Kev xaiv lub zog rau soldering hlau
Kev siv lub zog ntawm cov hlau nplaum loj heev, nws yog ib qho yooj yim rau hlawv cov khoom (feem ntau diode, triode node kub tshaj 200 degree yuav hlawv) thiab ua rau cov ntawv luam tawm ntawm lub substrate; Kev siv lub zog ntawm cov hlau nplaum me me dhau lawm, cov khoom siv tsis tuaj yeem yaj tag nrho, cov flux tsis tuaj yeem hloov pauv, cov pob qij txha tsis du, tsis ruaj khov, yooj yim los tsim virtual vuam. Feem ntau, siv rau vuam integrated circuits, printed circuit boards, CMOS circuits, hniav transistors, IC-type tape recorders, TVs, rau kev sim Circuit Court, feem ntau 20W yog tsim nyog, kho lub tshuab nqus tsev raj, xws li lub gallbladder, cov cuab yeej qub, rau 35W yog qhov tsim nyog, hom hluav taws xob sab nraud yog 45W, vuam loj hloov hluav taws xob thaiv, cov khoom siv hauv av ntawm cov hlau substrate, nws yog kev siv cov cua sov sab hauv 50W, sab nraud cua sov hom 75W, muaj qee zaus muaj zog dua.
Muaj ntau hom duab ntawm lub taub hau hlau, lub ntsiab lus ntawm kev xaiv yog feem ntau muaj peev xwm tuav tau qee yam ntawm cov solder, tuaj yeem ua kom sai thiab zoo yaj lub solder ntawm lub connector, tsis tsim cov khoom cuav, hitching, dai tin, soldering pob qij txha tsis muaj burrs, tsis txhob hlawv lub rooj tsavxwm thiab cov khoom. Lub tshuab ntawm qhov taw tes ntawm lub qhov ncauj tshiab ci ntsa iab, tom qab ntawd lub taub hau ntawm lub taub hau dipped nyob rau hauv tin cross-section tuaj yeem loj dua, nrog lub taub hau tiaj tus lossis oval, ceev ceev hloov pauv lub ntuj ua haujlwm. Thick oxidized txheej ntawm tin nto, lub taub hau hlau yog qhov taw qhia ntau dua, yooj yim rau kev tawg.
Cheebtsam uas muaj qhov ntom ntom ntom ntom ntom ntom, yuav tsum tau siv lub taub hau nyias nyias ferrous alloy kom tsis txhob hlawv thiab tin. Kev txhim kho thiab disassembly ntawm IC blocks, feem ntau siv cov duab tshwj xeeb ntawm cov hlau taub hau. Qee lub sij hawm vim yog vuam, thiab kom tsis txhob scalding cov khoom yas, kev xaiv ntawm lub taub hau hlau nkhaus. Tau kawg, nws kuj nyob ntawm tus cwj pwm kev ua haujlwm thiab kev nyiam ntawm txhua tus neeg.
Raws li kev xaiv ntawm lub zog ntawm cov hlau soldering
(1) welding me me zog resistive Cheebtsam, transistors, integrated circuits, luam Circuit Court boards los yog yas xov hlau, nws yog tsim nyog los siv 30 ~ 45W sab nraud tshav kub los yog 20W endothermic soldering hlau. Daim ntawv thov ntawm 20W endothermic soldering hlau yog qhov zoo tshaj plaws.
(2) vuam cov qauv ntawm cov khoom vuam taw tes, xws li lub nplhaib hlau, hlau claw, lub dab dej kub, cov ntaub qhwv hauv av, thiab lwm yam, yuav tsum tau siv 7 5 ~ 100W soldering hlau. (3) Rau cov ntsiab lus vuam loj, xws li vuam hlau ncej pob qij txha, vuam daim, thiab lwm yam, nws tsim nyog siv 100 ~ 200W soldering hlau.
