Inzwa yokucindezela kwamafutha yeCadillac Buick Chevrolet 13500745

Le nqubo yokuklama nokukhiqiza inzwa yokucindezela empeleni iwukusetshenziswa okusebenzayo kobuchwepheshe be-MEMS (isifinyezo se-microelectromechanicalsystems, okungukuthi, i-micro-electromechanical system).

I-MEMS ubuchwepheshe obusemngceleni wekhulu lama-21 obusekelwe ku-micro/nanotechnology, obuyenza ikwazi ukuklama, ukucubungula, ukukhiqiza nokulawula izinto ezincane/nano. Ingakwazi ukuhlanganisa izingxenye zemishini, amasistimu okubona, izingxenye zokushayela, amasistimu okulawula ama-elekthronikhi kanye nezinhlelo zokucutshungulwa kwedijithali zibe i-micro-system njengeyunithi iyonke. Le MEMS ayikwazi ukuqoqa kuphela, icubungule futhi ithumele imininingwane noma imiyalelo, kodwa futhi ithatha izinyathelo ngokuzimele noma ngokwemiyalelo yangaphandle ngokolwazi olutholiwe. Isebenzisa inqubo yokukhiqiza ehlanganisa ubuchwepheshe be-microelectronics kanye nobuchwepheshe be-micromachining (okuhlanganisa i-silicon micromachining, i-silicon surface micromachining, i-LIGA kanye ne-wafer bonding, njll.) ukwenza izinzwa ezihlukahlukene, ama-actuator, abashayeli nama-microsystems asebenza kahle kakhulu kanye nenani eliphansi. I-MEMS igcizelela ukusetshenziswa kobuchwepheshe obuthuthukisiwe ukuze kutholakale amasistimu amancane futhi igqamisa ikhono lezinhlelo ezididiyelwe.

Inzwa yokucindezela ingummeleli ojwayelekile wobuchwepheshe be-MEMS, futhi obunye ubuchwepheshe be-MEMS obuvame ukusetshenziswa yi-MEMS gyroscope. Njengamanje, abahlinzeki abaningana abakhulu besistimu ye-EMS, njenge-BOSCH, i-DENSO, i-CONTI njalonjalo, bonke banama-chips abo azinikezele anezakhiwo ezifanayo. Izinzuzo: ukuhlanganiswa okuphezulu, usayizi wenzwa encane, usayizi omncane wesixhumi esinosayizi omncane, kulula ukuhlela nokufaka. I-chip pressure ngaphakathi kwenzwa ifakwe ngokuphelele kujeli ye-silica, enemisebenzi yokumelana nokugqwala nokumelana nokudlidliza, futhi ithuthukisa kakhulu impilo yesevisi yenzwa. Ukukhiqizwa kwenani elikhulu kunezindleko eziphansi, isivuno esiphezulu nokusebenza okuhle kakhulu.

Ngaphezu kwalokho, abanye abakhiqizi bezinzwa zengcindezi yokwamukela basebenzisa ama-chips okucindezela okuvamile, bese behlanganisa amasekhethi aseduze njengama-press chips, amasekhethi okuvikela e-EMC namaphinikhodi we-PIN wezixhumi ngamabhodi e-PCR. Njengoba kukhonjisiwe kuMfanekiso 3, ama-chips okucindezela afakwa ngemuva kwebhodi le-PCB, futhi i-PCB iyibhodi le-PCB elinamacala amabili.

Lolu hlobo lwenzwa yokucindezela lunokuhlanganiswa okuphansi kanye nezindleko eziphezulu zempahla. Alikho iphakheji elivalwe ngokugcwele ku-PCB, futhi izingxenye zihlanganiswa ku-PCB ngenqubo yendabuko yokuhlanganisa, okuholela engcupheni yokudayiswa okubonakalayo. Endaweni yokudlidliza okuphezulu, izinga lokushisa eliphezulu kanye nomswakama ophezulu, i-PCB kufanele ivikelwe, enobungozi bekhwalithi ephezulu.
