Lokhu kwenza kube nokwenzeka ukulandelela ukushintshashintsha kokusebenza kwefilimu emuva kumapharamitha emishini kanye nezinguquko zenqubo.
Ngemikhiqizo enezincazelo eziningi, imishini kufanele isekele izakhiwo zeresiphi ezihlanganisiwe. Imisebenzi evamile efana nokupompa, ukuhlanza i-plasma, ukufakwa kwengqimba yokunamathela, noma ukupholisa ingalungiswa njengamamojula enqubo angasetshenziswa kabusha, kuyilapho izingqimba zengqimba ezithile zomkhiqizo zihlala zilawulwa ngokwahlukile.
Uhlelo oluzenzakalelayo kufanele futhi luphathe izimo ezingavamile ngokwesendlalelo samanje. Umcimbi omfushane we-arc ngesikhathi sesendlalelo sensimbi esijiyile ungaphathwa ngokucindezelwa kwe-arc okuzenzakalelayo kanye nokufakwa okuqhubekayo. Umcimbi ofanayo ngesikhathi sesendlalelo se-optical esikalini se-nanometer ungadinga ukuthi uhlelo luyeke, lubuyisele, luphinde isendlalelo, noma luphawule ibhetshi ukuze lihlolwe.
Le ndlela yokuphatha izinto ezihlukile eqaphela ungqimba iwumehluko obalulekile phakathi kokuzenzakalela komshini okuyisisekelo kanye nokuzenzakalela kwenqubo yangempela.
Kusukela Ekuqineni Kwemishini Yomuntu Ngamunye Kuya Ekuqineni Kwe-Whole-Stack
Inhloso enkulu yokuxhumanisa imishini akukhona nje ukuqeda isinyathelo ngasinye senqubo ngokuzenzakalelayo. Ukuqinisekisa ukuthi isitaki esinezingqimba eziningi esibekiwe siphinda njalo ukusebenza okuklanyelwe.
Lokhu kudinga ukuhlanganiswa kuzo zonke izigaba ezine. Okokuqala ukuhlanganiswa kwehadiwe phakathi kwamaphampu e-vacuum, ama-valve, izinsiza zikagesi, izinhlelo zegesi, imithombo, ama-heater, izindlela zokunyakaza, ama-sensor, kanye nama-cooling circuits. Okwesibili ukuhlanganiswa kwenqubo phakathi kokuhlanza, ukwenza kusebenze, ukubeka, ukusabela, ukuguquka, kanye nokupholisa. Okwesithathu ukuhlanganiswa kwedatha phakathi kwezindlela zokupheka, amasignali ezinzwa, amarekhodi e-alamu, imiphumela ye-endpoint, kanye nokulinganiswa kwekhwalithi. Okwesine ukuhlanganiswa komjikelezo wokuphila, okuhlanganisa ukuguguleka okuqondiwe, ukulungiswa komthombo, ukuhlanzwa kwegumbi, ukulinganiswa kwenzwa, isimo sezinto ezisetshenziswayo, kanye nokubuyiselwa kwenqubo.
Njengoba izembozo ezisebenzayo ziba nzima kakhulu, ikhono lemishini lizohlolwa ngokwandayo ngekhono layo lokulawula inqwaba yefilimu ephelele kunomthombo owodwa wokufaka. Imibuzo ebalulekile ngeke isakwazi ukukhawulelwa ekutheni umshini ungabeka yini into ethile. Abakhiqizi kuzodingeka futhi babonise ukuthi imishini ingagcina ikhwalithi yesixhumi, ilawule ukucindezeleka okuqongelelekile, inciphise ukungcoliswa okuwelanayo, ibuyisele ukukhukhuleka komthombo, ikhiqize kabusha ukusebenza kwe-spectral noma kagesi, futhi ifinyelele ukuhambisana kwe-batch-to-batch.
Ngakho-ke ukufakwa kwefilimu esebenzayo enezingqimba eziningi kuyindlela yokusebenzisana ehlanganisiwe phakathi kokwakhiwa kwemishini kanye nobunjiniyela bezinqubo. Ukuzinza kwe-vacuum kunikeza isisekelo semvelo, umthombo kanye nokuxhumanisa amandla okunquma ukulethwa kwezinto, ukulawulwa kwegesi kulawula ukwakheka, ukunyakaza kwe-substrate kunquma ukufana kwendawo, ukulawulwa kokushisa kanye nokubandlulula kuthonya ukukhula kwefilimu, kanye nokuqapha kwangaphakathi kuxhuma umphumela wangempela wokumboza ne-stack yesendlalelo eklanyelwe.
Kuphela uma lezi zinhlelo ezincane zisebenza ngaphansi kwesu elihlanganisiwe lokulawula inqubo lapho izendlalelo eziningi ngazinye ziba uhlelo lwefilimu olusebenzayo oluzinzile, oluphindaphindwayo, nolukhiqizwa ngobuningi.
