Roj Siab Sensor Rau Cadillac Buick Chevrolet 13500745

Cov qauv tsim no thiab cov txheej txheem ntau lawm ntawm lub siab sensor yog qhov tseeb ntawm cov tswv yim siv tshuab (cov tsiaj ntawv luv ntawm micro-electromeChanical system).

Mems yog 21st caug xyoo Frontier ntawm micro / nanotechnology, uas ua rau nws tsim qauv, tsim thiab tswj cov khoom siv micro / nano. Nws tuaj yeem sib sau ua ke cov tshuab kho mob, kho qhov muag, hluav taws xob tswj hwm thiab digital tswj cov tshuab rau hauv ib pawg micro-system raws li tag nrho cov chaw. Daim ntawv no tsis tuaj yeem tsuas yog sau, txheej txheem thiab xa cov ntaub ntawv lossis cov lus qhia, tab sis kuj tseem coj lawv cov lus qhia sab nraud raws li cov ntaub ntawv tau. Nws siv cov txheej txheem tsim khoom sib xyaw ua ke ua ke rau microelectronics technology thiab micromaching Technacining, thiab lwm yam. Cov cai qhia txog kev siv cov thev naus laus zis los xyuas cov micro-systems thiab qhia txog lub peev xwm ntawm cov tshuab sib xyaw.

Lub siab ntsuas yog ib tus neeg sawv cev raug cai ntawm Mems Technology, thiab lwm cov kev cai mems uas feem ntau yog mems gyroscope. Tam sim no, ob peb tus neeg xa khoom EMS, xws li Bosch, Denso, Conti thiab lwm yam muaj cov chips nrog cov qauv zoo sib xws. Cov txiaj ntsig zoo: Kev sib koom ua ke, sensor me me, me me constor sensor loj nrog loj me me, yooj yim los npaj thiab nruab. Lub siab nti nyob rau hauv lub sensor yog tag encapsulated hauv silica gel, uas muaj cov haujlwm ntawm corrosion tsis kam thiab kev cai txhim kho lub neej kev pabcuam ntawm lub sensor. Loj-teev pawg ntau lawm muaj tus nqi qis, siab heev thiab ua tau zoo heev.

Ib qho ntxiv, qee cov tuam ntxhab ntawm kev nkag siab lub siab ntsuas siv cov ntxiab siab xws li cov chips ua ke, thiab tom qab ntawd cov chips ua ke, EMC tiv thaiv kev tiv thaiv cov kab ke thiab tus pin pins ntawm cov txuas los ntawm PV. Raws li muaj nyob hauv daim duab 3, cov chips siab tau teeb tsa nyob sab nraum qab ntawm PCB board, thiab PCB yog ob tog ncej PCB board.

Qhov kev ntsuas ntawm lub siab no muaj kev sib koom ua ke tsawg thiab cov khoom siv siab. There is no fully sealed package on PCB, and the parts are integrated on PCB by traditional soldering process, which leads to the risk of virtual soldering. Nyob rau hauv ib puag ncig kev co, siab kub thiab av noo, pcb yuav tsum muaj kev tiv thaiv, uas muaj kev pheej hmoo zoo.
