今天，我想談?wù)?/span>pcb快速打樣印刷電路板制造中的一個(gè)關(guān)鍵部分——表面光潔度。表面處理在要安裝的部件和互連電路之間形成一個(gè)關(guān)鍵的接口。

作為一個(gè)提醒，本博客的重點(diǎn)之一是研究pcb快速打樣制造業(yè)所涉及的技術(shù)。As its most essential function, the final finish process is intended to provide exposed copper circuitry with a protective coating in order to preserve solderability. In a more expanded view, the final finish coating is required to meet dozens of functional criteria, including solderability, environmental, electrical, physical, and durability demands. The past decades have brought about a wholesale transformation in this segment of the industry - a wide variety of functional, environmental, engineering, cost, productivity, and failure mode issues have contributed to this frequent change.
作為其最基本的功能，最終的精加工工藝旨在提供暴露的銅電路，具有保護(hù)性涂層，以保持可焊性。

在一個(gè)更擴(kuò)展的視圖中，pcb快速打樣最終的涂層需要滿足幾十個(gè)功能標(biāo)準(zhǔn)，包括可焊性、環(huán)境、電氣、物理和耐久性要求。過去幾十年來，在這一行業(yè)中發(fā)生了一次大規(guī)模的變革——各種各樣的功能、環(huán)境、工程、成本、生產(chǎn)率和失效模式問題都促成了這種頻繁的變化。

Nonetheless, years of manufacturing experience and constant innovation has enabled PCB International to be a leading edge provider for all your surface finish needs. Including, but not limited to: HASL, ENIG (Immersion Gold), Organic solderability preservative (OSP), immersion silver, immersion tin, Electrolytic nickel/electrolytic gold, electroless gold, etc. Below lists the pros and cons of a number of the more popular surface finishes - most relevant in today’s applications. Please note that all of these are available at PCB International!
然而，多年的制造經(jīng)驗(yàn)和不斷創(chuàng)新，使pcb快速打樣成為領(lǐng)先的供應(yīng)商，為您所有的表面光潔度的需要。包括但不限于：HASL、EnIG（浸金）、有機(jī)可焊性防腐劑（OSP）、浸銀、浸入錫、電解鎳/電解金、化學(xué)鍍金等。下面列出了一些比較流行的表面處理的優(yōu)點(diǎn)和缺點(diǎn)-在ToDA中最相關(guān)的。Y的應(yīng)用。請(qǐng)注意，所有這些都可以在PCB國(guó)際！
