Qhia qhov sib txawv ntawm cov hlau soldering wattages
Nyob rau hauv cov txheej txheem kho hluav taws xob, cov hlau soldering yog ib qho khoom siv tsis tau, tab sis ntau ntawm kev sib cuag nrog cov neeg ua haujlwm kho cov hlau, tsis paub cov txheej txheem vuam raws li cov txheej txheem los xaiv lub zog ntawm cov hlau soldering, feem ntau yog cov hlau soldering. mus thoob qab ntuj. Qhov cuam tshuam ncaj qha tshaj plaws yog vim tsis xyuam xim rau qhov kev xaiv ntawm lub zog loj ntawm cov hlau soldering, uas ua rau qhov tsis zoo ntawm vuam cov txiaj ntsig.
Kev siv lub zog ntawm cov hlau nplaum loj heev, yooj yim rau hlawv cov khoom (feem ntau diode, triode hlws ris kub ntawm ntau tshaj 200 degree yuav raug hlawv) thiab ua rau cov ntawv luam tawm ntawm lub substrate; Kev siv lub zog ntawm cov hlau soldering yog me me, solder tsis tuaj yeem yaj tag nrho, flux tsis tuaj yeem volatilised tawm ntawm qhov taw tes soldering tsis du, tsis ruaj, yooj yim los tsim virtual vuam. Feem ntau, siv rau vuam integrated circuits, luam Circuit Court boards, CMOS circuits, hniav transistors, IC-type tape recorders, TVs, rau ib tug zoo tib yam Circuit Court sim, feem ntau 20W yog tsim nyog, kho lub tshuab nqus tsev raj, xws li gallbladder, qub twj paj nruag, 35W yog qhov tsim nyog, hom hluav taws xob sab nraud yog 45W, vuam loj hloov hluav taws xob thaiv, cov pob zeb hauv av ntawm cov hlau substrate, nws yog siv cov cua sov sab hauv 50W, sab nraud kub hom 75W. Yog tias koj xav tau cov khoom siv hlau, koj yuav tsum xaiv ntau tshaj 100W sab nraud kub soldering hlau. Yog tias cov xwm txheej tso cai, cov neeg nyiam siv xov tooj cua tuaj yeem nruab nrog 2OW endothermic, 35W endothermic lossis exothermic, 150W exothermic soldering hlau, uas ua tau raws li qhov xav tau ntawm ntau yam vuam.
Peb siv cov solder feem ntau muab faib ua cov hlau lead thiab tsis muaj hlau lead ob hom solder, tab sis feem ntau siv yog leaded solder, muaj pes tsawg leeg yog 63% tin, txhuas 37%, melting point 183 degree: thiab cov hlau lead-free solder muaj pes tsawg leeg yog 99% tin, flux txog li 1%, melting point 227 degree. Leaded solder muaj qhov zoo ntawm qhov tsis tshua muaj melting point, yooj yim rau welding, tsis tshua muaj nqi, tab sis tsis yog ib puag ncig tus phooj ywg, txhuas txhuas ua teeb meem rau tib neeg lub cev, yog li tom qab ua tiav ntawm vuam, nco ntsoov ntxuav koj txhais tes kom zoo, hauv cov txheej txheem vuam, Nws yog qhov zoo tshaj plaws los hnav lub npog ntsej muag, lossis qhov chaw ci ntsa iab, kom ntseeg tau tias lub taub hau thiab qhov vuam ntawm qhov deb. Nrog rau kev txhim kho ntawm tib neeg kev paub txog kev tiv thaiv ib puag ncig, tam sim no lub tshuab vuam hauv cov chaw tsim khoom siv cov hlau lead-free solder. Txij li thaum lub melting point ntawm lead-free solder yog siab dua, nws yog ib qho yooj yim to taub vim li cas nws yog ib qho nyuaj rau yaj lub solder thaum kho cov khoom siv hluav taws xob txawv teb chaws.
Lub tshuab hluav taws xob yog cov khoom siv hluav taws xob cua sov uas ua rau kub siab txog 250 degree thaum muaj zog. Soldering hlau nyob rau hauv cov txheej txheem vuam, yog qhov ua tau zoo ntawm cov txheej txheem kev sib cuag nrog lub vuam nto, lub taub hau ntawm lub taub hau ntawm cov cua sov hloov mus rau lub vuam, lub vuam absorbs lub tshav kub melting ntws thiab nyob rau hauv qhov kev txiav txim ntawm qhov nro, tsim. ntawm ib qho ci ci sib npaug sib koom ua ke. Nyob rau hauv cov txheej txheem welding thaum tshav kub kub conduction, vim hais tias cov hlau yog ib tug zoo conductor ntawm tshav kub, tshav kub hloov ceev. Solder melting txheej txheem, vim yog cov hlau ntsis ntawm cov cua sov poob, nws qhov kub thiab txias yog ntau dua los yog tsawg dua, yog hais tias qhov chaw soldering yog loj, yuav tsum tau nqus cua sov ntau dua kom nws saum lub solder mus txog qhov melting point. Yog hais tias lub taub hau ntawm lub taub hau yog me me, tsis tshua muaj cua sov cia, qhov kub thiab txias poob sai dua, vim yog lub zog ntawm cov tub ntxhais hlau me me hluav taws xob tsim los ntxiv qhov poob ntawm cov cua sov, qhov tshwm sim zoo tshaj plaws nyob rau lub sijhawm no yog lub solder tsis yaj lossis yaj. tsis tiav. Nyob rau hauv rooj plaub no, peb yuav tsum xaiv high-power soldering hlau rau vuam. Ntawm qhov tsis sib xws, yog tias cov khoom siv vuam me me, peb tsis tas yuav xaiv lub tshuab hluav taws xob siab; Yog tias koj siv lub tshuab hluav taws xob muaj zog, nco ntsoov ua tib zoo saib lub sijhawm vuam, txwv tsis pub cov cua sov ntau dhau yog yooj yim los ntawm qhov tam sim no ntws los ntawm txoj kev hu ua Circuit Court, Circuit Court board puas, uas ua rau cov luam ntawv ntawm cov ntawv ci tooj liab tawm. Tshwj xeeb npaum li cas lub zog siab soldering hlau yog qhov tsim nyog, tsis muaj qhov yuav tsum tau ua kom muaj nuj nqis, kev saib xyuas cov neeg ua haujlwm ntawm kev ua haujlwm ntev yog txoj hauv kev zoo tshaj plaws los xaiv txoj hauv kev zoo tshaj plaws kom haum rau lawv tus kheej soldering hlau.
