Cov txheej txheem rau soldering hlau
Tom qab ua qhov kev kho mob ua ntej vuam, koj tuaj yeem ua tiav kev vuam.
1, vuam txoj kev.
Soldering Checking Txiav
(1) Tuav cov hlau nplaum ntawm koj sab tes xis. Sab laug tes nrog ntse-nosed pliers lossis tweezers tuav cov khoom lossis cov xov hlau. Ua ntej welding, cov hlau yuav tsum tau preheated tag nrho. Lub ntsis ntawm cov hlau soldering yuav tsum tau noj tin ntawm ntug ntug, uas yog, nrog ib tug npaum li cas ntawm solder.
(2) Muab qhov taub ntawm cov hlau nplaum ruaj khov rau ntawm qhov taw tes. Cov hlau nplaum thiab lub dav hlau kab rov tav ntawm lub kaum sab xis ntawm 60 degree. Txhawm rau pab txhawb qhov ntws ntawm cov tin melted los ntawm qhov kawg ntawm cov hlau mus rau qhov taw tes soldering. Lub sij hawm uas lub taub hau hlau nyob twj ywm ntawm qhov taw tes soldering yog tswj ntawm 2 mus rau 3 vib nas this.
(3) Tshem tawm lub taub hau hlau. Sab laug tes tseem tuav cov khoom. Tos kom txog thaum lub tin ntawm lub solder sib koom ua ke txias thiab solidifies ua ntej tso sab laug tes.
(4) Siv cov tweezers tig cov hlau lead kom paub meej tias nws tsis xoob, thiab tom qab ntawd cov hlau lead ntau dhau tuaj yeem txiav nrog cov pliers offset.
2, vuam zoo
Thaum welding, xyuas kom meej tias txhua qhov taw tes soldering yog khov kho thiab muaj kev sib cuag zoo. Los xyuas kom meej qhov zoo ntawm vuam.
Cov pob qij txha zoo yuav tsum yog lub teeb ci ntsa iab, puag ncig thiab du yam tsis muaj burrs, tus nqi ntawm cov tin yog nruab nrab. Cov tin thiab cov khoom siv soldered yog fused. Yuav tsum tsis muaj qhov cuav soldering thiab cuav soldering.
False soldering tsuas yog ib qho me me ntawm cov tin soldered ntawm qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo, qee zaum los ntawm qee zaum tawm. False soldering yog qhov saum npoo zoo li yuav tsum tau soldered, tab sis qhov tseeb tsis yog soldered, qee zaum nrog ib txhais tes rub, cov hlau lead tuaj yeem rub tawm ntawm qhov sib koom ua ke. Ob qhov xwm txheej no yuav ua rau muaj teeb meem loj rau kev debugging thiab overhauling ntawm cov khoom siv hluav taws xob. Ob qhov xwm txheej no tsuas yog zam tau nrog kev ua haujlwm ceev faj ntau.
Thaum soldering circuit boards, nco ntsoov tswj lub sijhawm. Ntev dhau lawm thiab lub rooj tsav xwm Circuit Court yuav raug hlawv lossis ua rau cov ntawv ci tooj liab poob. Thaum tshem cov khoom los ntawm lub rooj tsav xwm hauv Circuit Court, lo lub hau ntawm cov hlau soldering rau ntawm cov khoom sib txuas thiab rub tawm cov khoom tom qab cov tin ntawm cov khoom sib txuas tau yaj.
Soldering flux (rosin thiab soldering roj) yog qhov tseem ceeb, rosin tshiab thiab cov roj uas tsis muaj corrosive tuaj yeem pab koj ua kom tiav cov soldering zoo heev, thiab tuaj yeem ua kom lub ntsej muag huv si thiab zoo nkauj, koj tuaj yeem siv ntau flux!
