I-Automotive Flexible PCBs-16 Year Journey of Design&Prototype and Fabrication

Hlola ukuvela kweubuchwepheshe be-automotive flex PCB nomkhiqizi we-Capel, oneminyaka engu-16 yobuchwepheshe bokuklama, ukudweba kanye nokukhiqiza.. Ukubheka kabanzi ama-PCB anezingqimba eziyi-8 ze-HDI okwesibili okuqinile, okubhaliwe okunembayo, okuthuthukisiwe Inqubo yokukhiqiza nomoya wokuqamba ongakhathali kubonakala kulesi sihloko esibanzi.

Yethula:

Esikhathini sobuchwepheshe bezimoto obuphambili, isidingo sezinhlelo zikagesi ezithembekile, ezisebenza kahle kakhulu senyuke kakhulu. Amabhodi esekethe aphrintiwe e-Rigid-flex (ama-PCB) adlala indima ebalulekile ekuhlangabezaneni nalesi sidingo, ehlinzeka ngokuguquguquka okudingekayo, ukuqina kanye nokusebenza kahle kwesikhala kwezinhlelo zokusebenza zezimoto. Njengoba ineminyaka engu-16 yobungcweti ekwakhiweni kwe-PCB eguquguqukayo kwezimoto, i-prototyping kanye nokukhiqiza, indawo yaseCapel ihamba phambili kulokhu kuthuthukiswa kobuchwepheshe. Kulesi sihloko esibanzi, sizongena ezweni eliyinkimbinkimbi lama-PCB ezimoto aguquguqukayo, sihlole uhambo olumangalisayo lukaCapel kanye nentuthuko emangalisayo yezobuchwepheshe ebaqhubele esicongweni sokusungulwa kwe-PCB eguquguqukayo. Kusukela ekuqondeni inkimbinkimbi yama-PCB e-HDI anesendlalelo sesibili se-HDI, kuya ekubunjweni kwezinto ngokucophelela, ubukhulu obunembile nobuchwepheshe bokwelapha obuphezulu, sizodalula i-mosaic emangalisayo echaza amakhono ka-Capel kubuchwepheshe be-PCB obushintshashintshayo bezimoto.

Isahluko 1: Ukwembula ubunkimbinkimbi be-8-layer HDI ye-second order rigid-flex PCB

Ama-PCB aguqukayo ayizingxenye ezibalulekile kumasistimu ezimoto esimanje ezinhlobonhlobo zezinhlelo zokusebenza ezidinga ukwethembeka nokusebenza okuphakeme. I-PCB enezingqimba eziyisi-8 zesoftware eqinile yezinga lesibili le-HDI isetha izindinganiso ezintsha ngobunkimbinkimbi, edinga ukuhlanganiswa okuvumelanayo kobuchwepheshe obusezingeni eliphezulu kanye nobuciko bobuciko obucophelelayo. Onjiniyela be-Capel abanekhono baye bafunda ubuciko bokuklama nokukhiqiza lawa ma-PCB ayinkimbinkimbi, abonisa ubuchwepheshe obungenakuqhathaniswa ekwakhiweni kwe-stackup yesendlalelo, ngesakhiwo nokukhethwa kwezinto ezibonakalayo. Ngokuqonda okucacile kwezidingo ezishisayo, zemishini nezikagesi zezicelo zezimoto, i-Capel iqinisekisa ukuthi zonke izici zomklamo we-PCB zihlangabezana nezidingo eziqinile zemboni yezimoto.

Isahluko sesi-2: Ukunemba Kokwakheka Kwezinto kanye Nobuqotho Bobukhulu

Izinto ezisetshenziswa kuma-PCB ezimoto eziguquguqukayo zidlala indima ebalulekile ekunqumeni ukusebenza kwazo, ukwethembeka nokuphila isikhathi eside. Ukusebenzisa kukaCapel i-polyimide (PI), ithusi, izinto ezinamathelayo kanye ne-FR4 kuhlanganisa ingqikithi yokuqina nokusebenza. Into ngayinye ikhethwa ngokucophelela ukuze imelane nezimo zokusebenza ezinzima ezivame ezindaweni zezimoto, kuqinisekiswe ukuthi i-PCB eguquguqukayo iletha ukusebenza okuphakeme kuzo zonke izimo. Ukwengeza, ububanzi obunembile bomugqa, isikhala somugqa kanye nokucaciswa kokuqina kwebhodi kugqamisa ukuzibophezela okuqinile kuka-Capel ekunembeni kobukhulu nokungaguquguquki, okuyizici ezibalulekile zokuqinisekisa ukusebenza okufanele nokuhambisana ngaphakathi kwezinhlelo zezimoto.

Isahluko 3:Izinkimbinkimbi Zomklamo Wezimbobo kanye Nokulungiswa Komphezulu

Imiklamo eyinkimbinkimbi yezimbobo kuma-PCB avumelana nezimo ibalulekile ekuqinisekiseni ukuxhumana nokusebenza kwezingxenye ze-elekthronikhi. Ubungcweti bukaCapel ekuklameni nasekusebenziseni izimpumputhe, ukungcwatshwa, nokugcwaliswa ngokugcwaliswa kugcizelela ukuzibophezela kwabo ekuzuzeni ubuqotho besiginali nokusebenza kukagesi. Ngaphezu kwalokho, ubuchwepheshe bokucwiliswa kwegolide obungena-electroless nickel (ENIG) obunokwelashwa okungaphezulu kwe-2-3uin ultra-thin coating bubonisa ukuzibophezela kukaCapel ekuthuthukiseni ukwethembeka, ukuthengiselana kanye nekhwalithi iyonke yama-PCB aguquguqukayo okusebenza kwezimoto.

Isahluko 4:Ukuvula Izinqubo Ezithuthukile Zokukhiqiza Nokulawula Ukubekezelelana

Ukukhiqiza ama-PCB ezimoto aguquguqukayo kudinga ukuhlanganiswa okungenamthungo kwezinqubo ezithuthukile kanye nezinyathelo eziqinile zokulawula ikhwalithi. Isipiliyoni seminyaka engu-16 sikaCapel siholele emandleni okukhiqiza abonakala ngokunemba, ukwethembeka nokusebenza kahle. Inkampani ibambelela ekubekezeleni okuqinile, okunebanga lokubekezelelana elingu-±0.1mm, eligcizelela ukuzibophezela kwabo okungaguquki ekunembeni okungaguquki kanye nekhwalithi ngayo yonke i-PCB eguquguqukayo abayikhiqizayo. Kusukela ekubhobozeni kuya ekucwecweni, ukuthwebula izithombe kuye ekucwaseni nasekuhlanganiseni okokugcina, inqubo yokukhiqiza yaseCapel ihlanganisa ukuqamba okusha kwezobuchwepheshe kanye nokusebenza kahle kakhulu.

Isahluko 5 Ingqikithi yeminyaka eyi-16: ubungcweti, ubungcweti kanye nokusungula izinto ezintsha

Umlando wefektri yaseCapel weminyaka engu-16 njengomkhiqizi we-PCB wezimoto uwubufakazi bokuzibophezela kwabo okungantengantengi ekusebenzeni kahle, ukusungula izinto ezintsha kanye nokwaneliseka kwamakhasimende. Ubungcweti obuqoqiwe ekwakhiweni kwe-PCB okuguquguqukayo kwezimoto, ukwenza ama-prototyping kanye nokukhiqiza busebenza njengesibani sobuchwepheshe nekhono, kuqinisa isikhundla sabo njengomholi wemboni. Ukusebenzisana kwamakhono enqubo ephakeme ye-Capel, ubuchwepheshe obuthuthukisiwe nokuzibophezela ekuthuthukisweni okuqhubekayo kwenze inkampani yaba uzakwethu othembekile kuma-OEM ezimoto nabahlinzeki emhlabeni jikelele.

Isahluko 6: Isiphetho: Ikusasa lama-PCB aguquguqukayo ezimoto nomoya ka-Capel ongaguquki

Njengoba ubuchwepheshe bezimoto buqhubeka nokuthuthuka ngezinga elingakaze libonwe ngaphambili, indima yama-PCB avumelana nezimo iba yinto ebaluleke kakhulu. Njengoba ineminyaka engu-16 yobuchwepheshe, ifektri yaseCapel ihamba phambili kulokhu kuthuthukiswa kobuchwepheshe, iqhutshwa umoya ongapheli wokusungula izinto ezintsha, ukunemba kanye nokuzivumelanisa nezimo. Yonke inqubo kusukela ekuqanjweni kwedizayini kuya ekufaniseni nasekukhiqizeni okokugcina kubonisa ukuzibophezela kukaCapel okungaguquki ekuthuthukisweni kwezobuchwepheshe kanye nokwaneliseka kwamakhasimende. Njengoba imboni yezimoto iqhubekela phambili ekusaseni elibonakala ngokuzimela, ukuxhumana, kanye nokufakwa kukagesi, ubungcweti bukaCapel ngokungangabazeki buzoqhubeka nokubumba futhi buchaze kabusha umkhakha wobuchwepheshe be-PCB obuguquguqukayo bezimoto.

Konke kukhulunywe

Iminyaka engu-16 yokuhlangenwe nakho kukaCapel ekwakhiweni kwe-PCB eguquguqukayo kwezimoto, ukwenza i-prototyping kanye nokukhiqiza kubonakale kuyisiko lokuphumelela, ukusungula izinto ezintsha kanye nekhono. Ukuphatha kwabo inkimbinkimbi ye-PCB enezingqimba eziyisi-8 ze-HDI yezinga lesibili eliqinile, ukwakheka kwezinto ezibonakalayo, izinqubo ezithuthukisiwe zokukhiqiza nokuzibophezela okungantengantengi ekwanelisekeni kwamakhasimende kubenze umholi ongenakuqhathaniswa kubuchwepheshe be-PCB obuguquguqukayo bezimoto. Njengoba imboni yezimoto igxumela emikhawulweni emisha yokuqamba izinto ezintsha, ubuchwepheshe be-Capel buzoqhubeka nokuba yisisekelo esithembekile sentuthuko yezobuchwepheshe yesikhathi esizayo.
