Iibhodi zesekethe eziprintiweyo eziguquguqukayo luhlobo olugobekayo lwebhodi yesekethe eyenziwe ngezizathu ezininzi. Izibonelelo zayo kwiibhodi zesekethe zemveli ziquka ukuncipha kweempazamo zendibano, ukomelela ngakumbi kwiimeko ezirhabaxa, kunye nokukwazi ukuphatha ulungelelwaniso oluntsonkothileyo lwe-elektroniki. Ezi bhodi zeesekethe zenziwa ngokusebenzisa i-electrolytic copper foil, into ebonakalayo ngokukhawuleza ukuba yenye yezona zinto zibalulekileyo kumashishini ombane kunye nonxibelelwano.

Zenziwa njani iiSekethe zeFlex

Iisekethe zeFlex zisetyenziswa kwi-elektroniki ngenxa yezizathu ezahlukeneyo. Njengoko bekutshiwo ngaphambili, inciphisa iimpazamo zendibano, iyakwazi ukumelana nokusingqongileyo, kwaye inokuphatha izinto zombane ezinzima. Nangona kunjalo, inokunciphisa iindleko zabasebenzi, inciphise ubunzima kunye neemfuno zendawo, kwaye inciphise iindawo zoqhagamshelwano ezinyusa uzinzo. Kuzo zonke ezi zizathu, iisekethe eziguqukayo yenye yezona ndawo zifunwa kakhulu ze-elektroniki kwishishini.

A isekethe eprintiweyo eguqukayoyenziwe ngamacandelo amathathu aphambili: Ii-Conductors, i-Adhesives, kunye ne-Insulators. Ngokuxhomekeke kwisakhiwo seesekethe eziguquguqukayo, ezi zixhobo zintathu zilungiselelwe ukuba zihambe ngoku ngendlela efunwa ngumthengi, kunye nokuba idibane namanye amacandelo e-elektroniki. Eyona nto ixhaphakileyo yokuncamathelisa kwesekethe ye-flex yi-epoxy, i-acrylic, i-PSAs, okanye ngamanye amaxesha akukho nanye, ngelixa i-insulators ezisetyenziswa ngokuqhelekileyo ziquka i-polyester kunye ne-polyamide. Okwangoku, sinomdla kakhulu kubaqhubi abasetyenziswa kwezi ziphaluka.

Ngelixa ezinye izinto ezifana nesilivere, ikhabhoni, kunye ne-aluminiyam zingasetyenziswa, eyona nto ixhaphakileyo kubaqhubi lubhedu. I-foil yobhedu ithathwa njengento ebalulekileyo yokwenziwa kweesekethe eziguqukayo, kwaye iveliswa ngeendlela ezimbini: i-rolling annealing okanye i-electrolysis.

IiFoil zeCopper zenziwe njani

Ifoyile yobhedu eqengqelekisiweyoiveliswa ngokuqengqeleka kwamaphepha obhedu, uwacuthe kwaye enze umphezulu wobhedu ogudileyo. Amaphepha obhedu aphantsi kokushisa okuphezulu kunye noxinzelelo ngale ndlela, ukuvelisa indawo epholileyo kunye nokuphucula i-ductility, i-bendability, kunye ne-conductivity.

Okwangoku,i-electrolytic copper foil uveliswa ngokusebenzisa inkqubo electrolysis. Isisombululo sobhedu senziwe nge-asidi ye-sulfuric (kunye nezinye izongezo ezixhomekeke kwiinkcukacha zomenzi). Iseli ye-electrolytic iqhutywe ngesisombululo, nto leyo ebangela ukuba i-ion zobhedu ziqhube kwaye zihlale kumphezulu we-cathode. Izongezo zinokongezwa kwisisombululo esinokuguqula iimpawu zayo zangaphakathi kunye nokubonakala kwayo.

Le nkqubo ye-electroplating iyaqhubeka de idrum ye-cathode isuswe kwisisombululo. Igubu likwalawula ukuba ifoyile yobhedu iya kuba ngqindilili kangakanani na, njengoko igubu elijikeleza ngokukhawuleza likwatsala imvula enkulu, lijiya ifoyile.

Kungakhathaliseki ukuba yeyiphi indlela, zonke iifoyile zobhedu eziveliswe kuzo zombini ezi ndlela ziya kunyangwa ngonyango lwe-bonding, unyango lokumelana nokushisa, kunye nokuzinza (i-anti-oxidation) unyango emva koko. Ezi zonyango zenza ukuba iifoyile zobhedu zikwazi ukubopha ngcono kwi-adhesive, zikwazi ukumelana nobushushu obubandakanyekayo ekudalweni kwesekethe eprintiweyo yangempela, kunye nokuthintela i-oxidation ye-foil yobhedu.

I-Rolled Annealed vs Electrolytic

Ngenxa yokuba inkqubo yokudala i-foil yobhedu ye-rolled annealed and electrolytic copper foil yahlukile, nayo ineenzuzo ezahlukeneyo kunye nokungonakali.

Umahluko omkhulu phakathi kweefoyile ezimbini zobhedu ngokwemigaqo yesakhiwo sabo. Ifoyile yobhedu eqengqelekisiweyo iya kuba nesakhiwo esithe tyaba kwiqondo lobushushu eliqhelekileyo, elithi ke libe yi-morphs kwisakhiwo sekristale ye-lamellar xa iphantsi koxinzelelo oluphezulu kunye nobushushu. Okwangoku, i-copper ye-electrolytic foil igcina isakhiwo sayo sekholomu kumaqondo okushisa aqhelekileyo kunye noxinzelelo oluphezulu kunye namaqondo okushisa.

Oku kudala umahluko kwi-conductivity, ductility, bendability, kunye neendleko zazo zombini iintlobo zefoyile yobhedu. Ngenxa yokuba iifoyile zobhedu ezigoqiweyo ziqhelekile zigudile, ziqhuba kwaye zifaneleke ngakumbi kwiingcingo ezincinci. Zikwayi-ductile eninzi kwaye ngokubanzi zigobeka ngakumbi kunefoyile yobhedu ye-electrolytic.

Nangona kunjalo, ukulula kwendlela ye-electrolysis iqinisekisa ukuba i-electrolytic copper foil inexabiso eliphantsi kuneefoyile zobhedu eziqengqelekisiweyo. Qaphela nangona kunjalo, ukuba inokuba lukhetho olusezantsi kwimigca emincinci, kwaye banoxhathiso olubi kakhulu lokugoba kuneefoyile zobhedu eziroqiweyo.

Ukuqukumbela, iifoyile zobhedu ze-electrolytic ziyindlela efanelekileyo yexabiso eliphantsi njengabaqhubi kwisekethe eprintiweyo eguquguqukayo. Ngenxa yokubaluleka kwesekethe ye-flexible kwi-electronics nakwamanye amashishini, yona, yenza i-electrolytic copper foil ibe yinto ebalulekileyo.
