Iibhodi zesekethe eziprintiweyo eziguquguqukayo luhlobo lwebhodi yesekethe egobekayo eyenziwe ngezizathu ezahlukeneyo. Iingenelo zayo ngaphezu kweebhodi zesekethe zemveli ziquka ukunciphisa iimpazamo zokuhlanganisa, ukuqina ngakumbi kwiindawo ezinzima, kunye nokukwazi ukusingatha ulungelelwaniso oluntsonkothileyo lwe-elektroniki. Ezi bhodi zesekethe zenziwe nge-electrolytic copper foil, into ebonakala ngokukhawuleza ukuba yenye yezona zibalulekileyo kumashishini e-elektroniki kunye nonxibelelwano.

Indlela iiFlex Circuits ezenziwe ngayo

IiFlex Circuits zisetyenziswa kwi-elektroniki ngezizathu ezahlukeneyo. Njengoko bekutshiwo ngaphambili, zinciphisa iimpazamo zokuhlanganisa, ziyakwazi ukumelana nokusingqongileyo, kwaye zinokuphatha ii-elektroniki ezintsonkothileyo. Nangona kunjalo, zinokunciphisa iindleko zomsebenzi, zinciphise ubunzima kunye neemfuno zendawo, kwaye zinciphise iindawo zokunxibelelana ezinyusa uzinzo. Ngenxa yazo zonke ezi zizathu, ii-flex circuits zezinye zezona ndawo ze-elektroniki zifunwa kakhulu kushishino.

A isekethe eprintiweyo eguquguqukayoyenziwe ngamacandelo amathathu aphambili: Ii-conductors, ii-Adhesives, kunye nee-Insulators. Ngokuxhomekeke kwisakhiwo seesekethe eziguquguqukayo, ezi zinto zintathu zilungiselelwe ukuba umbane uhambe ngendlela efunwa ngumthengi, kwaye udibane nezinye izinto ze-elektroniki. Izinto eziqhelekileyo kwi-adhesive yesekethe eguquguqukayo yi-epoxy, i-acrylic, ii-PSA, okanye ngamanye amaxesha akukho, ngelixa ii-insulators ezisetyenziswa rhoqo ziquka i-polyester kunye ne-polyamide. Okwangoku, sinomdla kakhulu kwii-conductors ezisetyenziswa kwezi sekethe.

Nangona ezinye izinto ezifana nesilivere, ikhabhoni, kunye ne-aluminium zingasetyenziswa, ezona zinto zixhaphakileyo ezisetyenziselwa ii-conductors yi-copper. I-copper foil ithathwa njengezinto ezibalulekileyo ekwenzeni ii-flex circuits, kwaye iveliswa ngeendlela ezimbini: i-rolling annealing okanye i-electrolysis.

Indlela Ezenziwa Ngayo Iifoyile ZeCopper

Ifoyile yobhedu egoqiweyoiveliswa ngokuqengqa amaphepha obhedu ashushu, ukuwanciphisa aze adale umphezulu wobhedu ogudileyo. Amaphepha obhedu aphantsi kobushushu obuphezulu kunye noxinzelelo ngale ndlela, evelisa umphezulu ogudileyo kwaye iphucula ukuguguleka, ukugobeka, kunye nokuqhuba.

Okwangoku,i-electrolytic copper foiI-l iveliswa ngokusebenzisa inkqubo ye-electrolysis. Isisombululo sekopolo senziwe nge-sulfuric acid (kunye nezinye izongezo kuxhomekeke kwiinkcukacha zomenzi). Iseli ye-electrolytic emva koko iqhutywa ngesisombululo, nto leyo ebangela ukuba ii-ion zekopolo zikhawuleze zize zihlale kumphezulu we-cathode. Izongezo zingongezwa kwisisombululo esinokutshintsha iipropati zaso zangaphakathi kunye nembonakalo yaso.

Le nkqubo yokufakelwa nge-electroplating iyaqhubeka ide i-cathode drum isuswe kwisisombululo. I-drum ikwalawula ukuba i-copper foil iya kuba nkulu kangakanani, njengoko i-drum ejikelezayo ngokukhawuleza ikwatsala i-precipitate engaphezulu, iyenza i-foil ibe nkulu.

Nokuba yeyiphi na indlela, zonke iifoyile zobhedu ezenziwe kwezi ndlela zombini ziya kunyangwa ngonyango lokubopha, unyango lokumelana nobushushu, kunye nonyango lokuzinza (ukulwa ne-oxidation) emva koko. Olu nyango lwenza iifoyile zobhedu zikwazi ukubopha ngcono kwi-adhesive, zikwazi ukumelana nobushushu obubandakanyeka ekudalweni kwesekethe eprintiweyo eguquguqukayo, kwaye zithintele i-oxidation yefoyile yobhedu.

I-Rolled Annealed vs Electrolytic

Ngenxa yokuba inkqubo yokwenza i-copper foil ye-rolled annealed kunye ne-electrolytic copper foil yahlukile, zikwanazo neengenelo kunye neengxaki ezahlukeneyo.

Umahluko ophambili phakathi kwezi foyile zimbini zobhedu umalunga nolwakhiwo lwazo. I foyile yobhedu egoqwe nge-annealed iya kuba nesakhiwo esithe tyaba kubushushu obuqhelekileyo, emva koko iguquke ibe yisakhiwo sekristale ye-lamellar xa iphantsi koxinzelelo oluphezulu kunye nobushushu. Okwangoku, i foyile yobhedu ye-electrolytic igcina isakhiwo sayo sekholamu kubushushu obuqhelekileyo kunye noxinzelelo oluphezulu kunye nobushushu.

Oku kudala umahluko kwindlela eziqhuba ngayo izinto, indlela eziguquguquka ngayo izinto, indlela ezigobeka ngayo izinto, kunye nexabiso lazo zombini ezi ntlobo zefoyile yobhedu. Ngenxa yokuba iifoyile zobhedu ezigoqiweyo zihlala zithambile, ziqhuba kakuhle izinto kwaye zifanelekile kwiingcingo ezincinci. Zikwaguquguquka ngakumbi izinto kwaye zihlala ziguquguquka ngakumbi kunefoyile yobhedu ye-electrolytic.

Nangona kunjalo, ukulula kwendlela ye-electrolysis kuqinisekisa ukuba i-electrolytic copper foil inexabiso eliphantsi kune-rolled annealed copper foils. Qaphela nangona kunjalo, ukuba zinokuba lukhetho olungaphantsi kwemigca emincinci, kwaye zinokumelana okubi nokugoba kune-rolled annealed copper foils.

Ukuqukumbela, iifoyile zekopolo ze-electrolytic ziyindlela elungileyo engabizi kakhulu njengee-conductors kwisekethe eprintiweyo eguquguqukayo. Ngenxa yokubaluleka kwesekethe ye-flex kwi-elektroniki nakwamanye amashishini, nayo yenza iifoyile zekopolo ze-electrolytic zibe yinto ebalulekileyo.
