I-AutoNetworks Technologies
I-Abstract-Isidibanisi esilungelelanisa i-airbag yemoto ye-elektroniki
iiyunithi zokulawula (ECUs) zaphuhliswa kwaye zadluliselwa kubuninziisigaba sokuvelisa yiSumitomo Wiring Systems, Ltd. kunyeAutoNetworks Technologies, Ltd. ngo-2005.
Uqhagamshelo lokucofa-fit ludibaniso lombane olungathengiswangaitekhnoloji, esebenzisa amandla oqhagamshelwano omatshini owenziweyophakathi kwemingxunya kwibhodi yesekethe eprintiweyo (PCB) kunyeiitheminali ezinobubanzi obukhulu kancinci kunomngxuma wokuphumelaububanzi.
Le teknoloji iye yaqatshelwa ngokubanzi kutshanje njengomlinganiselongokuchasene "neMfuneko yasimahla" yemathiriyeli equkaizixhobo zombane/ze-elektroniki.
Ukusetyenziswa kobu buchwepheshe kwizixhumi zeemoto,kufuneka sithathele ingqalelo imeko engqongileyo enobuzazaiimeko ezifunekayo.
Ngenxa yoko, ikhonkco elicofa-lilingana kwii-ECU ze-airbag yemotoiphuhliswe ngempumelelo kwaye yaveliswa ngobuninzi ukusuka ku-2005.
Ngaphezu koko, ababhali baye baphuhlisa uhlobo olutsha lobunzimaukufakwa kwetoti kwiitheminali, ngaloo ndlela kuthintelwa ukukhuhlwa kwetotingexesha lokufakwa kwenkqubo, oko kunokubangela i-short-circuitkwiPCB.
Amagama angundoqo- Ii-ECU zemoto, ukuthembeka koQhagamshelwano, iTin enzima
UkuPlating, iLead-Free, Press-fit Connection.
INTSHAYELELO
A. Khokela iMfuneko yasimahla kunye noQhagamshelwano loCofa-lingene
Kukho utyekelo lwehlabathi lokuphelisa izinto eziyingozi
izixhobo ezivela kwizixhobo zombane/ze-elektroniki (umz. RoHSUmyalelo [1]).Ngokukodwa, ukuphuhliswa kwe-solder yamahhala ekhokelelangumba ophambili ongxamisekileyo kumashishini ombane/ombanekwihlabathi jikelele.
Kwelinye icala, kwindawo yeemoto ze-elektronikiiiyunithi zolawulo (ECUs), kukho umdla solderless press-fititekhnoloji yoqhagamshelo lokunyuswa kohlobo lofakelo lomngxumaiinxalenye, njengezihlanganisi, ezaphunyezwa ngaphambili ngu aukuhamba okanye inkqubo yokuthengiswa kwamaza.
Nangona le teknoloji iye yamkelwa ngokuqhelekileyokwindawo yezixhobo zonxibelelwano ngaphezulu kwezimbalwa zokugqibela
Kumashumi eminyaka, bekukho ulindelo olukhulu kwisicelo sabo kwiziqhagamshelo zeemoto, kutsha nje ngokuxhomekeke kumanyathelo alawula iimfuno zasimahla.
Uqhagamshelo lokucofa luhlobo lwetekhnoloji yoqhagamshelo lombane, esebenzisa amandla oqhagamshelwano ngoomatshini owenziwe phakathi kwemingxunya ekhoyo kwibhodi yesekethe eprintiweyo (PCB) kunye neetheminali ezinobubanzi obungaphezulu kancinane kunobubanzi bomngxuma wokuphumela, njengoko kubonisiwe kumfanekiso. .
Obu bugcisa bukwanalo noncedo olongezelelweyo (I)Akukho nkqubo yokufudumeza eyongezelelweyo yezixhobo ezixhonywe kumphezulu, (2)Akukho mfuneko yokusebenzisa iiplastiki ezikwaziyo ukumelana nobushushu kwizindlu ezidityanisiweyo, kuba inkqubo yofakelo lwetheminali (oko kukuthi uqhagamshelo lwe-Press-fit) lwenziwa ngo. Ubushushu begumbi buchazwe kwiTheyibhile I.
Usetyenziso olugunyazisiweyo olunelayisensi kuphela: Ithala leencwadi leYunivesithi yaseCornell.Ikhutshelwe ngoNovemba 11,2022 ngo-05:14:29 UTC ukusuka kwi-IEEE Xplore.Izithintelo ziyasebenza.
