Kev piav qhia ntawm qhov loj thiab lub zog ntawm lub tshuab hluav taws xob sib txawv li cas
Lub tshuab hluav taws xob hluav taws xob yog cov cuab yeej tseem ceeb hauv cov txheej txheem kho hluav taws xob, tab sis ntau tus neeg ua haujlwm saib xyuas uas nyuam qhuav ntsib cov hlau soldering tsis paub txog tus qauv uas siv los txiav txim siab lub zog ntawm cov hluav taws xob soldering hlau thaum lub sij hawm vuam, thiab lawv. nquag mus ncig lub ntiaj teb nrog ib tug soldering hlau. Qhov pom tseeb tshaj plaws yog tias cov nyhuv vuam yog subpar los ntawm kev tsis saib xyuas hauv kev xaiv lub zog hlau soldering.
Cov xov hlau luam tawm yuav poob tawm ntawm lub substrate thiab cov khoom siv tau yooj yim hlawv thaum lub zog ntawm cov hluav taws xob soldering hlau siab dhau (feem ntau, thaum qhov kub thiab txias ntawm diode thiab triode tshaj 200 degree, nws yuav hlawv tawm). Piv txwv li, thaum lub zog ntawm cov hlau soldering tsawg dhau lawm, cov tin soldering 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. Nws feem ntau yog siv los txuas cov kev sib txuas sib txuas, cov ntawv luam tawm Circuit Court boards, CMOS circuits, zoo nkauj transistors, IC recorders, TV teeb, thiab rau niaj hnub kev soj ntsuam Circuit Court (20W feem ntau yog txaus). Nws kuj yog siv los kho lub tshuab nqus tsev vacuum, xws li amplifiers thiab vintage instruments.Lub hwj chim tsim nyog yog 35W, thaum lwm hom cua sov yuav tsum tau 45W. Rau hom cua sov sab hauv thiab sab nrauv cua sov hom, cov xaim hluav taws xob loj loj rau vuam thiab cov kab hauv av ntawm cov hlau puag phaj yog 50W thiab 75W, feem. Siv cov hluav taws xob soldering hlau nrog cov cua sov sab nraud uas muaj ntau dua 100W yog tias koj xav tau cov khoom siv hlau. Cov neeg ua haujlwm hauv xov tooj cua muaj peev xwm, yog tias qhov xwm txheej tso cai, muab lawv tus kheej nrog 2OW cov cua sov sab hauv, 35W sab hauv lossis sab nraud cua sov hom, thiab 150W sab nraud cua sov hom hluav taws xob soldering hlau, tso cai rau lawv kom txaus siab ntau yam kev xav tau vuam.
Leaded solder, uas muaj ib tug muaj pes tsawg leeg ntawm 63 feem pua tin thiab 37 feem pua cov hlau lead thiab ib tug melting point ntawm 183 degree, yog hom solder uas feem ntau siv. Cov hlau tsis muaj txhuas, ntawm qhov tod tes, muaj cov ntsiab lus ntawm 99 feem pua tin thiab cov ntsiab lus flux ntawm ib ncig ntawm 1 feem pua, thiab nws cov ntsiab lus melting yog 227 degree. Lead solder muaj qhov zoo ntawm qhov tsis tshua muaj melting point, ua yooj yim rau solder, thiab pheej yig, tab sis nws tsis yog ecologically tus phooj ywg thiab txhuas txhuas muaj kev phom sij rau tib neeg, yog li koj yuav tsum ntxuav koj txhais tes kom huv si tom qab soldering. lub taub hau thiab lub vuam thaum vuam, nws yog qhov zoo tshaj rau hnav lub npog ntsej muag lossis nyob hauv thaj chaw uas muaj lub teeb ci. Cov hlau lead-dawb solder tau ua haujlwm nyob rau hauv cov tuam txhab rau lub tshuab vuam vim kev paub txog kev tiv thaiv ib puag ncig tau nce. Nws yog ib qho yooj yim to taub tias yog vim li cas cov hlau lead-dawb solder, uas feem ntau nyuaj rau yaj thaum kho cov khoom siv hluav taws xob txawv teb chaws, muaj qhov kub siab melting point.
Lub tshuab hluav taws xob hluav taws xob yog cov cuab yeej hluav taws xob cua sov uas, yog tias qhib, tuaj yeem tsim qhov kub ntawm kwv yees li 250 degree. Qhov tseeb, kev siv hluav taws xob tshwm sim thoob plaws hauv cov txheej txheem soldering thaum siv hluav taws xob soldering hlau. Lub solder absorbs lub tshav kub los ntawm lub soldering hlau taub thaum nws los rau hauv kev sib cuag nrog lub soldering nto, melts thiab ntws, thiab tsim ib tug kaj thiab ncig solder hlws ris vim nto nro. Cov hlau yog cov khoom siv hluav taws xob zoo, yog li thaum lub sij hawm vuam, kev hloov hluav taws xob tshwm sim sai dua.Qhov kub ntawm lub vuam yuav txo qis me ntsis thaum lub sij hawm melting txheej txheem raws li qhov tshwm sim ntawm tshav kub los ntawm cov hlau soldering. Lub solder hlws ris yuav tsum nqus cua sov ntau dua yog tias nws loj dua nyob rau hauv qhov chaw kom cov solder yaj. Qhov ntsuas kub qis dua sai dua yog tias lub taub hau hlau me me thiab khaws cov cua sov tsawg dua, thiab los ntawm lub sijhawm cua sov tsim tawm vim lub zog ntawm cov tub ntxhais hlau tsis muaj zog, nws lig dhau los ua kom cov cua sov uas tau ploj lawm. Lub solder tsis yaj los yog tsis yaj kiag li tam sim no yog qhov feem ntau cov laj thawj tshwm sim. Nyob rau hauv cov xwm txheej no, welding yuav tsum tau siv lub siab-lub zog soldering hlau. Xwb, yog hais tias cov welded qhov chaw me me, nws tsis yog yuav tsum tau siv ib tug high-power soldering hlau; Txawm li cas los xij, yog tias nws yog, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas lub sijhawm vuam vim tias cov cua sov ntau dhau tuaj yeem ua rau lub voj voog yooj yim los ntawm cov khoom siv tam sim no thiab cov khoom siv hluav taws xob, ua rau cov ntawv luam tawm tooj liab tawm tuaj. Tsis muaj qhov xav tau ntau npaum li cas; soldering hlau lub zog tshwj xeeb yog txaus. Txoj hauv kev yooj yim tshaj plaws los xaiv cov hlau nplaum uas haum rau koj yog saib xyuas cov neeg ua haujlwm kev ua haujlwm mus sij hawm ntev.
