Ishidi Le-Graphite Elisebenza Ngogesi

I-Electrical Conductive Graphite Sheet iwukusebenza{0}}okuphezulu kokusebenza okuhlanganisa ukusebenza kahle nokuvumelana nezimo. Yenziwe -ngokuhlanzeka okuphezulu kwe-graphite yemvelo/yokwenziwa njengento eluhlaza, ngokusebenzisa{3}}izinga lokushisa eliphezulu, i-graphitization, nezinqubo zokusika ngokunemba. Inani layo eliyinhloko lisekuxazululeni amaphuzu ezinhlungu zezinto ezijwayelekile eziqinile zokuqondisa (ezifana ne-copper foil ne-aluminium foil) - ubunzima bokunamathela endaweni engajwayelekile, ukujwayele ukuphuka, kanye nobunzima kumadivayisi angasindi. Ingafinyelela ukudluliswa kwamanje okuzinzile kanye nokunqanyulwa kokushisa okuyisizayo kuzimo zohlelo lokusebenza eziyingcingo, ezigobile, noma eziguqukayo, futhi isebenza njengento eyinhloko esekelayo{7}}ekuxhunyweni kukagesi okuthembeke kakhulu kuma-electronics wesimanje nezinkambu zamandla amasha.

Qaphela: Umkhiqizo usekela ukwenza ngokwezifiso

1. I-Conductivity enhle kakhulu

I-resistivity yevolumu ingu-10-50 μΩ·cm (ihlolwe ku-25℃kanye no-5 MPa pressure), futhi ukuqhuba kwayo kusondele ku-80% we-foil yethusi (1.72 μΩ·cm), kuyilapho igwema izinkinga ze-oxidation kalula nokugqwala kwezinto zensimbi. Ukufana kokusatshalaliswa kwamanje okusendizeni Kukhulu noma kulingana nama-95%, okunganciphisa ngempumelelo ukugxiliswa kwendawo kwamanje futhi kuvimbele ukutubeka kwengxenye.

2. Ukuguquguquka okuhle kakhulu nokuvumelana

Kumashidi anogqinsi Olungaphansi noma olulingana no-0.2 mm, irediyasi encane yokugoba ingafinyelela ku-5-10 mm, futhi ukugoba okuphindaphindiwe ngeke kubangele ukuqhekeka noma ukuwohloka kwe-conductivity. Ingakwazi ukunamathela ngokuqinile ezindaweni ezingajwayelekile (njengamaphethelo eseli kanye nezakhiwo zokupakisha ze-chip) futhi igcwalise izikhala ezincane ( Ngaphansi noma okulingana no-0.1 mm), iqinisekise ukuthintana kukagesi okuqhubekayo ngisho nasezindaweni ezidlidlizayo.

3.Umsebenzi Ombaxambili Wokuqhuba Nokukhipha Ukushisa

Ngenkathi ihambisa ugesi, ine- -i-thermal conductivity yendiza engu-150-400 W/(m·K), engadlulisa ngokuhambisanayo ukushisa okukhiqizwa izingxenye ze-elekthronikhi (njengama-chips namabhethri) ezingxenyeni ezikhipha ukushisa. Uma kuqhathaniswa nezinto zokwenziwa ezisebenza kanyekanye, kunganciphisa inani lezendlalelo zempahla ngaphakathi kwedivayisi ngaphezu kuka-30%, konga isikhala sangaphakathi.

4. Ukuzivumelanisa Nemvelo Okuqinile

Ibanga lezinga lokushisa elisebenzayo lingu--60~200℃, futhi lisengakwazi ukulondoloza ukusebenza okuzinzile (ukushintsha kokumelana Nezinga eliphansi noma elilingana no-10%)-ezindaweni zokushisa eziphansi, eziphansi, noma ezinomswakama (30% -95% umswakama ohlobene no-40℃). Imelana nama-asidi abuthakathaka nama-alkali (pH 4-9) futhi ayisebenzi ngezinto ezivamile zokupakisha ze-elekthronikhi (njenge-epoxy resin ne-silicone).

5. Ayihambisani Nemvelo futhi Kulula Ukuyicubungula

Amashidi e-graphite aqhutshwayo enziwe-nge-graphite emsulwa ephezulu enobumsulwa obungaphezu kuka-99.9%, angenazo izinsimbi ezisindayo njengomthofu, i-mercury, i-cadmium, njll., futhi athobelana ne-RoHS 2.0 kanye ne-REACH namazinga emvelo. Ingenziwa ngendlela oyifisayo ibe amafomu ahlukahlukene njengeshidi, i-strip, izingxenye ze-die cut, njll. ngokusebenzisa izinqubo zokusika ne-stamping laser, ngokunemba kokucubungula okungu-± 0.05 mm.

1. Ukubhekana nezinhlungu ezinokwethenjelwa 'zokuxhumana okuguquguqukayo'

• Iphuzu lobuhlungu: Izinsalela zensimbi zendabuko (ezifana ne-copper foil) zivame ukuphuka ukukhathala kanye nokwehluleka kwe-conductivity ezindaweni ezidinga ukugoba okuphindaphindiwe, njengamahinge esikrini sokugoqa kanye nezintambo ze-FPC; I-conductive adhesive ibeka engcupheni yokuguga.
• Isixazululo: Ngokusebenzisa ukuguquguquka kwemvelo kwe-graphite, ingakwazi ukumelana namashumi ezinkulungwane zokugoba ngaphandle kokuqhekeka, ixazulula inkinga "yezinto eziqinile eziphuka ezakhiweni ezinamandla".

2.Ikhuluma nge-Electromagnetic Shielding (EMI) ngaphansi kwe-"Space Limits"

• Amaphuzu obuhlungu: Isikhala sangaphakathi samafoni e-5G nemishini egqokekayo sibaluleke kakhulu, futhi izihlangu zensimbi zendabuko (I-Metal Can) ziwugqinsi kakhulu futhi kunzima ukuzuza ukumbozwa okugcwele ezindaweni ezigobile noma ezikhaleni eziwumngcingo.
• Isixazululo: Ngobukhulu bokugcina obungu-0.03-0.1mm, ingasetshenziswa njengesendlalelo esivikelayo ukuze inamathele ebusweni bama-chips noma amamojula, futhi ingakwazi ukumunca ngempumelelo ukuphazamiseka kazibuthe ngokusebenzisa ukuhanjiswa okuphezulu (ukumelana nobuso<1 Ω/□), solving the contradiction of "both shielding and lightweight".

3. Xazulula "i-static accumulation" kanye nesisekelo esingesihle

• Amaphuzu obuhlungu: Izikrini ze-LCD/OLED nezikrini zokuthinta zijwayele ukunqwabelana kagesi omile (ESD) emaphethelweni, okungabangela ukuphuka kwe-IC yomshayeli uma iphansi kahle; othintana nabo bendabuko bentwasahlobo yensimbi banendawo encane yokuxhumana futhi bathambekele ekungeneni kwe-oxidation, okuholela ekukhuphukeni kwe-impedance.
• Isixazululo: Nikeza indawo enkulu yomzila wokumisa umfaniswano nge-resistivity ephansi futhi ezinzile, engakhipha ngokushesha ugesi omile futhi ixazulule inkinga "yokuthintana kwephuzu elingathembeki".

4. Ukubhekana nezidingo zokuhlanganisa "zokushisa kokushisa kanye ne-conductivity"

• Iphoyinti lobuhlungu: Amanye amadivaysi amandla (njengama-amplifiers) adinga kokubili ukuchithwa kokushisa kanye nokusebenza. Ukusebenzisa amashidi ensimbi ye-thermal conductivity kuyasinda, kuyilapho ukusebenzisa amashidi aphethwe yi-thermal conductive akukwazi ukuqhuba ugesi.
• Isixazululo: Ukusetshenziswa kabili kwempahla eyodwa. Nakuba inikeza okuhle kakhulu{1}ekusakazeni kokushisa kwendiza, igcina ukusebenza okuphezulu futhi ithatha indawo yesakhiwo esiyinkimbinkimbi se-"metal heat sink+conductive adhesive", yehlisa izindleko ze-BOM nobunzima bokuhlanganisa.

5. Ukubhekana nokuvalwa kwe-conductive ezindaweni zokugqwala kwamakhemikhali

• Iphuzu lobuhlungu: Amapuleti e-Fuel cell bipolar kanye nezinzwa zamakhemikhali zijwayele ukugqwala abaqoqi bamanje bensimbi ezindaweni ezine-acidic/alkaline, okuholela ekuqubukeni kokumelana nokuxhumana.
• Isixazululo: Ukungangeni kwamakhemikhali kwegraphite kugcina ukusebenza kahle kwemithombo yezindaba ebolayo, kuxazululwa inkinga "yokwehluleka ukugqwala kwe-electrochemical" kwezinto zensimbi.

• Le nkampani iphumelele uhlelo lokuphathwa kwekhwalithi ye-ISO9001 kanye nesitifiketi se-ISO14001 sokuphathwa kwemvelo, ekhombisa ukuphishekela kwayo okuvelele ekulawuleni ikhwalithi kanye nokukhiqizwa okulungele imvelo. Sinobuchwepheshe obunelungelo lobunikazi obuyi-9 obuhlanganisa izindawo ezibalulekile njengenqubo yokulungiselela impahla ye-graphite kanye nokwenza kahle komkhiqizo, okuhlinzeka ngokusekela okuqinile kokuncintisana komkhiqizo wenkampani.

Asibona abakhiqizi kuphela, kodwa futhi abahlinzeki bezixazululo eziphelele, sithuthukisa imiklamo ngokusekelwe ezicini zezimboni zendabuko ukuze kuzuzwe ukukhiqizwa kwezimboni okuphelele.

• Isiqinisekiso Sesevisi

1. Ukulawulwa kwenqubo: Ukunemba kokugingqika ± 0.01mm, iphutha lokusika Ngaphansi noma elilingana no-0.5mm, kuqinisekisa ukunemba okuphezulu komkhiqizo. Imishini yokukhiqiza ethuthukisiwe kanye nezinhlelo zokulawula ezizenzakalelayo zisetshenziselwa ukuzuza ukulawulwa okunembile kwezinqubo zokukhiqiza

2. Ukuphatha okuhlukile: Sungula indlela yokuhlaziya i-Root Cause Analysis (RCA) yamahora angu-4 ukuze uphendule ngokushesha ezindabeni zekhwalithi futhi uthathe izinyathelo zokulungisa ngesikhathi. Rekhoda futhi uhlaziye izimo ezingajwayelekile ngokuningiliziwe, fingqa izifundo ozitholile, futhi uvimbele izinkinga ezifanayo ukuthi ziphinde zenzeke.

3. Ukuthuthukiswa okuqhubekayo: Izinga lesikhalazo samakhasimende ngonyaka lingaphansi kuka-0.3%. Ngempendulo yamakhasimende, siqhubeka sithuthukisa ikhwalithi yomkhiqizo namazinga wesevisi, njalo senza imisebenzi yokuthuthukisa ikhwalithi, sithuthukisa izinqubo zokukhiqiza, futhi sithuthukisa ukusebenza komkhiqizo nokuzinza kwekhwalithi.

Amashadi ashisayo: ishidi le-graphite elisebenza ngogesi, abakhiqizi beshidi le-graphite abaqhuba ngogesi
