style="text-indent:25px">PCBA包工包料從單純包工包料到提供升級換代方案。產(chǎn)品的競爭日益激烈，升級換代也越來越快。越來越多的大客戶，也要求代工廠能夠在完成包工包料生產(chǎn)過程中工作的同時，逐步提供一些開發(fā)的工作。由于代工廠長期生產(chǎn)測試產(chǎn)品，對于整個設備的電氣性能掌握的比較全；如果不是特別大的改動，**是體積，功耗，穩(wěn)定性、用戶體驗和成本方面的考量的話，完全可以通過代工廠來實現(xiàn)產(chǎn)品的升級改造。這樣，代工廠也就必須在PCB制作、電源設計、穩(wěn)定性設計方面有所準備和積累，才能夠從容應對客戶發(fā)來的需求。PCBA打樣是PCBA批量生產(chǎn)前必須要進行的一個重要環(huán)節(jié)。邳州電子產(chǎn)品pcba制造商</p><p style="text-indent:25px">在制造工藝，特別是在測試中，不斷增加的PCBA復雜性和密度不是一個新的問題。邳州電子產(chǎn)品pcba制造商</p><p style="text-indent:25px">PCBA盡量使用回流焊接，減少手工焊接。一般在使用電烙鐵進行手工焊接時，對焊接人員的技術(shù)要求比較高，烙鐵頭的溫度過高過低或者在焊接時，焊接的元器件發(fā)生松動，都容易引起虛焊和假焊，使用回流焊接可以減少人為的外在因素，提高焊接的品質(zhì)。有人問，如果遇到電烙鐵的溫度過高或低這個問題，我們在操作之前應該怎么避免呢？我們可以在PCBA焊接的后焊加工和維修時，都需要使用電烙鐵進行手工焊接。在使用電烙鐵時，不規(guī)范的操作，導致烙鐵頭的溫度過高或者過低，都極易造成虛焊和假焊。因此，在焊接時，要保持烙鐵頭干凈，根據(jù)不同的部件和焊點的大小、器件形狀來選擇不同功率類型的電烙鐵，把焊接的溫度控制在300℃—360℃之間。在PCBA焊接加工過程中引起的虛焊和假焊，是由很多因素造成的，以上只是列舉了一些比較常見的原因，通過以上這些預防措施，再結(jié)合實際的情況，就可以有效的減少虛焊和假焊焊接缺陷了。邳州電子產(chǎn)品pcba制造商</p><p
