Dab tsi yog qhov zoo ntawm SMT txhuas-dawb solder muab tshuaj txhuam?

Ua ntej tshaj plaws, cov kev ua phooj ywg ib puag ncig ntawm cov txhuas dawb muab tshuaj txhuam yog ib qho ntawm nws cov txiaj ntsig loj tshaj plaws. Piv nrog cov txhuas cov tshuaj txhuam, txhuas tsis muaj cov tshuaj tiv thaiv txhuas tsis muaj cov tshuaj lom txhuas, yog li nws tsis tso cov txheej txheem ua phom sij thaum cov txheej txheem soldering. Hmoov txhuas yog cov hlau tsis muaj tshuaj lom, thiab ntev ntev lossis nqus cov tshuaj lom txhuas muaj kev kub ntxhov hnyav rau tib neeg kev noj qab haus huv.

Thib ob, txhuas cov solder soldering ua yeeb yam zoo tshaj plaws hauv kev ua kom zoo. Lead-dawb solder muab siv cov khoom zoo tin thiab nyiaj \/ tooj liab alloy raws li cov khoom xyaw tseem ceeb, uas ua rau cov sib koom ua ke nrog lub zog thiab muaj zog txhim khu kev qha.

Ntxiv rau, txhuas tsis muaj ham muab tshuaj txhuam kuj tau qis dua qhov kub. Lead-dawb solder paste yuav tsum tau txo cov kub kub piv rau qhov siab dua melting taw tes ntawm txhuas muab tshuaj txhuam. Qhov yeeb yam no tseem ceeb heev rau solding kub-rawv hluav taws xob kom zam dhau kev puas tsuaj lossis tsis ua haujlwm los ntawm kev kub siab.
