What are the benefits of PCB proofing?

2023-11-03

PCB打樣是指印刷電路板在批量生產前的試生產。主要用于電子工程師設計電路和完成PCB后，經過小批量試生產到工廠，就是PCB打樣了。　　PCB打樣的生產數量一般選擇5件或10件。一般情況下，工程師稱其為PCB打樣，然后再對產品設計進行確認和測試。　　PCB打樣的目的是檢查設計的電路是否在產品上進行了嘗試，并檢驗板廠的工藝和質量。如果PCB設計師的打樣板符合要求，他們就可以開始批量生產了。　　PCB打樣的好處：　　1.它可以判斷PCB制造商的實力

PCBA加工有哪些焊接類型

2023-10-18

PCBA是什么意義？它是指從物料采購、PCB制造、SMT貼片加工、DIP插件加工、PCBA測試、廢品組裝等一系列的工藝流程。那么PCBA有哪些焊接類型呢？下面小編給大家引見些PCBA有哪些焊接類型，PCBA加工外觀規范相關學問。一、PCBA有哪些焊接類型 1、回流焊接首先PCBA的第一道焊接工序是回流焊接，在完成SMT貼裝之后，會將PCB板過回流焊，完成貼片的焊接。 2、波峰焊接回流焊是對貼片元器件的焊接，關于插件類型的元器件需求用到波峰焊停止焊接。普通將PCB
