Cov tsos ntawm cov twj paj nruag thiab cov ntsuas tsis zoo, qhov taw qhia yog qhov tseeb, kev nyeem ntawv yog qhov muag pom, thiab lawv nyob hauv lub neej ua haujlwm tsim nyog;
4. Lub vaj huam sib luag kev ua haujlwm thiab cov zaub yog qhov qub, cov nyees khawm tuav yog hloov tau thiab txhim khu kev qha, thiab lub computer tswj system ua haujlwm ib txwm;
5. Cov cuab yeej ua haujlwm tsis tu ncua sab hauv thiab sab nraud, tsis muaj lub tsho daj thiab cov roj stains.
Reflow soldering rauv
1. Qhov ntsuas kub tswj tau ua raws li cov lus qhia tshwj xeeb ntawm phau ntawv qhia, thiab kev tswj xyuas qhov tseeb yog nyob rau hauv ± 2.0 degree . 2. Kev tswj ceev ua raws li cov lus qhia tshwj xeeb ntawm phau ntawv qhia, thiab qhov tseeb yog tswj tsis pub dhau ±0.2m/min;
3. Qhov sib txawv ntawm qhov kub thiab txias ntawm lub substrate txav (tsawg dua lossis sib npaug ntawm 150 hli qhov sib nrug) yog nyob rau hauv ± 10.0 degree;
4. Cov tsos ntawm lub rhaub yog ua tiav thiab cov kev sib txuas hluav taws xob muaj kev ntseeg siab. Cov cua kub cua tshuab ua haujlwm zoo thiab tsis muaj suab nrov;
5. Cov kev taw qhia rails yog kho tau yooj yim thiab khaws cia rau tib lub sijhawm. Qhov dav dav ntawm conveying substrate ua tau raws li cov lus qhia ntawm phau ntawv;
6. Lub tshuab ua haujlwm ib txwm ua haujlwm, qhov zoo li ntawm cov cuab yeej thiab cov ntsuas ntsuas tsis zoo, qhov taw qhia yog qhov tseeb, kev nyeem ntawv yog qhov muag pom, thiab lawv nyob hauv lub neej ua haujlwm tsim nyog;
7. Cov khoom siv hluav taws xob tau ua tiav, cov kav dej tau npaj ua tiav, thiab kev ua haujlwm tau zoo thiab txhim khu kev qha
8. Cov cuab yeej ua haujlwm tsis tu ncua sab hauv thiab sab nraud, tsis muaj yellowing thiab roj stains.
Kev tshuaj xyuas thiab kev daws teeb meem ntawm cov laj thawj tseem ceeb ntawm kev cuam tshuam ntawm lub tshuab SMT, thiab kev txhim kho kev ua tau zoo Kev soj ntsuam ntawm cov laj thawj tseem ceeb rau kev cuam tshuam ntawm SMT tshuab
Hauv cov txheej txheem tsim khoom SMT, yuav ua li cas los tswj cov nqi tsim khoom thiab txhim kho kev tsim khoom yog qhov kev txhawj xeeb loj rau cov tswv lag luam thiab cov kws tsim khoom, thiab cov no muaj feem cuam tshuam nrog kev cuam tshuam ntawm SMT tshuab. Cia peb tham txog qhov teeb meem pov tseg ntawm lub tshuab SMT. Qhov hu ua ntuav yog hais txog lub tshuab SMT hauv cov txheej txheem tsim khoom. Tom qab nqus cov khoom, nws tsis lo, tab sis muab cov khoom pov tseg rau hauv lub thawv pov tseg lossis lwm qhov chaw, lossis ua ib qho kev cuam tshuam saum toj no yam tsis tau nqus cov khoom. Kev cuam tshuam ua rau cov khoom poob, ua rau lub sijhawm ntau lawm, txo cov kev ua tau zoo, thiab nce nqi ntau lawm. Txhawm rau txhim kho kev tsim khoom kom zoo thiab txo cov nqi, qhov teeb meem ntawm kev cuam tshuam siab yuav tsum tau daws.
