Metal base copper clad plate le FR-4 ke li-substrates tse peli tse hatisitsoeng ka tloaelo tse sebelisoang indastering ea lisebelisoa tsa elektroniki. Li fapane ka sebopeho sa thepa, litšobotsi tsa ts'ebetso le likarolo tsa ts'ebeliso. Kajeno, Fastline e tla u fa tlhahlobo ea papiso ea lisebelisoa tsena tse peli ho latela pono ea litsebi:
Metal base Copper clad plate: Ke lisebelisoa tsa PCB tse thehiloeng ka tšepe, hangata li sebelisa aluminium kapa koporo joalo ka substrate. Tšobotsi ea eona e ka sehloohong ke bokhoni bo botle ba ho futhumatsa mocheso le matla a ho senya mocheso, kahoo e tumme haholo lits'ebetsong tse hlokang mocheso o phahameng oa mocheso, joalo ka mabone a LED le li-converter tsa matla. The substrate tšepe ka ka katleho tsamaisa mocheso ho tloha matheba a chesang a PCB ho boto kaofela, ka tsela eo ho fokotsa mocheso ho haha-up le ho ntlafatsa tshebetso ka kakaretso ea sesebediswa.
FR-4: FR-4 ke thepa ea laminate e nang le lesela la fiber ea khalase e le thepa e matlafatsang le epoxy resin e le setlamo. Hajoale ke karolo e sebelisoang ka ho fetesisa ea PCB, ka lebaka la matla a eona a matle a mochini, thepa ea ho kenya motlakase le thepa e thibelang lelakabe mme e sebelisoa haholo lihlahisoa tse fapaneng tsa elektroniki. FR-4 e na le tekanyo e thibelang malakabe ea UL94 V-0, e bolelang hore e chesa lelakabe ka nako e khutšoanyane haholo 'me e loketse ho sebelisoa lisebelisoa tsa elektronike tse nang le litlhoko tse phahameng tsa tšireletso.
khetho ea bohlokoa:
Lisebelisoa tsa substrate: Lisebelisoa tsa tšepe tse entsoeng ka koporo li sebelisa tšepe (e kang aluminium kapa koporo) e le substrate, ha FR-4 e sebelisa lesela la fiberglass le resin ea epoxy.
Thermal conductivity: Thermal conductivity of metal clad sheet e phahame haholo ho feta ea FR-4, e loketseng likopo tse hlokang mocheso o motle oa mocheso.
Boima le botenya: Lishiti tsa koporo tse kentsoeng ka tšepe hangata li boima ho feta FR-4 mme li ka ba tšesaane.
Bokhoni ba ts'ebetso: FR-4 e bonolo ho e sebetsa, e loketse moralo o rarahaneng oa PCB oa mekhahlelo e mengata; Metal clad koporo poleiti ho thata ho sebetsa, empa e loketse bakeng sa lera le le leng kapa e bonolo multi-lara moralo.
Litšenyehelo: Litsenyehelo tsa letlapa la koporo la tšepe hangata li phahame ho feta FR-4 ka lebaka la theko e phahameng ea tšepe.
Lisebelisoa: Lipoleiti tsa koporo tse entsoeng ka tšepe li sebelisoa haholo-holo lisebelisoa tsa elektronike tse hlokang mocheso o motle oa mocheso, joalo ka motlakase oa motlakase le mabone a LED. FR-4 e sebetsa ka mokhoa o fapaneng, e loketse lisebelisoa tse ngata tsa elektroniki le meralo ea PCB ea mekhahlelo e mengata.
Ka kakaretso, khetho ea tšepe ea tšepe kapa FR-4 haholo-holo e itšetlehile ka litlhoko tsa tsamaiso ea mocheso oa sehlahisoa, ho rarahana ha moralo, tekanyetso ea litšenyehelo le litlhoko tsa polokeho.
