Chogwiritsira ntchito chimagwiritsidwa ntchito mu chuck, chokwera pa gulu kapena kuchitidwa pakati pa malo ndi kuzungulira, pamene chida chodula (kawirikawiri chida cha mfundo imodzi) chimadyetsedwa mozungulira kapena kumapeto kwake kapena kumaso. pamphepete mwa workpiece);kutembenuka kwa tapered (kupanga taper);kutembenuka kwapang'onopang'ono (kutembenuza ma diameter a kukula kosiyana pa ntchito imodzi);kugwedeza (kugwedeza m'mphepete kapena phewa);kuyang'ana (kudula mapeto);Kutembenuza ulusi (nthawi zambiri ulusi wakunja, komanso ukhoza kukhala ulusi wamkati);roughing (kuchotsa zitsulo zambiri);ndi kumaliza (kumeta ubweya wopepuka kumapeto) . Pa lathes, malo otembenuzira, makina opangira chuck, makina opangira ma screw ndi makina ofanana.
Monga luso lopangira zitsulo zachitsulo, photochemical etching (PCE) imatha kupirira zolimba, ndizobwerezabwereza, ndipo nthawi zambiri ndi teknoloji yokhayo yomwe ingathe kupanga zopangira zitsulo zolondola, Zimafunika kulondola kwambiri ndipo nthawi zambiri zimakhala safe.key. mapulogalamu.
Akatswiri opanga mapangidwe amasankha PCE ngati njira yawo yopangira zitsulo, ndikofunikira kuti amvetsetse osati kusinthasintha kwake kokha komanso mbali zenizeni zaukadaulo zomwe zingakhudze (ndipo nthawi zambiri zimawonjezera) kapangidwe kazinthu. yamikirani kuti mupindule kwambiri ndi PCE ndikufanizira ndondomekoyi ndi njira zina zopangira zitsulo.
PCE ili ndi zikhumbo zambiri zomwe zimalimbikitsa luso komanso "kukulitsa malire mwa kuphatikizapo zovuta za mankhwala, zowonjezera, zamakono komanso zogwira mtima". Ndizofunika kwambiri kuti akatswiri opanga mapangidwe akwaniritse zonse zomwe angathe, ndipo micrometal (kuphatikizapo HP Etch ndi Etchform) imalimbikitsa makasitomala ake. kuwatenga ngati othandizana nawo pakupanga zinthu - osati opanga ma contract ang'onoang'ono - kulola ma OEMs kukhathamiritsa kuchulukiraku koyambirira kwa gawo lopanga.Kuthekera komwe njira zogwirira ntchito zachitsulo zingapereke.
Kukula kwa Zitsulo ndi Mapepala: Lithography ingagwiritsidwe ntchito pazitsulo zazitsulo zamitundu yosiyanasiyana, masukulu, kutentha ndi kukula kwa pepala. kuthekera.
Mwachitsanzo, pogwira ntchito ndi Etching Group ya micrometal, ndondomekoyi ingagwiritsidwe ntchito pazitsulo zopyapyala zochokera ku 10 microns mpaka 2000 microns (0.010 mm mpaka 2.00 mm), ndi mapepala apamwamba / chigawo chachikulu cha 600 mm x 800 mm. zikuphatikizapo zitsulo ndi zitsulo zosapanga dzimbiri, faifi tambala ndi faifi tambala, zitsulo zamkuwa ndi mkuwa, malata, siliva, golidi, molybdenum, aluminiyamu.Pamodzi ndi zitsulo zovuta ku makina, kuphatikizapo zinthu zowonongeka kwambiri monga titaniyamu ndi ma alloys ake.
Standard Etch Tolerances: Kulekerera ndizofunikira kwambiri pamapangidwe aliwonse, ndipo kulekerera kwa PCE kumatha kusiyanasiyana kutengera makulidwe azinthu, zakuthupi, komanso luso la wopereka PCE ndi luso lake.
Njira ya Micrometal Etching Group imatha kupanga magawo ovuta okhala ndi zololera zotsika ngati ± 7 ma microns, kutengera zakuthupi ndi makulidwe ake, omwe ndi apadera pakati pa njira zonse zopangira zitsulo. woonda (2-8 micron) photoresist layers, zomwe zimathandiza kulondola kwambiri panthawi ya etching.Imathandiza Etching Group kuti ikwaniritse kukula kwazing'ono kwambiri za ma micron 25, ma apertures osachepera 80 peresenti ya makulidwe a zinthu, ndi kulolerana kobwerezabwereza kwa ma micron amodzi.
Monga kalozera, gulu la micrometal's Etching Group limatha kupanga zitsulo zosapanga dzimbiri, faifi tambala ndi aloyi zamkuwa mpaka ma microns 400 mu makulidwe okhala ndi mawonekedwe otsika mpaka 80% a makulidwe azinthu, ndi kulolerana kwa ± 10% ya makulidwe.Chitsulo chosapanga dzimbiri, faifi tambala ndi mkuwa. ndi zipangizo zina monga malata, aluminiyamu, siliva, golidi, molybdenum ndi titaniyamu thicker kuposa 400 microns akhoza mbali kukula kwake otsika 120% ya makulidwe zinthu ndi kulolerana ± 10% makulidwe.
PCE yachikhalidwe imagwiritsa ntchito kukana kwakanema kowuma kowuma, komwe kumasokoneza kulondola kwa gawo lomaliza komanso kulolerana komwe kulipo, ndipo kumatha kukwaniritsa kukula kwa ma microns a 100 ndi kabowo kakang'ono ka 100 mpaka 200 peresenti ya makulidwe azinthu.
Nthawi zina, njira zopangira zitsulo zachikhalidwe zimatha kupirira zolimba, koma pali malire.Mwachitsanzo, kudula kwa laser kungakhale kolondola mpaka 5% ya makulidwe achitsulo, koma kukula kwake kochepa kumangokhala 0.2 mm.PCE kumatha kukwaniritsa muyezo wocheperako. Kukula kwa mawonekedwe a 0.1mm ndi mipata yaying'ono kuposa 0.050mm ndizotheka.
Komanso, tiyenera kuzindikira kuti laser kudula ndi "mfundo imodzi" zitsulo njira, kutanthauza kuti zambiri zodula kwa mbali zovuta monga maukonde, ndipo sangathe kukwaniritsa kuya / chosema mbali zofunika zipangizo madzimadzi monga utsi pogwiritsa ntchito etching kwambiri. Mabatire ndi zosinthira kutentha zimapezeka mosavuta.
Pankhani yotha kutengera kulondola kolondola komanso kuthekera kocheperako ka PCE, kupondaponda kumatha kubwera pafupi kwambiri, koma kusinthanitsa ndiko kupsinjika komwe kumagwiritsidwa ntchito popanga zitsulo komanso mawonekedwe otsalira a burr. wa kupondaponda.
Zigawo zosindikizira zimafuna mtengo wamtengo wapatali pambuyo pokonza ndipo sizingatheke pakanthawi kochepa chifukwa chogwiritsa ntchito zida zachitsulo zamtengo wapatali zopangira zigawozo.Kuonjezera apo, kuvala kwa zida ndi vuto popanga zitsulo zolimba, zomwe nthawi zambiri zimafuna kukonzanso zodula komanso zowononga nthawi.PCE. amatchulidwa ndi ambiri opanga ma akasupe opindika ndi opanga zida zovuta zachitsulo chifukwa cha zinthu zake zopanda kupsinjika komanso zopanda nkhawa, kuvala zida za ziro, komanso kuthamanga kwamagetsi.
Zapadera popanda mtengo wowonjezera: Zapadera zimatha kupangidwa kukhala zinthu zopangidwa pogwiritsa ntchito lithography chifukwa cha "malangizo" am'mphepete mwa njirayo. Mwa kuwongolera nsonga yokhazikika, ma profayilo angapo amatha kuyambitsidwa, kulola kupanga nsonga zakuthwa, monga zogwiritsidwa ntchito ngati masamba azachipatala, kapena mipata yokhotakhota yolondolera kutuluka kwamadzi mu sefa.
Zida zotsika mtengo komanso kapangidwe kake: Kwa OEMs m'mafakitale onse omwe amayang'ana zida zazitsulo zolemera, zovuta komanso zenizeni, PCE tsopano ndiyo ukadaulo wosankha chifukwa sikuti imangogwira ntchito bwino ndi ma geometries ovuta, komanso imalola kusinthasintha kwa injiniya wa Design. sinthani mapangidwe asanafike popanga.
Chinthu chachikulu pakukwaniritsa izi ndikugwiritsa ntchito zida za digito kapena magalasi, zomwe zimakhala zotsika mtengo kupanga ndipo chifukwa chake zotsika mtengo m'malo ngakhale mphindi zisanayambe kupanga. zimalimbikitsa ukadaulo pomwe opanga amayang'ana kwambiri magwiridwe antchito m'malo mwa mtengo.
Ndi njira zachikhalidwe zopangira zitsulo, tinganene kuti kuwonjezeka kwa gawo la zovuta kumafanana ndi kuwonjezeka kwa mtengo, zomwe zambiri zimakhala zopangidwa ndi zida zamtengo wapatali komanso zovuta.Ndalama zimakweranso pamene matekinoloje achikhalidwe amayenera kuthana ndi zinthu zomwe sizili zoyenera, makulidwe ndi masukulu, onse omwe alibe mphamvu pamtengo wa PCE.
Popeza PCE sagwiritsa ntchito zida zolimba, kusinthika ndi kupsinjika maganizo kumachotsedwa.Kuonjezera apo, zigawo zomwe zimapangidwira zimakhala zowonongeka, zimakhala ndi malo oyera komanso opanda burrs, popeza chitsulo chimasungunuka mofanana mpaka geometry yofunidwa ikupezeka.
Kampani ya Micro Metals yapanga tebulo losavuta kugwiritsa ntchito kuti lithandizire mainjiniya opanga kuwunikiranso zosankha zomwe zilipo pazithunzi zapafupi, zomwe zitha kupezeka pano.
Economical prototyping: Ndi PCE, ogwiritsa ntchito amalipira pepala m'malo mwa gawo lililonse, zomwe zikutanthauza kuti zigawo zomwe zili ndi ma geometries osiyanasiyana zimatha kusinthidwa nthawi imodzi ndi chida chimodzi. ndalama zomwe zimachokera mu ndondomekoyi.
PCE ingagwiritsidwe ntchito pafupifupi mtundu uliwonse wachitsulo, kaya ndi wofewa, wolimba kapena wonyezimira.Aluminiyamu imadziwika kuti ndi yovuta kuwombera chifukwa cha kufewa kwake, ndipo imakhala yovuta kudula laser chifukwa cha zinthu zonyezimira.Momwemonso, kuuma kwa titaniyamu ndizovuta.Mwachitsanzo , Micrometal yapanga njira zogulitsira ndi etching chemistries ya zida ziwiri zapaderazi ndipo ndi imodzi mwamakampani ochepa padziko lonse lapansi omwe ali ndi zida za titaniyamu.
Phatikizani izi ndi mfundo yakuti PCE ndi yofulumira kwambiri, ndipo zifukwa zomwe zikukulirakulira kutengera luso lamakono m'zaka zaposachedwa zikuwonekeratu.
Akatswiri opanga mapulani akutembenukira ku PCE pomwe akukumana ndi kukakamizidwa kuti apange zing'onozing'ono, zovuta kwambiri zachitsulo.
Monga momwe zilili ndi njira iliyonse yosankha, okonza amafunikira kumvetsetsa zenizeni za teknoloji yosankhidwa yopangira poyang'ana mapangidwe ndi magawo.
