Ukwelashwa Kokususa Amafutha Kwe-Roll Copper Foil: Inqubo Eyinhloko kanye Nokuqinisekiswa Okubalulekile Kokumboza kanye Nokusebenza Kokumboza Okushisayo

Ifoyili yethusi eligoqiweiyinto ebalulekile embonini yesekethe kagesi, futhi ukuhlanzeka kwayo okuphezulu kanye nobuso bayo kunquma ngqo ukuthembeka kwezinqubo ezingezansi ezifana nokumboza kanye ne-thermal lamination. Lesi sihloko sihlaziya indlela yokwelapha ukukhipha amafutha okwenza ngcono ukusebenza kwe-copper foil egoqiwe kusukela kokubili ekukhiqizeni nasekusetshenzisweni. Isebenzisa idatha yangempela, ikhombisa ukuzivumelanisa kwayo nezimo zokucubungula ezishisa kakhulu. I-CIVEN METAL ithuthukise inqubo yokususa amafutha ejulile ehlukanisa imingcele embonini, inikeze izixazululo ze-copper foil ezinokwethenjelwa kakhulu zokukhiqiza nge-elekthronikhi ephezulu.

1. Umongo Wenqubo Yokususa Amafutha: Ukususwa Okubili Komphezulu Nokugcotshwa Kwangaphakathi

1.1 Izinkinga Zamafutha Asele Enqubweni Yokugoqa

Ngesikhathi sokukhiqizwa kwe-foil yethusi egoqiwe, ama-ingot ethusi adlula ezinyathelweni eziningi zokugoqa ukuze akhe izinto ze-foil. Ukuze kuncishiswe ukushisa okungqubuzanayo kanye nokuguguleka kwe-roll, kusetshenziswa izinto zokugcoba (ezifana namafutha amaminerali kanye nama-ester okwenziwa) phakathi kwe-rolls kanye ne-i-foil yethusiNoma kunjalo, le nqubo iholela ekugcinweni kwamafutha ngezindlela ezimbili eziyinhloko:

• Ukumuncwa komhlaba: Ngaphansi kwengcindezi yokugoqa, ifilimu kawoyela ye-micron-scale (ubukhulu obungu-0.1-0.5μm) inamathela ebusweni be-foil yethusi.
• Ukungena kwangaphakathi: Ngesikhathi sokuguqulwa kwe-rolling, i-lattice yethusi ithuthukisa amaphutha amancane kakhulu (njengokuhlukana kanye nokungabi nalutho), okuvumela ama-molecule wamafutha (amaketanga e-hydrocarbon e-C12-C18) ukuthi angene ku-foil ngesenzo se-capillary, afinyelele ekujuleni okungu-1-3μm.

1.2 Imikhawulo Yezindlela Zokuhlanza Zendabuko

Izindlela zokuhlanza ubuso ezivamile (isb., ukuwasha nge-alkaline, ukusula ngotshwala) kususa kuphela amafilimu kawoyela wobuso, okufinyelela izinga lokususa elingaba ngu-70-85%, kodwa awasebenzi kahle ngokumelene namafutha amuncwa ngaphakathi. Imininingwane yokuhlola ikhombisa ukuthi ngaphandle kokususa amafutha ngokujulile, amafutha angaphakathi aphinde avele ebusweni ngemvaImizuzu engama-30 ku-150°C, ngesilinganiso sokubuyiselwa kabusha kwe-0.8-1.2g/m², okubangela "ukungcola kwesibili."

1.3 Ukuthuthukiswa Kobuchwepheshe Ekususeni Amafutha Ngokujulile

I-CIVEN METAL isebenzisa i-"Ukukhishwa kwamakhemikhali + ukusebenza kwe-ultrasonic"inqubo ehlanganisiwe:

1. Ukukhishwa kwamakhemikhali: I-ejenti ye-chelating eyenziwe ngokwezifiso (pH 9.5-10.5) ibola ama-molecule wamafutha anochungechunge olude, yakha ama-complex ancibilikayo emanzini.
2. Usizo lwe-Ultrasonic: I-ultrasound ephezulu ye-40kHz ikhiqiza imiphumela ye-cavitation, iphula amandla okubopha phakathi kwamafutha angaphakathi kanye ne-lattice yethusi, ithuthukisa ukusebenza kahle kokuqedwa kwamafutha.
3. Ukomisa nge-vacuum: Ukuphelelwa amanzi ngokushesha ku--0.08MPa umfutho ongemuhle kuvimbela ukubola.

Le nqubo inciphisa insalela yamafutha ibe≤5mg/m²(kuhlangatshezwane nezindinganiso ze-IPC-4562 ezingu-≤15mg/m²), kufezwaUkusebenza kahle kokususa okungu->99%ukuze kufakwe amafutha ngaphakathi.

2. Umthelela Oqondile Wokwelashwa Kokususa Amafutha Ezinqubweni Zokumboza Nezokushisa

2.1 Ukuthuthukiswa Kokunamathela Ezicelweni Zokumboza

Izinto zokumboza (njengezinamathiseli ze-PI kanye nama-photoresist) kumele zakhe izibopho zezinga lama-molecule ngei-foil yethusiAmafutha asele aholela ezinkingeni ezilandelayo:

• Amandla okuxhumana ancishisiwe: Ukungangeni kwamanzi kwamafutha kwandisa i-engeli yokuxhumana kwezixazululo zokumboza kusuka15° kuya ku-45°, okuvimbela ukumanzisa.
• Ukubopha kwamakhemikhali okuvinjelwe: Ungqimba lwamafutha luvimba amaqembu e-hydroxyl (-OH) ebusweni bethusi, luvimbela ukusabela kwamaqembu asebenzayo e-resin.

Ukuqhathaniswa Kokusebenza Kwe-Degreed Foil vs. I-Copper Foil Ejwayelekile:

2.2 Ukwethenjelwa Okuthuthukisiwe ku-Thermal Lamination

Ngesikhathi sokushisa okuphezulu (180-220°C), amafutha asele ku-foil yethusi evamile aholela ekuhlulekeni okuningi:

• Ukwakheka kwebhamuza: Amafutha afakwe umswakama adalaAmabhamuza angu-10-50μm(ubuningi >50/cm²).
• Ukwehlukaniswa kwezingqimba phakathi: Amafutha anciphisa amandla e-van der Waals phakathi kwe-epoxy resin ne-copper foil, okunciphisa amandla e-peel ngokunciphisa30-40%.
• Ukulahlekelwa yi-dielectric: Igrisi yamahhala ibangela ukuguquguquka okungaguquki kwe-dielectric (ukwehluka kwe-Dk >0.2).

NgemvaAmahora ayi-1000 okuguga kwe-RH okungu-85°C/85%, Insimbi EcwebezelayoI-Copper Foilimibukiso:

• Ukuminyana kwebhamuza: <5/cm² (isilinganiso semboni >30/cm²).
• Amandla okuxebuka: Igcina1.6N/cm(inani lokuqala1.8N/cm, izinga lokuwohloka liyi-11% kuphela.
• Ukuqina kwe-dielectric: Ukwehluka kwe-Dk ≤0.05, umhlanganoIzidingo zemvamisa yamagagasi angamamilimitha angu-5G.

3. Isimo Semboni kanye Nesikhundla Sokulinganisa se-CIVEN METAL

3.1 Izinselele Zemboni: Ukwenza Inqubo Ibe Lula Ngokusebenzisa Izindleko

KuphelileAbakhiqizi be-foil yethusi egoqiwe abangu-90%ukwenza kube lula ukucubungula ukuze kuncishiswe izindleko, kulandela indlela yokusebenza eyisisekelo:

Ukugoqa → Ukuwasha Ngamanzi (isisombululo se-Na₂CO₃) → Ukomisa → Ukugoqa

Le ndlela isusa amafutha angaphezulu kuphela, ngokushintshashintsha kokumelana nobuso ngemva kokugezwa±15%(Inqubo ye-CIVEN METAL iqhubeka ngaphakathi±3%).

3.2 Uhlelo Lokulawula Ikhwalithi “olungenasici” lwe-CIVEN METAL

• Ukuqapha ku-inthanethi: Ukuhlaziywa kwe-X-ray fluorescence (XRF) kokuthola izinto ezisele ebusweni ngesikhathi sangempela (S, Cl, njll.).
• Ukuhlolwa kokuguga okusheshayo: Ukulingisa ngokweqile200°C/amahora angama-24izimo zokuqinisekisa ukuthi amafutha awaphinde avele.
• Ukulandelelwa kwenqubo egcwele: Umqulu ngamunye uhlanganisa ikhodi ye-QR exhumanisa neAmapharamitha angu-32 enqubo ebalulekile(isib. izinga lokushisa lokususa amafutha, amandla e-ultrasonic).

4. Isiphetho: Ukwelashwa Kokususa Amafutha—Isisekelo Sokukhiqiza Izinto Zogesi Ezisezingeni Eliphezulu

Ukwelashwa okujulile kwe-foil yethusi egoqiwe akuyona nje indlela yokuthuthukisa inqubo kodwa kuyindlela yokucabanga kusengaphambili ukuze kusetshenziswe esikhathini esizayo. Ubuchwepheshe obuthuthukisiwe be-CIVEN METAL buthuthukisa ukuhlanzeka kwe-foil yethusi kuze kube sezingeni le-athomu, okunikezaisiqinisekiso sezinga lezinto ezibonakalayongobaukuxhumana okunobuningi obuphezulu (i-HDI), izifunda eziguquguqukayo zezimoto, kanye neminye imikhakha esezingeni eliphezulu.

Ku-Isikhathi se-5G kanye ne-AIoT, izinkampani kuphela ezikwaziyo ubucikoubuchwepheshe bokuhlanza obuyinhlokokungathuthukisa izinto ezintsha zesikhathi esizayo embonini ye-foil yethusi kagesi.
