Kana iyo PCB bhodhi iri vacuum yakarongedzwa uye kutumirwa mushure mekupedzisira chigadzirwa chekuongorora, kune mabhodhi mune batch mirairo, iyo general redunhu bhodhi vagadziri vanogadzira yakawanda hesera kana kugadzirira zvimwe zvakasara zvevatengi, uyezve vacuum kurongedza uye kuchengetedza mushure meimwe batch yemirairo. inopedzwa.Yakamirira kutumirwa.Saka nei mabhodhi ePCB achida vacuum packaging?Nzira yekuchengetedza sei mushure mekuvhara vacuum?Inguva yakareba sei pasherufu yayo?Iyo inotevera Xiaobian yeXintonglian wedunhu bhodhi vagadziri vanokupa iwe sumo pfupi.
Nzira yekuchengetedza yePCB board uye hupenyu hwayo hwesherufu:
Sei PCB mabhodhi achida vacuum packaging?PCB board vagadziri vanoisa kukosha kukuru kune dambudziko iri.Nekuti kana iyo PCB bhodhi isina kuvharwa zvakanaka, iyo yekunyudza yegoridhe yepasi, tin spray uye pad zvikamu zvinozoita oxidize uye kukanganisa welding, iyo isingaite kugadzirwa.
Saka, sei kuchengeta PCB bhodhi?Bhodhi redunhu harina kusiyana nezvimwe zvigadzirwa, hazvigone kusangana nemhepo nemvura.Chekutanga pane zvese, vacuum yePCB board haigone kukuvara.Paunenge uchirongedza, chidimbu chebubble film chinoda kutenderedzwa padivi pebhokisi.Kunyura kwemvura kwefirimu yebubble kuri nani, iyo inobata basa rakanaka mukunyoro-uchapupu.Ehe, mabhero anodzivirira hunyoro anodiwa zvakare.Wozvironga wozvinyora.Mushure mekuvhara, bhokisi rinofanira kuparadzaniswa kubva pamadziro uye kuchengetwa munzvimbo yakaoma uye inofefetera kure nepasi, uye inofanirawo kudzivirirwa kubva kuzuva.Tembiricha yeimba yekuchengetera inodzorwa zvakanyanya pa23±3℃, 55±10%RH.Mumamiriro ezvinhu akadai, mabhodhi ePCB ane marapirwo epamusoro senge goridhe rekunyudza, electro-goridhe, tin yekupfapfaidza, uye sirivheri plating anogona kuchengetwa kwemwedzi mitanhatu.PCB mabhodhi ane kurapwa pamusoro senge kunyudza tin uye OSP anogona kazhinji kuchengetwa kwemwedzi mitatu.
Pamapuranga ePCB asina kushandiswa kwenguva yakareba, zvakanakisisa kuti vagadziri vebhodhi redunhu vapendi pepa retatu-uchapupu pepende pavari.Mabasa epende matatu-uchapupu anogona kudzivirira hunyoro, guruva uye oxidation.Nenzira iyi, hupenyu hwekuchengetedza kwePCB board huchawedzerwa kusvika kumwedzi ye9.
