Metal base copper clad plate uye FR-4 maviri anowanzo shandiswa akadhindwa redunhu bhodhi (PCB) substrates muindasitiri yemagetsi. Iwo anosiyana mukuumbwa kwezvinhu, maitiro ekuita uye minda yekushandisa. Nhasi, Fastline inokupa iwe kuenzanisa kuongorora kwezvinhu zviviri izvi kubva kune nyanzvi maonero:
Metal base copper clad plate: Isimbi-yakavakirwa PCB zvinhu, kazhinji inoshandisa aluminium kana mhangura seyo substrate. Chinhu chayo chikuru ndechekuita kwekushisa kwekushisa uye kukwanisa kupisa kupisa, saka inonyanya kufarirwa mumashandisirwo anoda high thermal conductivity, zvakadai semwenje we LED uye magetsi ekushandura. Iyo simbi substrate inogona kunyatso kuitisa kupisa kubva kunzvimbo dzinopisa dzePCB kuenda kubhodhi rese, nekudaro kuderedza kupisa kwekuvaka-up uye nekuvandudza kushanda kwese kwechigadzirwa.
FR-4: FR-4 chinhu chine laminate chine girazi fiber jira sechinhu chinosimbisa uye epoxy resin sebinder. Parizvino ndiyo inonyanya kushandiswa PCB substrate, nekuda kwesimba rayo rakanaka remagetsi, zvivakwa zvemagetsi zvekudzivirira uye zvigadziriso zvemoto uye inoshandiswa zvakanyanya mumhando dzakasiyana dzezvigadzirwa zvemagetsi. FR-4 ine flame retardant rating ye UL94 V-0, zvinoreva kuti inopisa mumurazvo kwenguva pfupi uye yakakodzera kushandiswa mumidziyo yemagetsi ine yakakwira kuchengetedza zvinodiwa.
musiyano mukuru:
Substrate material: Metal copper-clad panels anoshandisa simbi (sealuminum kana mhangura) seye substrate, nepo FR-4 inoshandisa fiberglass jira uye epoxy resin.
Thermal conductivity: Thermal conductivity of the metal clad sheet yakakwirira kudarika iyo FR-4, iyo inokodzera kushandiswa kunoda kunaka kwekupisa.
Huremu uye ukobvu: Simbi yakapfeka mhangura mapepa anowanzo kurema kupfuura FR-4 uye anogona kunge akatetepa.
Maitiro ekugadzirisa: FR-4 iri nyore kugadzirisa, yakakodzera kune yakaoma yakawanda-layer PCB dhizaini; Metal clad mhangura ndiro yakaoma kugadzirisa, asi yakakodzera kune imwechete-layer kana yakapusa yakawanda-layer dhizaini.
Mutengo: Mutengo wesimbi yakavharwa pepa remhangura unowanzo kukwira kupfuura FR-4 nekuda kwemutengo wesimbi wepamusoro.
Zvishandiso: Metal akapfeka mahwendefa emhangura anonyanya kushandiswa mumidziyo yemagetsi inoda kupisa kwakanaka, semagetsi emagetsi uye mwenje we LED. Iyo FR-4 inoshanda zvakasiyana-siyana, yakakodzera kune akawanda akajairwa zvigadzirwa zvemagetsi uye akawanda-layer PCB dhizaini.
Kazhinji, kusarudzwa kwesimbi yakashongedzwa kana FR-4 inonyanya kuenderana nezvinodiwa zvekupisa zvechigadzirwa, dhizaini yakaoma, mutengo bhajeti uye kuchengetedza zvinodiwa.
