Amabhodi wesifunda aphrintiwe aguquguqukayo awuhlobo olugobekayo lwebhodi lesifunda elakhiwe ngenxa yezizathu eziningana. Izinzuzo zayo ngaphezu kwamabhodi esekethe endabuko zihlanganisa ukuncipha kwamaphutha emihlangano, ukukhuthazela kakhudlwana ezindaweni ezinokhahlo, nokukwazi ukuphatha ukucupha okuyinkimbinkimbi kagesi. Lawa mabhodi wesifunda enziwa kusetshenziswa i-electrolytic copper foil, into ebonakala ngokushesha ingenye yezinto ezibaluleke kakhulu ezimbonini ze-electronics nezokuxhumana.

Indlela Ama-Flex Circuits Enziwa Ngayo

Ama-Flex Circuits asetshenziswa ku-electronics ngezizathu ezihlukahlukene. Njengoba kushiwo ngaphambili, inciphisa amaphutha omhlangano, iyakwazi ukumelana nemvelo, futhi ikwazi ukuphatha izinto zikagesi eziyinkimbinkimbi. Kodwa-ke, kungase futhi kunciphise izindleko zabasebenzi, kwehlise isisindo kanye nezidingo zesikhala, futhi kunciphise izindawo zokuxhuma okwandisa ukuzinza. Kuzo zonke lezi zizathu, ama-flex circuits angenye yezingxenye ze-elekthronikhi ezidingeka kakhulu embonini.

A isifunda ephrintiwe nezimoyakhiwe izingxenye ezintathu eziyinhloko: Amaconductors, Adhesives, kanye nama-Insulators. Ngokuya ngesakhiwo samasekhethi aguquguqukayo, lezi zinto ezintathu zihlelelwe ukuthi zamanje zigeleze ngendlela efunwa yikhasimende, nokuthi ixhumane nezinye izingxenye ze-elekthronikhi. Izinto ezivame kakhulu zokunamathisela kwesekethe ye-flexible yi-epoxy, i-acrylic, i-PSAs, noma ngezinye izikhathi ayikho, kuyilapho ama-insulators asetshenziswa ngokuvamile afaka i-polyester ne-polyamide. Okwamanje, sibathanda kakhulu abaqhubi abasetshenziswa kulezi zifunda.

Nakuba ezinye izinto ezifana nesiliva, ikhabhoni, ne-aluminium zingasetshenziswa, izinto ezisetshenziswa kakhulu kumakhondakta yithusi. I-foil yethusi ithathwa njengento ebalulekile ekwenzeni ama-flex circuits, futhi ikhiqizwa ngezindlela ezimbili: i-rolling annealing noma i-electrolysis.

Indlela I-Copper Foil Enziwa Ngayo

I-foil yethusi egoqiweikhiqizwa ngokugingqika kwamashidi ethusi, ewanciphisa futhi enze indawo yethusi ebushelelezi. Amashidi ethusi angaphansi kwamazinga okushisa aphezulu kanye nezingcindezi ngale ndlela, ekhiqiza indawo ebushelelezi futhi athuthukise i-ductility, ukugoba, kanye ne-conductivity.

Okwamanje,i-electrolytic copper foil ikhiqizwa ngokusebenzisa inqubo electrolysis. Isixazululo sethusi senziwa nge-sulfuric acid (nezinye izithasiselo ngokuya ngemininingwane yomkhiqizi). Iseli le-electrolytic libe seligijima ngesisombululo, esibangela ukuba ama-ion ethusi ahle futhi ahlale phezu kwe-cathode. Izithasiselo zingase futhi zengezwe esixazululweni esingashintsha izici zayo zangaphakathi kanye nokubukeka kwayo.

Le nqubo ye-electroplating iyaqhubeka kuze kube yilapho isigubhu se-cathode sisuswa esixazululo. Isigubhu siphinde silawule ukuthi ifoyili yethusi izoba wugqinsi kangakanani, njengoba isigubhu esiphenduka ngokushesha siphinde sihehe imvula eningi, sijiye ucwecwe.

Kungakhathaliseki ukuthi iyiphi indlela, wonke ama-foil ethusi akhiqizwa kuzo zombili lezi zindlela zisazophathwa nge-bonding treatment, ukwelashwa kokumelana nokushisa, nokuzinza (anti-oxidation) ukwelashwa ngemva kwalokho. Lezi zindlela zokwelapha zenza ama-foil ethusi akwazi ukubopha kangcono i-adhesive, akwazi ukumelana nokushisa okuhilelekile ekudalweni kwesifunda esiphrintiwe esiguquguqukayo sangempela, futhi avimbele i-oxidation ye-foil yethusi.

I-Rolled Annealed vs Electrolytic

Ngenxa yokuthi inqubo yokudala i-foil yethusi ye-foil rolled annealed kanye ne-electrolytic copper ihlukile, futhi inezinzuzo ezahlukene kanye nokubi.

Umehluko omkhulu phakathi kwama-foil amabili ethusi ngokwesakhiwo sawo. Icwecwe lethusi eligoqiwe lizoba nesakhiwo esivundlile ekushiseni okujwayelekile, ebese sishintsha sibe yi-lamellar crystal structure uma ingaphansi kwengcindezi ephezulu kanye nezinga lokushisa. Phakathi naleso sikhathi, i-electrolytic copper foil igcina isakhiwo sayo sekholomu kuwo womabili amazinga okushisa avamile kanye nezingcindezi eziphezulu namazinga okushisa.

Lokhu kudala umehluko ku-conductivity, ductility, bendability, kanye nezindleko zazo zombili izinhlobo ze-foil yethusi. Ngenxa yokuthi ama-foil ethusi agoqiwe ngokuvamile abushelelezi, ahamba phambili futhi afaneleka kakhulu izintambo ezincane. Ziphinde zibe ama-ductile amaningi futhi ngokuvamile zigobeka kakhulu kune-electrolytic copper foil.

Nokho, ubulula bendlela ye-electrolysis buqinisekisa ukuthi ucwecwe lwethusi lwe-electrolytic lunezindleko eziphansi kunezicwecwe zethusi ezigoqiwe. Qaphela nokho, ukuthi zingase zibe inketho engaphansi kwemigqa emincane, nokuthi zinokugoba okubi kakhulu kunamaphepheli ethusi agoqiwe.

Sengiphetha, ama-foil e-electrolytic copper ayinketho enhle engabizi kakhulu njengama-conductor kusekethe ephrintiwe eguquguqukayo. Ngenxa yokubaluleka kwesekethe ye-flexible ku-electronics nakwezinye izimboni, yona, yenza ama-foil ethusi e-electrolytic abe yinto ebalulekile futhi.
