Xaiv qhov zoo tshaj plaws Circuit board board solderis tus txheej txheem uas tuaj yeem siv tes ua ob peb yam sib txawv. Qhov kev xav tseem ceeb tshaj yog hom soldering uas koj tau ua, txij li cov tswv yim sib txawv hu rau hom tshwj xeeb ntawm solder. Piv txwv li, reflow los yog yoj soldering feem ntau yuav tsum muaj cov khoom sib txawv uas soldering nrog cov tub rog hlau. Muaj, txawm li cas los xij, qee qhov alloys uas tau pom zoo rau ob qho kev siv.
Thaum nrhiav rau qhov zoo tshaj plaws Circuit Court cam ham, thawj qhov kev txiav txim siab koj yuav tsum tau ua yog dab tsi ntawm soldering koj npaj yuav ua. Yog hais tias koj yog reflow los yog yoj soldering, koj yuav tsum tau saib rau lub rooj tsav xwm Circuit Court cam uas tsis muaj flux. Qhov no yog vim qhov tseeb tias flux feem ntau tau thov los ntawm nws tus kheej ua ntej daim ntawv thov ntawm ham. Yoj thiab reflow soldering yog tseem ua nrog cam muab tshuaj, thiab lub sijhawm ua cov hmoov txhuas tuaj yeem qee zaum ua rau cov hlau tsim ua npuas, nrog rau muaj kev txhawj xeeb txog ib puag ncig.
Muag nrog hlau yog qhov yooj yim dua yog tias koj xaiv cov khoom lag luam uas muaj rosin-core. Ua ke ntawm flux sab hauv lub qhov cub ua kom yooj yim dua, uas tuaj yeem pab txoj haujlwm mus nrawm dua. Lwm qhov tseem ceeb los xav txog yog cov alloy cov nyiaj ua tau los ntawm, txawm hais tias ib qho alloy ntawm tin thiab txhuas uas muaj ntau dua 60% tin feem ntau zoo txaus rau hluav taws xob ua haujlwm.
Tom qab koj tau txiav txim siab seb koj puas xav tau cov khoom lag luam tawv lossis muab tshuaj txhuam Circuit board cam, koj yuav tsum siv ntau lub ntsiab lus ntxiv rau hauv kev txiav txim siab. Txawm hais tias txoj cai dav dav yog xaiv cov ham uas muaj ntau dua 60% tin, qee cov ntawv thov hu rau cov alloys tshwj xeeb. Yog tias koj tabtom ua haujlwm nrog lub rooj tsav xwm hauv Circuit Court uas cov solder yuav los rau hauv kev sib txuas nrog kub lossis nyiaj lub cev hluav taws xob kab lossis cov khoom siv, koj yuav tsum xaiv cov tshuaj txhuam uas tsis xeb tawm nrog cov hlau.
Lub xub ntiag ntawm tin nyob rau hauv solder yuav ua tau yaj ob qho tib si kub thiab nyiaj. Circuit board solder uas muaj indium yog ib qho kev xaiv zoo yog tias nws yuav nkag rau kub, vim tias indium tsis hnov mob kub nrog txoj kev uas tin ua. Ntxiv cov nyiaj rau qhov sib xyaw ntawm tin thiab txhuas tuaj yeem pab txo qis kev cuam tshuam rau cov nyiaj pawg thawj coj saib hauv pawg thawj coj, txawm hais tias cov hlau tsis muaj txhuas yuav siv rau hauv cov teeb meem no ib yam.
