MEMS​

I-MEMS, emele i-MicroElectroMechanical Systems ama-micro-scale we-chip amancane akhiwe izingxenye eziphakathi kwe-micrometer engu-1 kuya ku-100 ngosayizi (i-micrometer iyingxenye eyodwa yesigidi semitha) kanye namadivayisi we-MEMS ngokuvamile aqala ngosayizi ukusuka ku-20 micrometers_cc781905-5cde-3194-bb3bd5588-bb3b_138 (izigidi ezingama-20 zemitha) ukuya kumilimitha. Imishini eminingi ye-MEMS ingamakhulu ambalwa ama-microns ngaphesheya. Imvamisa iqukethe iyunithi emaphakathi ecubungula idatha, i-microprocessor kanye nezingxenye ezimbalwa ezisebenzisana ngaphandle njengezinzwa ezincane. Ezikalini ezincane ezinjalo, imithetho ye-classical physics ayisebenzi ngaso sonke isikhathi. Ngenxa yobukhulu bendawo ye-MEMS nesilinganiso sevolumu, imiphumela engaphezulu efana ne-electrostatics nokumanzisa ilawula imiphumela yevolumu efana ne-inertia noma isisindo sokushisa. Ngakho-ke, ukuklama nokuthuthukiswa kwe-MEMS kudinga ulwazi oluthile kulo mkhakha kanye nesofthiwe ethile ecabangela le mithetho ye-non-classical physics.

​

I-MEMS yaba usizo ikakhulukazi phakathi namashumi ambalwa eminyaka adlule ngemva kokuba ingakhiwa kusetshenziswa ubuchwepheshe bokwenziwa kwemishini ye-semiconductor elungisiwe, eyayivame ukusetshenziselwa ukwenza izinto zikagesi. Lokhu kufaka phakathi ukubumba nokucwenga, ukunamathisela okumanzi (KOH, TMAH) kanye ne-etching eyomile (RIE ne-DRIE), i-electric discharge machining (EDM), ukufakwa kwefilimu emincane kanye nobunye ubuchwepheshe obukwazi ukukhiqiza amadivaysi amancane kakhulu.

​

Uma unomqondo omusha we-MEMS kodwa ungenawo amathuluzi okuklama akhethekile kanye/noma ubuchwepheshe obufanele, singakusiza. Ngemva kokuklama, ukuthuthukiswa kanye nokwenza singathuthukisa ihadiwe yokuhlola eyenziwe ngokwezifiso kanye nesofthiwe yomkhiqizo wakho we-MEMS. Sisebenza nenqwaba yabasunguli abakhethekile ekwenziweni kwe-MEMS. Womabili amawafa angu-150mm no-200mm acutshungulwa ngaphansi kwe-ISO/TS 16949 kanye ne-ISO 14001 ebhalisiwe kanye nezimo ezithobelayo ze-RoHS. Siyakwazi ukwenza ucwaningo oluphambili, ukuklama, ukuthuthukiswa, ukuhlola, iziqu, i-prototyping kanye nokukhiqizwa kwezentengiselwano eziphezulu. Amanye amadivaysi e-MEMS adumile onjiniyela bethu abanolwazi kuwo afaka:

Izinzwa ezincane ze-MEMS nama-actuator anikeze amandla ukusebenza okusha kumafoni ahlakaniphile, amaphilisi, izimoto, ama-projektha...njll. futhi zibalulekile ku-inthanethi Yezinto (IoT). Ngakolunye uhlangothi, i-MEMS yethula izinselele ezikhethekile zobunjiniyela, okuhlanganisa izinqubo zokwenziwa ezingajwayelekile, ukusebenzisana kwe-multi-physics, ukuhlanganiswa nama-IC, kanye nezidingo zokupakisha ze-hermetic zangokwezifiso. Ngaphandle kwenkundla yokuklama ethize ye-MEMS, ngokuvamile kuthatha iminyaka eminingi ukuletha umkhiqizo we-MEMS ukumaketha. Sisebenzisa amathuluzi athuthukile ukuklama nokuthuthukisa i-MEMS. I-Tanner MEMS Design isenza sikwazi ukuklama kwe-3D MEMS nokusekelwa kokwenziwa endaweni eyodwa ebumbene, futhi yenza kube lula ukuhlanganisa amadivayisi we-MEMS namasekhethi okucubungula ama-analog/amasignali axutshiwe ku-IC efanayo. Ithuthukisa ukwenziwa kwemishini ye-MEMS ngokusebenzisa ukuhlaziya kwemishini, okushisayo, kwe-acoustic, kukagesi, kwe-electrostatic, kazibuthe noketshezi. Amanye amathuluzi esofthiwe avela ku-Coventor asinika izinkundla ezinamandla zokuklama kwe-MEMS, ukulingisa, ukuqinisekiswa kanye nokumodela kwenqubo. Inkundla ye-Coventor ibhekana nezinselele zobunjiniyela eziqondene ne-MEMS ezifana nokusebenzisana kwe-multi-physics, ukuhlukahluka kwezinqubo, ukuhlanganiswa kwe-MEMS+IC, ukusebenzisana kwephakheji kwe-MEMS. Onjiniyela bethu be-MEMS bayakwazi ukwenza imodeli futhi balingise ukuziphatha kwedivayisi nokusebenzisana ngaphambi kokuzibophezela ekwenziweni kwangempela, futhi ngamahora noma izinsuku, bangakwazi ukwenza imodeli noma balingise imithelela ebingase ithathe izinyanga zokwakha nokuhlola entanjeni. Amanye amathuluzi athuthukile abaklami bethu be-MEMS abawasebenzisayo yilawa alandelayo.

I-MICROFLUIDICS

Idizayini yethu yedivayisi ye-microfluidics kanye nemisebenzi yokuthuthukisa ihloselwe ukwenziwa kwamadivayisi namasistimu lapho kuphathwa khona uketshezi oluncane. Sinekhono lokukudizayinela amadivaysi e-microfluidic futhi sikunikeze i-prototyping & micromanufacturing ngokwezifiso ezenzelwe izinhlelo zakho zokusebenza. Izibonelo zamadivayisi e-microfluidic amadivaysi e-micro-propulsion, amasistimu e-lab-on-a-chip, ama-micro-thermal devices, ama-inkjet printheads nokuningi. Kuma-microfluidics kufanele sibhekane nokulawula okunembayo kanye nokuxhaphaza uketshezi oluphoqelwe ezifundeni zamamilimitha angaphansi. Uketshezi luyanyakaziswa, luxutshwe, luhlukaniswe futhi lucutshungulwe. Kuzinhlelo ze-microfluidic uketshezi luyanyakaziswa futhi lulawuleke ngokusebenzisa amaphampu amancane amancane nama-microvalve nokunye okunjalo noma ngokungenzi lutho kusetshenziswa amandla e-capillary. Ngezinhlelo ze-lab-on-a-chip, izinqubo ezivame ukwenziwa elebhu zenziwa zibe mincane ku-chip eyodwa ukuze kuthuthukiswe ukusebenza kahle nokuhamba kanye nokunciphisa amasampula namavolumu ezinto ezisebenzayo.

Ezinye izinhlelo zokusebenza ezinkulu zamadivayisi nezinhlelo ze-microfluidic yilezi:

I-AGS-Engineering iphinde inikeze ukubonisana, ukuklama kanye nokuthuthukiswa komkhiqizo kumasistimu nemikhiqizo yegesi neyoketshezi, ngezikali ezincane. Sisebenzisa amathuluzi athuthukile e-Computational Fluid Dynamics (CFD) kanye nokuhlola elabhorethri ukuze siqonde futhi sibone ngeso lengqondo ukuziphatha kokugeleza okuyinkimbinkimbi. Onjiniyela bethu be-microfluidics basebenzise amathuluzi e-CFD kanye ne-micrscopy ukuze baveze izenzakalo zokuthutha uketshezi oluncane emithonjeni yezindaba evulekile. Siphinde sibe nokubambisana okuseduze nabasunguli bokucwaninga, ukuklama. Thuthukisa futhi unikeze izingxenye ze-microfluidic & bioMEMS. Singakusiza ukuthi udizayine futhi uzenzele awakho ama-microfluidic chips. Ithimba lethu elinolwazi lokuklama ama-chip lingakusiza ngokuklama, ukwenza i-prototyping kanye nokwakhiwa kweziqalo ezincane nenani levolumu lama-microfluidic chips ohlelo lwakho lokusebenza oluthile. Ukuqala ngamadivayisi kumapulasitiki kuyanconywa ukuthi kuhlolwe ngokushesha njengoba kuthatha isikhathi esincane nezindleko zokwenziwa uma kuqhathaniswa namadivayisi aku-PDMS. Singakha amaphethini eMicrofluidic kumapulasitiki afana ne-PMMA, COC. Singenza i-photolithography elandelwa yi-soft lithography ukuze sakhe amaphethini e-microfluidic ku-PDMS. Sikhiqiza izingcweti zensimbi, singamaphethini okugaya kwi-Brass ne-Aluminium. Ukwenziwa kwedivayisi ku-PDMS nokwenza amaphethini kumapulasitiki nezinsimbi kungaqedwa phakathi namaviki ambalwa. Singahlinzeka ngezixhumi zamaphethini enziwe kumapulasitiki uma sicelwa njengezixhumi zembobo ezihambisana nosayizi wembobo ongu-1mm kanye nokufanele ukuxhuma amashubhu e-capillary micron angu-360 e-PEEK. I-mini luer yesilisa enephini lensimbi ingahlinzekwa ukuze kuxhunywe ishubhu ye-tygon engu-0.5 mm ububanzi bangaphakathi phakathi kwamachweba oketshezi kanye nephampu yesirinji. Amanzi okugcina amanzi anomthamo ongu-100 μl. ingahlinzekwa futhi. Uma usuvele unomklamo, ungawuthumela ngefomethi ye-Autocad, .dwg noma .dxf.
