Ukuthotywa kweTreatment yeFoil yeCopper eQingiweyo: Inkqubo engundoqo kunye neSiqinisekiso esiPhambili sokuTyala kunye nokuSebenza kwe-Thermal Lamination

Ifoyile yobhedu eqengqelekisiweyoyimathiriyeli engundoqo kwishishini lesekethe ye-elektroniki, kwaye umphezulu wayo kunye nococeko lwangaphakathi lumisela ngokuthe ngqo ukuthembeka kweenkqubo ezisezantsi ezifana nokugquma kunye ne-thermal lamination. Eli nqaku lihlalutya indlela apho unyango lokuthotywa kwegrisi luphucula ukusebenza kwefoyile yobhedu esongiweyo ukusuka kwimveliso kunye nemibono yesicelo. Ukusebenzisa idatha yokwenyani, ibonisa ukulungelelaniswa kwayo kwiimeko zokulungisa ubushushu obuphezulu. I-CIVEN METAL iye yaphuhlisa inkqubo ye-proprietary deep degreasing etyhutyha iibhotile zeshishini, ibonelela ngezisombululo ezithembekileyo zefoyile yobhedu kwimveliso ye-elektroniki ephezulu.

1. Undoqo weNkqubo yoKuthotywa: Ukususwa kabini koMphezulu kunye neGrisi yangaphakathi

1.1 Imiba ye-Oli eyiNtsalela kwiNkqubo yokuQhutywa

Ngethuba lokuvelisa i-foil yobhedu ephothiweyo, iingots zethusi zihamba ngamanyathelo amaninzi ajikelezayo ukuze zenze izinto ze-foil. Ukunciphisa ubushushu obuguquguqukayo kunye nokuguga, izithambiso (ezifana neoyile yeminerali kunye ne-synthetic esters) zisetyenziswa phakathi kweeroli kunyeifoyile yobheduumphezulu. Nangona kunjalo, le nkqubo ikhokelela ekugcinweni kwegrisi ngeendlela ezimbini eziphambili:

• I-adsorption yomphezulu: Ngaphantsi koxinzelelo lwe-rolling, ifilimu ye-oyile ye-micron-scale (0.1-0.5μm ubukhulu) ibambelela kwindawo yobhedu yobhedu.
• Ukungena kwangaphakathi: Ngexesha lokuguqulwa kwe-rolling, i-lattice yethusi ivelisa iziphene ze-microscopic (ezifana ne-dislocation kunye ne-voids), ivumela iamolekyu zegrisi (i-C12-C18 i-hydrocarbon chains) ukuba ingene kwi-foil nge-capillary action, ifikelele kubunzulu be-1-3μm.

1.2 Unyino kwiiNdlela zokuCoca ngokweSintu

Iindlela eziqhelekileyo zokucoca umphezulu (umzekelo, ukuhlamba i-alkaline, ukosula utywala) susa kuphela iifilimu ze-oyile ezingaphezulu, ukuzuza umlinganiselo wokususwa malunga70-85%, kodwa ayisebenzi ngokuchasene negrisi efunxelwe ngaphakathi. Idatha yovavanyo ibonisa ukuba ngaphandle kokunciphisa okunzulu, igrisi yangaphakathi iphinda ivele kumphezulu emvaImizuzu engama-30 kwi-150°C, ngomlinganiselo wokubekwa kwakhona kwe0.8-1.2g/m², ebangela “ungcoliseko lwesibini.”

1.3 UkuPhumelela kweTekhnoloji kwi-Deep Degreasing

I-CIVEN METAL iqeshe a"Ukukhutshwa kweekhemikhali + ukusebenza kwe-ultrasonic"inkqubo edibeneyo:

1. Ukutsalwa kweekhemikhali: I-agent ye-chelating yesiko (pH 9.5-10.5) ichitha iimolekyuli zegrisi ezinde, zenze ii-complexes ezinyibilikayo zamanzi.
2. Uncedo lwe-ultrasonic: I-40kHz i-high-frequency ultrasound ivelisa iziphumo ze-cavitation, ukuphula amandla okubopha phakathi kwegrisi yangaphakathi kunye ne-lattice yethusi, ukuphucula ukusebenza kakuhle kwe-grease dissolution.
3. Ukomisa ngevacuum: Ukuphelelwa amanzi ngokukhawuleza kwi -0.08MPa uxinzelelo olubi luthintela i-oxidation.

Le nkqubo inciphisa intsalela yegrisi≤5mg/m²(edibana nemigangatho ye-IPC-4562 ye-≤15mg/m²), ukuphumeza> I-99% yokususa ukusebenza kakuhleyegrisi efunxelwe ngaphakathi.

2. Impembelelo eNgqongileyo yoNyango lwe-Degreasing kwi-Coating kunye ne-Thermal Lamination Processes

2.1 Ukwandiswa kweAdhesion kwi-Coating Applications

Izinto zokugquma (ezifana nokuncamatheliswa kwePI kunye neefotoresist) kufuneka zenze iibhondi zomgangatho wemolekyuli kunyeifoyile yobhedu. Igrisi eshiyekileyo ikhokelela kule miba ilandelayo:

• Ukunciphisa amandla angaphakathi: I-hydrophobicity yegrisi inyusa i-angle yoqhagamshelwano yezisombululo zokwaleka ukusuka15 ° ukuya kuma-45 °, ukuthintela ukumanzisa.
• Ukuhlanganiswa kweekhemikhali ezithintelweyo: Umaleko wegrisi uvimba amaqela e-hydroxyl (-OH) kumphezulu wobhedu, ukuthintela ukuphendula ngamaqela asebenzayo eresin.

Ufaniso lweNtsebenzo ye-Degreased vs.

2.2 Ukwandiswa kokuNthemba kwi-Thermal Lamination

Ngexesha lobushushu obuphezulu (180-220 ° C), igrisi eshiyekileyo kwifoyile yobhedu eqhelekileyo ikhokelela kwiintsilelo ezininzi:

• Ukuqulunqwa kwebhabhula: Igrisi engumphunga iyadala10-50μm amaqamza(ubuninzi>50/cm²).
• I-Interlayer delamination: Ukuthambisa kunciphisa amandla e-van der Waals phakathi kwe-epoxy resin kunye nefoyile yobhedu, yehlisa amandla e-peel ngo.30-40%.
• Ilahleko yeDielectric: Igrisi yamahhala ibangela ukuguquguquka rhoqo kwe-dielectric (i-Dk variation> 0.2).

Emva kokoIiyure ze-1000 ze-85 ° C / 85% ukuguga kwe-RH, CIVEN METALIfoyile yobheduimiboniso:

• Ukuxinana kwebhamuza: <5/cm² (umndilili weshishini>30/cm²).
• Amandla e-Peel: Uyayigcina1.6N/cm(ixabiso lokuqala1.8N/cm, izinga lokuthotywa kwe-11% kuphela.
• Ukuzinza kweDielectric: Ukwahluka kukaDkt ≤0.05, intlanganisoIimfuno ze-5G millimeter-wave frequency.

3. Ubume boShishino kunye neNdawo eBenchmark yeCIVEN METAL

3.1 Imingeni yoShishino: Ukwenziwa lula kweNkqubo eqhutywa ziindleko

NgaphezuluI-90% yabenzi befoyile yobhedu eqengqelekayoukwenza lula ukusetyenzwa ukuze kucuthwe iindleko, ngokulandela inkqubo esisiseko:

Ukuqengqeleka → Ukuhlamba ngamanzi (Na₂CO₃ isisombululo) → Ukomisa → Ukujija

Le ndlela isusa kuphela igrisi yomphezulu, kunye nokuguquguquka kwe-post-wash surface resistivity ye±15%(Inkqubo yeCIVEN METAL igcinwa ngaphakathi±3%).

3.2 Inkqubo yoLawulo loBulunga yeCIVEN METAL “Zero-Defect”

• Ukubeka iliso kwi-Intanethi: Uhlalutyo lwe-X-ray fluorescence (XRF) lwexesha langempela lokubona izinto ezishiyekileyo zomhlaba (S, Cl, njl.).
• Uvavanyo lokuguga olukhawulezileyo: Ukulinganisa ngokugqithisileyo200°C/24hiimeko zokuqinisekisa ukuba igrisi enguziro iyavela kwakhona.
• Ukulandeleka kwenkqubo epheleleyo: Uluhlu ngalunye lubandakanya ikhowudi ye-QR edibanisa nayoIiparamitha zenkqubo engundoqo ezingama-32(umzekelo, ukwehla kweqondo lokushisa, amandla e-ultrasonic).

4. Isiphelo: Unyango lwe-Degreasing-Isiseko se-High-End Electronics Manufacturing

Ukunyangwa kwe-deep degreasing ye-foil yobhedu ephothiweyo ayikho nje inkqubo yokuphucula kodwa ukulungelelanisa ukucinga kwangaphambili kwizicelo ezizayo. Itekhnoloji ye-CIVEN METAL yokuphumelela iphucula ukucoceka kwefoyile yobhedu ukuya kwinqanaba leathomu, ukubonelelaisiqinisekiso somgangatho wezinto eziphathekayongenxauqhagamshelwano oluphezulu (HDI), iisekethe eziguquguqukayo zeemoto, kunye namanye amasimi aphezulu.

KwiIxesha le-5G kunye ne-AIoT, iinkampani kuphela ezilawulayoitekhnoloji yokucoca engundoqoinokuqhuba izinto ezintsha ezizayo kwishishini lefoyile yobhedu ye-elektroniki.
