Isingeniso somkhiqizo
I-Flexible circuit board (FPC), eyaziwa nangokuthi ibhodi lesifunda eliguquguqukayo, ibhodi lesifunda eliguquguqukayo, isisindo salo esilula, ukushuba okuncanyana, ukugoba kwamahhala nokugoqa nezinye izici ezinhle kakhulu. Kodwa-ke, ukuhlolwa kwekhwalithi yasekhaya kwe-FPC kuncike kakhulu ekuhloleni okubonakalayo okwenziwa ngesandla, okuyizindleko eziphezulu nokusebenza kahle okuphansi. Ngokuthuthuka okusheshayo kwemboni yezogesi, idizayini yebhodi lesifunda iya ngokuya inemba kakhulu kanye nokuminyana okuphezulu, futhi indlela yendabuko yokuthola okwenziwa ngesandla ayisakwazi ukuhlangabezana nezidingo zokukhiqiza, futhi ukutholwa okuzenzakalelayo kwamaphutha e-FPC sekuyinto engenakugwemeka. umkhuba wokuthuthukiswa kwezimboni.
I-Flexible circuit (FPC) ubuchwepheshe obuthuthukiswe yi-United States ukuze kuthuthukiswe ubuchwepheshe berokhethi yasemkhathini ngeminyaka yawo-1970. Kuyisifunda esiphrintiwe esinokwethenjelwa okuphezulu kanye nokuguquguquka okuhle kakhulu okwenziwe ngefilimu ye-polyester noma i-polyimide njenge-substrate. Ngokushumeka umklamo wesifunda ephepheni lepulasitiki elincane eliguquguqukayo, inani elikhulu lezingxenye zokunemba lishunyekwa endaweni encane futhi enomkhawulo. Kanjalo kwakheka isekethe eguquguqukayo eguquguqukayo. Lo mjikelezo ungagotshwa futhi ugoqwe ngokuthanda kwakhe, isisindo esincane, usayizi omncane, ukuchithwa kahle kokushisa, ukufakwa kalula, ukugqekeza ubuchwepheshe bokuxhumanisa bendabuko. Ekwakheni kwesifunda esiguquguqukayo, izinto ezihlanganisiwe ziyifilimu evikelayo, umqhubi kanye ne-ejenti yokubopha.
Ingxenye yezinto 1, ifilimu yokufakelwa
Ifilimu ye-insulating yakha isendlalelo sesisekelo sesifunda, futhi i-adhesive ibopha i-foil yethusi kungqimba lwe-insulating. Ngomklamo onezingqimba eziningi, bese iboshelwa kungqimba lwangaphakathi. Zibuye zisetshenziswe njengesembozo sokuzivikela ukuze zivimbele isifunda othulini nomswakama, futhi ukunciphisa ukucindezeleka ngesikhathi sokuguquguquka, i-foil yethusi yakha isendlalelo se-conductive.
Kwezinye izifunda eziguquguqukayo, izingxenye eziqinile ezakhiwe nge-aluminium noma insimbi engagqwali zisetshenziswa, ezinganikeza ukuzinza kwe-dimensional, zinikeze ukusekelwa ngokomzimba ekubekweni kwezingxenye nezintambo, kanye nokukhulula ingcindezi. I-adhesive ibopha ingxenye eqinile kumjikelezo oguquguqukayo. Ukwengeza, enye into ngezinye izikhathi isetshenziselwa izifunda eziguquguqukayo, okuyisendlalelo sokunamathisela, esakhiwe ngokumboza izinhlangothi ezimbili zefilimu ye-insulating nge-adhesive. Ama-laminates anamathelayo ahlinzeka ngokuvikelwa kwemvelo kanye nokufakwa kwe-elekthronikhi, kanye nekhono lokuqeda ifilimu eyodwa encane, kanye nekhono lokuhlanganisa izingqimba eziningi ezinezingqimba ezimbalwa.
Kunezinhlobo eziningi zezinto zefilimu ezivikelayo, kodwa ezivame ukusetshenziswa kakhulu yi-polyimide ne-polyester. Cishe u-80% wabo bonke abakhiqizi besekethe abaguquguqukayo e-United States basebenzisa izinto zefilimu ye-polyimide, futhi cishe u-20% basebenzisa izinto zefilimu ye-polyester. Izinto ze-Polyimide zinokuvutha, ubukhulu bejiyomethri ezinzile futhi zinamandla amakhulu okudabula, futhi zinamandla okumelana nezinga lokushisa lokushisela, i-polyester, eyaziwa nangokuthi i-polyethylene double phthalates (i-Polyethyleneterephthalate ebizwa ngokuthi: PET), izakhiwo zayo zomzimba zifana ne-polyimides, ine-dielectric constant ephansi, idonsa umswakama omncane, kodwa ayimelani namazinga okushisa aphezulu. I-polyester inephuzu lokuncibilika elingu-250 ° C kanye nezinga lokushisa lengilazi (Tg) lika-80 ° C, elikhawulela ukusetshenziswa kwazo ezinhlelweni ezidinga ukushiselwa okubanzi kokuphela. Ezingeni lokushisa eliphansi izicelo, babonisa rigidity. Noma kunjalo, alungele ukusetshenziswa emikhiqizweni efana nezingcingo neminye engadingi ukuchayeka ezindaweni ezinokhahlo. Ifilimu yokuvikela i-Polyimide ivamise ukuhlanganiswa ne-polyimide noma i-acrylic adhesive, i-polyester insulating material ngokuvamile ihlanganiswa ne-polyester adhesive. Inzuzo yokuhlanganisa nempahla enezici ezifanayo ingaba nokuzinza kwe-dimensional ngemuva kwe-welding eyomile noma ngemva kwemijikelezo eminingi yokugcoba. Ezinye izinto ezibalulekile ezinamathelayo ziyi-dielectric engaguquki, ukumelana nokushisa okuphezulu, izinga lokushisa eliphezulu lokuguqulwa kwengilazi kanye nokumuncwa komswakama ophansi.
2. Umqhubi
I-copper foil ifaneleka ukusetshenziswa kumasekethe aguquguqukayo, ingaba yi-Electrodeposited (ED), noma i-plated. Icwecwe lethusi eline-deposition kagesi linendawo ecwebezelayo ngakolunye uhlangothi, kuyilapho ingaphezulu lolunye uhlangothi libuthuntu futhi lifiphele. Kuyimpahla eguquguqukayo engenziwa ngogqinsi nobubanzi obuningi, futhi uhlangothi olubuthuntu lwephepha lethusi le-ED livame ukuphathwa ngokukhethekile ukuze kuthuthukiswe ikhono layo lokubopha. Ngaphezu kokuguquguquka kwayo, i-foil yethusi ehlanganisiwe nayo inezici zokuqina futhi ezibushelelezi, ezifanele izinhlelo zokusebenza ezidinga ukugoba okuguquguqukayo.
3. Ingcina
Ngaphandle kokusetshenziselwa ukubopha ifilimu evikelayo ku-conductive material, i-adhesive ingasetshenziswa futhi njengesendlalelo sokumboza, njengesembozo sokuzivikela, futhi njengesembozo sokumboza. Umehluko omkhulu phakathi kwalokhu okubili ulele ekusetshenzisweni okusetshenzisiwe, lapho i-cladding eboshelwe kwifilimu yokufaka isembozo ukwakha isifunda esakhiwe nge-laminated. Ubuchwepheshe bokuphrinta isikrini obusetshenziselwa ukunamathisela okunamathelayo. Akuwona wonke ama-laminates aqukethe izinto zokunamathisela, futhi ama-laminates angenawo ama-adhesive aphumela kumasekhethi amancane kanye nokuguquguquka okukhulu. Uma kuqhathaniswa nesakhiwo se-laminated esekelwe ekunamatheleni, sinokusebenza okungcono kwe-thermal. Ngenxa yesakhiwo esincanyana sesifunda esiguquguqukayo esinganamatheli, futhi ngenxa yokuqedwa kokumelana okushisayo kwe-adhesive, ngaleyo ndlela kuthuthukise ukuqhutshwa kokushisa, kungasetshenziswa endaweni yokusebenza lapho isifunda esiguquguqukayo sisekelwe esakhiweni se-adhesive laminated. ayikwazi ukusetshenziswa.
Ukwelashwa ngaphambi kokubeletha
Enqubweni yokukhiqiza, ukuze kuvinjwe ukuvuleka kwesekethe emfushane kakhulu futhi kubangele isivuno esiphansi kakhulu noma ukunciphisa ukubhola, ikhalenda, ukusika kanye nezinye izinkinga zenqubo enzima ebangelwa izihlakala zebhodi le-FPC, izinkinga zokugcwalisa, futhi uhlole ukuthi ungakhetha kanjani izinto zokwakha ukuze uzuze okungcono kakhulu. imiphumela yokusetshenziswa kwamakhasimende kwamabhodi wesifunda aguquguqukayo, ukwelashwa kwangaphambili kubaluleke kakhulu.
Ukwelashwa kwangaphambili, kunezici ezintathu okudingeka kubhekwane nazo, futhi lezi zici ezintathu ziqedwa ngonjiniyela. Okokuqala ukuhlola ubunjiniyela bebhodi le-FPC, ikakhulukazi ukuhlola ukuthi ibhodi le-FPC yekhasimende lingakhiqizwa yini, ukuthi amandla okukhiqiza enkampani angakwazi yini ukuhlangabezana nezidingo zebhodi lekhasimende kanye nezindleko zeyunithi; Uma ukuhlolwa kwephrojekthi kuphasisiwe, isinyathelo esilandelayo ukulungisa izinto ngokushesha ukuze kuhlangatshezwane nokuhlinzekwa kwezinto ezingavuthiwe kusixhumanisi sokukhiqiza ngasinye. Okokugcina, unjiniyela kufanele: Umdwebo wesakhiwo se-CAD sekhasimende, idatha yomugqa we-gerber kanye neminye imibhalo yobunjiniyela kusetshenzwe ukuze ivumelane nendawo yokukhiqiza kanye nemininingwane yokukhiqiza yezinto zokusebenza, bese kuba imidwebo yokukhiqiza kanye ne-MI (ikhadi lenqubo yobunjiniyela) nezinye izinto zokwakha. ithunyelwe emnyangweni wokukhiqiza, ukulawulwa kwamadokhumenti, ukuthengwa kwempahla neminye iminyango ukuze ingene ohlelweni lokukhiqiza olujwayelekile.
Inqubo yokukhiqiza
