Roj siab sensor rau Cadillac Buick Chevrolet 13500745

Qhov kev tsim thiab tsim cov txheej txheem ntawm lub siab sensor yog qhov ua tau zoo ntawm MEMS thev naus laus zis (lub ntsiab lus ntawm microelectromechanicalsystems, uas yog, micro-electromechanical system).

MEMS yog lub xyoo pua 21st frontier technology raws li micro / nanotechnology, uas ua rau nws tsim, txheej txheem, tsim thiab tswj micro / nano cov ntaub ntawv. Nws tuaj yeem koom ua ke cov khoom siv kho qhov muag, kho qhov muag, cov khoom siv tsav tsheb, cov tshuab hluav taws xob tswj hluav taws xob thiab cov tshuab ua digital rau hauv micro-system raws li tag nrho chav tsev. MEMS no tuaj yeem tsis tsuas yog sau, txheej txheem thiab xa cov ntaub ntawv lossis cov lus qhia, tab sis kuj tseem ua haujlwm ntawm tus kheej lossis raws li cov lus qhia sab nraud raws li cov ntaub ntawv tau txais. Nws siv cov txheej txheem tsim khoom ua ke nrog kev siv tshuab microelectronics thiab micromachining technology (xws li silicon micromachining, silicon deg micromachining, LIGA thiab wafer bonding, thiab lwm yam) los tsim ntau yam sensors, actuators, tsav tsheb thiab microsystems nrog kev ua tau zoo thiab tus nqi qis. MEMS hais txog kev siv thev naus laus zis kom paub txog micro-systems thiab qhia txog lub peev xwm ntawm kev sib xyaw ua ke.

Lub siab sensor yog tus neeg sawv cev ntawm MEMS thev naus laus zis, thiab lwm yam siv MEMS tshuab yog MEMS gyroscope. Tam sim no, ntau tus neeg xa khoom EMS loj, xws li BOSCH, DENSO, CONTI thiab lwm yam, txhua tus muaj lawv tus kheej cov chips nrog cov qauv zoo sib xws. Qhov zoo: kev sib koom ua ke siab, me me sensor loj, me me connector sensor loj nrog me me, yooj yim rau kev npaj thiab nruab. Lub siab nti nyob rau hauv lub sensor yog tag nrho encapsulated nyob rau hauv silica gel, uas muaj lub zog ntawm corrosion kuj thiab kev co kuj, thiab zoo heev txhim kho lub neej kev pab cuam ntawm lub sensor. Loj-loj ntau lawm muaj tus nqi qis, siab yield thiab ua tau zoo heev.

Tsis tas li ntawd, qee cov tuam txhab tsim khoom siv cov khoom siv siab siv cov chips dav dav, thiab tom qab ntawd sib xyaw cov khoom siv hluav taws xob xws li cov chips siab, EMC tiv thaiv circuits thiab PIN pins ntawm cov khoom sib txuas los ntawm PCR boards. Raws li pom hauv daim duab 3, cov chips siab tau nruab rau sab nraum qab ntawm PCB pawg thawj coj saib, thiab PCB yog ob sab PCB board.

Hom kev ntsuas siab no muaj kev sib koom ua ke tsawg thiab cov khoom siv siab. Tsis muaj tag nrho cov ntim ntim ntawm PCB, thiab cov khoom sib xyaw ua ke ntawm PCB los ntawm cov txheej txheem soldering ib txwm ua, uas ua rau muaj kev pheej hmoo ntawm kev siv tshuab virtual. Nyob rau hauv ib puag ncig ntawm kev vibration siab, kub thiab av noo siab, PCB yuav tsum tau tiv thaiv, uas muaj kev pheej hmoo zoo.
