PCBA生產(chǎn)工藝流程 簡(jiǎn)介

pcba生產(chǎn)工藝流程 簡(jiǎn)介,pcba生產(chǎn)工藝流程英文

PCBA生產(chǎn)是指將電路板(PCB)上的元器件進(jìn)行貼裝加工制作出成品電路板。PCBA生產(chǎn)的工藝流程包括PCB制作、元器件采購及管理、SMT、DIP、測試等環(huán)節?,F代技術(shù)的不斷更新?lián)Q代,PCBA生產(chǎn)也越來(lái)越普及,成為電子制造業(yè)中至關(guān)重要的一部分。

1. PCBA的制作

PCBA的制作主要是通過(guò)PCB制作完成的,PCB是PCBA的骨架,是電子元器件的基礎支撐平臺。PCB的質(zhì)量對PCBA的質(zhì)量起到?jīng)Q定性的作用。PCB制作工序需要進(jìn)行印制、蝕刻、鉆孔、分板、抄板等步驟。

2. 元器件采購及管理

電子元器件采購及管理是PCBA生產(chǎn)中的重要環(huán)節。元器件采購質(zhì)量的好壞直接影響到PCBA的可靠性。因此,采購過(guò)程中要進(jìn)行嚴格的品質(zhì)及產(chǎn)地認證,以保證元器件的正常供貨及質(zhì)量。

3. SMT

SMT是PCBA生產(chǎn)中的重要環(huán)節,全名是Surface Mount Technology,中文是表面貼裝技術(shù),也就是將元器件直接通過(guò)貼裝在PCB上,較之于傳統的插件式電子產(chǎn)品SMT要簡(jiǎn)單得多。SMT生產(chǎn)工藝主要包括元器件的貼裝、貼裝預熱、回流焊等步驟。這一步驟需要考慮到元器件的尺寸、型號、間距、密度等因素。

4. DIP

DIP是PCBA生產(chǎn)中的另一個(gè)重要環(huán)節,全名是Dual in-line Package,中文稱(chēng)作雙列直插封裝,這種生產(chǎn)工藝主要是用于那些無(wú)法通過(guò)SMT工藝進(jìn)行貼裝的元器件,因此需要通過(guò)人工工藝進(jìn)行安裝。DIP安裝的工藝主要是描述DIP元器件的切割、下料、對排、部位確認、安裝測試等步驟。

5. 測試

測試是PCBA生產(chǎn)的最后一個(gè)環(huán)節,是指對PCBA成品進(jìn)行功能測試和可靠性測試。在測試過(guò)程中,需要用到一些專(zhuān)業(yè)的檢測設備和檢測工具,方能保障PCBA的各項性能指標得到滿(mǎn)足。

1. PCB fabrication.

PCB fabrication is the process of making the board or the skeleton for the PCBA. PCB is the support platform for electronic components. The quality of the PCB directly affects the quality of the final PCBA product. The PCB fabrication process involves printing, etching, drilling, dividing plates, and board copying.

2. Procurement and management of electronic components.

Procurement and management of electronic components is an important part of PCBA production. The quality of the components directly affects the reliability of the PCBA. Therefore, during the procurement process, strict quality and origin certification must be carried out to ensure the normal supply and quality of components.

3. Surface Mount Technology (SMT).

SMT is an important part of PCBA production. It involves directly placing electronic components on the PCB, hence making the product simpler as compared to traditional plug-in electronic systems. The SMT production process mainly includes component placement, preheating, and reflow soldering. In this process, the size, type, spacing and density of components must be considered.

4. Dual in-line Package (DIP).

DIP is another important part of PCBA production that is used for components that cannot be mounted using SMT technology. As such, the process involves manual installation. The DIP installation process mainly involves component cutting, feeding, positioning, installation, testing, and confirmation of positions.

5. Testing.
