Taw qhia txog kev xaiv hluav taws xob soldering hlau
Kev xaiv lub zog ntawm 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.
2. Kev xaiv hluav taws xob soldering hlau fais fab
(1) Thaum welding low-power resistive thiab capacitive Cheebtsam, transistors, integrated circuits, luam Circuit Court boards, pads los yog yas xov hlau, nws yog advisable siv 30-45W externally rhuab los yog 20W sab hauv rhuab soldering hlau. Qhov kev xaiv zoo tshaj plaws rau daim ntawv thov yog siv 20W sab hauv cua sov hluav taws xob soldering hlau.
(2) Thaum vuam cov ntsiab lus ntawm cov khoom siv dav dav, xws li cov hlua hlau, hlau claws, cov cua sov dissipation fins, cov ntaub qhwv hauv av, thiab lwm yam, nws raug nquahu kom siv 75-100W hluav taws xob soldering hlau.
(3) Rau cov ntsiab lus vuam loj, xws li cov kab hlau txuas txuas, vuam pads, thiab lwm yam, nws raug nquahu kom siv 100-200W hluav taws xob soldering hlau.
