FR4 PCBs ke eng?

FR4 PCB e bua ka mofuta oa boto ea potoloho e hatisitsoeng e entsoeng ka lelakabe la lelakabe la 4 (FR4) laminate.FR4 ke thepa e kopantsoeng e entsoeng ka lesela le lohiloeng la khalase le kenngoeng ka lelakabe la epoxy resin binder.Motsoako ona oa lisebelisoa o netefatsa hore li-PCB tsa FR4 li na le ts'ebetso e ntle ea motlakase, ho tšoarella le ho hanyetsa lelakabe.

Likarolo tsa FR4 PCB:

1. Motlakase oa motlakase: FR4 PCB e na le thepa e babatsehang ea ho kenya motlakase.Thepa ea fiberglass e sebelisoang ho laminate ea FR4 e tiisa matla a phahameng a ho senyeha, botšepehi ba pontšo e ka tšeptjoang le ho senya mocheso o sebetsang hantle.

2. Matla a mechine: Li-laminate tsa FR4 li fana ka matla a matla a mochine le botsitso ba sebopeho, ho etsa hore li tšoanelehe bakeng sa likopo tse sa tšoaneng.Li ka mamella mocheso o phahameng, ho thothomela le khatello ea tikoloho ntle le ho senya ts'ebetso.

3. Ho lieha ha lelakabe: E 'ngoe ea thepa ea bohlokoa ka ho fetisisa ea FR4 PCB ke ho lieha ha eona lelakabe.Sekhomaretsi sa epoxy se sebelisoang ho FR4 laminates se itima ka boeona, se thibelang ho ata ha mollo le ho tiisa polokeho e kholo ea thepa ea elektronike.

Melemo ea FR4 PCB:

1. Chelete e Ntle: FR4 PCB e na le mekhoa e mengata le e theko e tlaase, ha e bapisoa le li-substrates tse ling, e na le litšenyehelo tse ngata.Sena se ba etsa khetho ea pele bakeng sa mefuta e mengata ea lisebelisoa tsa elektroniki.

2. Ho feto-fetoha ha maemo: Li-PCB tsa FR4 li ka etsoa ka mokhoa o ikhethileng le ho etsoa ka boholo bo fapaneng, libopeho le mekhahlelo, ho lumella ho theoa ha meralo e rarahaneng ea potoloho le ho fihlela litlhoko tse fapaneng tsa likarolo.

3. Setsoalle sa tikoloho: FR4 PCB ha e na lintho tse kotsi tse kang loto kapa litšepe tse boima, kahoo e na le botsoalle ba tikoloho haholo.Li latela melaoana ea RoHS (Restriction of Hazardous Substances) mme li nkuoa li bolokehile bakeng sa bophelo bo botle ba batho le tikoloho.

Tšebeliso ea FR4 PCB:

Li-PCB tsa FR4 li sebelisoa indastering le lits'ebetsong tse fapaneng, ho kenyelletsa:

1. Consumer Electronics: Li-PCB tsa FR4 li sebelisoa haholo ho li-smartphone, matlapa, li-laptops, lithelevishene, lipapali tsa lipapali le lihlahisoa tse ling tsa elektronike, tse nolofalletsang lisebelisoa hore li sebetse ka botšepehi.

2. Lisebelisoa tsa indasteri: Li-PCB tsa FR4 li sebelisoa mecheng ea indasteri, litsamaiso tsa taolo, lisebelisoa tsa motlakase, le lisebelisoa tsa boiketsetso ka lebaka la litšobotsi tsa tsona tse phahameng tsa ts'ebetso le ho tšoarella.

3. Likoloi: Li-PCB tsa FR4 li bohlokoa bakeng sa lisebelisoa tsa elektronike tsa likoloi, ho kenyeletsoa mekhoa ea tsamaiso ea enjene, GPS navigation, infotainment systems, le tse ling.Ho hanyetsa lelakabe la bona le ho tiea ha bona ho netefatsa ts'ebetso e sireletsehileng le e ka tšeptjoang libakeng tse thata tsa likoloi.

Li-PCB tsa FR4 li fetotse indasteri ea lisebelisoa tsa elektroniki ka thepa ea tsona e phahameng ea motlakase le ea mochini, ho lieha ha lelakabe, le ho baballa litšenyehelo.Joalokaha re bone, ho feto-fetoha ha tsona le ho tšepahala ho etsa hore e be tse loketseng mefuta e mengata ea likopo.Bohlokoa ba bona ho lisebelisoa tsa elektronike tsa bareki, lisebelisoa tsa indasteri le indasteri ea likoloi li bonahala ts'ebetsong ea bona e ke keng ea lekanngoa ho netefatsa ts'ebetso e sireletsehileng le e ntle ea lisebelisoa tsa elektroniki.Ha theknoloji e ntse e tsoela pele ho fetoha, li-PCB tsa FR4 mohlomong li tla lula e le karolo ea bohlokoa ea lefatše la sejoale-joale.
