Iipropathi kunye neendlela zokhetho zezixhobo zebhodi yesekethe eziguqukayo

(1) FPC substrate

I-Polyimide isetyenziswa ngokubanzi njengezinto zebhodi yesekethe eguqukayo, enobushushu obuphezulu obunganyangekiyo kunye namandla aphezulu epolymer. Zizinto zepolymer eziyilwe yiDuPont. IPolyimide eveliswe yiDuPont ibizwa ngokuba yiKapton. Ukongeza, unokuthenga ezinye iipolyimides eziveliswe eJapan, ezingabizi kakhulu kuneDuPont.

Iyakwazi ukumelana nobushushu be-400 ℃ kwimizuzwana eyi-10 kwaye inamandla angama-15000-30000 psi.

amashumi amabini anesihlanu μ M ubukhulu be-FPC substrate yeyona nto inexabiso eliphantsi kwaye isetyenziswa kakhulu. Ukuba ibhodi yesekethe eguqukayo ifuna ukuba nzima, kufuneka kukhethwe i-50m isiseko sezinto. Ngokuchasene noko, ukuba ibhodi yesekethe eguqukayo kufuneka ithambe, khetha i-13 μ M yezinto ezisisiseko.

(2) Ukuncamathela okungafihliyo kwe-FPC substrate

Yahlulwe nge-epoxy resin kunye ne-polyethylene, zombini ezi zinto zinamathelisi e-thermosetting. Amandla e-polyethylene asezantsi kakhulu. Ukuba ufuna ibhodi yesekethe ithambe, khetha i-polyethylene.

Ukutyeba kwe-substrate kunye nokubambelela okungafihli kuyo, kokukhona kunzima ibhodi yesekethe. Ukuba ibhodi yesekethe inendawo enkulu yokugoba, i-substrate encinci kunye nokuncamathela okucacileyo kufuneka kukhethwe kangangoko kunokwenzeka ukunciphisa uxinzelelo kumphezulu wefoyile yobhedu, ukuze ithuba lokuqhekeka okuncinci kwifoyile yobhedu lincinci. Ewe kunjalo, kwimimandla enjalo, iibhodi eziluhlu olulodwa kufuneka zikhethwe kangangoko kunokwenzeka.

(3) FPC ngefoyile yobhedu

Yahlulwe ngobhedu lwekhalenda kunye nobhedu lwe-electrolytic. Ubhedu lwekhalenda lunamandla aphezulu kunye nokugoba ukuxhathisa, kodwa ixabiso liyabiza. Ubhedu lwe-Electrolytic lubiza kakhulu, kodwa lunamandla amabi kwaye kulula ukuluqhekeza. Ihlala isetyenziswa kwimeko ezinamajiko ambalwa.

Ubunzima befoyile yobhedu buya kukhethwa ngokobubanzi obuncinci kunye nesithuba esincinci sezikhokelo. Ubuncinci befoyile yobhedu, ubuncinci ubuncinci ububanzi kunye nokushiyana okungafezekiswa.

Xa ukhetha ubhedu lwekhalenda, nikela ingqalelo kwicala lokwehla kwefoyile yobhedu. Ulwalathiso lwe-calendering lwefoyile yobhedu luya kuhambelana nolwalathiso oluphambili lwebhodi yesekethe.

(4) Ifilimu ekhuselayo kunye nokubambelela okungafihliyo kuyo

Kwangokunjalo, i-25 μ M ifilimu ekhuselekileyo iya kwenza ukuba ibhodi yesekethe eguqukayo ibe nzima, kodwa ixabiso lincinci. Kwibhodi yesekethe yokugoba okukhulu, kungcono ukhethe ifilimu ekhuselayo ye-13 μ M.

Ukuncamathela okungafaniyo ukwahlulwe kwayinxalenye ye-epoxy resin kunye ne-polyethylene. Ibhodi yesekethe isebenzisa i-epoxy resin kunzima kakhulu. Emva kokucinezela okushushu, into yokuncamathelisa elubala iya kukhutshelwa ngaphandle komphetho wefilimu yokhuselo. Ukuba ubungakanani bephedi bukhulu kunobungakanani bokuvulwa kwefilimu yokhuselo, i-adhesive ekhutshiweyo iya kunciphisa ubungakanani bephedi kwaye ibangele imiphetho engafanelekanga. Ngeli xesha, i-13 kufuneka ikhethwe ngokungangoko kunokwenzeka μ M yokuncamathela okucacileyo okubonakalayo.

(5) Ipeyinti yokutyabeka

Kwibhodi yesekethe yokugoba okukhulu kunye nenxalenye yephedi eveziweyo, i-electroplated nickel + i-electroless plating layer iya kwamkelwa, kwaye umaleko we-nickel uya kuba mncinci ngangokunokwenzeka: 0.5-2 μ m. Ubume begolide beekhemikhali 0.05-0.1 μ m.
