Ke lisebelisoa life tse sebelisoang hangata bakeng sa prototyping ea PCB?

Ha ho tluoa ho prototyping ea PCB, ho bohlokoa ho khetha thepa e nepahetseng e fihlelang litlhoko tsa projeke le maemo a indasteri. Capel o na le boiphihlelo ba lilemo tse 15 indastering ea boto ea potoloho mme o fana ka lisebelisoa tse fapaneng bakeng sa prototyping ea PCB, ho kenyeletsoa li-PCB tse feto-fetohang tse ngata, li-PCB tse thata-thata le li-PCB tse thata. E na le likhetho tsa eona tsa feme le tsa ho itlhophisa, Capel ke khetho e tšepahalang bakeng sa litlhoko leha e le life tsa prototyping ea PCB.

PCB prototyping ke mohato oa bohlokoa ts'ebetsong ea tlhahiso ea boto ea potoloho e hatisitsoeng.E lumella bahlahisi le baenjiniere ho leka le ho lekola ts'ebetso ea meralo pele ho tlhahiso e kholo. Thepa e sebelisoang ho prototyping ea PCB e phetha karolo ea bohlokoa ho lekanyeng ts'ebetso, ts'epahalo le litšenyehelo tsa sehlahisoa sa ho qetela.

Capel o utloisisa bohlokoa ba ho sebelisa thepa ea boleng bo holimo nakong ea ts'ebetso ea prototyping ea PCB.Ka phihlelo e pharaletseng ea indasteri ea boto ea potoloho, ba khethile lisebelisoa tse sebelisoang ka ho fetisisa bakeng sa mefuta e sa tšoaneng ea likopo. A re hlahlobeng tse ling tsa lisebelisoa tsena le thepa ea tsona.

1.FR-4:
FR-4 ke lisebelisoa tse sebelisoang ka ho fetesisa ho tsa tlhahiso ea PCB le prototyping. Ke thepa e kopantsoeng e entsoeng ka lesela le lohiloeng la fiberglass le kenngoeng ka sekhomaretsi sa epoxy resin. FR-4 e na le thepa e ntle ea ho kenya motlakase, matla a mochini le botsitso bo botle ba sebopeho. Likarolo tsena li etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng, ho kenyeletsoa lisebelisoa tsa elektronike tsa bareki, litsamaiso tsa taolo ea indasteri le lisebelisoa tsa elektronike tsa likoloi.

2. Thepa e feto-fetohang:
Li-PCB tse feto-fetohang li ntse li tsebahala haholo ka lebaka la bokhoni ba tsona ba ho koba le ho ikamahanya le libopeho le libaka tse fapaneng. Liboto tsena li entsoe ka li-substrates tse feto-fetohang tse kang polyimide (PI) kapa polyester (PET). Li-PCB tse feto-fetohang tse thehiloeng ho polyimide ke khetho e tloaelehileng ka ho fetisisa ka lebaka la ho hanyetsa mocheso o babatsehang, matla a phahameng a dielectric le ho tšoarella hantle ha mochine. Li sebelisoa haholo lits'ebetsong tse kang liaparo, lisebelisoa tsa bongaka le lisebelisoa tsa elektroniki tsa sefofane.

3. Lisebelisuoa tse sa fetoheng:
Rigid-flex PCB e kopanya melemo ea PCB e thata le e tenyetsehang. Li na le mekhahlelo e mengata ea lipotoloho tse tenyetsehang tse hokahaneng le likarolo tse thata. Sebopeho sena se lumella boto hore e fetohe libakeng tse itseng ha e ntse e lula e tiile libakeng tse ling. Karolo e tenyetsehang hangata e entsoe ka polyimide, ha karolo e thata e sebelisa FR-4 kapa lisebelisoa tse ling tse thata. Li-PCB tsa Rigid-flex li loketse lits'ebetso tse hlokang motsoako oa ho feto-fetoha ha maemo le ts'ebetso ea motlakase, joalo ka lisebelisoa tsa sesole le lisebelisoa tsa elektroniki tse nkehang habonolo.

4. Lisebelisoa tsa maqhubu a phahameng:
Lisebelisoa tsa PCB tsa maqhubu a holimo li etselitsoe ho ts'ehetsa phetiso ea mats'oao ho maqhubu a kaholimo ho 1 GHz. Lisebelisoa tsena li na le tahlehelo e tlase ea dielectric, ho monya mongobo o tlase, le thepa ea motlakase e tsitsitseng ho feta mefuta e mengata ea maqhubu. Hangata li sebelisoa mekhoeng ea puisano ea sathelaete, lisebelisoa tsa radar le meralo e potlakileng ea dijithale. Capel e ka fana ka lisebelisoa tse phahameng tsa PCB tse etselitsoeng litlhoko tse ikhethang tsa lits'ebetso tsena.

Bokhoni ba Capel ho prototyping ea PCB bo feta ho khetha lisebelisoa tse nepahetseng. Ba boetse ba fana ka likhetho tsa ho iketsetsa tse tsamaellanang le litlhoko tse ikhethang tsa projeke ka 'ngoe. Hore na o hloka PCB e feto-fetohang ea mekhahlelo e mengata, PCB e sa fetoheng, kapa PCB e thata, Capel e na le bokhoni le boiphihlelo ba ho fana ka lipapiso tsa boleng bo holimo.

Ka kakaretso, Ho khetha lisebelisoa tse nepahetseng bakeng sa prototyping ea PCB ho bohlokoa katlehong ea morero ofe kapa ofe. Capel e sebelisa lilemo tsa eona tsa 15 tsa boiphihlelo ba indasteri le lifeme tsa eona ho fana ka lisebelisoa tse ngata tse fapaneng, ho kenyeletsoa FR-4, lisebelisoa tse feto-fetohang, tse thata-thata le lisebelisoa tse phahameng haholo. Bokhoni ba bona le likhetho tsa khetho ea bona li ba etsa molekane ea tšepahalang bakeng sa litlhoko tsohle tsa hau tsa prototyping ea PCB.
