線路板生產廠家：線路板的安裝工藝

線(xian)路(lu)板幾乎我們(men)能見到(dao)(dao)的(de)電(dian)(dian)(dian)子設備都離(li)不(bu)開它，小到(dao)(dao)電(dian)(dian)(dian)子手(shou)表、計(ji)算器(qi)、通(tong)用(yong)電(dian)(dian)(dian)腦，大到(dao)(dao)計(ji)算機(ji)、通(tong)迅電(dian)(dian)(dian)子設備、***武器(qi)系統，只要有集(ji)成電(dian)(dian)(dian)路(lu)等(deng)電(dian)(dian)(dian)子無器(qi)件，線(xian)路(lu)板之間電(dian)(dian)(dian)氣(qi)(qi)互連都要用(yong)到(dao)(dao)PCB,線(xian)路(lu)板。線(xian)路(lu)板提(ti)供(gong)集(ji)成電(dian)(dian)(dian)路(lu)等(deng)各種電(dian)(dian)(dian)子元(yuan)器(qi)件固(gu)定裝(zhuang)配的(de)機(ji)械支撐、實現集(ji)成電(dian)(dian)(dian)路(lu)等(deng)各種電(dian)(dian)(dian)子元(yuan)器(qi)件之間的(de)布線(xian)和電(dian)(dian)(dian)氣(qi)(qi)連接或電(dian)(dian)(dian)絕緣、提(ti)供(gong)所要求(qiu)的(de)電(dian)(dian)(dian)氣(qi)(qi)特(te)性，如特(te)性阻(zu)抗等(deng)。同時(shi)為自動錫焊(han)提(ti)供(gong)阻(zu)焊(han)圖形;為元(yuan)器(qi)件插裝(zhuang)、檢查、維修提(ti)供(gong)識別(bie)字符(fu)和圖形。

我(wo)們(men)常見的(de)電(dian)腦板(ban)卡基本上(shang)(shang)是(shi)環氧樹脂玻璃布(bu)基雙(shuang)面(mian)(mian)印(yin)制(zhi)PCB,線路(lu)(lu)板(ban)，其(qi)中(zhong)有一(yi)(yi)面(mian)(mian)是(shi)插裝元(yuan)(yuan)件(jian)(jian)另一(yi)(yi)面(mian)(mian)為元(yuan)(yuan)件(jian)(jian)腳(jiao)焊(han)(han)(han)接面(mian)(mian)，能看(kan)出焊(han)(han)(han)點(dian)很有規則，這些焊(han)(han)(han)點(dian)的(de)元(yuan)(yuan)件(jian)(jian)腳(jiao)分(fen)立(li)焊(han)(han)(han)接面(mian)(mian)我(wo)們(men)就叫它為焊(han)(han)(han)盤(pan)。為什么其(qi)它銅導線圖形不上(shang)(shang)錫(xi)(xi)呢。因(yin)為除了需要錫(xi)(xi)焊(han)(han)(han)的(de)焊(han)(han)(han)盤(pan)等部分(fen)外，其(qi)余(yu)部分(fen)的(de)表面(mian)(mian)有一(yi)(yi)層(ceng)耐波峰焊(han)(han)(han)的(de)阻(zu)焊(han)(han)(han)膜(mo)。其(qi)表面(mian)(mian)阻(zu)焊(han)(han)(han)膜(mo)多(duo)數(shu)為綠色，有少數(shu)采用***、黑色、藍(lan)色等。所以在PCB,線路(lu)(lu)板(ban)行?我(wo)們(men)從電(dian)腦板(ban)卡可以看(kan)出，元(yuan)(yuan)件(jian)(jian)的(de)安裝有三種方式。一(yi)(yi)種為傳(chuan)動的(de)插入式安裝工(gong)藝，將電(dian)子元(yuan)(yuan)件(jian)(jian)插入印(yin)制(zhi)PCB,線路(lu)(lu)板(ban)的(de)導通孔里。這樣就容(rong)易(yi)看(kan)出雙(shuang)面(mian)(mian)印(yin)制(zhi)PCB,

線路板的導通孔有(you)如下幾種：

一是單純的元件插裝孔(kong);

二是元件插裝與雙面(mian)互連(lian)導(dao)通(tong)孔;

三是單(dan)純的雙面導通孔;四是基板(ban)安裝與(yu)定(ding)位(wei)孔。

另二種安(an)(an)裝方式(shi)就(jiu)是(shi)(shi)表(biao)面安(an)(an)裝與芯片(pian)直接安(an)(an)裝。其(qi)實芯片(pian)直接安(an)(an)裝技術可以認為是(shi)(shi)表(biao)面安(an)(an)裝技術的分支(zhi)，它是(shi)(shi)將芯片(pian)直接粘在印制板上，再用線焊法(fa)或載帶(dai)法(fa)、倒裝法(fa)、梁式(shi)引線法(fa)等封裝技術互聯(lian)到印制板上。
