Yintoni i-ADAS PCB? Ukusetyenziswa kwamatyala kunye nezinto eziqwalaselwayo kuyilo
IiNkqubo zoNcedo lwaBaqhubi eziPhambili (i-ADAS) ziguqula ishishini leemoto ngokuphucula ukhuseleko lwezithuthi kunye namava okuqhuba. Embindini wezi nkqubo kukho icandelo elibalulekileyo—ii-ADAS PCBs (iiBhodi zeSekethe eziPrintiweyo).
Yintoni i-ADAS PCB?
Ii-PCB ze-ADAS ziibhodi zesekethe ezilungiselelwe ngokukodwa ezisetyenziswa kwi-elektroniki yeemoto ukuxhasa ukucutshungulwa kwedatha ngexesha langempela ukusuka kwiisensa ezifana neekhamera, i-radar, i-LiDAR, kunye neenkqubo ze-ultrasonic. Ezi PCB zifuna ukuthembeka okuphezulu, ukumelana nobushushu, kunye nokuhambelana kwe-electromagnetic ukuze zisebenze kwiindawo ezinzima zezithuthi.
Amatyala okusetyenziswa abalulekileyo e-ADAS PCBs
Ii-PCB ze-ADAS zisetyenziswa kakhulu kwezi zicelo zilandelayo:
- Isilumkiso sokungqubana Phambili (i-FCW): Isebenzisa idatha yeradar kunye nekhamera ukubona imiqobo kunye nokulumkisa umqhubi.
- Isilumkiso sokuHamba eLayini (LDW): Iqhuba igalelo elibonakalayo ukuze ibone ukuba imoto iyajika na kwindlela yayo.
- Ulawulo lokuHamba ngeNqanawa oluZiqhelanisayo (i-ACC): Igcina umgama okhuselekileyo isebenzisa impendulo yesenzi ngexesha langempela.
- Ukufunyanwa kweNdawo engaboniyo (BSD): Idibanisa i-radar esecaleni kunye nee-ultrasound sensors ukuze ibone izithuthi ezikufutshane.
- Ukubhreki okuNgxamisekileyo okuZenzekelayo (AEB): Ibangela ukuba ibhuleki xa kufunyenwe ingozi ezayo.
Izinto ekufuneka ziqwalaselwe kuyilo lwee-PCB ze-ADAS
Xa kuyilwa ii-PCB zeenkqubo ze-ADAS, kufuneka kuqwalaselwe izinto ezibalulekileyo:
- Ukunyaniseka kweSignali yesantya esiphezulu: Ngenxa yokuba idatha yeradar nekhamera ifuna ukuhanjiswa ngokukhawuleza, ukulawulwa kwe-impedance kunye nokulahleka okuncinci kubalulekile.
- Ulawulo lobushushu: Iimodyuli ze-ADAS ezifuna amandla zivelisa ubushushu obukhulu; izinto ezifana nesiseko sesinyithi okanye iziseko zeseramikhi zingasetyenziswa.
- Ukuhlanganiswa Kwee-Multilayer: Iinkqubo ze-ADAS ezintsonkothileyo zihlala zifuna ii-PCB ezingamaleya ayi-8-12 ukuze zihambise amandla, umhlaba, kunye neeleya zesignali ngokufanelekileyo.
- Ulawulo lwe-EMI/EMC: Iindlela zokukhusela kunye nokubeka isiseko esifanelekileyo kubalulekile ukuthintela ukuphazamiseka kwesignali.
- Ukuthembeka Phantsi Kweemeko Ezinzima: Ii-PCB kufuneka zikwazi ukumelana nokungcangcazela, ukufuma, kunye nokuguquguquka kobushushu kwiindawo zeemoto.
Njengoko ukuqhuba ngokuzimela kunye nokuhamba ngobuchule kukhula, ii-ADAS PCB ziya ziphucuka kwaye zibalulekile. Ukukhetha iqabane elifanelekileyo loyilo lwe-PCB elinolwazi kwiibhodi zeemoto ezisebenza rhoqo kwaye ezinokuthembeka okuphezulu kubalulekile ukuze kuphumelele.
