8 Isendlalelo se-HASL FPC+FR4 Rigid-Flex PCB
Mayelana ne-Rigid-Flex PCB
Ukuzalwa nokuthuthukiswa kwe-FPC ne-PCB kwazala umkhiqizo omusha we-Rigid-Flex PCB.Ngakho-ke, inhlanganisela ye-PCB eguquguqukayo kanye ne-Rigid PCB iwuhlobo lwebhodi lesifunda le-PCB elinezici ze-FPC nezici ze-PCB, elakhiwe ngokuhlanganisa ibhodi lesifunda eliguquguqukayo kanye nebhodi lesifunda eliqinile ndawonye ngokuvumelana nezidingo zenqubo efanele ngokucindezela nezinye izinqubo.Ngenxa yokuthi i-Rigid-Flex PCB iyinhlanganisela ye-FPC ne-PCB, ukukhiqizwa kwe-FPC ne-PCB kufanele kufakwe izinto zokukhiqiza ze-FPC kanye nemishini yokukhiqiza ye-PCB ngesikhathi esisodwa.
Ukucubungula Ubunzima Be-Rigid-Flex PCB
Ingxenye ye-PCB eguqukayo:
(1) Imishini yokukhiqiza ye-PCB eqinile ukuze ikhiqize i-Plexible PCB.Njengoba impahla ye-Flexible PCB ithambile futhi izacile, i-Flexible PCB edlula kuyo yonke imigqa evundlile kufanele iphathwe ngepuleti lokudonsa ukuze igweme ukulahlwa.
(2) Ukwelashwa kwe-chip eyodwa ngaphambi kokuba i-lamination nayo ibe nomthelela omkhulu ekuqondaneni kwe-interlayer.Ngenxa yokuthi izinto ze-polyimide azimelani ne-alkali eqinile futhi zikhukhumala esixazululweni se-alkali esiqinile, ngesikhathi sokwenza mnyama nokuba nsundu, izinga lokushisa kanye nesikhathi kufanele kwehliswe ngokufanelekile ezinqubweni eziqinile ze-alkali ezifana nokuwohloka, ukwenza mnyama nokuba nsundu.
(3) Ngenxa yokuthi ishidi eliguquguqukayo kulula ukuligoba, ukucaba ngaphambi kokuba i-lamination impofu, futhi uketshezi lwe-resin lweshidi lokunamathisela luphansi kakhulu kunalelo leshidi eliphulukisiwe elisetshenziselwa ukucwiliswa kwepuleti eliqinile.Ngakho-ke, ukuze senze ucezu olubophezelayo kanye nocezu olulodwa luhlanganiswe kahle futhi lufakwe emgqeni omuhle wokuhlukanisa umugqa, sikhetha ukusebenzisa izinto ezinempahla yokumboza enhle njengezinto ze-cushion laminated, njengefilimu ye-polypropylene, i-PTFE, i-silicon Ikhwalithi ye-laminated yebhodi eguquguqukayo ingathuthukiswa ishidi lerabha
Ingxenye ye-PCB eqinile:
(1) I-warp ne-weft yendwangu yengilazi kufanele ihambisane, futhi ukucindezeleka okushisayo kanye ne-warpage kufanele kuqedwe phakathi nenqubo yokucindezela.
(2) Ukulawula ingcindezi ye-Rigid-Flex PCB.Ngenxa yokungaqini kahle kwezinto zebhodi elithambile, kuyadingeka ukuqedela ukukhiqizwa kwe-Flexible PCB nokucindezela ifilimu emboza i-PI kuqala, bese wenza i-PCB Eqinile ngokuya ngokunwetshwa nokufinyezwa kwe-coefficient yayo.
(3) Ukuze kusetshenziswe iwindi eliguquguqukayo, ngokuvamile kuvame ukugaya nokugaya ngemva kokusika, kodwa ukucubungula okuguquguqukayo kufanele kwenziwe ngokuvumelana nesakhiwo nokuqina kwe-Rigid-Flex PCB.Uma iwindi eliguquguqukayo ligaywa okokuqala, ukunemba kokugaya kufanele kuqinisekiswe, okungeke kuthinte ukushisela noma ukuphambuka kakhulu.
Inzuzo Yokwenziwa Kwe-PCB Eqinile Eguquguqukayo
1.Sebenzisa ukukhiqizwa okuthambile, ukuqapha ngempumelelo inqubekelaphambili yokukhiqiza futhi uthuthukise izinga lokulethwa.
2.Ukwenziwa Ngokwezifiso Kochwepheshe: ukwenza ukuhlola, ukufunwa kwe-oda ye-PCB yeqoqo
3.Qedela isitifiketi somkhiqizo kanye nesitifiketi sohlelo lwefekthri
