Vim li cas 380 degree soldering hlau taub tsis tinned?
Nws yog kiag li tsis yooj yim sua rau lub ntsis ntawm 380 degree soldering hlau tsis txhob tinned.
Tom qab ntawd vim li cas qee cov neeg siv khoom tau tshaj tawm tias lub hau ntawm cov hlau tsis yog tinned thaum ua cov hlau lead-dawb soldering ntawm 380 degree? Ua ntej tshaj plaws, 380 degree yog ntsuas hauv lub xeev zoo li qub, tab sis qhov tseeb tsis muaj qhov kub thiab txias thaum lub sijhawm vuam.
Cia peb saib qhov kev sib raug zoo ntawm qhov kub thiab txias ntawm soldering nyob rau hauv cov ntaub ntawv ntawm txhuas thiab lead-free soldering:
Hom vuam hlau Melting point Vuam kub Vuam ceev
6337 vuam hlau 183 degree 350 degree txog 4 vib nas this / daim
Lead-free solder hlau 220 degree 390 degree Txog 6 vib nas this / daim
Peb qhov kev sib tw ib txwm yog 3-4 vib nas this ntawm qhov taw tes, tab sis nws yog li 6 vib nas this ntawm qhov taw tes thaum peb ua cov hlau tsis muaj hlau lead ntawm 390 degree, thiab qhov chaw nres tsheb yuav tsum tau siv sijhawm ntev dua. Cov chaw nres tsheb sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias, qhov nrawm dua qhov zoo dua, cov chaw siv hluav taws xob muaj peev xwm them nyiaj tsis zoo, thiab qhov kub tsis ncav cuag lub sijhawm vuam. Yog li ntawd, qee cov neeg siv khoom tau tshaj tawm tias qhov ntxeev ntawm cov hlau tsis yog tinned thaum ua cov hlau lead-dawb soldering ntawm 380 degree.
