Litlhokahalo tsa ho Coating Conformal Moralong oa Rigid-Flex PCB ke life?

Matsatsing ana, lisebelisoa tsa elektroniki liindastering tse fapaneng ke sepheo se seholo sa ho lelekisa lihlahisoa tse ntle, tse nyane empa tse sebetsang ka botlalo. Boima bo bobebe le mamello ea sebaka se phahameng saRegid-Flex PCBli etse hore li tšoanelehe bakeng sa liindasteri tse fapaneng, ho kenyeletsoa sebaka sa sefofane, lisebelisoa tsa bongaka, lisebelisoa tsa taolo ea indasteri, le lisebelisoa tsa elektroniki tsa bareki. Leha ho le joalo, moralo le tlhahiso ea PCBS e thata-thata e na le litlhoko tse khethehileng tsa thepa le menahano ea ts'ebetso, haholo ha ho tluoa tabeng ea ho roala ka mokhoa o ts'oanang. Ka pampiri ena, litlhoko tsa li-coatings tse lumellanang kaRegid-FlexHo tšohloa moralo oa PCB, 'me liphello tsa bona ho litlhoko tsa thepa ea PCB, ts'ebetso ea moralo le ts'ebetso ka kakaretso li tšohloa.

Litlhoko tsa Lintho tsa PCB

Khetho ea lisebelisoa e bohlokoa ho moralo oa Rigid-Flex PCB. Lisebelisoa ha lia lokela ho ts'ehetsa ts'ebetso ea motlakase feela empa hape li mamella khatello ea mochini le maemo a tikoloho. Lisebelisoa tse tloaelehileng tse sebelisoang ho Rigid-Flex PCB li kenyelletsa:

  • Polyimide (PI): E tsejoa ka botsitso ba eona bo botle ba mocheso le ho feto-fetoha ha maemo, polyimide e atisa ho sebelisoa bakeng sa likarolo tse feto-fetohang tsa Rigid-Flex PCBs.
  • FR-4: Thepa e sebelisoang haholo bakeng sa likarolo tse thata, FR-4 e fana ka lisebelisoa tse ntle tsa motlakase le matla a mochine.
  • Koporo: E bohlokoa bakeng sa litsela tsa conductive, koporo e sebelisoa ka mefuta e sa tšoaneng ho itšetlehile ka litlhoko tsa moralo.

Ha u sebelisa seaparo sa conformal, ho bohlokoa ho nahana ka ho lumellana ha lisebelisoa tsena le lintho tsa ho roala. Ho roala ho tlameha ho khomarela hantle ho substrate mme ho se ke ha ama hampe thepa ea motlakase ea PCB.

Kakaretso ea Coating Conformal

Conformal coating ke lera le sireletsang le sebelisoang ho li-PCB ho li sireletsa linthong tsa tikoloho joalo ka mongobo, lerōle, lik'hemik'hale le ho fetoha ha mocheso. Boemong ba li-PCB tsa Rigid-Flex, ho koaheloa ha li-conformal coating ho bohlokoa haholo ka lebaka la moralo o ikhethileng o kopanyang likarolo tse thata le tse tenyetsehang.

Lintlha tse ka Sehloohong bakeng sa Tšireletso ea Coating e Tloaelehileng

Sesebelisoa sa Uniform: Ho roala ho tlameha ho sebelisoa ka mokhoa o ts'oanang ho pholletsa le libaka tse peli tse thata le tse tenyetsehang ho netefatsa tšireletso e tsitsitseng. Karohano e sa lekanyetsoang e ka lebisa ho bofokoli libakeng tse itseng, e ka behang ts'ebetso ea PCB kotsing.

Taolo ea Botenya: Botenya ba ho roala conformal bo bohlokoa. Lera le letenya haholo le ka ama ho tenyetseha ha PCB, athe lera le lesesaane haholo le ka 'na la se ke la fana ka tšireletso e lekaneng. Baetsi ba tlameha ho laola ka hloko ts'ebetso ea kopo ho fihlela botenya bo lakatsehang.

Ho tenyetseha: The conformal barbotag e tlameha ho boloka botšepehi ba eona nakong ea ho kobeha le ho phunya ha PCB. Sena se hloka ho khetha litlolo tse etselitsoeng ka ho khetheha bakeng sa lisebelisoa tse tenyetsehang, ho netefatsa hore li ka mamella khatello ea mochine ntle le ho phunyeha kapa ho ebola.

Litlhoko tsa Ts'ebetso ea Rigid-Flex PCB
Mokhoa oa ho etsa li-PCB tsa Rigid-Flex o kenyelletsa mehato e mengata, e 'ngoe le e' ngoe e na le litlhoko tsa eona. Tsena li kenyelletsa:

Layer Stacking: Moralo o tlameha ho ikarabella bakeng sa ho bokellana ha likarolo tse thata le tse tenyetsehang, ho netefatsa ho tsamaisana hantle le ho khomarela pakeng tsa lisebelisoa tse fapaneng.

Ho Etching le ho Epa: Ho nepahala ke ntho ea bohlokoa ho etching le ho cheka lits'ebetso ho theha potoloho e hlokahalang. Ts'ebetso e tlameha ho laoloa ka hloko ho qoba ho senya likarolo tse tenyetsehang.

Kopo ea ho roala: Kopo ea ho roala ka mokhoa o ts'oanang e lokela ho kenngoa ts'ebetsong ea tlhahiso. Mekhoa e kang spray, dip, kapa coating e khethehileng e ka sebelisoa, ho itšetlehile ka moralo le litlhoko tsa thepa.

Ho phekola: Pholiso e nepahetseng ea ho roala ka mokhoa o ts'oanang ke ea bohlokoa ho fihlela thepa ea ts'ireletso e lakatsehang. Ts'ebetso ea ho folisa e tlameha ho ntlafatsoa ho netefatsa hore seaparo se khomarela hantle substrate ntle le ho ama ho fetoha ha PCB.
Tšebetso ea PCB e thata-Flex
Ts'ebetso ea li-PCB tsa Rigid-Flex e susumetsoa ke lintlha tse fapaneng, ho kenyelletsa khetho ea thepa, ho rarahana ha moralo, le katleho ea ho roala ha conformal. Rigid-Flex PCB e hlophisitsoeng hantle e nang le koae e loketseng e ka fana ka melemo e mengata:

  • Ntlafatso ea ho tšoarella: Ho roala ka mokhoa o hlophisitsoeng ho sireletsa khahlanong le khatello ea tikoloho, ho lelefatsa nako ea bophelo ea PCB.
  • Botšepehi bo Ntlafetseng: Ka ho sireletsa li-circuits, conformal coating e ntlafatsa ts'epahalo e akaretsang ea sesebelisoa, e fokotsa kotsi ea ho hloleha lits'ebetsong tsa bohlokoa.
  • Moqapi oa Fetola: Motsoako oa lintho tse thata le tse tenyetsehang li lumella meralo e ncha e ka ikamahanyang le mefuta e fapaneng ea mefuta, e etsa hore li-PCB tsa Rigid-Flex li loketse mefuta e mengata ea lits'ebetso.
