6.1 I-Miniaturization kunye nokunyuka kobunzima: Enye yeendlela ezibalulekileyo kwii-PCB ze-automotive electronics kukutyhala okuqhubekayo kwe-miniaturization kunye nobunzima.Njengoko izithuthi zihambela phambili ngakumbi kwaye zixhotyiswe ngeenkqubo ezahlukeneyo zombane, imfuno yeePCB ezincinci kunye nezixineneyo iyaqhubeka nokukhula.Le miniaturization ibeka imingeni ekubekweni kwecandelo, umzila, ukuchithwa kwe-thermal, kunye nokuthembeka.Abaqulunqi be-PCB kunye nabavelisi kufuneka bafumane izisombululo ezintsha zokujongana nemiba yefomu ecuthekayo ngelixa igcina ukusebenza kwe-PCB kunye nokuqina.
6.2 Ukudityaniswa kobuchwepheshe obuphambili: Ishishini leemoto libona inkqubela ekhawulezileyo kwezobuchwepheshe, kubandakanywa ukudityaniswa kobuchwepheshe obuphambili kwizithuthi.IiPCB zidlala indima ephambili ekwenzeni obu buchwepheshe busebenze, njengeenkqubo zokuncedisa umqhubi (ADAS), iinkqubo zezithuthi zombane, izisombululo zoqhagamshelwano kunye neempawu zokuqhuba ezizimeleyo.Ezi teknoloji ziphambili zifuna ii-PCB ezinokuxhasa isantya esiphezulu, ukuphatha idatha enzima, kunye nokuqinisekisa unxibelelwano oluthembekileyo phakathi kwamacandelo kunye neenkqubo ezahlukeneyo.Ukuyila kunye nokwenza iiPCBs ezihlangabezana nezi mfuno ngumngeni omkhulu kushishino.
6.3 Inkqubo yokwenziwa kwemveliso kufuneka iqiniswe: Njengoko imfuno yee-PCB ze-automotive electronics iqhubeka nokukhula, abavelisi bajongene nomceli mngeni wokuphucula iinkqubo zokwenziwa kwemveliso ukuhlangabezana nomthamo ophezulu wemveliso ngelixa begcina imigangatho yomgangatho ophezulu.Ukulungelelanisa iinkqubo zemveliso, ukuphucula ukusebenza kakuhle, ukunciphisa amaxesha okujikeleza kunye nokunciphisa iziphene ziindawo apho abavelisi kufuneka bagxininise imizamo yabo.Ukusetyenziswa kobuchwephesha bokuvelisa obuphezulu, obufana nendibano ezenzekelayo, iirobhothi kunye neenkqubo zokuhlola eziphambili, kunceda ukuphucula ukusebenza kakuhle kunye nokuchaneka kwenkqubo yokuvelisa.Ukwamkela i-Industry 4.0 iikhonsepthi ezifana ne-Intanethi yeZinto (IoT) kunye nohlalutyo lwedatha lunokubonelela ngengqiqo ebalulekileyo ekuphuculeni inkqubo kunye nokugcinwa kwangaphambili, ngaloo ndlela ukwandisa imveliso kunye nemveliso.
7.Umvelisi owaziwayo webhodi yesekethe yeemoto:
I-Shenzhen Capel Technology Co., Ltd. yaseka umzi-mveliso webhodi yesekethe ngo-2009 kwaye yaqala ukuphuhlisa nokwenza iibhodi zeesekethe eziguquguqukayo, iibhodi zemihlanganisela, kunye neebhodi eziqinileyo.Kule minyaka ili-15 idlulileyo, sigqibe ngempumelelo amashumi amawaka eeprojekthi zebhodi yesekethe yeemoto kubathengi, saqokelela amava atyebileyo kushishino lweemoto, saza sanika abathengi izisombululo ezikhuselekileyo nezithembekileyo.Ubunjineli obuchwephesha baseCapel kunye namaqela e-R&D ziingcali onokuzithemba!
Isishwankathelo,Inkqubo yokwenziwa kwePCB yeemoto zombane ngumsebenzi onzima nocokisekileyo ofuna intsebenziswano esondeleyo phakathi kweenjineli, abayili, kunye nabavelisi.Iimfuno ezingqongqo zeshishini leemoto zifuna umgangatho ophezulu, othembekileyo kunye neePCB ezikhuselekileyo.Njengoko itekhnoloji iqhubeka nokuhambela phambili, iiPCB ze-elektroniki zemoto ziya kufuna ukuhlangabezana nemfuno ekhulayo yemisebenzi entsonkothileyo kunye nentsonkothileyo.Ukuhlala uphambi kweli candelo livela ngokukhawuleza, abavelisi bePCB kufuneka bahambisane neendlela zamva nje.Kufuneka batyale imali kwiinkqubo zokuvelisa eziphambili kunye nezixhobo zokuqinisekisa ukuveliswa kweePCB eziphezulu.Ukusebenzisa izenzo ezikumgangatho ophezulu akuphuculi nje kuphela amava okuqhuba, kodwa kukwabeka phambili ukhuseleko nokuchaneka.
