Ua rau Thiab Kev daws teeb meem ntawm Cov Tin Tsis Zoo Rau Cov Kub Kub Kub Kub PCB

Lub Immersion kub PCB tam sim no yog hom khoom siv dav tshaj plaws, nws tuaj yeem siv tsis tau tsuas yog hauv kev tsim kho, tab sis kuj tseem nyob rau hauv kev tsim cov khoom pib, cov khoom siv hluav taws xob thiab lwm yam. Hauv kev lag luam tsim hluav taws xob, tinning ntawm Immersion kub PCB yog txheej txheem tseem ceeb heev. Tin ntawm Immersion kub PCB tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob, thiab ua kom muaj kev ntseeg siab thiab ruaj khov ntawm cov khoom siv hluav taws xob. Txawm li cas los xij, qee zaum yuav muaj qhov tshwm sim tsis zoo nyob rau hauv cov txheej txheem ntawm tinning Immersion kub PCB, nws yuav ua rau qhov zoo ntawm cov khoom siv hluav taws xob tsim los ua tsis tau raws li tus qauv. Yog li, dab tsi yog vim li cas thiab kev daws teeb meem rau qhov phem tin ntawm Immersion kub PCB?

vim li cas

Tsis tu kom zoo: Kev tu kom zoo yog tus yuam sij rau tinning ntawm Immersion kub PCB. Yog tias nws tsis tau ntxuav kom huv si, cov roj thiab cov impurities nyob rau saum npoo ntawm Immersion kub PCB yuav cuam tshuam cov adsorption thiab diffusion ntawm tin, uas ua rau cov tin txheej tsis sib xws.

Hlau oxidation: Cov hlau oxidation nyob rau saum npoo ntawm Immersion kub PCB yuav cuam tshuam rau adsorption thiab diffusion ntawm tin. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua raws li kev kho kom txo qis ntawm Immersion kub PCB.

Qhov kub tsis sib xws: qhov kub tsis sib xws yuav ua rau qhov tsis sib xws ntawm cov tin, nws yuav cuam tshuam rau qhov zoo ntawm tin ntawm Immersion kub PCB.

Qhov zoo ntawm cov khoom tin tsis zoo: yog tias qhov zoo ntawm cov khoom tin tsis zoo, cov nyhuv ntawm cov tin ntawm Immersion kub PCB yuav tsis zoo.

Kev daws

Kev tu kom huv, xaiv tus neeg saib xyuas thiab kev tu kom zoo, ntxuav cov roj thiab cov impurities ntawm qhov chaw ntawm Immersion kub PCB, kom ntseeg tau tias qhov chaw ntawm Immersion kub PCB yog huv si thiab tsis muaj impurities.

Ua raws li kev kho kom txo tau qhov tsim nyog: tus neeg sawv cev txo qis tuaj yeem siv los ua qhov kev kho kom txo qis kom tshem tawm cov hlau oxide nyob rau saum npoo ntawm Immersion kub PCB.

Kho qhov vuam kub thiab lub sij hawm los txhim kho qhov zoo ntawm cov pob qij txha. Tom qab lees paub qhov ntsuas kub thiab lub sijhawm, ua cov kev sim thiab tshuaj xyuas ntau zaus kom ntseeg tau tias cov vuam yog raws li tus qauv.

Siv cov tshuaj txhuam hniav tsim nyog los txhim kho qhov zoo ntawm cov pob qij txha. Rau cov khoom uas yooj yim anodized, cov hmoov lead-dawb solder muab tshuaj yog pom zoo. Rau cov khoom uas tsis yooj yim oxidized, cov khoom siv lead ua kua nplaum tuaj yeem siv tau.

Raws li cov ntsiab lus, cov laj thawj rau cov tin tsis zoo ntawm Immersion kub PCB feem ntau yog los ntawm cov yam ntxwv xws li tsis ua tiav kev tu, hlau oxidation, kub tsis sib xws, thiab cov khoom tsis zoo ntawm cov tin. Siv cov kev ntsuas thiab cov txheej txheem tsim nyog, ua tib zoo ntxuav cov phaj kub, ua kom txo qis kev kho mob, ntxiv dag zog rau kev tswj qhov kub thiab txias, thiab xaiv cov khoom zoo tin tuaj yeem daws qhov teeb meem ntawm cov tin tsis zoo ntawm Immersion kub PCB. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov zoo thiab ruaj khov ntawm tin ntawm lub phaj kub, thiab thaum kawg cov khoom siv hluav taws xob zoo tuaj yeem tsim tau.
