PCBA打樣廠有一些板材需要覆銅處理。根據(jù)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(chǎn)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(qū)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

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(zhì)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(zhì)量目的，需求對印刷電路板設(shè)計計劃、元器件、材料、工藝、設(shè)備、規(guī)章制度等停止控制。其中，基于過程控制在PCBA打樣制造業(yè)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(chǎn)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

PCBA processing is an electronic processing industry with a relatively high degree of mechanical equipment integration. The more and more mature smt processing industry and the improvement of manufacturing process continue to improve the yield and efficie

With the development of electronic processing technology and electronic technology, the overall demand for PCB is increasing. Many PCBA manufacturers used to only provide processing methods with supplied materials, but now provide one-stop service for OEM

我經(jīng)常聽到人們談論SMT指針。對于業(yè)內(nèi)廣大人士來說，這種設(shè)備并不陌生。其實SMT指針也叫部分計數(shù)器。那么，你對這個設(shè)備的功能了解多少？ 　　據(jù)相關(guān)業(yè)內(nèi)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(guān)系，可以精確測量SMD零件的數(shù)量，從而達到方便快捷計數(shù)的目的……

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(nèi)部停止。關(guān)于一家PCBA工廠而言，車間的環(huán)境及人員素質(zhì)是彰顯其公司文化修養(yǎng)與優(yōu)秀水平的關(guān)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(huán)境及人員的請求吧。 PCBA打樣加工的PCBA消費設(shè)備和SMT貼片加工工藝對車間的電源、通風才能、溫度、濕……

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

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

We all know that in SMT chip processing, SMT chip components and SMT ink cartridge components are the most commonly used components, and they each have their own unique characteristics. After different processing, the advantages are also different, so wha

First of all, see if the PCBA plate maker can really meet the proofing needs: 1、 Look at whether the manufacturer’s products are high-end, mid-range or low-end, and in which field the product is produced, whether the manufacturer can provide its own PC

Many customers do not know how to choose when looking for a PCBA processing factory. There are too many PCBA processing plants, and on the surface it seems that there is not much difference. So how can we find a suitable PCBA processing factory? It
