Tam sim no uas siv tag nrho cov hlau lead-dawb soldering, lub Hoobkas-muas hluav taws xob soldering irons (cov chaw nres tsheb) tsis tuaj yeem yuav nrog cov ntsiab lus ib txwm muaj. Cov hluav taws xob tswj hluav taws xob zoo tib yam hauv kev lag luam, txawm hais tias muaj peev xwm raug teeb tsa rau 400 degrees lossis siab dua, qhov tseeb, lawv lub peev xwm kub thiab kub rov qab muaj peev xwm tsis txaus los tuav cov hlau lead-dawb kub kub hauv lub rooj plaub ntawm cooler solder pob qij txha. Thaum lub sij hawm soldering, txhuas-dawb tin hlau nrog lub melting point siab tshaj li ntawm 34 degree muaj ib tug kuj loj tshav kub dissipation peev. Yog tias qhov chaw tswj qhov kub thiab txias zoo tib yam siv los ua kom tsis muaj qhov kub thiab txias (tshwj xeeb tshaj yog thaum lub vuam sib koom ua ke loj) Nws yuav ua rau tin burrs, virtual soldering thiab qeeb heev soldering ceev vim tsis txaus tshav kub zog; Yog li ntawd, txhawm rau ua tiav cov txiaj ntsig tsim nyog, nws yog ib qho tsim nyog yuav tsum tau nce qhov kub ntawm soldering hlau raws li, tab sis nce qhov kub ntawm qhov kub yuav ua rau muaj ntau yam tsis zoo. ,
A. Cov hlau tsis muaj hlau lead yog yooj yim oxidized dua li cov hlau lead, thiab qhov kub siab ua lub luag haujlwm catalytic, thiab oxidation tus nqi nce exponentially nrog qhov kub thiab txias, yog li vuam ntawm qhov kub tsis tshua muaj siab heev yuav ua rau cov neeg kho tshuab hu virtual vuam. (Lub solder tsis tsim ib qho intermetallic molten alloy txheej ntawm lub workpieces yuav tsum tau welded) thiab solder pob qij txha yog grey thiab dawb;
B. Lub xeev zoo tshaj plaws ntawm cov hlau soldering tsis yog kom tawm hauv qhov kub thiab txias, kom tshem tawm lub zog cia, thiab tam sim ntawd ntxiv lub zog uas tau txais los ntawm lub zog hluav taws xob mus rau qhov chaw vuam, uas tuaj yeem tsis tsuas yog zam kev poob ntawm lub zog. Qhov loj tshaj plaws tab sis kuj ua tau zoo vuam, tab sis Ordinary soldering irons tsis tuaj yeem ua tiav vim qhov cua sov qeeb, thiab tsuas yog khaws cov cua sov kom txaus kom ncav cuag qhov kub thiab txias uas yuav tsum tau ua los ntawm cov khoom siv los ntawm kev ua kom sov, thiab qhov kub siab dua yuav ua rau thermal shock zoo rau cov khoom me me. , kom qhov kev ua tau zoo ntawm Circuit Court thiab kev ua haujlwm ntawm tag nrho lub tshuab raug cuam tshuam ncaj qha lossis tsis ncaj qha.
C. Feem ntau cov chaw tsim khoom hluav taws xob, tshwj xeeb tshaj yog cov khoom lag luam optoelectronic yuav muaj kev tswj xyuas nruj ntawm qhov chaw ntawm vuam kub. Qhov qis dua qhov kub thiab txias, qhov zoo dua yog tias nws tuaj yeem ua tau raws li cov txheej txheem vuam. Yog li ntawd, qhov kub siab dua vuam tsis tuaj yeem ua tau raws li cov txheej txheem vuam tsim los ntawm lub Hoobkas. Xav tau.
Txhawm rau yuav qhov chaw nres tsheb tsis muaj hlau lead (soldering hlau), koj yuav tsum xub xyuas ob lub ntsiab lus:
1. Xyuas kom meej tias qhov kub ntawm qhov soldering yog li 350 degree
2. Xyuas kom meej tias qhov vuam ceev yog 3-4 vib nas this rau ib qho kev sib koom ua ke
Lub peev xwm los lav rau ob lub ntsiab lus saum toj no yog hu ua chaw nres tsheb tsis muaj hlau lead. Yog tias nws tsis pom zoo kom nce qhov kub thiab txias kom ua tau raws li qhov kev lees paub ntawm kev sib tw ceev, nws yuav cuam tshuam rau qhov zoo ntawm cov pob qij txha thiab ua rau lub neej ua haujlwm luv ntawm lub taub hau.
Cov chaw nres tsheb tsis muaj txhuas (soldering hlau) feem ntau muaj ntau lub zog ntawm 80W, 100W, 120W, thiab 150W. Qhov chaw nres tsheb tsis muaj hlau lead (soldering hlau) ntawm 80W rau feem ntau cov pob qij txha tuaj yeem txaus siab. Yog tias cov pob qij txha loj dhau lawm, qhov chaw nres tsheb tsis muaj cov hlau lead (soldering hlau) uas muaj zog dua tuaj yeem xaiv.
