Iqinile-i-flex PCB wuhlobo olusha lwebhodi lesifunda eliphrintiwe elihlanganisa ukuqina kwe-PCB eqinile kanye nokuguquguquka kwe-PCB eguquguqukayo (FPC). Phakathi kwazo zonke izinhlobo zamabhodi esekethe, i-PCB eguquguqukayo eqinile inikeza ukumelana okuqine kakhulu ezindaweni ezinokhahlo, okuwenza adume phakathi kwabakhiqizi bokulawulwa kwezimboni, kwezokwelapha, kanye nemishini yezempi. I-WonderfulPCB futhi kancane kancane ikhulisa ingxenye ye-PCB eqinile-flex ekukhiqizeni kwayo okuphelele.
Izinzuzo ze-rigid-flex PCB yizindawo zabo ezinhle kakhulu kuzo zombili PCB eqinile kanye nama-FPC aguquguqukayo. Zingagoqwa, zigobe, futhi zonge isikhala, kuyilapho zisavumela ukushisela okuyinkimbinkimbi kwezingxenye. Uma kuqhathaniswa nezintambo zendabuko, zinikeza isikhathi eside sokuphila, ukuzinza okuthembeke kakhulu, futhi azijwayele ukuphuka, i-oxidation, noma ukuhlukaniswa, okwenza ngcono kakhulu ukusebenza komkhiqizo. Kodwa-ke, i-PCB eguquguqukayo eqinile inezihibe ezithile: ukukhiqizwa kwayo kuhilela izinqubo eziningi, kunzima ukuyikhiqiza, inenani eliphansi lesivuno, idinga inani elikhulu lezinto ezibonakalayo nomsebenzi, okuyenza ibize futhi ibe nomjikelezo omude wokukhiqiza.
Yiziphi izinhlelo zokusebenza ze-rigid-flex PCB?
1.Sebenzisa Industrial - Lokhu kufaka phakathi izicelo ezimbonini ezifana nezinkundla zempi nezokwelapha. Izingxenye eziningi zezimboni zidinga ukunemba, ukuphepha, nokuqina, okwenza izakhiwo ezidingekayo ze-PCB eqinile eguquguqukayo zithembeke kakhulu, ukunemba okuphezulu, ukulahleka kwe-impedance ephansi, ikhwalithi yokudlulisela isignali enhle kakhulu, nokuqina. Kodwa-ke, ngenxa yobunzima benqubo, umthamo wokukhiqiza uncane, futhi intengo yeyunithi iphakeme kakhulu.
2.Omakhalekhukhwini - Izicelo ezijwayelekile ze i-rigid-flex PCB kumaselula afaka ihinge yamafoni asongekayo, amamojula ekhamera, i-keyPAD, namamojula e-RF.
3.Consumer Electronics - Emikhiqizweni yabathengi, i-DSC (amakhamera amile wedijithali) kanye ne-DV (ividiyo yedijithali) amadivayisi amele aqhuba ukuthuthukiswa kwe-PCB eguquguqukayo eqinile. Baxhuma amabhodi aqinile e-PCB nezingxenye ngobukhulu obuthathu, bakhulisa indawo ephelele esebenzisekayo ye-PCB ngenkathi begcina ukuminyana kwesifunda okufanayo. Lokhu kuthuthukisa umthamo wesekethe futhi kunciphisa imikhawulo yokudlulisela isignali namazinga amaphutha wokuhlanganisa. Ukwengeza, njengoba amabhodi aqinile-flexible elula, mncane, futhi evumelana nezimo, aba negalelo ekwehliseni usayizi womkhiqizo nesisindo.
4.Izithuthi - Ezimotweni, i-PCB eguquguqukayo eqinile isetshenziswa ezinhlelweni ezifana nezinkinobho zokuxhuma ezisondweni lomama, izikrini ezixhumanisa namaphaneli okulawula ezinhlelweni zevidiyo yemoto, izinkinobho zokulawula kumaphaneli eminyango yemoto, amasistimu wokucabanga we-radar ahlehlayo, izinzwa (ikhwalithi yomoya, izinga lokushisa, umswakamo, nokulawula igesi okukhethekile), izinhlelo zokuxhumana, amasistimu wokuzulazula wesathelayithi, amasistimu okulawula imoto angaphandle, nezihlalo zangaphandle.
Amaphuzu Abalulekile Ekwenzeni I-Rigid-Flex PCB Manufacturing
Ukudalwa nokuthuthukiswa kwama-FPC kanye ne-PCB kwazala i-PCB eqinile eguquguqukayo, eyakhiwe ngokuhlanganisa amabhodi wesifunda aguquguqukayo kanye namabhodi esekethe aqinile ngokusebenzisa izinqubo ezifana ne-lamination. Iphuzu elibalulekile ekukhiqizeni i-PCB eguquguqukayo eqinile lisenqubweni ye-lamination, ikakhulukazi lapho kuhlangana khona izingxenye eziguquguqukayo neziqinile. Nakuba i-PCB ezimele noma izinqubo ze-FPC zokucwenga zivuthiwe, ukuhlanganisa lezi zinhlobo ezimbili kumabhodi aguquguqukayo aqinile kuhlala kuyinselele kubakhiqizi.
- Ukusetshenziswa kwemishini ye-vacuum lamination kuqinisekisa ingcindezi eqhubekayo kanye nezinga lokushisa lokunamathela okuhle nokubopha izinto ezibonakalayo.
- Izinto zokumboza ezifanele kufanele zikhethwe: isembozo esithambile singabonisa iminonjana yensimbi namaphethini phezulu, kuyilapho into eqinile kakhulu ingase ibangele ukucindezelwa okuncane namabhamuza.
Izinselelo Ekwenzeni I-Rigid-Flex PCB Manufacturing
I-PCB eguquguqukayo eqinile ibandakanya izinqubo eziyinkimbinkimbi, futhi ubuchwepheshe obuthile obubalulekile nezinselele okunzima ukuzilawula. Umehluko wesakhiwo kanye nokokusebenza phakathi kwamabhodi aguquguqukayo naqinile kubangela umehluko omkhulu ekuzinzeni kwawo kobukhulu, okwenza ukukhetha kwezinto ezifanele kubaluleke kakhulu ukuze kulungiswe kahle.
Okwesigaba esivumelana nezimo:
- Izinto ezithambile zidinga ukuqondiswa emugqeni wokukhiqiza kusetshenziswa ipuleti lenkampani yenethiwekhi ukugwema ukuminyana nokumoshakala.
- Ukuphatha okunembe kwezendlalelo ngazinye kubalulekile ekuqondaneni, ikakhulukazi ngenxa yokuzwela kwezinto ze-polyimide kuzixazululo ezinamandla ze-alkaline, ezingabangela ukuvuvukala.
- Izinga lokucwala lingathuthukiswa ngokusebenzisa izinto ezifanele zebhafa njengefilimu ye-polypropylene noma amashidi e-PTFE ukuze kuthuthukiswe ukuhlangana phakathi kwezendlalelo.
Okwesigaba esiqinile:
- Ukuqinisekisa ukuqondiswa okusanhlamvu okufanayo kwendwangu yengilazi ye-fiber kanye nokuqeda ukucindezeleka okushisayo ngesikhathi sokucwenga ukuvimbela ukulwa.
- Ukulawula ukunwetshwa kanye nokufinyela ngesikhathi sokucwala, ikakhulukazi ezingxenyeni eziguquguqukayo.
- Amafasitela e-Flex angacutshungulwa kusetshenziswa izindlela zangaphambi kokugaya noma zokugaya, kuye ngesakhiwo sebhodi nokushuba.
Umthelela Wentengo Yento Engavuthiwe Yenyuka Ezindlekweni Ze-Rigid-Flex PCB
Kusukela ngo-September 2020, amanani entengo e-CCL (copper clad laminate) anyuke kakhulu, eqhutshwa ukushoda kwezinto zokusetshenziswa kanye nesidingo esinamandla esisuka ezansi nomfula. Ukwenyuka kwezindleko zezinto ezingavuthiwe, ikakhulukazi ithusi, i-glass fiber, ne-resin, kwenyuse amanani e-CCL ngafinyelela ku-100%. Nokho, lokhu kunyuka kwentengo kube nomthelela omncane uma kuqhathaniswa ezindlekweni ze-PCB eziguquguqukayo eziqinile, ngoba izindleko zezinto ezibonakalayo zenza ingxenye encane yezindleko eziphelele uma kuqhathaniswa ne-PCB evamile.
Amaphuzu Okulawula Ikhwalithi Kumojuli Yekhamera Eqinile-I-Flex PCB Manufacturing
Imojula yekhamera i-rigid-flex PCB inzima kakhulu ukwenziwa ngenxa yesikhala esincane (2-3 mil) phakathi kwe-COB (chip-on-board) PAD kanye nesidingo sokwelashwa okungaphezulu njenge-ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold), okungaholela ekushoniseni eceleni. Ukubhekana nalokhu, izinselele ezimbili kufanele zixazululwe:
- I-Fine Line Etching - Ukuphatha osayizi abancane be-COB PAD, imishini yokuvezwa ye-LDI (i-laser direct imaging) kufanele isetshenziswe, njengoba inikeza ukulungiswa okuphezulu kunemishini yendabuko. Lokhu kusiza ukugwema ukungahambi kahle ngesikhathi sokuchayeka.
- I-Solder Mask Side-Etch Control – Uyinki wemaski ocolisekileyo kufanele usetshenziselwe ukunciphisa izimbotshana kuyinki, okungaholela emazingeni aphezulu okucwenga ohlangothini kanye namasekethe amafushane ngesikhathi sokwelashwa kwendawo.
Ekugcineni, i-rigid-flex I-PCB prototyping futhi ukukhiqiza kuhilela izinselele eziyingqayizivele ngenxa yesakhiwo sazo sezinto ezibonakalayo kanye nezicelo, ezidinga ukulungiswa kuzo zonke izinyathelo zokukhiqiza ukuze kuthuthukiswe izinqubo namapharamitha.
