Los ntawm kev pom ntawm kev ua lag luam tam sim no, sodium persulfate (SPS Persulfate (SPSS) yog kev tsim ib txoj haujlwm tseem ceeb dua hauv kev kho cov hlau nto. Nws cov ntawv thov muaj ntau thiab mus deb, xws li los ntawm precision microDabrication nyob rau hauv semiconductor board (PCB) kev tsim khoom thiab ntau yam kev tsim khoom lag luam.
Raws li kev txhim kho thev naus laus zis txuas ntxiv thiab cov ntawv thov ua haujlwm tshiab Txawm hais tias lub chaw ua lag luam tam sim no tseem ruaj khov, muab kev txhawb nqa ruaj khov rau kev lag luam, sab nraud xws li cov khoom nyoos tau hloov pauv, muaj peev xwm ua rau kev hloov kho nqe. Yog li, tswj hwm kev pom kev nkag siab rau kev ua lag luam kev ua lag luam yuav yog qhov tseem ceeb rau kev txhim kho cov khoom ruaj khov thiab muaj kev ruaj ntseg.
I. Sodium Persulfate (SPS): Txhawb Nqa Cov Hlau Nto Kho
1. Txav kom huv thiab ua kom muaj cov hlau sib tsoo
Nyob rau hauv precision hlau ua, SPAN ua haujlwm ua ib tus neeg sawv cev ua tau zoo nrog cov khoom muaj zog oxidative thaj chaw. Nws tau tshem tawm cov khoom siv tawv ncauj ua ke xws li roj, xeb, thiab oxides los ntawm cov hlau, tawm hauv lawv lub siab dua. Qhov kev kho no txhim kho cov microstructure ntawm qhov chaw, muab lub hauv paus zoo tshaj plaws rau cov txheej txheem txuas ntxiv lossis cov electroplating. Los ntawm kev txhim kho cov nplaum ntawm cov txheej thiab cov hlau substrate, sps tsis yog ua kom zoo nkauj thiab ua rau cov khoom lag luam zoo thiab ua tau zoo.
2. Cov khoom sib xyaw ntawm cov tswv yim etching
Hauv cov kev tsim hluav taws xob siab ua haujlwm, xws li cov pcb ntau lawm, SPAN ua lub luag haujlwm tseem ceeb hauv kev etching cov txheej txheem. Nws ua kom meej meej tswj ntawm etching tob thiab thaj tsam, txhawm rau txhim kho cov qauv hluav taws xob thiab kev ua tau zoo thiab kev ntseeg tau ntawm cov khoom hluav taws xob. Ntxiv mus, sps lub peev xwm txuas ntxiv mus txuas ntxiv rau ntau yam ntawm cov ntaub ntawv hlau, nthuav dav cov peev txheej rau kev ua hlau.
3. Kev ua kom zoo rau cov hlau nto
Los ntawm kev hloov kho saum npoo siv SPS, cov hlau tuaj yeem tsim kho cov roj oxide muaj zog. Cov txheej no ua cov ntaub thaiv xeb-resistant, zoo tiv thaiv cov hlau los ntawm kev txhim kho lawv lub hardness thiab hnav tsis kam, yog li ncua lawv kav. Ib qho ntxiv, los ntawm kev kho cov txheej txheem kho mob, SPECS tso cai rau kev tswj hwm yooj yim ntawm cov kev daws teeb meem saum npoo av, muab cov kev daws teeb meem.
4. Tus ntsuab additive rau cov khoom siv hlau zoo
Nyob rau hauv teb rau qhov kev cog lus rau cov peev txheej kev pab, SPS ua haujlwm ua tus neeg sawv cev oxidization hauv cov khoom siv hluav taws xob. Nws tau rov qab siv dua tshiab thiab rov qab siv cov peev txheej no, ua si lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev lag luam ncig. Tsis tas li ntawd, ua rau muaj kev cuam tshuam los ntawm cov tshuaj tsawg kawg, uas yog qhov yooj yim los tswj, ua raws li cov qauv ntawm Green Chemistry thiab kev txhim kho kom muaj kev loj hlob.
Ii. Cov chaw muag khoom tshaj lij: ib qho chaw ruaj khov rau qhov zoo thiab kev nyab xeeb
Cov toj roob hauv pes ua lag luam rau kev kho cov hlau nto sib txawv yog kom muaj kev cuam tshuam los ntawm cov khoom xa-sab dynamics. Rau qhov kev sib tw no, cov tub ntxhais kev sib tw ntawm cov khoom lag luam nyob hauv kev ua kom cov khoom lag luam zoo, thiab tswj kev tswj hwm tus nqi. Ntawm cov neeg sib tw ua lag luam, muaj peev xwm los tsim kho tshiab thiab tswj cov nqi tau ua tus txiav txim siab rau kev ua tiav.
Tag
Sodium Persulfate (SPPS), raws li kev kho mob hlau saum npoo av, tau dhau los ua kev siv tshuaj rau kev siv tshuaj thiab kev siv tshuaj tshwj xeeb thiab cov khoom siv uas muaj txiaj ntsig zoo. Hauv xyoo tom ntej, kev thov cov kev cia siab ntawm SPECT hauv kev kho hlau saum npoo av yuav tsum nthuav ntxiv.
