PCBA打樣加工廠的覆銅注意事項

2023-05-08

PCBA打樣廠有一些板材需要覆銅處理。根據覆銅板的機械剛度，有剛性覆銅板和柔性覆銅板之分。鍍銅可以有效降低SMT芯片加工產品的接地阻抗，提高抗干擾能力，降低壓降，提高功率效率，減少回路面積。鍍銅是貼片印刷電路板非常有用的加工方法，在鍍銅加工中需要注意的點很多。所謂鍍銅，就是把PCB上的閑置空間作為基準面，然后用實心銅填充。這些銅區域也被稱為銅填充。鍍銅的意義在于降低地線阻抗，提高抗干擾能力；降低壓降，提高功率效率；此外，連接地線以減少回路面積。銅包線有幾個問題需要處理:一是異地單點連接，用0歐姆電阻或磁珠

What are the advantages of PCBA OEM?

2023-04-20

PCBA is to complete the whole process of PCB empty board through smt and dip plug-ins. In the entire processing process, the process is complex, the production is fine, and the required components are various. The insertion, welding and testing of various

PCBA打樣小批量的質量檢測有哪些

2023-04-20

PCBA打樣小批量的質量檢測有哪些，為了完成PCBA加工一次合格率和高牢靠性的質量目的，需求對印刷電路板設計計劃、元器件、材料、工藝、設備、規章制度等停止控制。其中，基于過程控制在PCBA打樣制造業中尤為重要。在PCBA打樣制造過程的每一步，都要按照合理的檢測辦法，防止各種缺陷和隱患，才干進入下一道工序。 PCBA打樣加工和焊接檢測是對焊接產品的全面檢測。普通需求檢測的點有：檢測點焊外表能否光亮，有無孔洞、孔洞等；點焊能否呈月牙形，有無多錫少錫，有無立碑、橋梁、零件挪動、缺件、錫珠等缺陷。各

SMT貼片加工工藝的優勢是什么

2023-04-07

我經常聽到人們談論SMT指針。對于業內廣大人士來說，這種設備并不陌生。其實SMT指針也叫部分計數器。那么，你對這個設備的功能了解多少？　　據相關業內人士介紹，SMT芯片加工中使用的SMT指針是基于光電傳感原理，通過零件載體利用導孔與零件的對應關系，可以精確測量SMD零件的數量，從而達到方便快捷計數的目的……

PCBA打樣加工對車間的環境詳細請求

2023-04-07

車間是PCBA工廠的大動脈，大局部的消費與加工都要在車間內部停止。關于一家PCBA工廠而言，車間的環境及人員素質是彰顯其公司文化修養與優秀水平的關鍵。那么今天，我們就走進車間，理解一下PCBA打樣加工對車間環境及人員的請求吧。 PCBA打樣加工的PCBA消費設備和SMT貼片加工工藝對車間的電源、通風才能、溫度、濕……

What are the PCBA processing modes?

2023-03-31

There are two main modes of PCBA processing cooperation, one is PCBA processing mode, and the other is PCBA OEM processing mode. The PCBA processing mode generally refers to pure processing, while the PCBAOEM processing mode generally refers to all links

Why should PCBA be preheated before processing?

2023-03-31

Temperature profiles are very important in mass production PCBA processing and soldering environments. During smt placement, a slow ramp-up and preheat phase helps activate flux, avoid thermal shock and improve solder quality. However, when it comes to re
