Mu dziko la kupanga zinthu mwanzeru kwambiri—kumene kulekerera kumachepa pansi pa ma microns 5 ndipo kutsirizika kwa pamwamba kumafikira pa mtundu wa kuwala—zida zomwe timadalira ziyenera kusintha kupitirira miyambo. Kwa zaka zambiri, chitsulo ndi granite zinali ngati benchi ya metrology. Koma pamene mafakitale monga zida za semiconductor, aerospace optics, ndi zida zazing'ono zachipatala zikulowa m'malo omwe ngakhale kutentha kapena kuwonongeka kwa microscopic kumabweretsa cholakwika chosavomerezeka, gulu latsopano la zida zowunikira likubwera: zomwe sizinapangidwe ndi chitsulo kapena miyala, koma kuchokera ku zoumba zapamwamba zaukadaulo.
Ku ZHHIMG, tapita patsogolo kuposa kungoperekaWolamulira Wowongoka wa Ceramickapena zinthu za Ceramic Square Ruler. Tikusintha momwe m'mphepete wowongoka ungakhalire—pophatikiza zipangizo za ceramic zokhazikika kwambiri ndi kapangidwe kamakono, kuphatikiza ruler yathu yatsopano ya Custom Ceramic air floating, yankho lomwe limachotsa kukhudzana kwa makina konse pamene likupereka kubwerezabwereza kwa nanometer.
Chifukwa chiyani ndi zinthu zadothi? Yankho limayambira pa mulingo wa mamolekyulu. Mosiyana ndi chitsulo—chomwe chimakula kwambiri ndi kutentha—kapena granite—chomwe, ngakhale chili chokhazikika, chimakhalabe ndi mapokoso komanso chosiyana—zinthu zadothi zopangidwa monga zirconia-toughened alumina (ZTA) ndi silicon nitride zimapereka mapokoso osapitirira zero, kuuma kwapadera (1400–1800 HV), ndi ma coefficients okulitsa kutentha otsika ngati 3–4 µm/m·°C. Izi zikutanthauza kuti Ceramic Straight Edge yochokera ku ZHHIMG imasunga mawonekedwe ake pakusintha kwa kutentha komwe kungasokoneze zida zachikhalidwe ndi ma microns angapo.
Koma zinthu zokha sizikwanira. Chomwe chimasiyanitsa ma ruler athu a ceramic ndi kulondola kwa kapangidwe kawo. Pogwiritsa ntchito kugaya diamondi, kupukuta kwa sub-aperture, ndi kutsimikizira kwa laser interferometric mu ISO Class 5 cleanrooms, timapeza kulekerera kowongoka kuposa 0.8 µm kuposa 500 mm—komwe kwatsimikiziridwa osati pongoperekedwa kokha, komanso kolembedwa m'malipoti athunthu owunikira omwe angatsatire miyezo ya NIST ndi PTB.Wolamulira wa Ceramic Squareamayesedwa poyimirira kudzera mu electronic autocollimation, kuonetsetsa kuti ma angles akugwiritsidwa ntchito mkati mwa 1 arc-second (≈0.5 µm deviation pa 100 mm).
Izi sizinthu zongoganizira chabe. Ndi zenizeni zogwirira ntchito kwa makasitomala omwe sangathenso kuvomereza. Kampani yotsogola yogulitsa zinthu za EUV tsopano ikugwiritsa ntchito Ceramic Straight Ruler yathu pongolumikiza mafelemu othandizira magalasi. "Ma ruler achitsulo amapotoka nthawi yayitali," katswiri wawo wamkulu wa metro adatiuza. "Granite yatola tinthu tating'onoting'ono. Mtundu wa ceramic? Wakhala wokhazikika kwa miyezi 18 - palibe chifukwa chokonzanso."
Komabe, ngakhale mawonekedwe abwino kwambiri amatha kusokonekera chifukwa chokhudza. Kokani rula pamwamba, ndipo mungakhale pachiwopsezo cha kukanda pang'ono, kusokonezeka kwa filimu yamafuta, kapena kusintha kwa elastic - makamaka pazitsulo zofewa kapena ma optics opukutidwa. Apa ndi pomwe luso la ZHHIMG limapita patsogolo ndi rula loyandama la Custom Ceramic air.
Iyi si njira yolunjika ya ceramic yokha yokhala ndi mabowo obowoledwa. Ndi njira yopangidwa bwino kwambiri yozungulira mpweya, yopangidwa pogwiritsa ntchito mphamvu zamagetsi kuti ipereke mpweya wofanana, wozungulira kutalika konse kwa rula. Ikakakamizidwa ndi mpweya woyera, wouma (kapena nayitrogeni m'malo ovuta), rula imayandama ma microns 5-10 pamwamba pa chogwirira ntchito—kuchotsa kukhudzana kwakuthupi pamene ikusunga kulinganiza bwino. Zotsatira zake? Muyeso weniweni wosakhudzana ndi kukhazikika, kulunjika, kapena kutsimikizira kutalika kwa sitepe, ndi kubwerezabwereza mpaka ± 0.2 µm.
Labu ina ya quantum computing ku Switzerland tsopano ikugwiritsa ntchito rula loyandama la mpweya la 600-mm Custom Ceramic kuti ione zonyamulira ma chips a superconducting. "Kukhudzana kulikonse—ngakhale ndi cholembera chofewa—kumayambitsa kupsinjika komwe kumasintha magwiridwe antchito a qubit," mainjiniya awo anafotokoza. "Rula loyandama la mpweya limatipatsa chidziwitso chomwe timafunikira popanda kukhudza gawolo. Lakhala lofunika kwambiri pa ntchito."
Chomwe chimapangitsa izi kukhala zotheka ndi kuphatikiza kwapadera kwa ZHHIMG kwa sayansi ya zinthu, makina olondola, ndi ukatswiri wa metrology. Ngakhale ogulitsa ambiri amaona kuti zinthu zadothi ndi zinthu zopangidwa ndi ceramics ndi zinthu zina zomangira, timazikonza ngati zinthu zoyezera. Mapangidwe athu a Ceramic Square Ruler amaphatikizapo m'mbali zopindika kuti zisawonongeke, kumbuyo komalizidwa ndi matte kuti kuchepetse kuwala komwe kumawunikira, komanso zizindikiro zodziyimira zokha zamachitidwe owonera okha. Pa ntchito zoyeretsa m'chipinda, malo amapukutidwa mpaka Ra < 0.02 µm kuti achepetse kumatirira kwa tinthu.
Ndipo chifukwa chakuti ntchito iliyonse ndi yosiyana, sitikhulupirira kuti zonse zimagwirizana ndi kukula komweko. Mukufuna Ceramic Straight Edge yokhala ndi njira zotsukira zolumikizira kuti zigwire ma wafers owonda panthawi yowunikira? Tapanga. Mukufunawolamulira wa sikweyandi mabowo olowera omwe ali pafupi ndi nsonga yanu ya probe ya CMM? Mwamaliza. Mukufuna rula yoyandama ya Ceramic yokhala ndi masensa opanikizika ophatikizidwa komanso mayankho a digito? Zimenezo zili kale mu kuyesa kwa beta ndi kasitomala wa Tier-1 aerospace.
Kuzindikirika kwa makampani kwatsatira. Mu 2025 Global Advanced Metrology Review, ZHHIMG idatchulidwa kuti ndi kampani yokhayo yomwe imapereka banja lonse la zida zovomerezeka za ceramic—kuphatikizapo mitundu yoyandama—yokhala ndi kutsimikizika kwathunthu kwa geometric ndi kutsata kwa digito. Koma chofunika kwambiri, kugwiritsa ntchito kukuchulukirachulukira: maoda athu opitilira 60% a ceramic ruler tsopano akuchokera kumakampani omwe kale ankaona zida zotere kukhala “zopitirira muyeso”—mpaka atayesa kusiyana kwake.
Kampani yatsopano ya zida zamankhwala yomwe imapanga ma implants a mitsempha yasintha kuchoka pa chitsulo kupita ku Ceramic Square Ruler yathu ndipo yawona kuti phindu lawo loyamba lapita patsogolo ndi 22%. "Sikweya yakaleyo idasiya ma micro-gouges pa titanium housings," adatero manejala wawo wa QA. "Sitinazindikire ngakhale mpaka titasintha. Tsopano, gawo lililonse limadutsa macheke owoneka ndi maso pa kuyesa koyamba."
Kotero pamene mukuyang'ana kusintha kwanu kotsatira kwa metrology, dzifunseni kuti: Kodi straight edge yanga yomwe ndili nayo panopa ikuwonjezera kusatsimikizika—kapena kukuchotsa?
Ngati njira yanu ikugwira ntchito bwino kwambiri, yankho lake lingakhale mu zinthu zadothi—osati ngati chinthu chatsopano, koma ngati chofunikira. Ku ZHHIMG, sitipanga zida za Ceramic Straight Ruler, Ceramic Square Ruler, kapena Ceramic Straight Edge zokha. Timapanga chidaliro mu micron iliyonse.
