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 xav tau rau qhov ntsuas kub kom rov qab mus rau qhov kub siab tshaj plaws tom qab nws tau poob 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.
2. Lub hauv paus ntsiab lus ntawm lub zog rau kev xaiv cov hlau soldering yog raws li hauv qab no:
① Thaum soldering integrated circuits, transistors thiab lwm yam khoom uas raug 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 tshaj 100W.
Yuav ua li cas desolder
Desoldering yog yuav tsum tau thaum lub sij hawm debugging thiab txij nkawm, los yog thaum lub Cheebtsam raug hloov vim welding yuam kev. Txoj kev desoldering tsis raug feem ntau ua rau cov khoom puas tsuaj, tawg ntawm cov xov hlau luam tawm, lossis kev tshem tawm ntawm cov ntaub qhwv. Kev siv thev naus laus zis zoo tuaj yeem ua kom ntseeg tau qhov kev ua tiav ntawm kev debugging thiab tu ua haujlwm thiab zam kom tsis txhob nce cov khoom lag luam vim qhov hloov tsis raug ntawm cov khoom.
Desoldering ntawm common Cheebtsam:
1) Xaiv ib qho kev kho mob hollow koob rau desoldering
2) Desoldering nrog tooj liab braided hlau
3) Siv lub hnab ntim cua tshuab rau cov khoom siv kom tshem tawm
4) Siv ib qho tshwj xeeb desoldering hlau rau desolder
5) Siv cov hlau soldering rau desolder.
