在SMT貼(tie)片(pian)(pian)中(zhong)，貼(tie)片(pian)(pian)電(dian)(dian)(dian)感主要承(cheng)擔著扼流、退耦、濾波和調(diao)諧等作用(yong)(yong)(yong)。貼(tie)片(pian)(pian)電(dian)(dian)(dian)感的(de)種(zhong)類主要有(you)繞線型(xing)和疊層型(xing)兩種(zhong)。那么在SMT貼(tie)片(pian)(pian)時(shi)，又該怎么選(xuan)用(yong)(yong)(yong)合適(shi)(shi)(shi)的(de)貼(tie)片(pian)(pian)電(dian)(dian)(dian)感呢？下面巨源(yuan)盛的(de)技術員就給大家(jia)介紹一下貼(tie)片(pian)(pian)電(dian)(dian)(dian)感的(de)選(xuan)用(yong)(yong)(yong)原則。目(mu)前常見的(de)貼(tie)片(pian)(pian)電(dian)(dian)(dian)感有(you)三種(zhong)：一種(zhong)，微波用(yong)(yong)(yong)高(gao)頻電(dian)(dian)(dian)感。適(shi)(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)1GHz以上(shang)頻段使用(yong)(yong)(yong)。二種(zhong)，高(gao)頻貼(tie)片(pian)(pian)電(dian)(dian)(dian)感。適(shi)(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)諧振回路和選(xuan)頻電(dian)(dian)(dian)路中(zhong)。三種(zhong)，通用(yong)(yong)(yong)性電(dian)(dian)(dian)感。一般適(shi)(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)幾(ji)十兆(zhao)赫(he)茲的(de)電(dian)(dian)(dian)路中(zhong)。

電(dian)子元(yuan)件表面(mian)(mian)貼(tie)裝(zhuang)(zhuang)的(de)回(hui)流焊(han)(han)接工藝：它的(de)作用是將焊(han)(han)錫膏(gao)熔化(hua)，使電(dian)子元(yuan)件表面(mian)(mian)貼(tie)裝(zhuang)(zhuang)與PCB板牢固(gu)焊(han)(han)接在(zai)一起以(yi)達到設(she)(she)計所要(yao)求的(de)電(dian)氣性能并完(wan)全(quan)按(an)照曲(qu)線(xian)精(jing)密(mi)控制(zhi)。所用設(she)(she)備為(wei)回(hui)流焊(han)(han)機（全(quan)自動紅外/熱(re)風(feng)回(hui)流焊(han)(han)機），位于電(dian)子元(yuan)件表面(mian)(mian)貼(tie)裝(zhuang)(zhuang)生產線(xian)中(zhong)貼(tie)片機的(de)后面(mian)(mian)。

來(lai)看下雙面(mian)混裝工藝(yi)(yi)，SMT貼片(pian)焊(han)(han)接(jie)廠家，這種工藝(yi)(yi)師要(yao)兩面(mian)都需要(yao)貼片(pian)的(de)，一步(bu)就(jiu)是(shi)來(lai)料(liao)的(de)檢查，這是(shi)所(suo)以加(jia)工工藝(yi)(yi)的(de)步(bu)驟，SMT貼片(pian)焊(han)(han)接(jie)報價，然后(hou)PCB的(de)B面(mian)進行(xing)點貼片(pian)，B面(mian)需要(yao)固化，然后(hou)就(jiu)是(shi)翻板，撫順(shun)SMT貼片(pian)焊(han)(han)接(jie)，B面(mian)的(de)工藝(yi)(yi)已經(jing)完成，接(jie)下來(lai)就(jiu)是(shi)PCB的(de)A面(mian)插件，A面(mian)波(bo)峰焊(han)(han)，SMT貼片(pian)焊(han)(han)接(jie)加(jia)工哪家好(hao)，清洗，后(hou)一道工序(xu)就(jiu)是(shi)檢測(ce)，如果(guo)合格直接(jie)包裝，如果(guo)不合格進行(xing)返修，在整個(ge)過程當中(zhong)一定要(yao)注(zhu)意事行(xing)貼，然后(hou)再進行(xing)擦，這種工藝(yi)(yi)一般都是(shi)適(shi)用于一些分(fen)離(li)性的(de)元(yuan)件的(de)。
