Izici nezindlela zokukhetha zezinto zokukhiqiza zebhodi lesifunda eziguquguqukayo

(1) I-FPC umugqa ongaphansi

I-Polyimide ivame ukusetshenziswa njengezinto zebhodi lesifunda eliguquguqukayo, okuyizinto ezinokushisa okuphezulu nokumelana namandla okuphezulu kwe-polymer. Kungumsebenzi we-polymer owasungulwa yiDuPont. I-polyimide ekhiqizwa yiDuPont ibizwa ngeKapton. Ngaphezu kwalokho, futhi ungathenga amanye ama-polyimides akhiqizwa eJapan, ashibhile kuneDuPont.

Ingamelana nokushisa okungama-400 ℃ amasekhondi ayi-10 futhi inamandla we-15000-30000 psi.

amashumi amabili nanhlanu μ M ubukhulu be-FPC substrate yiyona eshibhile futhi esetshenziswa kakhulu. Uma ibhodi lesifunda eliguquguqukayo lidinga ukuba nzima, kufanele kukhethwe okungama-50 μ M base material. Ngokuphambene nalokho, uma ibhodi lesifunda eliguquguqukayo lidinga ukuthamba, khetha okokusebenza okungu-13 μ M.

(2) Yesigcilikisha esobala ye-FPC substrate

Ihlukaniswe nge-epoxy resin ne-polyethylene, zombili okuyizinto zokunamathisela ze-thermosetting. Amandla e-polyethylene aphansi kakhulu. Uma ufuna ibhodi lesifunda lithambe, khetha i-polyethylene.

Ukujiya kwe-substrate nokunamathisela okusobala kuso, iba nzima ibhodi lesifunda. Uma ibhodi lesifunda linendawo enkulu yokugoba, kufanele kukhethwe i-substrate encanyana kanye nokunamathisela okusobala ngangokunokwenzeka ukunciphisa ukucindezeleka ebusweni besithombe sethusi, ukuze ithuba lokuqhekeka okuncane ku-foil yethusi libe lincane kakhulu. Vele, ezindaweni ezinjalo, kufanele kukhethwe amabhodi angongqimba olulodwa ngangokunokwenzeka.

(3) FPC zethusi ucwecwe

Ihlukaniswe ngethusi lekhalenda nethusi le-electrolytic. Ithusi elihleliwe linamandla amakhulu nokumelana nokugoba, kepha intengo iyabiza. I-Electrolytic yethusi ishibhile kakhulu, kepha inamandla amancane futhi kulula ukuyiphula. Imvamisa isetshenziswa ezimeni ezinokugoba okumbalwa.

Ubukhulu bocingo lwethusi luzokhethwa ngokuya ngobuncane besikhala kanye nesikhala esincane semikhondo. Okuncanyana kwe-foil yethusi, kuncane ububanzi obuncane nezikhala ezingatholakala.

Lapho ukhetha ithusi elihleliwe, naka ukuqondiswa kwekhalenda kocingo lwethusi. Ukuqondiswa kwe-calendering kwe-foil yethusi kuzofanelana nesiqondisi esikhulu sokugoba kwebhodi lesifunda.

(4) Ifilimu evikelayo nokunamathela okusobala kwalokho

Ngokufanayo, ifilimu yokuvikela engu-25 μ M izokwenza ibhodi lesifunda eliguquguqukayo libe nzima, kepha intengo ishibhile. Kwibhodi lesifunda elinokugoba okukhulu, kungcono ukhethe ifilimu yokuvikela eyi-13 μ M.

Isinamatheliso esibonakalayo sihlukaniswe saba yi-epoxy resin ne-polyethylene. Ibhodi lesifunda elisebenzisa i-epoxy resin linzima kakhulu. Ngemuva kokucindezela okushisayo, okunye okunamathelayo okusobala kuzokhishwa emaphethelweni efilimu evikelayo. Uma usayizi wephedi ukhulu kunosayizi wokuvula wefilimu evikelayo, i-adhesive extruded izokwehlisa usayizi wephedi futhi ibangele imiphetho engajwayelekile. Ngalesi sikhathi, kufanele kukhethwe i-13 ngangokunokwenzeka μ M ukunamathela okusobala okusobala.

(5) Pad enamathela

Okwebhodi lesifunda elinokugoba okukhulu nengxenye yephedi ivezwe, kuzokwamukelwa ungqimba we-elekthronikhi owenziwe ngogesi + ongafakwanga ugesi, futhi ungqimba lwe-nickel luzoba mncane ngangokunokwenzeka: 0.5-2 μ m. Isendlalelo segolide samakhemikhali 0.05-0.1 μ m.
