Thaum soldering ib yam dab tsi nrog hluav taws xob soldering hlau, yog vim li cas nws tseem nyuaj rau solder nrog rosin?
(1) Nws hais tias rosin yog flux. Thaum kuv solder ib yam dab tsi nrog hluav taws xob soldering hlau, vim li cas kuv thiaj siv tsis tau rosin rau solder? Thiab thaum kuv tsis siv rosin, lub solder muaj zog dua.
(2) Puas yuav siv 75 feem pua ntawm cawv los ntxuav lub rooj tsav xwm hauv Circuit Court ua rau muaj kev phom sij? Puas yog cov tin absorber siv thaum cov hlau kub kub? Yuav ua li cas tiv thaiv hluav taws xob soldering hlau los ntawm tig dub thiab oxidized?
Thawj qhov xwm txheej koj tau hais yog ua tau, tab sis nws tsis yog ib qho tshwm sim, txwv tsis pub yuav tsis muaj qhov zoo li rosin fluxing. Nws yog feem ntau hais txog seb qhov kub ntawm cov hluav taws xob soldering hlau puas haum (qhov zoo tshaj qhov kub yog 240-250 degree), qhov hnyav ntawm oxidation ntawm qhov chaw sib cuag, thiab qhov zoo ntawm cov hlau solder.
Nws tsis muaj teeb meem los siv 75 feem pua ntawm cawv los ntxuav lub rooj tsavxwm. Tsis txhob them tus nqi hluav taws xob. Nws yuav tsum tau ntxuav los yog qhuav rau lub sij hawm. Ib txhia yuav tawm me ntsis dawb cim, uas yuav tsis cuam tshuam rau kev siv. Lub tin absorber yog siv thaum lub solder sib koom yog melted, thiab nws yuav tsum tau zoo sib koom tes thiab ceev.
Oxidation ntawm cov hlau soldering tom qab siv ntev yog ib qho tshwm sim. Dai ib co tin thaum tsis siv, thiaj li ua kom lub ntsej muag kawg tsis yooj yim rau oxidize. Cov ntu yav tom ntej tuaj yeem polished. Yog tias koj muaj kev ua haujlwm ntau, koj tuaj yeem siv qhov chaw nres tsheb hluav taws xob thiab qhov ntsuas kub-hloov hluav taws xob hloov hluav taws xob kom tsis txhob muaj qhov kub-kub oxidation ntev thiab blackening.
Soldering hlau zog
Lub zog ntawm cov hluav taws xob hluav taws xob siv hluav taws xob yog qhov loj heev, nws yooj yim rau hlawv cov khoom (feem ntau, thaum qhov kub thiab txias ntawm diode thiab triode siab tshaj 200 degree, nws yuav hlawv tawm) thiab cov xov hlau luam tawm yuav poob ntawm lub substrate; Lub zog ntawm cov hlau siv yog me me heev, thiab cov khoom siv tsis tuaj yeem yaj tag nrho, cov flux tsis tuaj yeem hloov pauv, cov pob qij txha tsis du thiab ruaj khov, thiab nws yooj yim los tsim cov vuam cuav. - Feem ntau, lub zog ntawm cov hluav taws xob siv hluav taws xob siv rau vuam sib xyaw ua ke thiab cov kab luam tawm yog qhov loj heev, uas yooj yim rau hlawv cov khoom (feem ntau, thaum qhov kub thiab txias ntawm diode thiab triode tshaj 200 degree, nws yuav hlawv tawm) thiab cov ntaub ntawv luam tawm los ntawm Lub substrate ntog tawm; Lub zog ntawm cov hlau siv yog me heev, lub solder tsis tuaj yeem yaj tag nrho, cov flux tsis tuaj yeem hloov pauv, cov pob qij txha tsis du thiab ruaj khov, thiab nws yooj yim los tsim cov khoom cuav. - Feem ntau, nws yog siv rau kev sib txuas sib txuas, cov ntawv luam tawm hauv Circuit Court, CMOS circuits, kho kom zoo nkauj transistors, IC recorders, TV teeb, rau kev sim Circuit Court zoo tib yam, feem ntau 20W yog qhov tsim nyog, thiab kho lub tshuab nqus tsev vacuum, xws li amplifiers, qub- fashioned 35W yog haum rau cov twj paj nruag, 45W rau sab nraud cua sov hom, 50W rau lub internal cua sov hom thiab 75W rau lwm yam cua sov hom rau welding lub thaiv ntawm lub loj transformer thiab lub grounding trunk kab ntawm cov hlau puag phaj. Yog tias koj xav tau cov khoom siv hlau, koj yuav tsum siv lub tshuab hluav taws xob hluav taws xob sab nraud uas muaj zog tshaj 100W. Yog tias muaj kev tso cai, cov neeg nyiam siv xov tooj cua tuaj yeem nruab nrog 2OW cov cua sov sab hauv, 35W sab hauv cua sov lossis lwm hom cua sov, thiab 150W sab nraud cua sov hom hluav taws xob soldering hlau, kom nws tuaj yeem ua tau raws li ntau yam kev xav tau vuam.
