Wave soldering zog txuag feem ntau yog hais txog kev siv yoj soldering kom txuag hluav taws xob thiab tin thiab txuag cov khoom siv, yog li siv lub tshuab yoj soldering li cas kom txuag hluav taws xob thiab tin?Yog tias koj tuaj yeem ua cov ntsiab lus hauv qab no, koj tuaj yeem txo qis feem ntau ntawm cov khoom siv tsis tsim nyog, kom cov yoj vuam tuaj yeem ua tiav cov txiaj ntsig txuag hluav taws xob, ntxiv rau kev tu thiab tu txhua hnub ntawm lub tshuab yoj soldering, koj tuaj yeem pib siv lub yoj soldering tshuab.Lub tshuab vuam tuaj yeem tsis tsuas yog ua kom zoo ntawm yoj soldering, tab sis kuj tuaj yeem siv lub hom phiaj txuag hluav taws xob.
1. Txhua tus neeg uas tau siv lub tshuab nthwv dej no paub tias lub zog siv hluav taws xob loj tshaj plaws ntawm yoj soldering feem ntau yog siv hluav taws xob, flux thiab oxidation ntawm tin.Ua ntej tshaj plaws, peb yuav ua li cas thiaj paub siv zog txuag ntau dua.Ua tib zoo saib thaum tig lub tshuab, vim tias cov txheej txheem tin melting ntawm lub cub tawg yuav siv sij hawm 2 teev, yog li thaum lub sij hawm tin melting txheej txheem, thov kaw cov chaw nres tsheb uas xav tau hluav taws xob uas tsis yog lub cub tawg, xws li preheating, tsheb thauj mus los, thiab lwm yam.
2. Lwm thaj chaw uas tuaj yeem txuag hluav taws xob yog khoom siv.Ua ntej, cia saib yuav ua li cas txuag flux.Peb yuav tsum tau kho qhov loj ntawm cov tshuaj tsuag flux raws li qhov loj ntawm PCB.Qhov loj dua cov tshuaj tsuag, qhov loj dua qhov flux ntws, uas yuav ua rau cov khib nyiab tsis tsim nyog thiab cuam tshuam ncaj qha rau cov nyhuv soldering ntawm cov pob qij txha.Peb yuav tsum tau kho nws mus rau lub kaus-zoo li pos huab xeev, uas yuav txo tau cov pov tseg ntawm ntau flux.Lwm cov ntsiab lus yog tias cov flux yuav tsum tau muab kaw kom txo tau cov volatilization ntawm flux.
3. kuj tseem yuav txo tau cov oxidation ntawm tin.Tam sim no qee lub tsev lag luam ntawm kev ua lag luam tau siv cov tin slag txo cov neeg ua haujlwm kom txo qis.Qhov tseeb, qhov no yog txoj hauv kev tsis ncaj ncees lawm, vim tias qhov purity ntawm tin slag txo los ntawm tus neeg sawv cev txo nws yuav txo tau ntau thiab cuam tshuam ncaj qha rau lub neej ntawm cov khoom, yog li peb yuav tsum siv txoj hauv kev kom txuag tau tus nqi ntawm cov tin.
