Yuav ua li cas los txiav txim qhov hluav taws xob soldering hlau tsis kam
Hluav taws xob soldering hlau yog cov cuab yeej tseem ceeb rau kev tsim hluav taws xob thiab kev saib xyuas hluav taws xob. Nws lub hom phiaj tseem ceeb yog weld Cheebtsam thiab cov xov hlau. Raws li tus neeg kho tshuab qauv, nws tuaj yeem muab faib ua hom hluav taws xob sab hauv hluav taws xob thiab sab nraud hom hluav taws xob hluav taws xob. Tin-type soldering irons yog muab faib ua high-power soldering irons thiab low-power soldering irons raws li kev siv sib txawv.
Qhov kev ntsuam xyuas hlau soldering muaj peb ntu: kev sim hauv av (lub xeev txias / kub), qhov ntsuas hluav taws xob to thiab qhov ntsuas tam sim no.
1. Grounding resistance test ntawm hluav taws xob soldering hlau hauv lub xeev txias:
Nyob rau hauv cov ntaub ntawv uas tsis muaj hluav taws xob, txuas ib kawg ntawm lub multimeter cwj mem mus rau hauv av kawg ntawm lub hwj chim plug, thiab lwm yam kawg mus rau lub ntsis ntawm cov hluav taws xob soldering hlau los ntsuam xyuas cov ntaub ntawv;
2. Grounding resistance test ntawm hluav taws xob soldering hlau nyob rau hauv lub xeev cua sov:
Txuas lub fais fab mov, tig rau hluav taws xob soldering hlau, kov ib kawg ntawm lub multimeter cwj mem mus rau hauv av davhlau ya nyob twg ntawm lub hwj chim sawb, thiab lwm yam kawg rau lub xeem board nyob rau hauv kev sib cuag nrog hluav taws xob soldering hlau, thiab ntsuas qhov tshwm sim;
3. Kev ntsuas hluav taws xob xau thiab qhov ntsuas tam sim no ntawm cov hluav taws xob soldering hlau zoo ib yam li cov qauv ntsuas kev tiv thaiv. Nws yuav tsum tau muab sau tseg tias txoj hauj lwm ntawm multimeter cwj mem kab yuav tsum tau kho thaum lub multimeter yuav tsum tau hloov lub zog los yog ntsuas qhov tam sim no.
Ntev npaum li cas cov hlau soldering kub
Lub zog ntawm 60w soldering hlau yog siab heev, tab sis feem ntau cov hlau soldering yuav tsum tau preheated rau 3-5 feeb. Txawm hais tias koj yuav pom nws tau kub thiab haus luam yeeb, nws yuav tsis tau mus txog qhov melting point ntawm solder. Lub sij hawm sov so ntawm cov hlau soldering kuj muaj feem xyuam rau kev siv ib puag ncig. Lub sij hawm sov so yuav ntev dua nyob rau hauv ib qho chaw uas muaj cua kub thiab tsis kub. Nws raug nquahu kom siv qee qhov kev tiv thaiv rau cov hlau soldering (xws li ntxiv lub tes tsho) kom ntseeg tau tias cov hlau tuaj yeem kav ntev. Sau cov cua sov kom ncav cuag qhov kub thiab txias.
Lub tshuab hluav taws xob tshiab yuav muaj cov pa luam yeeb me ntsis thiab tsw ntxhiab tsw thaum siv thawj zaug. Muaj ib txheej ntawm cov tshuaj tiv thaiv oxidation ntawm cov hlau soldering, uas yuav tsum tau muab tshem tawm maj mam ua ntej siv. Rau thawj zaug siv, lub solder yuav tsum tau tag nrho pub rau lub ntsis ntawm lub soldering hlau, thiaj li hais tias nws muaj peev xwm nqus tag nrho cov tin thiab ces solder.
