hom teeb meem thiab cov kev daws teeb meem ntawm cov txheej txheem tswj kev xa xov

1, lub kaw lus parting tswj system Cheebtsam offset;
Kev Ua Taug Kev Zaum: Kev kho cov nplai ua haujlwm, thaum hnyav, feem tivthaiv tus pin tsis nyob ntawm lub ncoo.
Ua rau: thaj zaj duab xis tawm ntawm cov nyiaj ntawm cov kua nplaum tsis sib xws (piv txwv li chip lub ob qho ntawm cov kua nplaum ib qho ntau dua ib qho), thaj thaum cov hloov pauv, thaj nplaum quab yuam txo qis, tom qab tus ciav PCB tso lub sijhawm ntev dhau kua nplaum semi-kho.
Kev daws: Txheeb xyuas cov kua nplaum ntawm lub tog raj rau txhaws, tshem tawm qhov tsis sib xws ntawm cov kua nplaum, kho cov xwm txheej ua haujlwm ntawm lub tshuab ua haujlwm, hloov cov kua nplaum, ntau npaum li cas tom qab lub sijhawm PCB tso yuav tsum tsis txhob siv sijhawm ntev dua (tsawg dua 4h).
2, koob tshuaj tiv thaiv kab mob tom qab kho cov khoom tivthaiv tus pin ntab / txav;
Kev Tshaj Tawm: Tom qab kho qhov kev tivthaiv pins ntab lossis hloov, cov khoom siv tin yuav nkag rau hauv ncoo tom qab kev vuam tas, thaum muaj mob loj ntawm luv Circuit Court thiab qhib Circuit Court.
Cov Ua: thaj tsis ncaj thaj zaj duab xis, ntau zaj duab xis thaj, thaj thaum cov tivthaiv offset.
Kev daws: Kho qhov kev txiav txim ntawm cov txheej txheem dosing, tswj cov nyiaj ntau npaum li cas, kho cov ntsuas ntawm cov txheej txheem thaj.
3, kev tswj hwm kev tswj hwm kom rub cov hlau / txuas hlua tw;
Kev pom qhov tshwm sim: Cov kev tsis xws luag hauv xaim / tailing thiab dosing.
Cov ua rau: sab hauv lub cheeb ntawm lub nplaum lub qhov ncauj tseem tsawg dhau, coj mus rhaub lub siab dhau, lub suab dhau ntawm cov nplaum los ntawm PCB loj heev, cov nplaum tso tawm lossis qhov zoo tsis zoo, zaj duab xis viscosity yog siab dhau, tom qab tshem tawm hauv lub tub yees tsis tuaj yeem rov qab mus rau chav sov, qhov nyiaj kua nplaum ntau dhau.
Kev daws: hloov sab hauv taub ntawm lub taub loj dua, txo cov tshuaj dosing qhov siab, kho" nres" qhov siab, hloov cov kua nplaum, xaiv qhov tsim nyog rau viscosity ntawm kua nplaum, tshem tawm los ntawm lub tub yees yuav tsum rov qab mus rau chav kub (txog 4h), kho qhov ntau npaum li cas ntawm kev noj tshuaj.
4, kev tswj hwm kev noj tshuaj zoo kua nplaum lub qhov ncauj txhaws;
Qhov ua tau: qhov ntau ntawm lub qhov ncauj kua nplaum yog qhov tsawg dua nyob tsis muaj cov kua nplaum tawm.
Cause: tsis tag ntxuav nyob rau hauv lub pinhole, thaj zaj duab xis tov nrog impurities, muaj lub qhov tshwm sim, tsis sib xws kua nplaum sib tov.
Kev daws: hloov cov koob huv, hloov zoo dua zaj duab xis thaj, thaj zaj duab xis naj npawb yuav tsum tsis raug yuam kev.
5, kev tswj hwm kev noj tshuaj yog qhov khoob;
Kev Ua Pauv: Tsuas yog ua cov koob tshuaj, tsis muaj npaum li cas ntawm kua nplaum.
Cause: sib xyaw ua npuas, kua nplaum kaw qhov ncauj.
Kev daws: Cov kua nplaum hauv cov phwj yuav tsum tau de-bubbled (tshwj xeeb tshaj yog nws tus kheej kua nplaum), raws li cov kua nplaum lub qhov ncauj thaiv txoj kev.
6, qhov taw tes tswj qhov system curing, tivthaiv sib txuas lub zog tsis txaus, qhov vuam vuam yuav poob qis;
Kev tawm tsam: tom qab kho cov khoom sib xyaw ua ke lub zog tsis txaus, qis dua tus nqi teev tseg, qee zaum los ntawm kov tes yuav tshwm sim nti.
Cov ua rau: tom qab kho cov txheej txheem tsis dhau nyob rau hauv qhov chaw, tshwj xeeb yog qhov kub tsis txaus, qhov feem cuam loj dhau lawm, kev nqus cua sov yog loj, lub teeb curing lub teeb laus, kua nplaum tsis txaus, cov tivthaiv / pcb yog paug.
Kev daws: Kho qhov cure kev kho mob, tshwj xeeb kom nce qhov kub ntawm qhov txias, feem ntau yog qhov siab tshaj plaws qhov kub ntawm lub ntsej muag thermo-curing yog qhov tseem ceeb heev, ncav lub ncov kub yuav yooj yim ua rau nti nti. Rau cov yees duab-kho cov kua nplaum, nws yuav tsum tau saib seb lub teeb ci-kho lub teeb ci yog kev laus, seb lub teeb ci yog lub qhov tsaus, qhov nyiaj ntawm kua nplaum, qhov cuam tshuam / pcb puas sib kis.
Qhov saum toj no yog rau kev noj tshuaj tiv thaiv txheej txheem ntawm cov teeb meem thiab cov kev daws teeb meem, tsuas yog rau koj qhov siv xwb.
