Ukwelashwa Kwe-Degreasing Kwe-Rolled Copper Foil: Inqubo Eyinhloko kanye Nesiqinisekiso Esiyinhloko Sokumboza kanye Nokusebenza Kwe-Thermal Lamination

I-foil yethusi egoqwekuyinto ewumnyombo embonini yesekethe ye-elekthronikhi, futhi ukuhlanzeka kwayo kwangaphakathi nangaphakathi kunquma ngokuqondile ukwethembeka kwezinqubo ezansi nomfula njengokumboza kanye ne-thermal lamination. Lesi sihloko sihlaziya indlela yokwelapha yokwehlisa amafutha okuthuthukisa ukusebenza kwefoyili yethusi egoqiwe kusukela ekubukeni kokubili kokukhiqiza nokusetshenziswa. Isebenzisa idatha yangempela, ibonisa ukuguquguquka kwayo ezimweni zokucubungula izinga lokushisa eliphezulu. I-CIVEN METAL isungule inqubo yobunikazi ejulile yokwehlisa amafutha ephula izingqinamba zemboni, inikeze izixazululo ezinokwethenjelwa okuphezulu kwe-copper foil yokukhiqiza okuphezulu kwe-elekthronikhi.

1. Umnyombo Wenqubo Yokuwohloka: Ukususwa Okukabili Kobuso kanye Negrisi Yangaphakathi

1.1 Izingqinamba Zamafutha Ezinsalela Enqubweni Yokugoqa

Ngesikhathi sokukhiqizwa kwe-foil yethusi egoqiwe, ama-ingots ethusi athatha izinyathelo eziningi zokugoqa ukuze enze izinto ze-foil. Ukunciphisa ukushisa okungqubuzanayo nokuguga, izinto zokugcoba (njengamafutha amaminerali nama-synthetic esters) asetshenziswa phakathi kwamaroli kanyeucwecwe lwethusiphezulu. Kodwa-ke, le nqubo iholela ekugcinweni kwamafutha ngezindlela ezimbili eziyinhloko:

• Ukukhangisa kobuso: Ngaphansi kwengcindezi eginqikayo, ifilimu kawoyela esikalini esincane (ugqinsi okungu-0.1-0.5μm) inamathela endaweni engaphezulu ye-copper.
• Ukungena kwangaphakathi: Ngesikhathi sokuguqulwa kwe-rolling, i-lattice yethusi idala iziphambeko ezincane (ezifana nokuhlukaniswa kanye ne-voids), okuvumela ama-molecule wamafutha (amaketanga e-hydrocarbon e-C12-C18) ukuthi angene ku-foil ngesenzo se-capillary, afinyelele ekujuleni kwe-1-3μm.

1.2 Imikhawulo Yezindlela Zokuhlanza Zendabuko

Izindlela ezijwayelekile zokuhlanza indawo (isb., ukugeza i-alkaline, ukusula utshwala) susa amafilimu kawoyela angaphezulu kuphela, kufinyelelwe izinga lokususa cishe70-85%, kodwa awasebenzi ngokumelene namafutha amunca ngaphakathi. Idatha yokuhlola ibonisa ukuthi ngaphandle kokuwohloka okujulile, amafutha angaphakathi aphinde avele phezulu ngemva kwalokhoBhaka ku-150 ° C imizuzu engu-30, ngenani lokubuyisela kabusha le0.8-1.2g/m², okubangela “ukungcola okwesibili.”

1.3 Ukuthuthuka Kwezobuchwepheshe Ekunciphiseni Okujulile

I-CIVEN METAL isebenzisa i-a"i-chemical extraction + activation ultrasonic"inqubo eyinhlanganisela:

1. Ukukhishwa kwamakhemikhali: I-ejenti ye-chelating yangokwezifiso (pH 9.5-10.5) ibolisa ama-molecule e-long-chain grease, yenze izinkimbinkimbi ezincibilika emanzini.
2. Usizo lwe-ultrasonic: I-40kHz i-high-frequency ultrasound 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 emzimbeni okusheshayo ku--0.08MPa ukucindezela okungalungile kuvimbela i-oxidation.

Le nqubo inciphisa izinsalela zamafutha≤5mg/m²(ihlangabezana namazinga e-IPC-4562 we-≤15mg/m²), ukufeza> 99% ukususa ukusebenza kahlekugrisi amuncwa ngaphakathi.

2. Umthelela Oqondile Womuthi Wokuwohloka Kuma-Coating and Thermal Lamination Processes

2.1 Ukuthuthukiswa Kokunamathela Ezicelweni Zokunamathela

Izinto zokumboza (njengezinto zokunamathisela ze-PI kanye nama-photoresist) kufanele zakhe amabhondi eleveli yamangqamuzanaucwecwe lwethusi. Amafutha asele aholela ezinkingeni ezilandelayo:

• Amandla aphakathi kobuso ancishisiwe: I-hydrophobicity yamafutha inyusa i-engeli yokuxhumana yezixazululo zokumboza ukusuka15° kuya ku-45°, avimbe ukuchama.
• Ukuhlanganiswa kwamakhemikhali okuvinjelwe: Isendlalelo samafutha sivimba amaqembu e-hydroxyl (-OH) endaweni yethusi, ivimbela ukusabela ngamaqembu asebenzayo we-resin.

Ukuqhathaniswa kokusebenza kwe-Degreased vs. I-Copper Evamile:

2.2 Ukwethenjwa Okuthuthukisiwe Ku-Thermal Lamination

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

• Ukwakheka kwebhamuza: Amafutha afakwe umphunga adala10-50μm amagwebu(ukuminyana >50/cm²).
• I-Interlayer delamination: Ukugcoba kunciphisa amandla e-van der Waals phakathi kwe-epoxy resin ne-copper foil, kunciphisa amandla e-peel ngo30-40%.
• Ukulahlekelwa kwe-Dielectric: Igrisi yamahhala ibangela ukuguquguquka okungaguquki kwe-dielectric (i-Dk variation>0.2).

NgemvaAmahora angu-1000 we-85°C/85% ukuguga kwe-RH, CIVEN METALI-Copper Foilimibukiso:

• Ukuminyana kwebhamuza: <5/cm² (isilinganiso semboni >30/cm²).
• Amandla e-peel: Iyalondoloza1.6N/cm(inani lokuqala1.8N/cm, izinga lokuwohloka lingu-11% kuphela.
• Ukuzinza kwe-Dielectric: Ukuhluka kuka-Dkt ≤0.05, umhlanganoIzidingo ze-5G millimeter-wave frequency.

3. Isimo Semboni kanye Nesikhundla Sokuqhathanisa se-CIVEN METAL

3.1 Izinselelo Zemboni: Inqubo Eqhutshwa Izindleko Ukwenza Lula

KuphelileI-90% yabakhiqizi be-foil yethusi egoqiweukwenza kube lula ukucubungula ukuze kuncishiswe izindleko, ngokulandela ukuhamba komsebenzi okuyisisekelo:

Ukugoqa → Ukugeza Amanzi (Isixazululo se-Na₂CO₃) → Ukomisa → Ukusonga

Le ndlela isusa amafutha angaphezulu kuphela, ngokuguquguquka kwe-post-wash surface resistivity of±15%(Inqubo ye-CIVEN METAL igcinwa ngaphakathi±3%).

3.2 Uhlelo lwe-CIVEN METAL “Zero-Defect” Lokulawula Ikhwalithi

• Ukuqapha ku-inthanethi: Ukuhlaziywa kwe-X-ray fluorescence (XRF) ukuze kutholwe ngesikhathi sangempela izinto ezisele ezingaphezulu (S, Cl, njll.).
• Ukuhlolwa kokuguga okusheshisiwe: Ukulingisa ngokwedlulele200°C/24hizimo zokuqinisekisa ukuthi i-zero grease iyavela kabusha.
• Ukulandeleka kwenqubo ephelele: Umqulu ngamunye uhlanganisa ikhodi ye-QR exhunywe kuyo32 key process izinhlaka(isb., izinga lokushisa elinciphayo, amandla e-ultrasonic).

4. Isiphetho: Ukwelapha Ukwehlisa Isisindo-Isisekelo Sokukhiqiza Okuphezulu Kwe-Electronics

Ukwelashwa kokwehlisa amafutha okujulile kwefoyili yethusi egoqiwe akuyona nje ukuthuthukiswa kwenqubo kodwa ukuzivumelanisa nokucabanga okuya phambili kuzicelo zesikhathi esizayo. Ubuchwepheshe obuphumelelayo be-CIVEN METAL buthuthukisa ukuhlanzeka kwe-copper foil ezingeni le-athomu, ukuhlinzekaisiqiniseko sezinga lempahlaokwehigh-density interconnects (HDI), izifunda eziguquguqukayo zezimoto, nezinye izinkambu ezisezingeni eliphezulu.

KweIsikhathi se-5G ne-AIoT, izinkampani kuphela ezisebenza kahlecore yokuhlanza technologiesingaqhuba izinto ezintsha zesikhathi esizayo embonini ye-electronic copper foil.
