Vim li cas lub taub hau hlau tsis muaj 380 degree tin txheej?
Nws yog tsis yooj yim sua kom solder lub taub hau ntawm 380 degree yam tsis muaj tin.
Yog li vim li cas qee cov neeg siv khoom tau tshaj tawm tias cov taub hau hlau tsis tuaj yeem tinned thaum siv 936 soldering chaw nres tsheb rau cov hlau lead-free soldering ntawm 380 degree? Ua ntej ntawm tag nrho cov, qhov no 380 degree tau ntsuas nyob rau hauv ib tug zoo li qub, tab sis qhov tseeb kub tsis zoo li thaum lub sij hawm vuam. Cia kuv siv qhov chaw nres tsheb HAKKO936 ua piv txwv thiab txhua tus yuav nkag siab.
Ua ib qho piv txwv ntawm HAKKO936 soldering chaw nres tsheb, cia saib qhov kev sib raug zoo ntawm qhov kub thiab txias thiab vuam ceev hauv cov hlau lead thiab tsis muaj hlau lead:
Vuam hlau hom melting point vuam kub vuam ceev
6337 vuam hlau 183 degree 350 degree txog 4 vib nas this / daim
Lead-free soldering hlau 220 degree 390 degree Txog 6 vib nas this / daim
Peb qhov vuam ceev li ib txwm yog 3-4 vib nas this ntawm qhov taw tes, thaum lub HAKKO936 soldering chaw nres tsheb ua cov hlau lead-dawb soldering ntawm 390 degree rau li 6 vib nas this ib qhov taw tes soldering, thiab lub tsev 936 soldering chaw nres tsheb yuav siv sij hawm ntev dua. Cov chaw sib txawv soldering muaj qhov sib txawv ntawm qhov kub thiab txias. Qhov nrawm dua qhov zoo. Lub tsev 936 soldering chaw nres tsheb muaj peev xwm them nyiaj tsis zoo thiab qhov kub tsis tau mus txog thaum vuam ib txwm. Yog li ntawd, qee cov neeg siv khoom tau tshaj tawm tias cov hlau nplaum tsis tau tinned thaum siv 936 soldering chaw nres tsheb rau cov hlau lead-free soldering ntawm 380 degree.
Kev ntsuas kub ntawm cov lus qhia tsis muaj hlau lead
Qhov kub ntawm phau ntawv siv lead-free soldering yog qhov tseem ceeb heev. Nws yog qhov taw qhia tseem ceeb uas cuam tshuam rau lub neej kev pab cuam ntawm cov hlau lead-dawb soldering taub hau, thiab tseem yog ib qho tseem ceeb qhia uas cuam tshuam rau qhov zoo ntawm cov pob qij txha. Yog li ntawd, kev ntsuas qhov kub ntawm cov hlau taub hau yog qhov tseem ceeb heev.
Yog li yuav ua li cas ntsuas qhov kub ntawm cov hlau taub hau?
1. Ua ntej ntawm tag nrho cov, yuav ib tug zoo soldering ntsis kub tester.
2. Siv txoj kev ntsuas kom raug. Thaum lub sij hawm ib txwm siv cov hluav taws xob soldering hlau (soldering chaw nres tsheb), ntxiv tin mus rau lub ntsis ntawm lub soldering hlau thiab ncaj qha mus cuag nws nyob rau hauv nruab nrab ntawm lub kub ntsuas kab ntawm lub ntsuas kub ntsuas. Qhov siab tshaj qhov ntsuas kub tsis tu ncua yog qhov ntsuas kub tiag tiag. Thaum ntsuas, ntau tus engineers siv lub tin hlau los ntsuas cov khoom siv soldering. Tom qab cov tin melts, lub taub hau hlau soldering sai tawm qhov ntsuas kub ntawm qhov taw tes, yog li ntsuas qhov ntsuas kub yog qhov kub tshaj plaws thaum lub sij hawm soldering. (Qhov ntsuas kub no yog kaum kaum degrees sib txawv ntawm qhov ntsuas kub los ntawm qhov qub) Qhov tseem ceeb ntawm qhov zoo ntawm cov hlau tsis muaj hlau lead (soldering chaw nres tsheb) qhia tau tias qhov sib txawv ntawm ob qhov kub yuav tsum yog me me. Qhov thib ob yog tias qhov nrawm dua nws mus los ntawm qhov ntsuas kub qis tshaj mus rau qhov kub siab tshaj plaws, qhov zoo dua. , uas yog qhov peb hu ua kev rov qab sai.
3. Qhov zoo tshaj plaws kub ntawm 350 degree rau cov hlau lead-free soldering uas peb feem ntau hu yog ntsuas los ntawm thawj txoj kev, tsis yog qhov thib ob.
