)量下降的原因。在pcb電子制造行業(yè)，元器件和PCB往往要求有一定的儲存保質(zhì)期，通常為6-12個月。因此，要等待這段周期后再進(jìn)行測量顯然不切實(shí)際，因而必須采用加速存放老化的方法，常用的試驗(yàn)設(shè)備為高壓加速老化試驗(yàn)箱。通過對加速老化進(jìn)行了專題研究，包括從1h蒸汽老化到一個月或數(shù)個月的濕熱條件測試技術(shù)。對錫合金而言氧化是主要原因，而對貴金屬鍍層而言則擴(kuò)散是主要原因。電子制造業(yè)界通常的做法是，對錫合金采用8~24h的蒸汽老化；對主要由擴(kuò)散而引起品質(zhì)下降的鍍層，采用115℃、16h干熱老化；對品質(zhì)下降機(jī)理不明的鍍層，則采用蒸汽老化。什么是測試治具？你了解多少呢？廣州開短路測試</p><p
