Pamene bolodi PCB ndi zingalowe mmatumba mmatumba ndi kutumizidwa pambuyo anayendera chomaliza mankhwala, kwa matabwa mu madongosolo mtanda, ambiri dera gulu opanga kupanga kufufuza zambiri kapena kukonzekera mbali yopuma kwa makasitomala, ndiyeno vakuyumu ma CD ndi kusunga pambuyo gulu lililonse malamulo. yatsirizidwa.Akuyembekezera kutumiza.Ndiye n'chifukwa chiyani matabwa PCB amafunikira vacuum ma CD?Momwe mungasungire pambuyo pakulongedza vacuum?Kodi shelufu yake imakhala yayitali bwanji?Otsatira a Xiaobian opanga ma board a Xintonglian akupatseni chidziwitso chachidule.
Njira yosungira ya bolodi la PCB ndi moyo wake wa alumali:
Chifukwa chiyani ma board a PCB amafunikira ma vacuum ma CD?Opanga PCB board amaphatikiza kufunikira kwakukulu ku vutoli.Chifukwa gulu la PCB likapanda kusindikizidwa bwino, golide womiza padziko lapansi, utsi wa malata ndi zigawo za pad zidzasokoneza ndi kukhudza kuwotcherera, zomwe sizingathandize kupanga.
Kotero, momwe mungasungire bolodi la PCB?Bolodi lozungulira silosiyana ndi zinthu zina, silingagwirizane ndi mpweya ndi madzi.Choyamba, vacuum ya bolodi la PCB silingawonongeke.Mukanyamula, filimu ya buluu iyenera kuzunguliridwa pambali pa bokosilo.Mayamwidwe amadzi a filimu ya kuwira ndi bwino, yomwe imagwira ntchito yabwino pakutsimikizira chinyezi.Inde, mikanda yoteteza chinyezi ndiyofunikanso kwambiri.Kenako sinthani ndikulemba zilembo.Pambuyo kusindikiza, bokosilo liyenera kupatulidwa ndi khoma ndikusungidwa pamalo owuma ndi mpweya wabwino kutali ndi nthaka, komanso liyenera kutetezedwa ku kuwala kwa dzuwa.Kutentha kwa nyumba yosungiramo katundu kumayendetsedwa bwino pa 23 ± 3 ℃, 55 ± 10% RH.Pazifukwa zotere, matabwa a PCB okhala ndi mankhwala apamtunda monga kumizidwa golide, electro-golide, malata opopera, ndi plating siliva akhoza kusungidwa kwa miyezi 6.Ma board a PCB okhala ndi mankhwala apamwamba monga malata omiza ndi OSP amatha kusungidwa kwa miyezi itatu.
Kwa matabwa a PCB omwe sanagwiritsidwepo ntchito kwa nthawi yaitali, ndi bwino kuti opanga mabwalo ozungulira azijambula utoto waumboni zitatu pa iwo.Ntchito za utoto wotsimikizira katatu zimatha kuteteza chinyezi, fumbi ndi okosijeni.Mwanjira imeneyi, moyo wosungira wa bolodi la PCB udzakulitsidwa mpaka miyezi 9.
