Iwe une kusahadzika, nei aluminium substrate iri nani pane FR-4?
Aluminium pcb ine maitiro akanaka ekugadzirisa, inogona kutonhora uye inopisa kukotama, kucheka, kuchera uye mamwe maitiro ekugadzirisa, kugadzira zvakasiyana-siyana zvezvimiro uye hukuru hwebhodhi redunhu. Iyo FR4 yedunhu bhodhi inowanzoita kutsemuka, kubvisa uye mamwe matambudziko, uye yakaoma kugadzirisa. Naizvozvo, aluminium substrate inowanzoshandiswa muzvigadzirwa zvemagetsi zvemhando yepamusoro, semwenje we LED, magetsi emotokari, magetsi uye mamwe minda.
Chokwadi, aruminiyamu pcb anewo zvimwe zvayakaipira. Nekuda kwesimbi yayo substrate, mutengo wealuminium substrate wakakwira, uye kazhinji unodhura zvakanyanya kupfuura FR4. Mukuwedzera, nokuti iyo aluminium substrate haisi nyore kusungirirwa nemapini emagetsi emagetsi emagetsi, kurapwa kwakakosha, zvakadai semetallization, kunodiwa, izvo zvinowedzera mari yekugadzira. Uye zvakare, iyo insulation layer yealuminium substrate inodawo kurapwa kwakakosha kuti ive nechokwadi chekupisa kupisa kuita pasina kukanganisa chiratidzo chekufambisa.
Pamusoro pekusiyana kwemutengo, kunewo mimwe misiyano pakati pealuminium pcb uye FR4 maererano nekuita uye kushandiswa kwemhando.
Chokutanga pane zvose, iyo substrate yealuminium ine zviri nani kupisa kupisa kushanda, iyo inogona kunyatsobvisa kupisa kunogadzirwa nebhodhi redunhu nokukurumidza. Izvi zvinoita kuti aluminium substrate inyatsokodzera kune-high-simba, high-density circuit design, yakadai semagetsi e LED, magetsi modules, nezvimwewo. Kusiyana neizvi, kupisa kwekushisa kweFR4 kunenge kusina simba, uye inonyanya kukodzera kune simba shoma. dhizaini yedunhu.
Chechipiri, ikozvino kutakura kugona kwealuminium substrate yakakura, iyo inokodzera kukwirisa frequency uye yakakwirira yazvino dunhu rekushandisa. Mukugadzirwa kwepamusoro-simba rekugadzirisa, ikozvino ichaita kupisa, uye iyo yakakwirira yekushisa kwekushisa uye yakanaka kupisa kupisa kwekushanda kwealuminium substrate inogona kunyatsobvisa kupisa, nokudaro kuve nechokwadi chekuvimbika uye kugadzikana kwedunhu. Ikozvino kutakura masimba eFR4 idiki uye haina kukodzera kune-simba-yakakwirira, yakakwira-frequency circuit magadzirirwo.
Pamusoro pezvo, aluminium substrate seismic performance iri nani pane FR4, inogona kuramba zvirinani kuvhunduka uye kudedera, saka mumotokari, njanji uye mamwe minda yemagetsi dhizaini dhizaini, aluminium substrate yakashandiswa zvakanyanya. Panguva imwecheteyo, iyo aluminium substrate inewo yakanaka anti-electromagnetic interference performance, inogona kunyatso kudzivirira mafungu emagetsi uye kuderedza kukanganiswa kwedunhu.
Kazhinji, aruminiyamu pcb ine nani kupisa kupisa kuita, ikozvino kutakura kugona, seismic kuita uye electromagnetic kupindira kuramba kupfuura FR4, uye yakakodzera kune yakakwirira-simba, yakakwirira-density uye yakakwirira-frequency redunhu dhizaini. FR4 inokodzera dhizaini yemagetsi yedunhu, senge nharembozha, malaptop uye zvimwe zvigadzirwa zvemagetsi zvevatengi. Mutengo wealuminium substrate unowanzo kukwirira, asi kune yakakwirira-inoda dhizaini dhizaini, kusarudzwa kwealuminium substrate inhanho yakakosha.
Muchidimbu, aruminiyamu pcb uye FR4 vakakodzera mhando dzakasiyana redunhu zvikumbiro uye vane zvazvakanakira nezvayakaipira. Paunenge uchisarudza wedunhu bhodhi zvinhu, zvinodikanwa kuyera akasiyana zvinhu zvinoenderana neakananga mashandisirwo mamiriro uye zvinodiwa kuti usarudze zvakanyanya zvakakodzera zvinhu.
