Nyob rau hauv xyoo tas los no, kev loj hlob sai ntawm cov khoom siv hluav taws xob, IC integrated circuit technology, ntau thiab ntau miniaturization ntawm cov khoom siv hluav taws xob, precision, cov khoom siv hluav taws xob hauv lub rooj tsav xwm tseem ceeb tau txais me thiab me. Thiab cov khoom nyob rau hauv xws li cov khoom muaj ntau inclined rau ntim, yog li muaj ib tug loj tus naj npawb ntawm IC, BGA thaj thov. Xws li IC pins ntau dua, qhov zoo dua, ntom dua, thiab zoo li BGA thiab CPU thiab lwm hom IC yog hemispherical, thiab nyob rau hauv qab txoj hauj lwm, los ntawm lub qhov muag dag tsuas tsis pom qhov zoo tom qab reflow soldering. Yog li ntawd, txhawm rau txheeb xyuas qhov zoo ntawm cov ICs, X - ray tshuab tshuaj xyuas cov cuab yeej yuav tsum tau siv, yog li X - RAY tau tsim sai heev nyob rau xyoo tas los no.
Kev kuaj pom ua ntejreflowqhov cubyog yeej nqa tawm manually los yogAOItshuab, uas tuaj yeem ntes cov IC niaj hnub (xws li QFP / SOP) cov khoom siv zoo, vim tias cov pins ntawm cov ICs raug nthuav tawm sab nraud, AOI tuaj yeem kuaj xyuas qhov zoo, thiab nrog cov pins hauv qab ntawm IC, sab hauv (xws li. Raws li BGA / QFN), AOI thiab phau ntawv liab qab qhov muag tsis tuaj yeem ntes nws cov khoom zoo, yog li nws yuav tsum tau siv X - Ray, los ntawm X - ray nkag mus ntawm qhov tsim ntawm qhov chaw los txiav txim seb lub pob solder puas yog welded, tsis muaj qhov cuav solder solder thiab lwm yam teeb meem tsis zoo.
1. Cov txheej txheem vuam tsis raug kuaj xyuas qhov kev pab cuam ntawm 98%, tshwj xeeb tshaj yog qhov zoo ntawm X - rays ntawm BGA, CSP thiab lwm yam solder pob qij txha zais cov cuab yeej tshuaj xyuas.
2. Kev txheeb xyuas ntau yam, kev pabcuam dav dav, kev tshawb nrhiav ua ntej ntawm cov khoom zoo: Yog tias PCBA raug txiav txim siab ua yuam kev, xav tias PCB sab hauv cov txheej txheem kev sib raug zoo tawg, X - ray tuaj yeem tshawb xyuas sai, lossis BGA / CSP thiab lwm yam ntaub ntawv ua ntej kuaj pom qhov tsis zoo. , kom tsis txhob muaj cov khoom tsis zoo rau hauv cov kab ntau lawm, ua rau rov ua haujlwm dua, pov tseg ntawm cov neeg ua haujlwm thiab cov khoom siv, thiab lwm yam.
3. Muaj kev ruaj ntseg siab dua, kev ntseeg siab ntawm kev kuaj xyuas qhov tsis xws luag, xws li: sab hauv cov khoom siv hluav taws xob tsis raug, lub qhov cua thiab cov pwm tsis zoo.
X - ray muaj ntau qhov zoo, tab sis tseem muaj qee qhov tsis zoo, piv txwv li, vim tias X - ray muaj cov hluav taws xob hluav taws xob, tsis tuaj yeem teeb tsa kev tshawb nrhiav hauv online, xav tau kev sib cais X - RAY chav kuaj, ces koj yuav tsum tau tawm. - kab kev xeem, yog tias nws yog ntau qhov kev txiav txim, lub peev xwm yuav tsis tuaj yeem khaws cia, tsis tuaj yeem lav kev xa khoom, thiab lwm yam.. Yog li ntawd, kev siv X - RAY yuav tsum tau ua raws li qhov tseeb ntawm cov khoom. , cov neeg siv khoom xav tau los txiav txim siab seb yuav siv.
