Lapho ibhodi le-PCB lifakwe i-vacuum lipakishwe futhi lithunyelwa ngemva kokuhlolwa komkhiqizo wokugcina, amabhodi e-batch oda, abakhiqizi bebhodi lesifunda jikelele bazokwenza i-inventory eyengeziwe noma balungiselele izingxenye eziyisipele zamakhasimende, bese bevala ukupakisha nokugcina ngemva kweqoqo ngalinye lama-oda. kuqediwe.Ilinde ukuthunyelwa.Ngakho kungani amabhodi e-PCB edinga ukupakishwa kwe-vacuum?Ungagcina kanjani ngemuva kokupakisha i-vacuum?Ingakanani impilo yeshalofu layo?I-Xiaobian elandelayo yabakhiqizi bebhodi lesekethe le-Xintonglian bazokunikeza isingeniso esifushane.
Indlela yokugcina yebhodi le-PCB nempilo yayo yeshalofu:
Kungani amabhodi e-PCB edinga ukupakishwa kwe-vacuum?Abakhiqizi bebhodi le-PCB banamathisela ukubaluleka okukhulu kule nkinga.Ngoba uma ibhodi le-PCB lingavalwanga kahle, igolide lokucwiliswa phezulu, i-tin spray kanye nezingxenye ze-pad zizokhipha i-oxidize futhi zithinte ukushisela, okungahambisani nokukhiqizwa.
Ngakho, kanjani ukugcina ibhodi PCB?Ibhodi lesifunda alihlukile kuneminye imikhiqizo, alikwazi ukuxhumana nomoya namanzi.Okokuqala, i-vacuum yebhodi le-PCB ayinakonakala.Lapho upakisha, ungqimba lwefilimu ye-bubble ludinga ukuzungezwa eceleni kwebhokisi.Ukumuncwa kwamanzi kwefilimu ye-bubble kungcono, okudlala indima enhle ebufakazini bomswakama.Yiqiniso, ubuhlalu obuvikela umswakama nakho buyabalulekile.Bese uwahlunga bese uwalebula.Ngemuva kokuvalwa, ibhokisi kufanele lihlukaniswe odongeni futhi ligcinwe endaweni eyomile nengenawo umoya kude nomhlabathi, futhi kufanele futhi livikelwe ekukhanyeni kwelanga.Izinga lokushisa le-warehouse lilawulwa kangcono ku-23±3℃, 55±10%RH.Ngaphansi kwezimo ezinjalo, amabhodi e-PCB anokwelashwa okungaphezulu okufana negolide lokucwiliswa, i-electro-gold, i-spray tin, ne-silver plating ngokuvamile angagcinwa izinyanga ezingu-6.Amabhodi e-PCB anokwelashwa okungaphezulu njengethayela lokucwiliswa kanye ne-OSP ngokuvamile angagcinwa izinyanga ezi-3.
Kumabhodi e-PCB angakaze asetshenziswe isikhathi eside, kungcono kakhulu kubakhiqizi bebhodi lesifunda ukudweba ungqimba lwepende elinobufakazi obuthathu kubo.Imisebenzi yepende enobufakazi obuthathu ingavimbela umswakama, uthuli kanye ne-oxidation.Ngale ndlela, impilo yokugcina yebhodi le-PCB izonyuswa ibe yizinyanga eziyisi-9.
