Amanyathelo okukhetha iPCB Material echanekileyo
Khetha Ngokusekelwe kwiFrequency
Sebenzisa izinto ezinciphisa ilahleko njengeRogers 5880 ukuze iradar esetyenziswa rhoqo.
Khetha i-FR-4 eguquliweyo kwii-applications ezingabizi kakhulu nezingenamda.
Cinga ngeeMfuno zamandla kunye nobushushu
Iiradar ezinamandla aphezulu kufuneka zisebenzise izixhobo ezinobushushu obuphezulu, ezifana nee-laminates ezisekelwe kwisinyithi.
Tshatisa Iimeko Zendalo
Iirada zomkhosi nezeenqwelo-moya zixhamla kwizinto ezishushu kakhulu nezimelana nokufuma ezifana ne-PTFE okanye i-polyimide.
Ukusebenza okulinganiselweyo kunye neendleko
Kwiiprojekthi ezinebhajethi encinci, khetha i-FR-4 eguquliweyo ngelixa uqinisekisa ukuba iyahlangabezana nemigangatho yokusebenza ebalulekileyo.
Iimpazamo eziqhelekileyo ekukhetheni izinto zePCB
Ukuthembela kuphela kwiSinto enye
Iimodyuli ezahlukeneyo zeradar zinokufuna izixhobo ezahlukeneyo zePCB. Umzekelo, iimodyuli zeRF zifuna iiRogers, ngelixa iimodyuli zolawulo zingasebenzisa i-FR-4.
Ukujonga ulawulo lwe-Thermal
Nokuba kukho izixhobo ezisebenza kakuhle kubushushu, uyilo olufanelekileyo lwesinki yobushushu luyimfuneko ukuze kususwe ubushushu ngempumelelo.
Ukungayinanzi Ingxaki Yokuvelisa
Izixhobo ezisebenza kakuhle zihlala zifuna ubuchule obukhethekileyo bokucubungula, ngoko ke qiniseka ukuba umthengisi wakho unako ukujongana nezi ngxaki.
Isiphelo: Isitshixo sokuSebenza kakuhle kwePCB yeRadar
Ukukhetha izixhobo ze-PCB ezifanelekileyo kubalulekile ukuze kuphuculwe ukusebenza kwenkqubo yerada, ukuthembeka, kunye nokusebenza kakuhle kweendleko.
