PCB vacuum phukusi

PCB vacuum phukusindikuyika bolodi losindikizidwa (PCB) mu thumba lakuyika vacuum, gwiritsani ntchito pampu ya vacuum kuti mutenge mpweya m'thumba, kuchepetsa kuthamanga kwa thumba kuti mukhale pansi pa mphamvu ya mlengalenga, ndikusindikiza thumba kuti mutsimikizire kuti PCB. sichiwonongeka panthawi yolongedza.Kuwonongeka kochokera ku chilengedwe chakunja monga mpweya, chinyezi ndi fumbi.Kuyika kwa vacuum ndikofunikira kwambiri pachitetezo cha PCB, makamaka pazinthu zina zodziwika bwino komanso mabwalo olondola kwambiri.Itha kuteteza bwino mavuto monga makutidwe ndi okosijeni, dzimbiri ndi magetsi osasunthika, ndikuwongolera mtundu ndi kudalirika kwa PCB.
Kuphatikiza apo, kuyika kwa vacuum kumatha kukulitsa moyo wa PCB ndikuwonjezera chitetezo chake panthawi yoyendetsa ndi kusungirako.PochitaPCB vacuum phukusi, pali zinthu zina zofunika kuziganizira.Choyamba, muyenera kuonetsetsa kuti chikwama choyikapo ndi chapamwamba kwambiri ndipo chikhoza kukhalabe ndi vacuum state.
Kachiwiri, desiccant iyenera kuwonjezeredwa m'thumba kuti mutenge chinyezi chotsalira ndikupewa kuwonongeka kwa PCB.Potsirizira pake, pampu ya vacuum iyenera kugwiritsidwa ntchito mosamala kuti zitsimikizire kutulutsa mpweya wabwino ndi kusindikiza thumba.Mwachidule, PCB vacuum ma CD ndi njira yofunika yotetezera ndi kusunga kuti PCB ikhale yabwino kwambiri panthawi yopanga, kuyendetsa ndi kusunga.
