Cov hauv paus ntsiab lus hauv qab no feem ntau ua raws li kev xaiv cov hlau soldering:
① Cov duab ntawm cov hlau taub hau yuav tsum tau ua raws li qhov yuav tsum tau ua ntawm qhov chaw ntawm cov khoom siv thiab qhov ntom ntawm cov khoom sib dhos.
② Lub taub hau kub ntawm lub taub hau hlau yuav tsum sib haum nrog lub melting point ntawm lub solder, feem ntau siab tshaj qhov melting point ntawm solder 30 - 80 degree (tsis suav qhov kub ntawm lub taub hau soldering hlau nyob rau hauv kev sib cuag nrog lub soldering point. ntawm qhov kub poob).
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 lub taub hau hlau yuav tsum tau yoog raws li qhov yuav tsum tau ua ntawm cov khoom siv soldered nto. Lub sij hawm rov qab los ntawm qhov kub thiab txias yog txhais raws li lub voj voog vuam, lub taub hau ntawm lub taub hau ntawm lub taub hau ntawm qhov kub thiab txias vim yog cua sov dissipation thiab txo, thiab tom qab ntawd rov qab mus rau * lub sij hawm kub siab xav tau. Nws muaj feem xyuam rau lub zog hlau soldering, lub peev xwm ntawm cov cua sov thiab cov duab thiab qhov ntev ntawm lub taub hau hlau.
Xaiv lub hwj chim ntawm cov ntsiab lus hlau soldering yog raws li hauv qab no:
① vuam integrated circuits, transistors thiab lwm yam kub-rhiab heev Cheebtsam, xav txog kev xaiv ntawm 20W endothermic los yog 25W sab nraud tshav kub soldering hlau.
② Vuam thicker xov hlau thiab coaxial cable, xav txog kev xaiv ntawm 50W endothermic los yog 45 - 75W sab nraud kub soldering hlau.
③ Soldering loj Cheebtsam, xws li hlau chassis grounding pads, yuav tsum xaiv ntau tshaj 100W soldering hlau.
Kev siv hlau soldering
soldering hlau yuav tsum tsis txhob energized rau ib ntev lub sij hawm tsis siv, qhov no yuav ua rau cov tub ntxhais ntawm cov hlau soldering kom ceev cov oxidation thiab hlawv tawm, shorten nws lub neej, tab sis kuj yuav ua rau lub taub hau ntawm lub soldering hlau vim cua sov ntev. thiab oxidation, thiab txawm yuav "kub" tsis tau "noj tin".
Nco ntsoov siv cov hlau soldering
① raws li cov khoom siv vuam tsim nyog xaiv ntawm ntau hom hlau soldering.
② Tsis txhob arbitrarily ntaus lub taub hau ntawm soldering hlau nyob rau hauv tus txheej txheem ntawm kev siv kom tsis txhob muaj kev puas tsuaj. Endothermic soldering hlau txuas pas nrig steel phab ntsa tuab ntawm tsuas yog 0.2 hli, tsis tuaj yeem clamped nrog pliers kom tsis txhob muaj kev puas tsuaj. Nyob rau hauv tus txheej txheem ntawm kev siv yuav tsum tsis tu ncua kom ntseeg tau tias lub taub hau soldering hlau hangs ib tug nyias txheej ntawm tin.
