Cov lus qhia rau kev txiav txim siab lub zog ntawm cov hlau
Feem ntau ua raws li cov hauv qab no thaum xaiv cov hlau soldering:
① Cov duab ntawm lub taub hau hlau yuav tsum hloov mus rau qhov yuav tsum tau ua ntawm qhov chaw yuav tsum tau welded thiab cov khoom sib dhos ntom ntom.
② Qhov kub ntawm lub taub hau ntawm lub taub hau yuav tsum tau sib haum nrog lub melting point ntawm lub solder, uas yog feem ntau yog 30-80 degree siab tshaj qhov melting point ntawm lub solder (tsis suav qhov kub poob thaum lub soldering hlau taub hau. 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 lub taub hau hlau yuav tsum tau yoog raws li qhov yuav tsum tau ua ntawm qhov chaw ntawm qhov welded. Lub sijhawm ntsuas kub rov qab yog hais txog lub sijhawm uas yuav tsum tau ua rau qhov ntsuas kub ntawm lub taub hau kom rov qab mus rau qhov kub siab tshaj plaws tom qab nws txo qis vim qhov kub poob thaum lub voj voog vuam. Nws muaj feem xyuam rau lub hwj chim thiab kub muaj peev xwm ntawm cov hluav taws xob soldering hlau thiab cov duab thiab ntev ntawm lub taub hau soldering hlau.
Lub zog lub hauv paus ntsiab lus rau xaiv ib tug soldering hlau yog raws li nram no:
① Thaum soldering integrated circuits, transistors thiab lwm yam khoom uas yooj yim puas los ntawm tshav kub, xav txog siv 20W sab hauv cua sov los yog 25W sab nraud cua sov soldering hlau.
② Thaum welding thicker xov hlau thiab coaxial cables, xav txog siv 50W cua sov sab hauv los yog 45-75W sab nraud cua sov soldering hlau.
③ Thaum vuam cov khoom loj dua, xws li hlau chassis grounding lug, koj yuav tsum xaiv cov hlau uas muaj zog ntawm 100W lossis siab dua.
Kev siv cov hlau soldering
Cov hluav taws xob soldering hlau yuav tsum tsis txhob siv rau lub sijhawm ntev yam tsis tau siv. Qhov no yuav yooj yim ua rau cov tub ntxhais hlau soldering kom nrawm oxidation thiab hlawv tawm, ua rau nws lub neej luv. Nyob rau tib lub sijhawm, lub taub hau hlau yuav raug oxidized vim cua sov mus ntev, thiab tej zaum yuav "hluav taws" thiab tsis "noj" tin lawm. .
Kev ceev faj rau kev siv hlau soldering
① Xaiv cov khoom sib txawv ntawm cov hlau vuam kom tsim nyog raws li cov khoom siv vuam.
② Tsis txhob ntaus lub taub hau ntawm cov hlau arbitrarily thaum siv kom tsis txhob muaj kev puas tsuaj. Cov phab ntsa tuab ntawm cov yeeb nkab steel ntawm cov cua sov sab hauv cov hlau txuas txuas tsuas yog 0.2 hli, yog li nws tsis tuaj yeem clamped nrog pliers kom tsis txhob muaj kev puas tsuaj. Nws yuav tsum tau khaws cia tsis tu ncua thaum siv los xyuas kom meej tias cov hlau taub hau yog npog nrog ib txheej nyias ntawm tin.
