Wave soldering txawm tin ua rau thiab txoj kev kho mob

Wave soldering tshuabTxawm tias tin yog ib qho teeb meem tshwm sim hauv kev tsim cov khoom siv hluav taws xob plug-in yoj soldering, feem ntau yog vim cov nthwv dej soldering txawm tias tin tshwm sim los ntawm ntau yam laj thawj.Yog tias koj xav kho cov nthwv dej soldering kom txo tau cov tin, nws yog ib qho tsim nyog yuav tsum paub txog qhov ua rau yoj soldering txawm tias tin.Ntawm no los qhia cov laj thawj thiab ua cov tswv yim.

Wave soldering nrog tin ua rau.

1. Flux preheating kub yog siab dhau los yog tsawg dhau, feem ntau nyob rau hauv 100 ~ 110 degrees, preheating tsawg dhau, kev ua haujlwm flux tsis siab.Preheat siab dhau lawm, mus rau hauv tin steel flux tau ploj mus, tab sis kuj yooj yim rau txawm tin.
2. Tsis muaj flux lossis flux tsis txaus lossis tsis sib npaug, qhov nro ntawm lub xeev molten ntawm tin tsis tso tawm, ua rau yooj yim rau txawm tias tin.
3. Txheeb xyuas qhov kub ntawm lub cub tawg, tswj ntawm li 265 degrees, nws yog qhov zoo tshaj plaws los siv tus pas ntsuas kub los ntsuas qhov kub ntawm lub nthwv dej thaum lub yoj crest ntaus, vim tias qhov ntsuas kub ntawm cov cuab yeej yuav nyob hauv qab ntawm lub cub tawg. los yog lwm qhov chaw.Preheating kub tsis txaus yuav ua rau cov khoom tsis tuaj yeem ncav cuag qhov kub thiab txias, cov txheej txheem vuam vim yog cov khoom siv hluav taws xob nqus, ua rau cov hlau tsis zoo, thiab tsim cov tin.Tej zaum kuj yuav muaj qhov kub thiab txias ntawm lub cub tawg, los yog vuam ceev ceev heev.
4. Kev tshawb xyuas tsis tu ncua ua ib qho kev txheeb xyuas tin muaj pes tsawg leeg, nws muaj peev xwm ua tau tias tooj liab lossis lwm yam hlau cov ntsiab lus tshaj li tus qauv, ua rau txo qis kev txav ntawm cov tin, yooj yim los ntawm cov tin.
5. Kos lub kaum sab xis ntawm lub nthwv dej ntawm txoj kab, 7 degrees yog qhov zoo tshaj plaws, ib qho yooj yim rau dai tin.
6. IC thiab kab ntawm kev tsim tsis zoo, muab tso ua ke, plaub sab IC ntom taw qhov sib nrug <0.4mm, tsis muaj lub kaum sab xis rau hauv lub rooj tsavxwm.
7. PCB rhuab nruab nrab dab deformation tshwm sim los ntawm txawm tin.
8. Tin steel siab dhau lawm, tus thawj noj ntau tin, tuab heev, yuav tsum txawm.
9. Lub Circuit Court boards tsis yog tsim los ntawm lub solder dam, txuas tom qab luam ntawv ntawm lub solder paste;los yog Circuit Court board nws tus kheej yog tsim los kom muaj ib tug solder pas dej ua ke / choj, tab sis nyob rau hauv cov khoom tiav rau hauv ib feem los yog tag nrho tawm, ces kuj yooj yim rau txawm tin.

Wave soldering txawm txoj kev kho tin.

1. Flux tsis txaus los yog tsis txaus, nce qhov ntws.
2. United tin kom ceev qhov ceev taw tes, khiav lub kaum sab xis o point.
3. Tsis txhob siv 1 nthwv dej, nrog 2 nthwv dej ntawm ib nthwv dej, noj tin qhov siab tsis tas yuav tsum yog 1/2, tuaj yeem kov hauv qab ntawm lub rooj tsavxwm yog txaus.Yog hais tias koj muaj ib lub tais, ces lub tin nto nyob rau hauv lub tais hollowed tawm lub siab tshaj plaws nto yog zoo.
4. Seb lub rooj tsavxwm yog deformed.
5. Yog tias 2 nthwv dej ib zaug tsis zoo, nrog 1 nthwv dej punch, 2 nthwv dej qis qis qis kov cov pins ntawm nws, yog li koj tuaj yeem kho cov duab ntawm cov hlua khi, tawm ntawm qhov zoo.
