Raws li qhov ua tau zoo hauv lub neej, kev hloov pauv yog tus yuam sij rau peb kev ua haujlwm thiab siv cov twj paj nruag thiab cov khoom siv hluav taws xob. Txhawm rau kov qhov hloov pauv tau ua haujlwm tiag tiag, nws yuav tsum dhau los ntawm ib qib, uas yog, vuam. Hauv cov txheej txheem ntawm kev txhim kho kev hloov pauv, yog tias qee tus kws tshaj lij tshiab tsis muaj kev nkag siab zoo txog kev hloov pauv thiab ua rau kev ua haujlwm tsis raug, poob ntawm qhov hloov pauv tseem yog qhov loj. Hauv tag nrho cov txheej txheem ntawm kev sim thiab vuam qhov hloov pauv, yog tias lub nra ntau dua tus nqi tshwj xeeb, qhov hloov pauv yuav raug puas tsuaj. Yog li ntawd, dab tsi yog qhov ceev faj rau vuam tact hloov? Thaum peb khaws lub kov hloov, sim kom tsis txhob muab nws tso rau hauv qhov chaw raug tshav ntuj lossis muaj cov roj xeb. Yog tias nws tau siv rau hauv ib puag ncig uas muaj cov pa roj carbon ntau, nws yuav ua rau muaj kev sib cuag tsis zoo thiab lwm yam tshwm sim. Tom ntej no, Kuv yuav muab cov lus piav qhia ntxaws txog kev ceev faj rau kev siv lub tshuab ua kom zoo.
Kov hloov
Nco tseg 1. Tiv thaiv kom tsis txhob ntws los ntawm ib puag ncig lub rooj tsav xwm luam tawm mus rau lub cev hloov dej.
Nco tseg 2: Cov txheej txheem vuam yuav tsum tau teeb tsa raws li qhov xwm txheej tsim khoom loj.
Nco tseg peb. Thaum soldering, dej-soluble flux yuav ua rau lub teeb kov kov. Thov tiv thaiv nws los ntawm kev sim.
Nco tseg 4: Lub teeb kov hloov nrog lub teeb yog ua haujlwm ncaj qha los ntawm tib neeg. Thov tsis txhob siv nws txhawm rau txheeb xyuas cov neeg kho tshuab.
Nco tseg 5. Rau txoj hauv kev txoj haujlwm ntawm cov khoom siv hauv Circuit board luam tawm, thov xa mus rau cov lus pom zoo teev tseg hauv daim duab qhia kev hloov pauv.
Nco tseg 6. Cov khoom lag luam nrog cov khoom siv ntsia hlau yuav tsum tau nqa tawm hauv qhov tshwj xeeb nruj nruj kom tiv thaiv kev puas tsuaj ntawm xov.
Nco tseg 7. Thaum siv qis qis qis (qis dua DC1V), tej zaum yuav muaj kev sib cuag tsis zoo. Thaum siv qhov xwm txheej no, thov lees paub cais.
Nco tseg 8. Thaum soldering lub davhlau ya nyob twg, yog tias siv lub nra rau lub davhlau ya nyob twg, yuav muaj qhov xoob, deformation thiab tsis zoo ntawm cov yam ntxwv hluav taws xob vim qhov xwm txheej sib txawv. Thov xyuam xim rau nws thaum mus sib hais.
Nco tseg 9. Lub vuam ua ntej kub ntawm qhov hloov pauv feem ntau pom zoo kom qis dua 100 ℃, thiab qhov ntsuas kub hauv vuam ua haujlwm yuav tsum tau tswj ntawm 260 ℃, thiab lub sijhawm tom qab vuam yuav tsum ua tiav hauv 3 vib nas this. Yog tias qhov hloov pauv Lub vuam lub sijhawm ntev dhau, thiab nws yooj yim ua rau lub davhlau ya nyob twg ko taw raug welded los lossis puas. Yog li ntawd, koj yuav tsum tau ceev faj ntau dua nyob rau lub sijhawm siv vuam thiab qhov kub vuam.
Nco tseg 10. Hauv cov txheej txheem ntawm kev rov ua haujlwm txuas lub vijtsam kov, koj yuav tsum tso tseg li peb feeb ntawm kev ua haujlwm thawj zaug thiab zaum ob, cia cov pob qij txha txuas ntawm qhov hloov pauv muaj cua sov txaus txaus, thiab tom qab ntawd rov qab mus rau qhov kub ua ntej ua haujlwm thib ob . Lub sij hawm vuam. Txwv tsis pub, txuas mus txuas ntxiv ntawm qhov kub thiab txias yuav yooj yim ua rau lub vuam taw ntawm qhov kov hloov mus deformed lossis puas. Yog li ntawd, ua kom ntseeg tau tias qhov kub thiab txias ib puag ncig tsim nyog thaum txheej txheem vuam.
