Kev lag luam hluav taws xob thiab khoom siv hluav taws xob tsim khoom lag luam yog ntau hom kev lag luam.Nws suav nrog ntau yam kev lag luam thiab thev naus laus zis nrog rau saum npoo ntawm cov hlau lead-dawb soldering rau cov khoom siv semiconductor.Txawm hais tias koj lub tuam txhab ua haujlwm li cas, lub tshuab hluav taws xob nitrogen hauv tsev muab ntau yam txiaj ntsig rau kev lag luam hluav taws xob.Nitrogen nyob rau hauv nws daim ntawv purest yog ib tug inert tsis-conductive gas.Nws yog siv los txiav oxidation thaum lub sij hawm ntim thiab sib dhos ntawm cov khoom siv hluav taws xob.Ntawm no peb yuav piav qhia luv luv txog ntau yam kev siv ntawm cov tshuab hluav taws xob nitrogen hauv kev lag luam hluav taws xob.
Atmospheric sib xws
Ntau cov txheej txheem tsim hluav taws xob xav tau kev tswj hwm ib puag ncig xws li kub thiab av noo.Nitrogen, ua ib qho roj inert, tuaj yeem muab cov huab cua zoo ib yam hauv cov khoom siv hluav taws xob tsim khoom.Nitrogen ua kom cov huab cua nyob ruaj khov, thiab nws tuaj yeem txo qhov muaj feem cuam tshuam los ntawm cov dej noo ntau dhau, uas ua rau oxidation.
Mitigation ntawm oxidation
Ntau cov khoom siv hluav taws xob xav tau cov pob qij txha muaj zog los xyuas kom muaj kev ruaj ntseg ntev thiab kev tsim khoom zoo.Thaum lub sij hawm txheej txheem ntawm soldering, cov pa oxygen tuaj yeem ua rau oxidation.Oxidation yog ib qho tseem ceeb cuam tshuam kev tsim cov nroj tsuag;nws ua rau cov pob qij txha tsis muaj zog ua rau muaj qhov tsis xws luag, ua rau cov khoom siv tsis zoo.
Cov teeb meem no tuaj yeem zam tau los ntawm kev siv cov tshuab hluav taws xob nitrogen los tsim cov roj nitrogen ntshiab hauv cov txheej txheem tsim khoom siv hluav taws xob.Nitrogen txo qhov kev pheej hmoo ntawm oxidation thiab tso cai rau kev ntub dej ntawm cov solder thiab cov khoom siv uas nws siv rau.Nws kuj tsim kom muaj zog solder pob qij txha uas ua rau cov khoom siv hluav taws xob siv tau ntev thiab zoo.
Kev txo qis
Tin-lead solder muaj ntau yam txaus ntshai;Yog li ntawd, ntau lub tuam txhab tsim hluav taws xob nyiam siv cov hlau lead-dawb solder.Txawm li cas los xij, qhov kev xaiv no los nrog ob peb qhov tsis zoo.Tus nqi ntawm cov khoom siv hluav taws xob tsis muaj hlau lead yog qhov siab heev.solder yam tsis muaj txhuas muaj qhov melting ntau dua;qhov no tsim dross.Dross yog ib qho khoom pov tseg uas tsim rau ntawm qhov chaw ntawm molten solder.
Dross yuav tsum tau ua kom huv si tsis tu ncua kom ntseeg tau tias cov txiaj ntsig zoo kawg, uas ntxiv rau kev siv cov hlau lead-free solder hauv cov khoom siv hluav taws xob.Onsite Nitrogen generators tuaj yeem txo qhov tsim ntawm cov khoom siv hluav taws xob ntau txog 50%, txhim kho cov khoom zoo thiab txiav lub sij hawm yuav tsum tau ntxuav cov dross thiab lwm yam pov tseg los ntawm solder.
Nto nro txo
Nitrogen generator daim ntawv thov siv nyob rau hauv kev lag luam hluav taws xob tsim ib puag ncig zoo rau cov txheej txheem, txhim kho kev tsim khoom.
Nitrogen roj tuaj yeem txo qhov nro ntawm cov solder, tso cai rau nws ua kom huv si los ntawm qhov chaw salting-qhov zoo ntawm Nitrogen ua rau cov txheej txheem ntau dua ntawm kev tsim khoom siv hluav taws xob.
Puas yog koj lub chaw tsim khoom yuav tsum hloov mus rau nitrogen tiam hnub no?
Puas yog koj tab tom nrhiav kom txo koj cov nqi ua haujlwm los ntawm nitrogen generator?
Koj puas xav nce qhov zoo ntawm koj cov khoom siv hluav taws xob hauv koj lub lag luam?
Compressed Gas Technologies muaj cov khoom siv hluav taws xob hauv tsev rau cov khoom siv hluav taws xob tsim hluav taws xob thiab kev lag luam.Sihope muab ntau yam kev lag luam-ua PSA thiab membrane generators uas pab cov hluav taws xob tsim kev lag luam nce kev tsim khoom thiab cov nyiaj tau los.
Yog xav paub ntxiv txog kev siv nitrogen tiam thiab kev tsim hluav taws xob, tshawb xyuas peb lub vev xaib.Peb pab pawg kws tshaj lij tau npaj los teb cov lus nug thiab pab koj xaiv cov txheej txheem nitrogen kom raug rau koj lub lag luam.
