PCB vacuum ukupakishwakukubeka ibhodi yesekethe eprintiweyo (PCB) kwingxowa yokupakisha, sebenzisa impompo yokucoca ukukhupha umoya engxoweni, ukunciphisa uxinzelelo engxoweni ukuya ngaphantsi koxinzelelo lomoya, kwaye emva koko utywine ingxowa yokupakisha ukuqinisekisa ukuba iPCB. ayonakaliswa ngexesha lenkqubo yokupakisha.Ungcoliseko oluvela kwindawo yangaphandle efana neoksijini, ukufuma nothuli.Ukupakishwa kweVacuum kubaluleke kakhulu kukhuseleko lwePCB, ngakumbi kumacandelo athile abuthathaka kunye neesekethe ezichanekileyo.Inokuthintela ngempumelelo iingxaki ezifana ne-oxidation, i-corrosion kunye nombane ongatshintshiyo, kunye nokuphucula umgangatho kunye nokuthembeka kwe-PCB.
Ukongeza, ukupakishwa kwe-vacuum kunokwandisa ubomi bePCB kwaye kwandise ukhuseleko lwayo ngexesha lokuthutha kunye nokugcinwa.Xa usenzaPCB vacuum ukupakishwa, kukho izinto ezithile omele unikele ingqalelo kuzo.Okokuqala, kufuneka uqinisekise ukuba ingxowa yokupakisha ikumgangatho ophezulu kwaye inokugcina ngokufanelekileyo i-vacuum state.
Okwesibini, i-desiccant kufuneka yongezwe kwingxowa yokupakisha ukuze ithathe umswakama oseleyo kwaye igweme umonakalo kwi-PCB.Ekugqibeleni, impompo yokucoca kufuneka iqhutywe ngononophelo ukuqinisekisa ukutsalwa okufanelekileyo komoya kunye nokutywinwa kwesikhwama.Ngamafutshane, ukupakishwa kwe-vacuum ye-PCB lukhuselo olubalulekileyo kunye nomlinganiselo wokugcinwa kokuqinisekisa ukuba i-PCB ikwimeko engcono ngexesha lemveliso, ukuthutha kunye nokugcinwa.
