AOI檢(jian)測(ce)(ce)設備主要應用(yong)于SMT回(hui)流焊(han)前和SMT回(hui)流焊(han)后，AOI設備可檢(jian)測(ce)(ce)元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)多錫(xi)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)少(shao)錫(xi)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)錯件(jian)(jian)(jian)(jian)(jian)(jian)(jian)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)缺件(jian)(jian)(jian)(jian)(jian)(jian)(jian)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)偏(pian)移、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)翻件(jian)(jian)(jian)(jian)(jian)(jian)(jian)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)破損、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)虛焊(han)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)冷(leng)焊(han)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)空焊(han)、元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)極(ji)性反等(deng)等(deng)元(yuan)器(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)貼片(pian)缺陷(xian)。在(zai)(zai)線(xian)(xian)(xian)AOI自(zi)動光學檢(jian)測(ce)(ce)設備與離(li)線(xian)(xian)(xian)AOI自(zi)動光學檢(jian)測(ce)(ce)設備有什(shen)么不(bu)(bu)同(tong)？　　離(li)線(xian)(xian)(xian)AOI主要一(yi)(yi)(yi)個(ge)人(ren)(ren)去操作，檢(jian)測(ce)(ce)分為兩種(zhong)(zhong)：一(yi)(yi)(yi)種(zhong)(zhong)是(shi)抽檢(jian)，一(yi)(yi)(yi)種(zhong)(zhong)是(shi)全檢(jian)。現在(zai)(zai)一(yi)(yi)(yi)個(ge)工(gong)人(ren)(ren)工(gong)資大概在(zai)(zai)4千左(zuo)右， 一(yi)(yi)(yi)個(ge)人(ren)(ren)一(yi)(yi)(yi)年下(xia)來(lai)就要將(jiang)近5萬(wan)，一(yi)(yi)(yi)臺在(zai)(zai)線(xian)(xian)(xian)AOI至少(shao)可以省1-2個(ge)人(ren)(ren)工(gong)，一(yi)(yi)(yi)年可以省將(jiang)近10萬(wan)元(yuan)的(de)工(gong)資。這(zhe)是(shi)一(yi)(yi)(yi)筆不(bu)(bu)多不(bu)(bu)少(shao)的(de)開支，相當于一(yi)(yi)(yi)臺離(li)線(xian)(xian)(xian)AOI設備 的(de)錢還要多！

隨著接點(dian)數(shu)(shu)的(de)(de)(de)(de)增(zeng)(zeng)多(duo)，測(ce)試(shi)(shi)編(bian)程(cheng)和(he)(he)(he)針床夾(jia)具的(de)(de)(de)(de)成本也呈指(zhi)數(shu)(shu)倍數(shu)(shu)上(shang)升(sheng)。開發(fa)(fa)測(ce)試(shi)(shi)程(cheng)序和(he)(he)(he)夾(jia)具通常(chang)需(xu)要(yao)幾個星(xing)期的(de)(de)(de)(de)時間，更復雜的(de)(de)(de)(de)線路(lu)板可能還要(yao)一個多(duo)月。另外(wai)，增(zeng)(zeng)加ICT接點(dian)數(shu)(shu)量會導致ICT測(ce)試(shi)(shi)出錯和(he)(he)(he)重測(ce)次數(shu)(shu)的(de)(de)(de)(de)增(zeng)(zeng)多(duo)。AOI技術則不存在(zai)上(shang)述(shu)問(wen)題，它不需(xu)要(yao)針床，在(zai)計算(suan)機程(cheng)序驅動(dong)下，攝像(xiang)頭分區域自動(dong)掃描PCB，采集(ji)圖像(xiang)，測(ce)試(shi)(shi)的(de)(de)(de)(de)焊點(dian)與數(shu)(shu)據庫中的(de)(de)(de)(de)合格的(de)(de)(de)(de)參數(shu)(shu)進行(xing)比較，經(jing)過圖像(xiang)處理，檢查出PCB上(shang)缺陷。極短(duan)的(de)(de)(de)(de)測(ce)試(shi)(shi)程(cheng)序開發(fa)(fa)時間和(he)(he)(he)靈活性是(shi)AOI的(de)(de)(de)(de)優點(dian)。

隨著電子技(ji)(ji)術(shu)的(de)飛速發(fa)(fa)展，AOI檢(jian)(jian)測(ce)(ce)(ce)機，SMT技(ji)(ji)術(shu)越(yue)(yue)(yue)來(lai)(lai)越(yue)(yue)(yue)普(pu)及(ji)，芯(xin)片的(de)尺寸越(yue)(yue)(yue)來(lai)(lai)越(yue)(yue)(yue)小，芯(xin)片的(de)管腳(jiao)越(yue)(yue)(yue)來(lai)(lai)越(yue)(yue)(yue)多(duo)，尤其是(shi)(shi)近幾年(nian)出現的(de)BGA芯(xin)片。由(you)于BGA芯(xin)片的(de)引腳(jiao)不(bu)是(shi)(shi)按照常(chang)規設計(ji)分布在四周(zhou)，而(er)是(shi)(shi)分布在芯(xin)片底(di)部，因此(ci)傳統的(de)人工(gong)(gong)視(shi)覺(jue)檢(jian)(jian)測(ce)(ce)(ce)無(wu)(wu)法判(pan)斷(duan)焊點(dian)的(de)質(zhi)量，必須通過ICT功能(neng)測(ce)(ce)(ce)試。但一般來(lai)(lai)說，如果出現批次誤差，是(shi)(shi)無(wu)(wu)法及(ji)時發(fa)(fa)現和調(diao)整的(de)，人工(gong)(gong)視(shi)覺(jue)檢(jian)(jian)測(ce)(ce)(ce)是(shi)(shi)不(bu)準(zhun)確和重復(fu)性高的(de)技(ji)(ji)術(shu)。由(you)此(ci)，X射線檢(jian)(jian)測(ce)(ce)(ce)技(ji)(ji)術(shu)越(yue)(yue)(yue)來(lai)(lai)越(yue)(yue)(yue)廣泛地(di)應用于SMT回流焊的(de)質(zhi)量檢(jian)(jian)測(ce)(ce)(ce)，不(bu)僅能(neng)對(dui)焊點(dian)進(jin)行定(ding)性和定(ding)量分析，還(huan)能(neng)及(ji)時發(fa)(fa)現故(gu)障并做出調(diao)整。
