Zingaphi iintlobo zebhodi yesekethe PCB inokohlulwa ngokwemathiriyeli?Zisetyenziswa phi?
Ukuhlelwa kwezinto eziphambili ze-PCB kubandakanya oku kulandelayo: i-bai isebenzisa i-FR-4 (isiseko selaphu lelaphu leglasi), i-CEM-1/3 (ifiber yeglasi kunye ne-substrate edibeneyo yephepha), i-FR-1 (i-laminate ye-copper esekelwe ephepheni), isiseko sesinyithi I-laminates ezifakwe kwi-Copper (ikakhulukazi i-aluminium-based, ezimbalwa zisekelwe kwintsimbi) ziyi-mo ...Funda ngokugqithisileyo -
Igridi yobhedu okanye ubhedu oluqinileyo?Le yingxaki yePCB ekufuneka uyicinge!
Yintoni ubhedu?Okubizwa ngokuba kuthululwe ubhedu kukusebenzisa indawo engasetyenziswanga kwibhodi yesiphaluka njengendawo yokubhekisela kwaye emva koko uyigcwalise ngobhedu oluqinileyo.Ezi ndawo zobhedu zikwabizwa ngokuba kukuzaliswa kobhedu.Ukubaluleka kokugquma ubhedu kukunciphisa i-impedance yocingo lomhlaba kunye ne-impro...Funda ngokugqithisileyo -
Ngamanye amaxesha kukho iinzuzo ezininzi kwi-PCB yobhedu yokubeka ezantsi
Kwinkqubo yoyilo lwePCB, ezinye iinjineli azifuni ukubeka ubhedu kuwo wonke umphezulu womaleko ongezantsi ukuze wonge ixesha.Ngaba oku kuchanekile?Ngaba iPCB kufuneka ifakwe ubhedu?Okokuqala, kufuneka sicace: i-plating yobhedu esezantsi iluncedo kwaye iyimfuneko kwi-PCB, kodwa ...Funda ngokugqithisileyo -
Iimpawu ezine ezisisiseko zesekethe ye-PCB RF
Apha, iimpawu ezine ezisisiseko zeesekethe zikanomathotholo ziya kutolikwa kwimiba emine: ujongano lwamaza kanomathotholo, umqondiso omncinci ofunekayo, umqondiso omkhulu wokuphazamiseka, kunye nokuphazamiseka kwesiteshi esikufutshane, kunye nezinto ezibalulekileyo ezifuna ingqalelo ekhethekileyo kwinkqubo yoyilo lwePCB. .Funda ngokugqithisileyo -
Ibhodi yephaneli yokulawula
Ibhodi yokulawula nayo luhlobo lwebhodi yesekethe.Nangona uluhlu lwesicelo lwayo alubanzi njengolo lweebhodi zeesekethe, luhlakaniphile kwaye luzenzekelayo kuneebhodi zesekethe eziqhelekileyo.Ukubeka nje, ibhodi yesiphaluka enokuthi idlale indima yokulawula ingabizwa ngokuba yibhodi yokulawula.Iphaneli yolawulo i...Funda ngokugqithisileyo -
