Yuav ua li cas siv hluav taws xob soldering hlau (tsim rau LED vuam)
1. Taw qhia txog hluav taws xob soldering hlau
1. Sab nraud cua sov hluav taws xob soldering hlau feem ntau yog tsim los ntawm lub taub hau ntawm lub taub hau, lub taub hau hlau, lub plhaub, lub kov, lub ntsaws thiab lwm yam. Lub taub hau ntawm lub taub hau yog ntsia rau hauv cov tub ntxhais hlau soldering thiab yog ua los ntawm cov khoom siv tooj liab nrog zoo thermal conductivity tooj liab raws li cov matrix. Qhov ntev ntawm lub taub hau hlau tuaj yeem hloov kho (qhov luv luv ntawm cov hlau taub hau, qhov siab dua qhov kub ntawm cov hlau taub hau), thiab muaj cov duab sib txawv xws li chisel, taw qhia lub khob hliav qab, puag ncig, lub voj voog, taw qhia lub khob hliav qab thiab ib nrab. -circular zawj kom haum Qhov xav tau ntawm qhov sib txawv vuam.
2. Internal cua sov hluav taws xob soldering hlau muaj tsib yam: txuas pas nrig, kov, caij nplooj ntoos hlav clip, soldering hlau core, thiab soldering hlau taub (tseem hu ua tooj liab taub hau). Cov tub ntxhais hlau soldering tau nruab rau hauv lub taub hau ntawm lub taub hau (heats sai, thiab cov thermal efficiency siab li 85 feem pua ~ feem pua). Cov tub ntxhais hlau soldering yog ua los ntawm npib tsib xee-chromium tsis kam hlau qhov txhab ntawm lub raj plooj (porcelain tube). Feem ntau, qhov tsis kam ntawm 20W hluav taws xob soldering hlau yog li 2.4kΩ, thiab ntawm 35W hluav taws xob soldering hlau yog li 1.6kΩ. Kev ua haujlwm kub ntawm cov khoom siv hluav taws xob siv hluav taws xob feem ntau muaj nyob rau hauv cov lus hauv qab no: Soldering hlau fais fab / W20, 25, 45, 75, 100 Terminal kub / degree 350, 400, 420, 440, 455 Feem ntau hais lus, ntau dua. lub zog ntawm cov hluav taws xob soldering hlau, qhov kub ntau dua, qhov kub ntawm qhov kawg ntawm cov hlau soldering. Vuam integrated circuits, luam Circuit Court boards, thiab CMOS circuits feem ntau siv 20W sab hauv cua sov hluav taws xob soldering hlau. Lub zog ntawm cov hlau nplaum siv yog siab dhau lawm, nws yooj yim rau scald cov khoom (feem ntau, thaum qhov kub thiab txias ntawm diode thiab triode tshaj 200 degree, nws yuav hlawv tawm) thiab cov xov hlau luam tawm yuav poob tawm ntawm lub substrate; Lub zog ntawm cov hlau siv yog me me, thiab cov hlau tsis tuaj yeem ua kom tiav, 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. Yog tias lub sijhawm vuam ntev dhau lawm, lub cuab yeej yuav raug hlawv. Feem ntau, txhua qhov sib koom ua ke ua tiav hauv 1.5 txog 4S.
3. Lwm yam soldering hlau
1) Qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau Lub taub hau ntawm qhov kub tsis tu ncua hluav taws xob hluav taws xob soldering hlau yog nruab nrog cov hlau nplaum-hom kub tswj los tswj lub zog ntawm lub sijhawm thiab ua tiav lub hom phiaj ntawm qhov kub thiab txias. Thaum lub soldering kub yuav tsum tsis txhob siab dhau heev lawm thiab lub sij hawm soldering yuav tsum tsis txhob ntev dhau lawm, yuav tsum tau siv ib tug qhov kub ntawm hluav taws xob soldering hlau, tab sis nws yog kim heev.
2) Tin-absorbing hluav taws xob soldering hlau Tin-absorbing hluav taws xob soldering hlau yog ib tug desoldering cuab tam uas integrates ib tug piston-hom tin absorber thiab ib tug hluav taws xob soldering hlau. Nws muaj cov yam ntxwv ntawm kev siv yooj yim, yoog raws, thiab kev siv dav dav. Qhov tsis zoo yog tias tsuas yog ib qho kev sib koom ua ke tuaj yeem raug tshem tawm ntawm ib lub sijhawm.
3) Steam soldering hlau Ib qho hlau uas kub hnyiab tau cov pa hluav taws xob xws li roj av liquefied thiab methane los ua kom sov cov hlau taub hau. Nws yog qhov tsim nyog rau qee lub sijhawm uas cov khoom siv hluav taws xob tsis yooj yim lossis tsis tuaj yeem muab AC lub zog.
Qhov thib ob, qhov kev xaiv ntawm hluav taws xob soldering hlau
1. Kev xaiv hluav taws xob soldering hlau feem ntau ua raws li cov hauv qab no:
① Cov duab ntawm cov hlau taub hau yuav tsum yoog raws li qhov xav tau ntawm cov khoom siv vuam thiab qhov sib dhos ntom ntom ntawm cov khoom.
② Qhov kub ntawm lub taub hau ntawm lub taub hau yuav tsum sib haum nrog lub melting point ntawm lub solder, uas feem ntau yog 30-80 degree siab tshaj qhov melting point ntawm lub solder (tsis suav qhov kub poob thaum lub soldering hlau taub kov. soldering point).
③ Lub peev xwm kub ntawm cov hlau soldering yuav tsum tsim nyog. Lub sij hawm rov qab los ntawm qhov kub thiab txias ntawm cov hlau soldering yuav tsum tau yoog raws li qhov yuav tsum tau ua ntawm qhov chaw ntawm qhov vuam. Lub sij hawm rov qab los ntawm qhov kub thiab txias yog hais txog lub sij hawm xav tau rau qhov kub ntawm qhov kawg ntawm lub taub hau ntawm lub taub hau kom rov qab mus rau qhov kub siab tshaj plaws tom qab qhov kub ntawm lub taub hau ntawm cov hlau soldering poob vim qhov kub poob thaum lub sij hawm soldering. Nws muaj feem xyuam rau lub hwj chim ntawm cov hluav taws xob soldering hlau, lub peev xwm ntawm cov cua sov, thiab cov duab thiab qhov ntev ntawm lub taub hau ntawm cov hlau soldering.
