Iphakheji ye-vacuum ye-PCBukubeka ibhodi lesifunda eliphrintiwe (PCB) esikhwameni sokupakisha se-vacuum, sebenzisa ipompo ye-vacuum ukukhipha umoya esikhwameni, ukunciphisa ingcindezi esikhwameni ibe ngaphansi komfutho womoya, bese uvala isikhwama sokupakisha ukuqinisekisa ukuthi i-PCB alilimazi ngesikhathi sokupakishwa.Ukungcola okuvela endaweni engaphandle efana nomoya-mpilo, umswakama nothuli.Ukupakishwa kwevacuum kubaluleke kakhulu ekuvikelweni kwe-PCB, ikakhulukazi kwezinye izingxenye ezizwelayo namasekhethi anembe kakhulu.Ingavimbela ngempumelelo izinkinga ezifana ne-oxidation, ukugqwala kanye nogesi omile, futhi ithuthukise ikhwalithi nokuthembeka kwe-PCB.
Ngaphezu kwalokho, ukupakishwa kwe-vacuum kunganweba impilo ye-PCB futhi kwandise ukuphepha kwayo ngesikhathi sokuthutha nokugcinwa.Uma wenzaIphakheji ye-vacuum ye-PCB, kunezinto okumele uzinake.Okokuqala, kufanele uqinisekise ukuthi isikhwama sokupakisha sisezingeni eliphezulu futhi singagcina kahle isimo se-vacuum.
Okwesibili, i-desiccant idinga ukungezwa esikhwameni sokupakisha ukuze ibambe umswakama osele futhi igweme ukulimala ku-PCB.Okokugcina, iphampu yevacuum idinga ukusebenza ngokucophelela ukuze kuqinisekiswe ukukhishwa kahle komoya kanye nokuvala isikhwama.Ngamafuphi, ukupakishwa kwe-PCB vacuum kuyindlela ebalulekile yokuvikela neyokulondoloza ukuze kuqinisekiswe ukuthi i-PCB isesimweni esihle kakhulu ngesikhathi sokukhiqiza, ukuthuthwa nokugcinwa.
