Hauv kev tsim khoom lossis kho ntawm cov khoom siv hluav taws xob, kev tsim nyog kom haum yog qhov kev mob tseem ceeb rau lawv ua haujlwm kom ntseeg tau. Thiab yog tias soldering resistors thiab capacitors yog qhov yooj yim, ces qee cov kev cai tseem ceeb yuav tsum tau ua thaum soldering transistors.
Cov Lus Qhia
Kauj ruam 1
Rau soldering cov khoom siv hluav taws xob, xaiv cov hlau soldering nrog lub zog tsis tshaj 60 watts, lub zog zoo yuav yog 40 watts. Zom lub hau ntawm cov hlau soldering kom nws loj me tso cai rau koj mus muag ib tus neeg ob txhais ceg ntawm qhov me me transistors. Cov hniav dav dav yog yooj yim heev 3-3.5 hli. Nws yog qhov tsim nyog kom muaj ob peb soldering irons, sib txawv hauv lub hwj chim thiab lub ntsej muag kom nruj.

Soldering bipolar transistors tsis tas yuav muaj kev ceev faj tshwj xeeb. Txawm li cas los xij, sim tsis txhob overheat lawv cov davhlau ya nyob twg, lub sijhawm rau cov hlau soldering mus kov lub transistor ceg yuav tsum tsis pub tshaj 3-4 vib nas this. Yog hais tias koj ham qhov transistor tsis muaj lub punched ib, rhaub qhov rau cov davhlau ya nyob twg nrog hlau soldering nyob rau hauv lem thiab ua qhov nyob rau hauv lub molten solder nrog rab koob. Ua tib zoo ntxig cov ceg ntawm transistor rau hauv lub qhov tsim thiab solder txhua ceg.
Kauj ruam 3
Ua tib zoo saib kom zoo ntawm qhov ua tau zoo ntawm soldering. Nrog cov sib "soldering" txias, uas yog, soldering nrog qhov kub tsis txaus ua rau kub muag, nws nteg hauv qhov tsis xwm yeem, hauv hauv qog, thiab muaj xim tsaus xim. Yog tias cov ntaub qhwv ib ncig ntawm lub txhuas tsis yog tinned lossis oiled, qhov muag yuav tsis pw ncaj nraim. Yog li no, ua ntej soldering, tin lub ncoo cuag, nws yuav tsum tau them nrog nyias, txawm txheej ntawm ham.
Kauj ruam 4
Siv rosin-cawv tov ua qhov flux. Txhawm rau npaj lub flux, coj lub raj mis me me ntawm ntsia thawv polish, nws yooj yim heev nrog lub ntsej muag txhuam. Crumble ib nrab ntawm lub rosin rau hauv nws thiab sau nws nrog ethyl cawv. Tos rau rosin kom yaj. Thaum ua haujlwm, maj mam thov cov flux nrog txhuam mus rau qhov chaw soldering.
Kauj ruam 5
Soldering teb effect transistors yuav tsum muaj kev tiv thaiv tshwj xeeb. Cov transistors no ntshai cov hluav taws xob zoo li qub, koj tuaj yeem rhuav tshem lawv los ntawm kov ib qho ntawm cov txuas nrog koj txhais tes. Lub cav soldering yuav tsum tau ua hauv av, cuam tshuam nws los ntawm lub ntsiab thaum soldering. Kov ib tug hluav taws xob hlau uas txua ua ntej kov cov transistor. Qhov zoo dua, muab txoj hlua tes rau ntawm koj lub dab teg uas txuas nrog rau hauv av - piv txwv li, khoom siv duab hluav taws xob.
Kauj Ruam 6
Ua ntej soldering, chwv tus hu rau ntawm lub Rooj Tswjhwm Saib nrog lub xov tooj soldering hlau thiab xwb ces ntxig rau transistor. Coj cov transistor los ntawm rooj plaub. Qhwv nyias tus xov hlau nyob ib ncig ntawm ob txhais ceg ua ntej soldering. Ntev npaum li ob txhais ceg ntawm transistor tau sib txuas ua ke, hluav taws xob zoo li qub tsis hem nws. Tom qab soldering, maj mam unscrew tus hlau nrog tweezers thiab tshem tawm. Hloov cov hlau, koj tuaj yeem siv ib daim ntawv ntawm cov zaub mov zoo li qub: hno nws nrog ob txhais ceg ntawm transistor, tom qab ntawd, tom qab soldering, tshem tawm. Nco ntsoov tias tsis muaj daim ntawv ntawm cov ntawv ci sab laug ntawm cov hlau lead.
