Soldering hlau vuam ua hauj lwm posture thiab tu cev
Cov tshuaj volatilized los ntawm cua sov flux yog teeb meem rau tib neeg lub cev. Yog tias lub qhov ntswg nyob ze rau qhov kawg ntawm cov hlau soldering thaum lub sijhawm ua haujlwm, nws yooj yim rau nqus tau cov pa phem. Feem ntau, qhov kev ncua deb ntawm cov hlau mus rau lub qhov ntswg yuav tsum yog tsawg kawg yog tsis tsawg tshaj li 30cm, feem ntau 40cm yog tsim nyog.
Muaj peb txoj hauv kev los tuav cov hluav taws xob soldering hlau, raws li qhia hauv daim duab 1. Txoj kev tiv thaiv kev tuav yog ruaj khov hauv kev ua haujlwm, thiab nws tsis haum rau kev qaug zog tom qab ua haujlwm ntev. Nws yog qhov tsim nyog rau kev ua haujlwm ntawm high-power soldering hlau. Lub overhand tuav yog tsim rau kev khiav hauj lwm nrog nruab nrab-lub zog soldering hlau los yog hlau nrog lub kaum sab xis. Feem ntau, thaum vuam luam tawm Circuit Board thiab lwm yam weldments ntawm lub rooj ua haujlwm, tus cwj mem tuav yog feem ntau siv.
Taw qhia txog yuav ua li cas solder SMD Cheebtsam
SMD Cheebtsam yog qhov nyuaj heev rau soldering nrog cov hlau soldering raws li cov khoom siv zoo tib yam vim lawv qhov me me. Es tsis txhob, tshwj xeeb solder muab tshuaj txhuam yog yuav tsum tau rau soldering. Welding SMD Cheebtsam nyob rau hauv cov kev ua ub ua no tuaj yeem mus rau tom khw los yuav SMD solder paste. Tam sim no muaj ob hom kev lag luam, ib qho yog solder paste uas tau hloov kho, lub cim lag luam yog Vajtswv Vuam, thiab lwm yam yog ua los ntawm cov tshuaj txhuam thiab muab tshuaj txhuam cov tshuaj txhuam los ntawm kev sib xyaw tus neeg sawv cev, cov cim lag luam yog qhov muag loj. hom.
Txoj kev vuam yog: muab cov khoom SMD tso rau ntawm lub ncoo, thiab tom qab ntawd siv qhov hloov kho SMD solder paste rau ntawm kev sib cuag ntawm tus pin thiab lub ncoo (ceev faj tsis txhob siv ntau dhau los tiv thaiv luv luv), thiab tom qab ntawd siv 20W sab hauv. Thaum tshav kub kub Siv hom hluav taws xob soldering hlau los ua kom sov qhov kev sib txuas ntawm lub ncoo thiab SMD tivthaiv (qhov kub yuav tsum yog 220 ~ 230 degree), thiab koj tuaj yeem tshem tawm cov hluav taws xob soldering hlau tom qab lub solder yog yaj, thiab cov soldering tiav tom qab lub soldering hlau. solder solidifies. Tom qab vuam, koj tuaj yeem siv cov tweezers los tuav cov khoom siv SMD los xyuas seb puas muaj qhov xoob. Yog tias tsis muaj qhov xoob (yuav tsum muaj zog heev), nws txhais tau tias qhov vuam zoo. Yog tias muaj qhov xoob, koj yuav tsum rov ua dua qee qhov SMD solder paste thiab solder raws li cov txheej txheem saum toj no.
