Kweli nqaku, siza kujonga ngakumbi kwizinto eziqhelekileyo ezisetyenziswa kwiukuveliswa kwesekethe eprintiweyo eguquguqukayo.

Iisekethe eziprintiweyo eziguquguqukayo (FPC) zitshintshe kakhulu icandelo le-elektroniki. Ukukwazi kwabo ukugoba kubenza badume kumashishini ahlukeneyo abandakanya i-aerospace, izithuthi, ukhathalelo lwempilo, kunye nombane wabathengi.

Enye yezinto eziphambili ezisetyenziselwa ukuveliswa kweesekethe eziprintiweyo eziguquguqukayo yi-polyimide.I-Polyimide yipolymer esebenza kakhulu enozinzo oluhle kakhulu lwe-thermal, ukumelana neekhemikhali kunye nokuqina koomatshini. Ezi zakhiwo zenza ukuba zilungele iisekethe eziguquguqukayo njengoko zikwazi ukumelana nokushisa okuphezulu kunye neendawo ezinzima ngaphandle kokuchaphazela ukusebenza kwayo. Iifilimu ezisekelwe kwi-Polyimide ziqhele ukusetyenziswa njenge-substrates kwiisekethe eziprintiweyo eziguquguqukayo.

Ukongeza kwi-polyimide, enye into ehlala isetyenziswa kwimveliso yesekethe eguquguqukayo yobhedu.I-Copper yakhethwa ngenxa yombane wayo obalaseleyo, ukuxhathisa ukubola kunye ne-ductility. Ifoyile yobhedu ebhityileyo idla ngokulanywa kwi-polyimide substrate ukwenza indlela yokuqhuba yesekethe. Uluhlu lobhedu lubonelela ngoqhagamshelwano oluyimfuneko lombane olufunekayo ukuze isekethe isebenze ngokufanelekileyo.

Ukukhusela umkhondo wobhedu kunye nokuqinisekisa ixesha elide lesekethe eprintiweyo eguquguqukayo, i-cover cover okanye imaski ye-solder iyadingeka.Ukwaleka yifilimu encamathelayo ye-thermoset edla ngokusetyenziswa kwiindawo zesekethe. Isebenza njengomaleko okhuselayo, ukukhusela umkhondo wobhedu kwizinto ezisingqongileyo ezifana nokufuma, uthuli kunye nomonakalo womzimba. Impahla yokugubungela ngokuqhelekileyo ifilimu esekelwe kwi-polyimide, enegunya eliphezulu lokubopha kwaye inokudibaniswa ngokuqinileyo kwi-polyimide substrate.

Ukwandisa ngakumbi ukuqina kunye nokusebenza kweesekethe eziguquguqukayo eziprintiweyo, izinto zokuqinisa ezifana ne-tape okanye izinto zokuqinisa zihlala zisetyenziswa.Yongeza ukuqiniswa kwiindawo ezithile zesekethe apho kufuneka amandla angaphezulu okanye ukuqina. Ezi zixhobo zinokubandakanya iindlela ezahlukeneyo zokukhetha, ezifana ne-polyimide okanye ifilimu ye-polyester, i-fiberglass, okanye i-metal foil. Ukuqiniswa kunceda ukukhusela iisekethe ukuba zingakrazuli okanye ziqhekeze ngexesha lokunyakaza okanye ukusebenza.

Ukongezelela, iipads okanye oonxibelelwano zongezwa ukwenzela ukuba kube lula ukudibanisa phakathi kwesekethe eprintiweyo eguquguqukayo kunye nezinye izinto ze-elektroniki.Ezi pads ziqhele ukwenziwa ngokudityaniswa kobhedu kunye nezinto ezikwaziyo ukumelana ne-solder. Iipads zokudibanisa zibonelela nge-interface efunekayo yokudibanisa okanye ukudibanisa amacandelo afana neesekethe ezidibeneyo (ICs), i-resistors, i-capacitors, kunye nezixhumi.

Ukongeza kwizinto ezingundoqo ezingasentla, ezinye izinto zingongezwa ngexesha lenkqubo yokuvelisa ngokuxhomekeke kwiimfuno ezithile.Ngokomzekelo, i-adhesives ingasetyenziselwa ukudibanisa iindidi ezahlukeneyo zeesekethe eziprintiweyo kunye. Ezi zibophelelo ziqinisekisa ibhondi eyomeleleyo kwaye ethembekileyo, evumela ukuba isiphaluka sigcine ingqibelelo yesakhiwo. Izincamathelisi zeSilicone zihlala zisetyenziswa ngenxa yokuguquguquka kwazo, ukumelana nobushushu obuphezulu, kunye neempawu ezibalaseleyo zokubopha.

Ngokubanzi, izinto ezisetyenziselwa ukuveliswa kweesekethe eziprintiweyo eziguquguqukayo zikhethwe ngokucophelela ukuqinisekisa ukusebenza kakuhle kunye nokuqina.Ukudibanisa i-polyimide njenge-substrate, ubhedu be-conductivity, ukugqithiswa kokukhusela, izinto zokuqinisa amandla okongeziweyo, kunye neepads zokudityaniswa kwecandelo zenza isekethe eprintiweyo ethembekileyo nesebenza ngokupheleleyo. Ukukwazi kwezi sekethe ukuziqhelanisa neentlobo ngeentlobo zezicelo, kubandakanywa indawo egobileyo kunye neendawo ezixineneyo, kuzenza zibe yimfuneko kwizixhobo zombane zanamhlanje.

Isishwankathelo, izixhobo zesekethe eziguquguqukayo eziprintiweyo ezifana ne-polyimide, ubhedu, ukugqithiswa, ukuqiniswa, ukunamathela, kunye neepads zizinto eziphambili ekudaleni iisekethe ze-elektroniki ezihlala zihleli kwaye ziguquguqukayo.Ezi zixhobo zisebenza kunye ukubonelela ukudibanisa okufunekayo kombane, ukukhuselwa kunye namandla omatshini afunekayo kwizixhobo zombane zanamhlanje. Njengoko itekhnoloji iqhubeka nokuvela, imathiriyeli esetyenziswa kwimveliso yesekethe eguquguqukayo eprintwayo kunokwenzeka ukuba iguquke ngakumbi, ivumela usetyenziso oluninzi.
