What are the points of the quality inspection of pcba proofing? In order to achieve SMT's quality goals of high yield and high reliability, it is necessary to control the design scheme, components, data, process, equipment, rules and regulations of th

In the welding process of SMT chip processing, short circuit is a common processing situation. In order to achieve good results, the short circuit problem must be solved. If there is a short circuit on the PCBA circuit board, it must not be used. There ar

印刷電路板組裝 PCBA加工是電子設(shè)備制造中的關(guān)鍵階段。 PCBA 由裝置在印刷電路板 (PCB) 上的電子元件組成，然后將其焊接在一同以創(chuàng)立功用設(shè)備。 PCBA加工階段觸及幾個(gè)步驟，包括PCB設(shè)計(jì)、元件放置、焊接、測(cè)試和檢查。 PCBA加工的第一步是PCB設(shè)計(jì)。 這觸及運(yùn)用 Eagle、Altium 或……

在PCBA加工領(lǐng)域，大家經(jīng)常會(huì)聽到貼牌材料，那么什么是pcba代工代料呢？有什么優(yōu)勢(shì)？ 　　一、pcba代工代料的含義。 　　從狹義上講，pcba代工代料是指采購PCB板、電子元器件及PCBA加工的服務(wù)。 　　從廣義上講，pcba代工代料是指提供從電子方案設(shè)計(jì)、電子產(chǎn)品開發(fā)到材……

PCB打樣是指印刷電路板在批量生產(chǎn)前的試生產(chǎn)。主要用于電子工程師設(shè)計(jì)電路和完成PCB后，經(jīng)過小批量試生產(chǎn)到工廠，就是PCB打樣了。 　　PCB打樣的生產(chǎn)數(shù)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(duì)產(chǎn)品設(shè)計(jì)進(jìn)行確認(rèn)和測(cè)試。 　　PCB打樣的目的是檢查設(shè)計(jì)的電路是否在產(chǎn)品上進(jìn)行了嘗試，并檢驗(yàn)板廠的工藝和質(zhì)量。如果PCB設(shè)計(jì)師的打樣板符合要求，他們就可以開始批量生產(chǎn)了。 　　PCB打樣的好處： 　　1.它可以判斷PCB制造商的實(shí)力

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(cè)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(guī)范相關(guān)學(xué)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(huì)將PCB板過回流焊，完成貼片的焊接。 2、波峰焊接 回流焊是對(duì)貼片元器件的焊接，關(guān)于插件類型的元器件需求用到波峰焊停止焊接。普通將PCB

In the welding process of smt chip processing, the substance that can purify the welding metal and the welding surface and help welding is called flux, or flux for short. Flux is an indispensable process material in the soldering process. Liquid fluxes ar

In the PCBA processing process, due to the complex process, various processing equipment and materials will be used, so there will always be some levels of pollution. Among them, the source of pollutants is mainly from tin slag and flux residues during pr

In the process of smt patch processing, quota management should be implemented for solder paste, patch glue, and component loss as one of the control contents of key processes. The production of smt patch directly affects the quality of the product, so it

PCBA processing requires many protective measures, such as dust-proof, moisture-proof, anti-salt spray, anti-static, etc. Today, we mainly understand the dust-proof measures in the PCBA processing process. Anyone familiar with the PCBA industry knows that

The SMT chip processing workshop has environmental requirements for cleanliness, humidity and temperature, and it needs to work according to certain environmental requirements during processing. At the same time, we also need to pay attention to related m
