Dab tsi yog sib txawv ntawm Lub Tshuab Nqus Tsev Plating Thiab Dej Plating, Dab Tsi Yog Rau IPhone

Dab tsi txawv ntawm plum plating thiab dej plating, dab tsi yog txoj kev rau iPhone

Yog tias ib tug neeg nug koj, dab tsi yog electroplating? Koj yuav hais li cas?

Qee tus hais tias dej plating, qee tus hais tias nqus plating. Qhov twg yog qhov zoo? Qhov tseeb, "electroplating" txhais tau hais tias muaj ntau yam hauv cov lag luam. Piv txwv, hauv kev lag luam mobile xov tooj tam sim no, dej electroplating tsis tshua muaj siv. Hauv ntau tus neeg lub hlwb, electroplating feem ntau yog hais txog lub tshuab nqus tsev vacuum, thaum nyob hauv kev lag luam hauv chav dej, dej electroplating siv dav. Qhov tseeb, dej electroplating feem ntau yog hais txog dej electroplating.

Dej electroplating thiab nqus plating yog cov txheej, peb pib ntawm kev faib tawm ntawm txheej, saib qhov txawv ntawm ntau hom txheej.

Tsim cov khoom tsim tsim

electroplated khoom

Txheej los ntawm molding txoj kev muab faib raws li nram no:

1. Phem theem: ---> kev hloov tshuaj

2. Cov kua ua kua: ---> hloov tshuaj

3. Txoj kev ntsuas huab cua: -> tshuaj hloov thiab hloov lub cev

Cov lus qhia kom ntxaws yog li nram qab no:

plhaub tsim

Cov txheej txheem feem ntau txheej txheem yog: dej electroplating, anodic oxidation, evaporation nqus, xau plating plating, ion plating. Tom ntej no, cov txheej txheem saum toj no yuav piav qhia ib los ntawm ib qho ntawm qhov kev xav ntawm CMF engineer.

Dej electroplating txujci:

Ntsiab lus: anodic dissolution, cathodic adhesion, electrochemical ras txog

Kev siv dej electroplating yog siv los tsim kev siab khwv thiaj muaj cov nyom, ua kom cov txheej nplaum, thiab qhov zoo, yog qhov loj hauv plating, cov nqi qis, cov kev tsis zoo yog cov tshuaj toxicity ntawm electrolyte, muaj pa phem.

Dej electroplating ntau lawm kab

Anodic oxidation:

Ntsiab lus: hlau oxidation zaj duab xis, hluav taws xob tshuaj

Anodic oxidation kuj tuaj yeem ua tau rau hauv Ta2O2, TiO2, ZrO2, Nb2O5, HfO2, WO3, thiab lwm yam, uas yog siv los ua ib cov yeeb yaj kiab los sis cov nkauj tha xim.

Anodized khoom

Nqus evaporation tseem hu ua thermal evaporation

Txoj kev tseem ceeb lo lus: siab kub evaporation, tom qab tso dej coated

Lub tshuab nqus tsev qhuav yuav muab faib ua hom ntawm cov cua sov thiab cov cua kub ncaj qha nyob ntawm seb cua sov hom yeeb yaj kiab.

1. Txwv tsis pub muaj cua sov: tsuas yog rau cov evaporation khoom cua sov, tsis pub cov khoom siv rau cov khoom siv rau ntawm tshav kub;

2. Kev siv cua sov ncaj qha: siv cov khoom siv hluav taws xob (electron beam, plasma los yog laser) los yog siab, cov khoom siv yeeb yaj kiab ncaj nraim rau cov evaporation source no thiab ua cua txias;

* Txhob kom tsis txhob evaporation ntawm lub hauv paus (thawv) nrog rau cov khoom siv zaj duab xis, lub ntsiab lus ntawm qhov khoom siv yuav tsum yog siab tshaj lub ntsiab ntawm cov yeeb yaj kiab.

Evaporation txujci

Kev ua kom cua sov evaporation

Lub zog thermal generated los ntawm qhov tam sim no hla los ntawm qhov kev siv yog siv los ntawm cov cua kub nyhav khoom. Tus ntaus ntawv yog raws li nram no:

Kev ua kom cua sov evaporation

Disadvantages ntawm kuj cua sov txoj kev:

1. Kub lub tshav kub ua ntej thiab tom qab muab cov cua sov tso rau hauv zaj duab xis. Qhov evaporating qhov chaw yuav nkag tau yooj yim nrog cov khoom lossis tsa qee yam tsis txaus ntseeg;

2. Vim tias tsuas yog tshav kub ntawm cov khoom cua evaporation, feem ntau cov oxides uas muaj qhov chaw siab melting tsis tuaj yeem raug fused thiab ua kom qhuav;

3. Tsawg evaporation ceev;

4. Yog hais tias cov khoom siv lo yog ib qho lag luam, nws yuav tau decomposed;

5. Zaj duab xis tsis yog qhov nyuaj, tsis yog qhov siab, tsis zoo.

sputtering

Ntsiab lus: ionized inert pa bombarding phiaj, phiaj ntog, deposition, txias thiab zaj duab xis sib sau

Lub hauv paus ntawm lub tshuab ua kom tshuab pa yog qhov ua kom siv pa tawm hauv lub tshuab nqus tsev, ncaj qha los ntawm cov khoom siv (lub hom phiaj) raws li cov electrodes, siv cov electrodes saib hluav taws xob 5 kv ~ 15 kv plasma bombardment ntawm cov khoom siv, qhov cua hauv qhov qub, roj ionization, tsiv raws li cov ntsiab lus hauv plasma, ion feem cuam cov khoom siv thiab cov khoom atoms uas tso rau saum npoo av, txias qhov condensed rau hauv ib zaj duab xis.

Magnetron sputtering

Nyob rau ntawm lub hauv paus ntawm dc sputtering los yog rf sputtering, cov qauv electrode raug khees me ntsis lawm, uas yog, ib qho chaw ruaj khov hauv nruab nrab ntawm cov cathode, thiab cov kev taw qhia ntawm cov hlau nplaum yog lub nraub qaum rau cov kev coj ntawm cov hluav taws xob hauv qhov tsaus nti, thiaj li hais tias lub zog ntawm cov nqi raug tiv thaiv tau khi tau los ntawm kev sib nqus field. Qhov no yog txoj kev hu ua magnetron sputtering

Schematic daim duab ntawm magnetron sputtering

Txij li cov quab yuam ntawm cov hlau nplaum yog ib qho rau cov kev taw qhia ntawm lub tshuab hluav taws xob, qhov centripetal quab yuam ntawm electron cyclotron pob zeb yuav raug tsim. Nyob rau lub sij hawm no, qhov kev sib tsoo ntawm kev sib tsoo nruab nrab ntawm hom tsis muaj zog yuav nce, thiab cov yeeb yaj kiab tau ua rau siab ceev.

Ntxiv rau qhov siab, qhov ob qhov zoo ntawm magnetron sputtering yog kev kub ceev thiab tsis tshua muaj kub, yog li nws tseem hu ua kev kub ceev thiab tsis tshua muaj cua sov.

Tab sis magnetron sputtering kuj muaj qee qhov teeb meem, xws li kev siv hlau nplaum hluavtaws hluav taws xob, electrode magnetic tswj electrode, lub ntsiab ntawm lub hauv paus thiab peripheral tsis yog perpendicular mus rau qhov sib txuam ntawm cov hluav taws xob ntau dua thiab me me, piv txwv li thaum uas tig mus rau qhov chaw ntawm magnetic field tiv thaiv kab mob me me, nyob hauv ib cheeb tsam ntawm qhov chaw ntawm cov khoom siv los ntawm kev ua pa ceev nrawm, thaum nruab nrab thiab ntug nqaj qis dua, yog li nws yuav yog lub vos zoo li erosional hav, txo cov nqi ntawm cov khoom siv khoom, thiab yuav cuam tshuam zaj yeeb yaj kiab.

Ion plating

Ntsiab lus: nqus cov pa tawm, tawm mus rau qhov chaw tawm, kev ua npau av substrate

Lub hauv paus ntsiab lus tseem ceeb yog siv cov pa roj paug tshwm sim, cov khoom siv zaj duab xis tso rau hauv ion xeev, thiab ces tso rau hauv cov substrate.

Qhov txheej txheem kaw lus ntawm ion plating yog PVD qhov system, tiam sis cov roj reactive yog ntxiv los ua kom hnov mob nrog cov khoom siv zaj duab xis tom qab evaporation thiab ces tso nyiaj rau hauv lub substrate los tsim txuas. Yog li ntawd, qhov muaj pes tsawg leeg ntawm zaj duab xis txheej yog txawv ntawm thawj zaj duab xis cov khoom thiab yog ib qho chaw ntawm lub substrate phiaj khoom.

Ion plating yeej muaj peb kauj ruam:

1. Tig xa cov kabmob hauv lub cev los ua cov kabmob muaj zog: muaj ntau yam evaporation thiab cov tshuab kev ywj pheej yauv siv tau rau qhov nqus evaporation kom ua tiav lub hom phiaj no;

2. Hloov cov thev glandous rau hauv cov xeev hauv xeev los mus txhim kho qhov degree ionization ntawm cov ntaub ntawv raw (feem ntau li 1%): ntau yam ion ntsiab lus siv tau los hloov cov zog rau raw cov ntaub ntawv kom ncav cuag cov degree ionization;

3. Txhim khu lub zog uas nqa los ntawm cov khoom siv hauv Xionic xeev los txhim kho qhov zoo ntawm zaj yeeb yaj kiab: kev muaj peev xwm los mus ceev cov ions tau los ntawm kev ntxiv qhov tsim nyog tsis zoo rau lub hauv paus.

Ntsiab cai ntawm ion plating

Cov yam ntxwv ntawm ion plating yog raws li nram no:

1. Ion plating yuav nqa tawm ntawm qhov kub tsis txias ntawm 600 degrees;

2. Zoo adhesion;

3. Zoo-diffracted - hluav taws xob electropositive ncav cuag tag nrho cov txheej txheem yooj yim thiab tso cov txheej;

4. Qhov ceev ceev yog ceev ceev, txog li 5 ~ 5um, thaum lub sij hawm sib zog ntawm kev ua phaj feem ntau ntawm cov phaj siab tsuas yog 0.01 ~ 1,0um / min;

5. Kev xaiv ntau txog kev ua haujlwm thiab cov ntaub ntawv pov thawj, nrog rau hlau, tais kabmov, iav thiab plastics, thiab xaiv ntau hauv cov ntaub ntawv ua yeeb yaj kiab, nrog rau cov hlau, cov hlau ntoo thiab cov tshuaj.
