Sensor khatello ea mafura bakeng sa Cadillac Buick Chevrolet 13500745

Ts'ebetso ena ea moralo le tlhahiso ea sensor ea khatello ha e le hantle ke ts'ebeliso e sebetsang ea theknoloji ea MEMS ( khutsufatso ea microelectromechanicalsystems, ke hore, micro-electromechanical system).

MEMS ke thekenoloji ea moeli oa lekholong la bo21 la lilemo e thehiloeng ho micro/nanotechnology, e e nolofalletsang ho qapa, ho sebetsa, ho etsa le ho laola thepa ea micro/nano. E ka kopanya likarolo tsa mochini, litsamaiso tsa optical, likarolo tsa ho khanna, litsamaiso tsa taolo ea elektroniki le lits'ebetso tsa ts'ebetso ea dijithale ho micro-system e le yuniti kaofela. MEMS ena ha e khone feela ho bokella, ho sebetsana le ho romela tlhahisoleseding kapa litaelo, empa hape ho nka liketso ka boikemelo kapa ho latela litaelo tsa ka ntle ho latela boitsebiso bo fumanoeng. E sebelisa mokhoa oa tlhahiso o kopanyang theknoloji ea microelectronics le theknoloji ea micromachining (ho kenyeletsoa silicon micromachining, silicon surface micromachining, LIGA le wafer bonding, joalo-joalo) ho etsa li-sensor tse fapa-fapaneng, li-actuator, bakhanni le li-microsystem tse nang le ts'ebetso e babatsehang le theko e tlaase. MEMS e totobatsa tšebeliso ea thekenoloji e tsoetseng pele ho hlokomela litsamaiso tse nyane le ho totobatsa bokhoni ba litsamaiso tse kopaneng.

Sensor ea khatello ke moemeli ea tloaelehileng oa theknoloji ea MEMS, 'me theknoloji e' ngoe e sebelisoang hangata ke MEMS gyroscope. Hona joale, bafani ba bangata ba tsamaiso ea EMS, ba kang BOSCH, DENSO, CONTI joalo-joalo, kaofela ba na le li-chips tsa bona tse inehetseng tse nang le mehaho e tšoanang. Melemo: kopanyo e phahameng, boholo ba sensor e nyane, boholo bo nyane ba sehokelo se nang le boholo bo nyane, ho bonolo ho hlophisa le ho kenya. Khatello ea chip ka hare ho sensor e kenngoa ka ho feletseng ka gel ea silica, e nang le mesebetsi ea ho hanyetsa kutu le ho hanyetsa ho sisinyeha, 'me e ntlafatsa haholo bophelo ba tšebeletso ea sensor. Tlhahiso e kholo ea bongata e na le litšenyehelo tse tlaase, chai e ngata le ts'ebetso e babatsehang.

Ntle le moo, bahlahisi ba bang ba li-sensor tsa khatello ea mali ba sebelisa li-chips tsa khatello e akaretsang, ebe ba kopanya li-circuits tsa peripheral joalo ka li-chips tsa khatello, li-circuits tsa ts'ireletso tsa EMC le li-PIN tsa likhokahano ka liboto tsa PCR. Joalokaha ho bontšitsoe setšoantšong sa 3, li-chips tsa khatello li kentsoe ka morao ho boto ea PCB, 'me PCB ke boto ea PCB e mahlakoreng a mabeli.

Mofuta ona oa sensor ea khatello o na le kopano e tlase le litšenyehelo tse phahameng tsa thepa. Ha ho na sephutheloana se tiisitsoeng ka ho feletseng ho PCB, 'me likarolo li kopantsoe ho PCB ka mokhoa oa setso oa soldering, e leng se lebisang kotsing ea ho hlahisa lihlahisoa. Sebakeng sa thothomelo e phahameng, mocheso o phahameng le mongobo o phahameng, PCB e lokela ho sireletsoa, ​​e nang le kotsi ea boleng bo phahameng.
