Unyango lokususa amafutha kwi-Rolled Copper Foil: Inkqubo ePhambili kunye noQinisekiso oluPhambili lokuGcoba kunye nokusebenza kwe-Thermal Lamination

Ifoyile yobhedu eqengqekileyosisixhobo esiphambili kushishino lwesekethe ye-elektroniki, kwaye umphezulu wayo kunye nokucoceka kwangaphakathi kumisela ngokuthe ngqo ukuthembeka kweenkqubo ezisezantsi ezifana nokugquma kunye nokugquma okushushu. Eli nqaku lihlalutya indlela unyango lokususa amafutha oluphucula ngayo ukusebenza kwefoyile yobhedu eqengqiweyo ukusuka kwimveliso kunye nembono yesicelo. Isebenzisa idatha yokwenyani, ibonisa ukuba iyakwazi ukuziqhelanisa neemeko zokucubungula amaqondo obushushu aphezulu. I-CIVEN METAL iphuhlise inkqubo yokususa amafutha enzulu eqhekeza imiqobo kushishino, ibonelela ngezisombululo zefoyile yobhedu ezithembekileyo kakhulu kwimveliso ye-elektroniki ephezulu.

1. Undoqo weNkqubo yokususa amafutha: Ukususwa kabini komphezulu kunye negrisi yangaphakathi

1.1 Iingxaki zeoyile eseleyo kwiNkqubo yokuqengqeleka

Ngexesha lokuveliswa kwe-copper foil egoqiweyo, ii-copper ingots zihamba ngamanyathelo amaninzi okugoqa ukwenza izinto ze-foil. Ukunciphisa ubushushu bokungqubana kunye nokuguguleka kwe-roll, kusetyenziswa izinto zokuthambisa (ezifana nee-mineral oils kunye nee-synthetic esters) phakathi kwe-rolls kunye ne-ifoyile yobheduNangona kunjalo, le nkqubo ikhokelela ekugcinweni kwamafutha ngeendlela ezimbini eziphambili:

• Ukufunxwa komphezulu: Phantsi koxinzelelo oluqengqelekayo, ifilimu yeoyile ye-micron-scale (ubukhulu obuyi-0.1-0.5μm) inamathela kumphezulu wefoyile yobhedu.
• Ukungena ngaphakathi: Ngexesha lokuguqulwa kwe-rolling, i-lattice ye-copper ivelisa iziphene ezincinci (ezifana nokudilika kunye ne-voids), okuvumela iimolekyuli zegrisi (ii-C12-C18 hydrocarbon chains) ukuba zingene kwi-foil nge-capillary action, zifikelele kubunzulu be-1-3μm.

1.2 Imida yeendlela zokucoca zesintu

Iindlela eziqhelekileyo zokucoca umphezulu (umz., ukuhlamba nge-alkaline, ukusula ngotywala) ukususa iifilimu zeoyile yomphezulu kuphela, nto leyo efikelela kwinqanaba lokususa elimalunga70-85%, kodwa azisebenzi ngokuchasene negrisi efunxwayo ngaphakathi. Idatha yovavanyo ibonisa ukuba ngaphandle kokususa igrisi nzulu, igrisi yangaphakathi iphinda ivele phezu komhlaba emva kokubaImizuzu engama-30 kwi-150°C, kunye nezinga lokuphinda kufakwe0.8-1.2g/m², okubangela "ungcoliseko lwesibini."

1.3 Uphuhliso lweTekhnoloji ekuSuseni amafutha ngokunzulu

I-CIVEN METAL isebenzisa"Ukukhupha iikhemikhali + ukusebenza kwe-ultrasonic"inkqubo edibeneyo:

1. Ukukhupha iikhemikhali: I-arhente ye-chelating eyenzelwe wena (pH 9.5-10.5) ibola iimolekyuli zegrisi ezinemixokelelwane emide, zenze iicomplexes ezinyibilikayo emanzini.
2. Uncedo lwe-ultrasound: I-ultrasound ephezulu ye-40kHz ivelisa iziphumo ze-cavitation, iphula amandla okubopha phakathi kwegrisi yangaphakathi kunye ne-lattice yobhedu, iphucula ukusebenza kakuhle kokunyibilika kwegrisi.
3. Ukomisa nge-vacuum: Ukuphelelwa ngamanzi ngokukhawuleza xa uxinzelelo olubi lwe -0.08MPa luthintela i-oxidation.

Le nkqubo inciphisa intsalela yamafutha ukuya≤5mg/m²(ukuhlangabezana nemigangatho ye-IPC-4562 ye-≤15mg/m²), ukufikelela>99% ukusebenza kakuhle kokususaukuze kufunxwe igrisi ngaphakathi.

2. Impembelelo ethe ngqo yoNyango lokuSusa amafutha kwiinkqubo zokuGcoba kunye nokuLamination kobushushu

2.1 Ukuphuculwa kokuncamathelisa kwizicelo zokugquma

Izinto zokugquma (ezifana nezincamathelisi ze-PI kunye ne-photoresists) kufuneka zenze iibhondi ze-molecular-level kunyeifoyile yobheduIgrisi eseleyo ikhokelela kwezi ngxaki zilandelayo:

• Ukunciphisa amandla okunxibelelana: Ukungangeni kwamanzi kwegrisi kwandisa i-engile yoqhagamshelwano lwezisombululo zokugquma ukusuka15° ukuya kwi-45°, ethintela ukumanzisa.
• Ukubopha iikhemikhali okuthintelweyo: Umaleko wegrisi uvimba amaqela e-hydroxyl (-OH) kumphezulu wobhedu, uthintela ukusabela kwamaqela asebenzayo e-resin.

Uthelekiso Lokusebenza Kwefoyile Yekopolo Eyehlisiweyo Ukuthelekiswa Nefoyile Yekopolo Eqhelekileyo:

2.2 Ukuthembeka Okuphuculweyo kwi-Thermal Lamination

Ngexesha lokulamina ngobushushu obuphezulu (180-220°C), igrisi eseleyo kwifoyile yobhedu eqhelekileyo ikhokelela kwiingxaki ezininzi:

• Ukwakheka kwamaqamza: Igrisi ephekiweyo idalaAmaqamza ayi-10-50μm(ubuninzi >50/cm²).
• Ukwahlulwa kwe-interlayerIgrisi inciphisa amandla e-van der Waals phakathi kwe-epoxy resin kunye ne-copper foil, inciphisa amandla e-reel nge30-40%.
• Ukulahleka kweDielectric: Igrisi ekhululekileyo ibangela ukuguquguquka okungaguqukiyo kwe-dielectric (utshintsho lwe-Dk >0.2).

EmvaIiyure ezili-1000 zokuguga kwe-RH ezingama-85°C/85%, Isinyithi seCivenIfoyile yeCopperimiboniso:

• Uxinano lwamaqamza: <5/cm² (umndilili weshishini >30/cm²).
• Amandla okuxobula: Igcina1.6N/cm(ixabiso lokuqala1.8N/cm, izinga lokuwohloka kwexabiso liyi-11% kuphela.
• Uzinzo lweDielectric: Utshintsho lweDk ≤0.05, intlanganisoIimfuno zefrikhwensi yamaza e-5G millimeter.

3. Isimo soShishino kunye neSikhundla seCIVEN METAL

3.1 Imingeni yoShishino: Ukulula kwenkqubo okuqhutywa ziindleko

PhezuI-90% yabavelisi befoyile yobhedu egoqiweyoukwenza kube lula ukucubungula ukuze kuncitshiswe iindleko, kulandela indlela esisiseko yokusebenza:

Ukuqengqeleka → Ukuhlamba Ngamanzi (isisombululo seNa₂CO₃) → Ukomisa → Ukujija

Le ndlela isusa kuphela igrisi yomphezulu, kunye nokuguquguquka kokumelana komphezulu emva kokuhlamba±15%(Inkqubo yeCIVEN METAL iqhubeka ngaphakathi±3%).

3.2 Inkqubo yoLawulo loMgangatho “ongenasiphene” yeCIVEN METAL

• Ukubeka esweni kwi-intanethi: Uhlalutyo lwe-X-ray fluorescence (XRF) lokufumanisa izinto eziseleyo kumphezulu ngexesha langempela (S, Cl, njl.njl.).
• Uvavanyo lokwaluphala olukhawulezileyo: Ukulinganisa okugqithisileyo200°C/24hiimeko zokuqinisekisa ukuba akukho grisi iphinda ivele.
• Ukulandeleka kwenkqubo epheleleyo: Uluhlu ngalunye luquka ikhowudi ye-QR edibanisaIiparameter zenkqubo eziphambili ezingama-32(umz., ubushushu bokususa amafutha, amandla e-ultrasound).

4. Isiphelo: Unyango Lokususa Amafutha—Isiseko Sokwenziwa Kwezinto Ze-elektroniki Ezikumgangatho Ophezulu

Unyango olucociweyo lwe-copper foil olugoqiweyo aluyonto nje yokuphucula inkqubo kodwa yindlela yokucinga kwangaphambili ukuze isetyenziselwe ukusetyenziswa kwixesha elizayo. Itekhnoloji entsha ye-CIVEN METAL iphucula ukucoceka kwe-copper foil ukuya kwinqanaba le-athomu, nto leyo ebonelelaisiqinisekiso senqanaba lezinto eziphathekayongenxaii-interconnects ezinoxinano oluphezulu (i-HDI), iisekethe eziguquguqukayo zeemoto, kunye nezinye iinkalo eziphezulu.

KwiIxesha le-5G kunye ne-AIoT, ziinkampani kuphela ezikwaziyo ukwenza izinto kakuhleubuchwepheshe bokucoca obuphambiliinokuqhuba izinto ezintsha kwixesha elizayo kwishishini le-elektroniki le-copper foil.
