Taw qhia txog kev xaiv hluav taws xob soldering hlau
Thaum peb siv hluav taws xob soldering hlau los vuam cov khoom siv hluav taws xob, peb puas xav tias tsis txaus vim qhov ua haujlwm tsis zoo lossis tsim cov hlau soldering? Koj puas tau ua qhov muag tsis pom kev pe hawm 'txoj kev kaj 936' thaum mloog cov lus qhia ntawm ntau tus vajtswv zoo?
(1) Kev xaiv hluav taws xob soldering hlau hom
1. Internally rhuab hluav taws xob soldering hlau. Cov cua sov sab hauv hluav taws xob soldering hlau muaj cov qauv yooj yim, kev ua haujlwm siab thermal, thiab yog lub teeb yuag thiab hloov tau, ua rau nws nyiam xaiv. Nws muaj cov hlua txuas, kov, lub caij nplooj ntoos hlav clip, soldering hlau core, thiab soldering hlau taub hau (tseem hu ua tooj liab taub hau). Lub soldering hlau core yog ntsia rau hauv lub taub hau soldering hlau. Cov tub ntxhais hlau soldering yog ua los ntawm nickel chromium tsis kam xaim qhwv ib ncig ntawm lub raj plooj (porcelain tube). Feem ntau, qhov tsis kam ntawm 20W hluav taws xob soldering hlau yog li 2.4k Ω, thaum lub 35W hluav taws xob soldering hlau yog li 1.4k Ω.

2. Externally rhuab hluav taws xob soldering hlau. Hom hluav taws xob soldering hlau no muaj cov txheej txheem tsim khoom, tsis tshua muaj txiaj ntsig, thiab tus nqi siab, feem ntau suav nrog cov hlau taub hau, cov tub ntxhais hlau soldering, plhaub, kov, 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 raws li tooj liab nrog zoo thermal conductivity.
Qhov ntev ntawm lub taub hau hlau tuaj yeem hloov kho (qhov luv luv ntawm lub taub hau ntawm lub taub hau, qhov kub ntawm lub taub hau hlau soldering ntau dua). Cov duab uas nquag siv hauv kev xyaum suav nrog chisel, taw qhia lub khob hliav qab, lub ntsej muag ncig, lub voj voog, taw qhia lub khob hliav qab, thiab lub voj voos semicircular kom tau raws li qhov xav tau ntawm cov vuam sib txawv.

3. Thermostatic hluav taws xob soldering hlau. Nruab ib lub tshuab ntsuas kub sib nqus hauv lub taub hau ntawm lub taub hau kom tswj tau lub zog ntawm lub sijhawm, uas yog qhov kub thiab txias ntawm hluav taws xob soldering hlau. Thaum welding Cheebtsam uas yuav tsum tsis txhob kub kub los yog ntev heev nyob rau hauv vuam lub sij hawm, ib tug tas mus li kub hluav taws xob soldering hlau yuav tsum tau siv, tab sis nws cov nqi yog siab. Txawm hais tias qhov tsis siv neeg qhov kub thiab txias tsis siv neeg vuam hlau muaj ntau qhov chaw, nyuaj rau kev kho, thiab muaj tus nqi siab, nws tuaj yeem ua kom zoo ntawm cov pob qij txha, tshwj xeeb tshaj yog thaum ua cov kev sim hauv Circuit Court thiab kho cov ntawv luam tawm ntau, nws ua haujlwm zoo heev. zoo. Lub tshuab hluav taws xob siv hluav taws xob siv rau ntawm cov kab ntau lawm tau txais kev tswj hwm qhov hluav taws xob tsis siv neeg rau qhov kub thiab txias, uas yuav ua rau cov nqi qis dua. Hauv qee qhov chaw, cov khoom siv hluav taws xob tsis ruaj khov, thiab cov hlau nplaum feem ntau raug hlawv yam tsis muaj dipping hauv tin, lossis qhov kub tsis txaus rau solder. Txhawm rau kom ntseeg tau qhov zoo ntawm brazing, tib txoj kev xaiv yog siv qhov tsis siv neeg qhov kub thiab txias series soldering hlau los yog teeb tsa lub zog tswj qhov system. Txawm hais tias qhov kub thiab txias siab dhau lawm, cov txheej txheem kauj ruam-down resistor kuj tseem siv tau.

4. Tin absorbing hluav taws xob soldering hlau. Tin suction hluav taws xob soldering hlau yog cov cuab yeej soldering uas sib txuas ua ke piston hom tin suction ntaus ntawv nrog cov 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 ib zaug.

5. Gas vuam soldering hlau. Nws yog ib hom ntawm cov hlau uas siv cov roj combustible xws li roj liquefied thiab methane los hlawv thiab kub lub taub hau. Nyob rau hauv cov xwm txheej uas cov khoom siv hluav taws xob tsis yooj yim lossis AC fais fab tsis tuaj yeem muab tau, koj tuaj yeem xaiv siv nws. Vim muaj kev pheej hmoo ntawm kev tawg, kab lus no tsis tham txog kev xaiv ntawm cov hlau soldering ntawm no.
(2) Kev xaiv fais fab ntawm cov hluav taws xob soldering hlau
Lub zog ntawm cov hlau nplaum siv yog siab dhau lawm, uas tuaj yeem hlawv cov khoom tau yooj yim (feem ntau yog thaum qhov kub ntawm qhov sib txuas ntawm lub transistor thiab transistor siab tshaj 200 degree, nws yuav kub hnyiab tau) thiab ua rau cov xov hlau luam tawm kom tshem tawm ntawm lub substrate. ; Lub zog ntawm cov hlau soldering siv tsawg dhau, cov tin soldering tsis tuaj yeem yaj tag nrho, cov flux tsis tuaj yeem evaporate, cov pob qij txha tsis du thiab ruaj khov, thiab nws yog qhov ua rau tsis muaj tseeb. Feem ntau, nws yog siv rau vuam integrated circuits, luam Circuit Court boards, CMOS circuits, decorating transistors, IC hom recorders, TVs, thiab ua tej yam zoo tib yam Circuit Court sim. Nws feem ntau pom zoo kom siv 20W. Rau kev kho cov tshuab nqus tsev vacuum xws li tshuab biliary thiab cov cuab yeej qub, nws raug nquahu kom siv 35W, thaum rau cov cua sov sab nraud, nws raug nquahu kom siv 45W. Rau vuam cov xaim ntawm cov hloov pauv loj thiab cov kab hauv av tseem ceeb ntawm cov hlau substrates, nws raug nquahu kom siv cov khoom siv hluav taws xob sab hauv 50W, rhuab sab nraud 75W, thiab qee qhov kev siv hluav taws xob ntau dua.
Muaj ntau cov duab ntawm cov hlau taub hau, thiab qhov tseem ceeb ntawm kev xaiv ib qho yog kom tsis tu ncua muaj qee yam ntawm cov solder, sai thiab zoo yaj lub solder ntawm qhov sib koom ua ke, tsis tsim cov pob qij txha, sib tshooj, lossis dai, tsis muaj burrs, thiab tsis muaj. ua puas lub rooj tsavxwm thiab cov khoom. Yog tias cov pob qij txha ntawm lub tshuab yog cov khoom tshiab thiab ci, cov tin dipping seem ntawm lub taub hau hlau tuaj yeem loj dua, thiab lub taub hau tiaj tus lossis elliptical tuaj yeem siv rau kev hloov pauv ceev ceev, kev ua haujlwm zoo, thiab yooj yim. Lub tin oxide txheej yog tuab, thiab lub taub hau hlau yog qhov ntse, ua rau nws yooj yim tawg.
Vim tias lub siab ntom ntom ntawm Cheebtsam, nws yog ib qho tsim nyog yuav tsum tau siv cov hlau ntse sib raug zoo kom tsis txhob hlawv thiab soldering. Thaum sib sau ua ke thiab disassembling IC blocks, tshwj xeeb zoo li tus soldering hlau taub hau feem ntau siv. Qee lub sij hawm, vim tsis muaj peev xwm solder thiab xav tau kom tsis txhob ua kom puas cov khoom yas, khoov lub taub hau hlau siv. Tau kawg, nws kuj nyob ntawm txhua tus neeg txoj kev ua haujlwm thiab kev nyiam ua haujlwm.
Yuav ua li cas xaiv ib qho hluav taws xob soldering hlau
1. Kev xaiv cov txheej txheem cua sov raws li hluav taws xob soldering hlau
(1) Kev xaiv cov cua sov sab hauv thiab sab nraud: Thaum lub zog zoo ib yam, qhov kub ntawm cov cua sov sab hauv hluav taws xob hluav taws xob yog siab dua li ntawm cov cua sov sab nraud hluav taws xob soldering hlau.
(2) Thaum qhov kub tsis tshua muaj vuam yuav tsum tau siv, lub tshuab hluav taws xob yuav tsum tau siv los tswj qhov kub ntawm cov hluav taws xob soldering hlau. Qhov kub ntawm hluav taws xob soldering hlau yog ze ze rau lub hwj chim mov voltage. Hauv kev siv tswv yim, qhov kub ntawm cov hluav taws xob soldering hlau feem ntau txo qis los ntawm kev txo cov hluav taws xob hluav taws xob.
(3) Tswj qhov kub thiab txias los ntawm kev kho qhov ntev ntawm lub taub hau soldering.
(4) Muaj ntau txoj hauv kev los tswj qhov kub thiab txias ntawm cov hluav taws xob soldering hlau: txhim kho cov khoom siv hluav taws xob tswj kom tsis txhob muaj kev hloov pauv hauv lub zog hluav taws xob; Khaws ib qho ntim, qhov ntev, thiab cov duab ntawm lub taub hau hlau soldering; Siv lub ntsuas kub tsis tu ncua hluav taws xob soldering hlau; Khaws qhov kub thiab txias hauv tsev; Tsis txhob muaj cua los yog hluav taws xob kiv cua, thiab lwm yam.
