PCB，印刷電(dian)(dian)(dian)路(lu)板(ban)，電(dian)(dian)(dian)子元(yuan)器(qi)(qi)件中***常見應用。凡是我們能見到(dao)(dao)的電(dian)(dian)(dian)子設(she)備(bei)都(dou)(dou)都(dou)(dou)離不開PCB，小到(dao)(dao)電(dian)(dian)(dian)子手表、計算器(qi)(qi)、通(tong)用電(dian)(dian)(dian)腦，大到(dao)(dao)計算機、通(tong)迅電(dian)(dian)(dian)子設(she)備(bei)、***武器(qi)(qi)系統，只要有集(ji)成電(dian)(dian)(dian)路(lu)等電(dian)(dian)(dian)子無器(qi)(qi)件，它(ta)們之間電(dian)(dian)(dian)氣互連都(dou)(dou)要用到(dao)(dao)PCB。它(ta)提(ti)(ti)供集(ji)成電(dian)(dian)(dian)路(lu)等各種(zhong)電(dian)(dian)(dian)子元(yuan)器(qi)(qi)件固定裝配(pei)的機械支撐(cheng)、實現集(ji)成電(dian)(dian)(dian)路(lu)等各種(zhong)電(dian)(dian)(dian)子元(yuan)器(qi)(qi)件之間的布線和電(dian)(dian)(dian)氣連接或(huo)電(dian)(dian)(dian)絕緣、提(ti)(ti)供所要求(qiu)的電(dian)(dian)(dian)氣特性，如特性阻抗等。同時為自(zi)動錫焊提(ti)(ti)供阻焊圖形；為元(yuan)器(qi)(qi)件插(cha)裝、檢查、維修(xiu)提(ti)(ti)供識別字符和圖形。

循著PCB發展(zhan)歷程，我們(men)可以清晰地看到(dao)，經過改革開(kai)放后20多(duo)年(nian)尤其(qi)是新世(shi)紀(ji)以來最(zui)近幾年(nian)的(de)迅猛發展(zhan)，國內PCB產(chan)(chan)業由小到(dao)大，由弱到(dao)強(qiang)，已經使中國昂首成(cheng)為***大PCB產(chan)(chan)出國，并以強(qiang)勁的(de)發展(zhan)勢頭，全(quan)力(li)沖(chong)擊世(shi)界PCB產(chan)(chan)業***領域(yu)。
