Likarolo tse sireletsang le lisebelisoa tsa PCB ea 8-layer ho thibela tšenyo le tšilafalo

Mokhoa oa ho khetha lera le sireletsang le lisebelisoa tsa ho koahela bakeng sa PCB ea 8-layer ho thibela tšenyo ea 'mele le tšilafalo ea tikoloho?

Selelekela:

Lefatšeng le potlakileng la lisebelisoa tsa elektroniki, liboto tsa potoloho tse hatisitsoeng (PCBs) li phetha karolo ea bohlokoa. Leha ho le joalo, likarolo tsena tse nepahetseng li kotsing ea ho senyeha 'meleng le tšilafalo ea tikoloho. Ho etsa bonnete ba hore e phela nako e telele le ts'ebetso e nepahetseng, ho bohlokoa ho khetha lesela le nepahetseng la tšireletso le lisebelisoa tse koahelang PCB ea hau ea 8-layer. Ho blog ena, re tla shebana le mokhoa oa ho khetha lintlha tsena tsa bohlokoa, re shebane le ho thibela tšenyo ea 'mele le tšilafalo ea tikoloho.

Thibelo ea tšenyo ea 'mele:

1. Nahana ka botenya le thepa ea lera le sireletsang:
Ha ho tluoa tabeng ea ho sireletsa PCB ea 8-layer ho tloha tšenyo ea 'mele, botenya le thepa ea lera le sireletsang li bohlokoa. Lera le letenya le sireletsang le fana ka khanyetso e ntle ho ts'usumetso le khatello ea mochini. Ka tsela e loketseng, lera le sireletsang le lokela ho etsoa ka thepa e tšoarellang e kang polyimide kapa FR-4 e ka mamellang matla a ka ntle.

2. Lekola matla a ho hanyetsa ha thepa ea ho koahela:
Ntle le lera le sireletsang, lisebelisoa tse koahelang li boetse li phetha karolo ea bohlokoa ho thibela tšenyo ea 'mele. Ke habohlokoa ho khetha thepa e koahelang e nang le tekanyo e phahameng ea tšusumetso. Lisebelisoa tse kang acrylic le polycarbonate li fana ka khanyetso e ntle haholo, e sireletsang li-PCB ho tloha marotholi a kotsi kapa likotlo.

3. Khetha tharollo ea ho roala:
Ho sebelisa lesela le khethehileng ho PCB ea 8-layer ke mokhoa o atlehang oa ho eketsa tšireletso e eketsehileng khahlanong le tšenyo ea 'mele. Liaparo tse phekolehang ka UV, liphahlo tse lumellanang le li-silicone ke likhetho tse tsebahalang. Liaparo tsena li hanyetsana le abrasion, lik'hemik'hale, mongobo le lerōle.

Thibelo le taolo ea tšilafalo ea tikoloho:

1. Sebelisa lisebelisoa tse baballang tikoloho:
Tšilafalo ea tikoloho ke bothata bo potlakileng lefatšeng la kajeno. Ha u khetha likarolo tse sireletsang le lisebelisoa tsa ho koahela bakeng sa li-PCB tsa 8-layer, ho bohlokoa ho khetha lisebelisoa tse sireletsang tikoloho. Batla lisebelisoa tse se nang lik'hemik'hale tse kotsi tse kang loto, mercury le litšepe tse boima. Khetha thepa e lumellanang le maemo a RoHS (Restriction of Hazardous Substances) ho fokotsa tšilafalo ea tikoloho le ho khothaletsa nts'etsopele ea moshoelella.

2. Batla litharollo tsa ho paka:
Encapsulation ke tsela e sebetsang ea 8-layer PCB ho thibela tšilafalo ea tikoloho. Ka ho koahela PCB ea hau ka lisebelisoa tse khethehileng, u theha mokoallo khahlanong le mongobo, lerōle, kutu, le litšila tse ling tsa tikoloho. Li-potting compounds, epoxies, le silicones ke lisebelisoa tse tloaelehileng tsa encapsulation tse tsejoang ka thepa ea tsona ea tšireletso.

3. Nahana ka mekhoa ea ho tiisa:
Ho kenyelletsa mochine oa ho tiisa moralong oa PCB oa 8-layer ho ka thibela tšilafalo ea tikoloho. Li-gaskets tse entsoeng ka thepa e kang neoprene kapa EPDM li ka fana ka thibelo e sebetsang khahlanong le mongobo le lerōle. Ho feta moo, litheipi tse nang le thepa e ntle ea ho tiisa li ka sebelisoa ho matlafatsa mochini oa ho tiisa.

Ha re phethela:

Ho khetha lera le nepahetseng la tšireletso le lisebelisoa tsa ho koahela bakeng sa PCB ea 8-layer ho bohlokoa ho thibela tšenyo ea 'mele le tšilafalo ea tikoloho. Ka ho nahana ka lintlha tse kang botenya, lisebelisoa, ho hanyetsa tšusumetso le botsoalle ba tikoloho, u ka etsa bonnete ba hore nako e telele le ts'ebetso e nepahetseng ea likarolo tsena tsa elektronike tse nepahetseng. Hopola, PCB e sirelelitsoeng hantle ha e atolose bophelo ba eona feela empa e boetse e khothalletsa mekhoa e tsitsitseng ka ho fokotsa tšilafalo ea tikoloho.Ka basebetsi ba 1500 le 20000 sqm ea tlhahiso le sebaka sa ofisi,Shenzhen Capel Technology Co., Ltd.e ne ethehoa ka 2009.Li-PCB tse bonololeLi-PCB tse thata-Flexbokgoni ba tlhahiso e ka fihla ho feta450000 sqm ka khoeli.
