Habka dhigista uumiga faakuumka guud ahaan waxaa ka mid ah nadiifinta dusha sare ee substrate, diyaarinta ka hor daaha, dhigista uumiga, rarista, daaweynta dahaarka ka dib, tijaabinta, iyo alaabta dhammaatay.
(1) Nadiifinta dusha sare ee substrate. Darbiyada qolka Vacuum, jir substrate iyo saliid kale oo dusha sare ah, miridhku, alaabta dahaadhay hadhaaga ah waa ay fududahay in la uumi in vacuum ah, si toos ah u saameeya daahirsanaanta lakabka filimka iyo xoogga isku xidhka, waa in la nadiifiyaa ka hor dahaadhay.
(2) Diyaarinta ka hor daahan. Dahaarka faakuum madhan ilaa heerka faakuumka ku haboon, substrate-ka iyo alaabta daahan ee pretreatment. Kuleylinta substrate-ka, ujeeddadu waa in meesha laga saaro qoyaanka oo kor loogu qaado xoogga isku xidhka xuubka. Kuleylinta substrate-ka hoostiisa vacuum sare waxay qurxin kartaa gaaska adsorbed ee dusha sare ee substrate-ka, ka dibna ku daalin gaaska ka soo baxa qolka faakuumka bamka faakuumka, kaas oo ku habboon hagaajinta heerka vacuum ee qolka daahan, nadiifnimada lakabka filimka iyo xoogga isku xirka ee saldhigga filimka. Ka dib marka la gaaro shahaado faakuum gaar ah, isha ugu horeysa ee uumiga leh oo leh awood hoose oo koronto ah, kulaylka filimka ama ka hor dhalaalay. Si looga hortago uumi-baxa substrate-ka, ku dabool isha uumiga iyo walxaha isha leh baffle, ka dibna geli awood sare oo koronto ah, walxaha dahaarka ayaa si degdeg ah loo kululeeyaa heerkulka uumiga, uumiga ka dibna ka saar baffle.
(3) Uumi-baxa. Marka lagu daro heerka uumi-baxa si loo doorto heerkulka substrate-ka ku habboon, ku dhejinta heerkulka uumiga walxaha ka baxsan kaydinta cadaadiska hawada ayaa sidoo kale ah cabbir aad u muhiim ah. Dhigista cadaadiska gaaska oo ah vacuum qolka dahaarka, ayaa go'aamisa celceliska kala duwanaanta bilaashka ah ee molecules gaaska ku socda booska uumiga iyo fogaanta uumiga hoostiisa ee uumiga iyo haraaga gaaska iyo tirada isku dhaca u dhexeeya atamka uumiga.
(4) dejinta. Ka dib marka dhumucda lakabka filimka si ay u buuxiyaan shuruudaha, dabooli isha uumiga leh baffle iyo joojinta kuleylka, laakiin isla markiiba ha hagin hawada, baahida loo qabo in la sii wado qaboojinta hoos xaaladaha vacuum muddo wakhti ah si ay u qaboojiso, si looga hortago dahaadhay, haraaga dahaadhays wax iyo iska caabin, isha uumiga iyo wixii la mid ah oxidized, ka dibna joojiso bamgareynta, ka dibna barar, fur furka qolka subacuumka.
