Isingeniso Somkhiqizo

I-Flexible Circuit Board (FPC), eyaziwa nangokuthi ibhodi yesekethe eliguquguqukayo, ibhodi yesekethe eliguqukayo, isisindo sayo esikhanyayo, ukuqina okuncane, ukugoqa kwamahhala nokugoqwa nezinye izici ezinhle kanye nezinye izici ezinhle nakwezinye izici ezinhle. Kodwa-ke, ukuhlolwa kwekhwalithi yasekhaya ye-FPC ikakhulukazi kuncike ekuhlolweni okubonakalayo kwe-Manual, okuyindleko ephezulu kanye nokusebenza kahle okuphansi. Ngokuthuthuka okusheshayo komkhakha we-elekthronikhi, ukwakheka kwebhodi lesekethe okuphezulu nokunemba okuphezulu kakhulu, kanye nendlela yokutholwa kwencwadi yendabuko ngeke isakwazi ukuhlangabezana nezidingo zokukhiqiza, nokutholwa okuzenzakalelayo kwe-FPC sekuphenduke umkhuba wokuthuthuka kwezimboni.

I-Flexible Circuit (FPC) ubuchwepheshe obuthuthukiswe yi-United States ukuze kuthuthukiswe ubuchwepheshe be-Space Rocket ngeminyaka yo-1970. Kungumjikelezo ophrintiwe onokwethenjwa okuphezulu nokuguquguquka okuhle okwenziwe ngeFolyester Film noma i-polymide njenge-substrate. Ngokushumeka umklamo wesifunda ephepheni lepulasitiki elithambile eliguquguqukayo, inani elikhulu lezakhi ezinengqondo lifakwe endaweni emncane futhi elinqunyelwe. Ngaleyo ndlela ukwakha umjikelezo oguquguqukayo ovumelana nezimo. Lesi sifunda singagoba futhi sigoqwe ngentando, isisindo esikhanyayo, usayizi omncane, ukunqatshelwa kokushisa okuhle, ukufakwa okulula, ukwephula ubuchwepheshe bendabuko ye-interconnection. Esakhiweni somjikelezo oguquguqukayo, izinto zokwakha ziyifilimu efakwayo, umqhubi kanye ne-ejenti ebondiwe.

Impahla ye-contonent 1, ifilimu yokufakelwa

Ifilimu efaka ukufakwa kwakha isendlalelo sesisekelo sesifunda, kanye nama-adhesive Bond acler foil kwisendlalelo sokufaka. Emklamweni onobungqingili ohlukahlukene, bese uhlanganiswa ungqimba lwangaphakathi. Baphinde basetshenziswe njengesembozo esivikelekile sokufaka umjikelezo othulini kanye nomswakama, futhi banciphise ukucindezeleka ngesikhathi sokuguquguquka, i-foil yethusi yakha ungqimba olusebenzayo.

Emidlalweni ethile eguquguqukayo, izingxenye eziqinile ezakhiwa yi-aluminium noma ngensimbi engagqwali ziyasetshenziswa, ezinganikeza ukuqina kobukhulu, zinikeze ukusekelwa ngokomzimba kokubekwa kwezakhi nezintambo, nokukhipha ingcindezi. Ukunamathela kuhlanganisa ingxenye eqinile kwisekethe eguquguqukayo. Ngaphezu kwalokho, okunye okusetshenziswayo kwesinye isikhathi kusetshenziswa emibuthanweni eguqukayo, okuyinto ungqimba lokunamathela, okwakhiwa ukuhlanganisa izinhlangothi zombili zefilimu efaka ukunamathela. Ama-lamive ama-lamive ahlinzeka ngokuvikelwa kwemvelo kanye nokufakwa kwe-elekthronikhi, kanye nekhono lokuqeda ifilimu elilodwa elincane, kanye nekhono lokuhlanganisa izingqimba eziningi ngezendlalelo ezimbalwa.

Kunezinhlobo eziningi zezinto zokufaka amafilimu, kepha ezisetshenziswa kakhulu yi-polymide ne-polyester izinto. Cishe ama-80% abo bonke abakhiqizi beseketheli abasezingeni eliphakeme e-United States basebenzisa izinto zefilimu ze-polymide, futhi cishe ama-20% asebenzisa izinto zefilimu ze-polyester. Izinto ze-polymide zinokuvutha okuvuthayo, ubukhulu be-geometrical geometrical futhi banamandla okuvunyelwa okuphezulu, futhi bakwazi ukumelana namazinga okushisa we-welding, i-polyethyletereredate ebizwa ngokuthi yi-polyimides, i-dielethyric asniant ebizwa ngokuthi yi-polyimides, ithola umswakama omncane ophansi, idonsa umswakama omncane ophansi, kepha ayiveli phezulu amazinga okushisa. I-Polyester inendawo yokuncibilika engu-250 ° C kanye lokushisa kwengilazi (TG) ka-80 ° C, okukhawulela ukusetshenziswa kwawo kwizicelo ezidinga ukufudumala okubanzi. Ezicelo zokushisa eziphansi, zibonisa ukuqina. Noma kunjalo, zilungele ukusetshenziswa kwimikhiqizo efana nezingcingo kanye nabanye abangadingi ukuvezwa kwezindawo ezinokhahlo. Ifilimu le-polymide infating livame ukuhlanganiswa ne-polymide noma adhesive adhesive, impahla ye-polyester insulating ngokuvamile ihlanganiswe nokunamathela kwe-polyester. Inzuzo yokuhlanganisa enezinto ezibonakalayo ezinezici ezifanayo zingaba nokuqina kobukhulu ngemuva kokushiswa komile noma ngemuva kwemijikelezo eminingi yokulamula. Ezinye izakhiwo ezibalulekile ezinama-adhesives zingu-dielectric ophansi njalo, ukumelana okuphezulu okuphezulu, izinga lokushisa le-glass eliphakeme kanye nokutholwa komswakama ophansi.

2. Isiphilisi

I-Copper Foil ilungele ukusetshenziswa emibuthanweni eguqukayo, ingaba ngogesi (ed), noma i-plated. I-foil ye-copper enokwenziwa kukagesi inendawo ecwebezelayo ngakolunye uhlangothi, kanti ingaphezulu kolunye uhlangothi lubuthuntu futhi lubuthuntu. Kuyinto eguquguqukayo enezinto eziguquguqukayo ezingenziwa ngobukhulu obuningi nobubanzi, futhi uhlangothi oluthukile lwe-foil ye-ed yethusi luvame ukuphathwa ngokukhethekile ukuthuthukisa ikhono layo lokubopha. Ngaphezu kokuguquguquka kwayo, i-foil yethusi ebonwe iphinde ibe nezimpawu zobulukhuni futhi obushelelezi, ezilungele izinhlelo zokusebenza ezidinga ukugoba okunamandla.

3. Adhesive

Ngaphezu kokusetshenziselwa ukuhlanganisa ifilimu elifaka ukufakwa kwezinto ezisebenzayo, okunamathela kungasetshenziswa njengesendlalelo sesembozo, njengenhlanganisela evikelayo. Umehluko omkhulu phakathi kwalawa manga amabili kuhlelo lokusebenza olusetshenzisiwe, lapho kufakwa khona isigaxa sefilimu yokufakelwa kwesembozo ukwakha isifunda esakhiwayo. Ubuchwepheshe bokuphrinta isikrini obusetshenziselwa ukuhlanganisa okunamathelayo. Akuwona wonke ama-laminates aqukethe ama-adhesives, futhi ama-laminates ngaphandle kokuba anama-adhesives aphumela kwimibuthano emincane nokuguquguquka okukhulu. Uma kuqhathaniswa nesakhiwo se-lamonated kususelwa ekunamatheleni, kunokuvuselelwa okungcono okushisayo. Ngenxa yesakhiwo esincanyana somjikelezo oguquguqukayo ongenakunamathela, futhi ngenxa yokuqedwa kokumelana okushisayo kokunamathela, ngaleyo ndlela kuthuthukise ukusebenza okushisayo, kungasetshenziswa endaweni yokusebenza lapho kusebenza khona i-adhesive.

Ukwelashwa Okungaphezulu

Enqubweni yokukhiqiza, ukuze kuvikeleke umjikelezo ovulekile kakhulu futhi kubangele isivuno esiphansi kakhulu noma ukunciphisa ukumba, izinkinga zokuphinda zibangelwa ama-FPC Board scrap, ukugcwaliswa kwezinkinga ezinzima okubangelwa ukufezekisa amabhodi amakhasimende aguqukayo, ukwelashwa kwangaphambi kokubaluleka ikakhulukazi.

Ukwelashwa kwangaphambi kwalokho, kunezici ezintathu ezidinga ukubhekwana nazo, futhi lezi zici ezintathu ziphothulwa onjiniyela. Owokuqala ukuhlolwa kwezobunjiniyela ze-FPC, ikakhulukazi ukuhlola ukuthi iBhodi yeKhasimende le-FPC lingakhiqizwa yini, ngabe umthamo wenkampani ekhiqizwa yinkampani angahlangabezana nezidingo zebhodi lekhasimende nezindleko zeyunithi; Uma kudluliselwa ukuhlolwa kwephrojekthi, isinyathelo esilandelayo ukulungiselela izinto ngokushesha ukuze uhlangabezane nokuhlinzekwa kwezinto zokusetshenziswa kwesixhumanisi ngasinye sokukhiqiza. Ekugcineni, unjiniyela kufanele: Umdwebo we-CAD weKhasimende, idatha ye-Gerber Line kanye neminye imibhalo yobunjiniyela iyacutshungulwa ukuze ihambisane nemvelo yokukhiqiza kanye nemidwebo yokukhiqiza kanye neminye imidwebo) kanye neminye imidwebo, ukutholakala kweminyango kanye neminye iminyango ukufaka inqubo yokukhiqiza ejwayelekile.

Inqubo yokukhiqiza

Uhlelo lwamaphaneli amabili

Ukuvula → Ukuvulwa → Pth → → Electroplating → Ukuhlekisa Ukulinganiswa → Ukubhoboza → Ukuhlola kokugcina → Ukupakisha → Ukuthumela

Uhlelo lwephaneli elilodwa

Ukuvula → Ukuvulwa → ukunamathela kwifilimu eyomile → Ukuqondanisa → Ukuvezwa
