Khoos phib tawj hloov kho lossis ib qho kev nyiam rau xov tooj cua hluav taws xob feem ntau xav tau cov kev daws teeb meem uas tsis yog: piv txwv, kev lag luam ywj pheej ntawm cov ntawv luam tawm Circuit Court muaj peev xwm ua tiav cov haujlwm tshwj xeeb thiab, vim li ntawd, tsis muaj nyob rau ntawm kev ua lag luam dawb. Yog lawm, qhov no tsis yog qhov yooj yim ua, txawm li cas los xij, tsis muaj ib yam dab tsi uas tus neeg txhawb siab ua tsis tau.
Tsim nyog
- - textolite
- - nitro xim (ntawm qhov phem tshaj - ntsia thawv ntsia hlau)
- - tho kev nrog txoj kab uas hla 1 mm.
- - ferric tshuaj dawb

- - soldering hlau
Cov Lus Qhia
Kauj ruam 1
Kos cim rau cov khoom (ntu thiab ntu) ntawm cov tswj hwm yav tom ntej siv tus cwj mem.
Kauj ruam 2
Degrease saum npoo nrog acetone thiab pleev xim cov kab kev sib txuas nrog cov xim pleev xim nitro, lub cim tshwj xeeb lossis ntsia thawv ntsia thawv.
Kauj ruam 3
Ncuav cov tshuaj ferric chloride rau hauv lub thawv yas thiab tso cov PCB yav tom ntej rau 15 feeb (nws tuaj yeem ntev dua yog hais tias cov tshuaj tsis zoo dua).
Kauj ruam 4
Tshem tawm cov ntawv xov ntawm qhov kev daws teeb meem, nco ntsoov tias tsis muaj tooj liab lo rau nws (tshwj tsis yog rau ib qho zais hauv qab xim), so nws thiab qhuav nws.
Kauj ruam 5
Siv cov tshuaj acetone rau tshem tawm cov xim / cov kua roj vanish los ntawm pawg thawj coj.
Kauj Ruam 6
Tho qhov uas koj xav tau, solder qhov koj xav tau, thiab siv koj tus kheej PCB.
