Sensa yamafuta amafuta a Cadillac Buick Chevrolet 13500745

Kupanga ndi kupanga kachipangizo kamphamvu kameneka ndikugwiritsa ntchito ukadaulo wa MEMS (chidule cha microelectromechanicalsystems, ndiko kuti, micro-electromechanical system).

MEMS ndi teknoloji ya m'zaka za m'ma 2100 yochokera ku micro / nanotechnology, yomwe imathandiza kupanga, kukonza, kupanga ndi kulamulira zipangizo zazing'ono / nano. Ikhoza kuphatikiza zida zamakina, makina owoneka bwino, zida zoyendetsera, makina owongolera zamagetsi ndi makina opangira ma digito mu micro-system monga gawo lonse. MEMS iyi siingangotolera, kukonza ndi kutumiza zidziwitso kapena malangizo, komanso kuchitapo kanthu pawokha kapena molingana ndi malangizo akunja malinga ndi zomwe mwapeza. Amagwiritsa ntchito njira yopangira kuphatikiza ukadaulo wa ma microelectronics ndi ukadaulo wa micromachining (kuphatikiza silicon micromachining, silicon surface micromachining, LIGA ndi bonding wafer, etc.) kupanga masensa osiyanasiyana, ma actuators, madalaivala ndi ma microsystem okhala ndi magwiridwe antchito abwino komanso otsika mtengo. MEMS ikugogomezera kugwiritsa ntchito ukadaulo wapamwamba kuzindikira ma micro-system ndikuwunikira luso la machitidwe ophatikizika.

Pressure sensor ndiyoyimira ukadaulo wa MEMS, ndipo ukadaulo wina wa MEMS womwe umagwiritsidwa ntchito kwambiri ndi MEMS gyroscope. Pakalipano, ambiri ogulitsa machitidwe a EMS, monga BOSCH, DENSO, CONTI ndi zina zotero, onse ali ndi tchipisi tawo tomwe tili ndi zida zofanana. Ubwino: kuphatikiza kwakukulu, kukula kwa sensa yaying'ono, kachipangizo kakang'ono kolumikizira kachipangizo kakang'ono, kosavuta kukonza ndikuyika. Chip choponderezedwa mkati mwa sensa chimakutidwa kwathunthu mu silika gel, yomwe ili ndi ntchito za kukana dzimbiri ndi kukana kugwedezeka, ndipo imathandizira kwambiri moyo wautumiki wa sensa. Kupanga kwakukulu kumakhala ndi mtengo wotsika, zokolola zambiri komanso ntchito yabwino kwambiri.

Kuphatikiza apo, ena opanga ma sensor amphamvu omwe amadya amagwiritsa ntchito tchipisi tambiri, kenako amaphatikiza mabwalo ozungulira monga tchipisi champhamvu, mabwalo achitetezo a EMC ndi ma PIN olumikizira kudzera pama board a PCR. Monga momwe tawonetsera pa Chithunzi 3, tchipisi choponderezedwa chimayikidwa kumbuyo kwa bolodi la PCB, ndipo PCB ndi bolodi yapawiri ya PCB.

Sensa yamtunduwu imakhala ndi kuphatikizika kochepa komanso mtengo wapamwamba wazinthu. Palibe phukusi losindikizidwa kwathunthu pa PCB, ndipo magawowa amaphatikizidwa pa PCB ndi njira yachikhalidwe yogulitsira, zomwe zimatsogolera pachiwopsezo cha soldering pafupifupi. M'malo ogwedezeka kwambiri, kutentha kwambiri ndi chinyezi chachikulu, PCB iyenera kutetezedwa, yomwe ili ndi chiopsezo chapamwamba.
