Njira yoyika nthunzi ya vacuum nthawi zambiri imaphatikizapo kuyeretsa pamwamba pa nthaka, kukonzekera musanayike, kuyiyika nthunzi, kukweza, kukonza pambuyo poyika, kuyesa, ndi zinthu zomalizidwa.
(1) Kuyeretsa pamwamba pa nthaka. Makoma a chipinda chotsukira mpweya, chimango cha pansi ndi mafuta ena a pamwamba, dzimbiri, zinthu zotsalira zotsukira mpweya zimakhala zosavuta kusungunuka mu vacuum, zomwe zimakhudza mwachindunji kuyera kwa filimuyo ndi mphamvu yolumikizira, ziyenera kutsukidwa musanatsuke.
(2) Kukonzekera musanaphike. Kupaka vacuum yopanda kanthu pamlingo woyenera wa vacuum, substrate ndi zinthu zophikira kuti zikonzedwe. Kutenthetsa substrate, cholinga chake ndikuchotsa chinyezi ndikuwonjezera mphamvu yolumikizira ya nembanemba. Kutenthetsa substrate pansi pa vacuum yayikulu kumatha kuchotsa mpweya wothira pamwamba pa substrate, kenako kutulutsa mpweya kuchokera mchipinda chopopera ndi pampu ya vacuum, zomwe zimathandiza kukonza digiri ya vacuum ya chipinda chopopera, kuyera kwa filimuyo ndi mphamvu yolumikizira ya maziko a filimuyo. Pambuyo pa digiri inayake ya vacuum, gwero loyamba la evaporation ndi mphamvu yochepa yamagetsi, filimuyo imatenthetsa kapena kusungunuka kale. Pofuna kupewa evaporation kupita ku substrate, phimbani gwero la evaporation ndi zinthu zoyambira ndi baffle, kenako lowetsani mphamvu yayikulu yamagetsi, zinthu zopopera zimatenthedwa mwachangu kutentha kwa evaporation, evaporation kenako kuchotsa baffle.
(3) Kutuluka kwa nthunzi. Kuwonjezera pa gawo la nthunzi kuti musankhe kutentha koyenera kwa substrate, kutentha kwa nthunzi ya zinthu zophikira kunja kwa mpweya ndi chinthu chofunikira kwambiri. Kutuluka kwa mpweya womwe ndi vacuum yophimba chipinda, kumatsimikiza kuchuluka kwa mamolekyulu a mpweya omwe akuyenda mumlengalenga ndi mtunda wina wa nthunzi pansi pa nthunzi ndi maatomu otsala a mpweya komanso kuchuluka kwa kugundana pakati pa maatomu a nthunzi.
(4) Kutsitsa. Mukamaliza kukhuthala kwa filimuyi kuti ikwaniritse zofunikira, phimbani gwero la evaporation ndi baffle ndikusiya kutentha, koma musawongolere mpweya nthawi yomweyo, ndikofunikira kupitiriza kuziziritsa pansi pa vacuum kwa nthawi yayitali kuti muziziritse, kupewa plating, zinthu zotsalira za plating ndi kukana, gwero la evaporation ndi zina zotero zomwe zasungunuka, kenako siyani kupompa, kenako tulutsani mpweya, tsegulani chipinda cha vacuum kuti muchotse substrate.
