1.Umklamo Wokwenziwa Kwe-PCBA Idizayini yokwenziwa kwe-PCBA ixazulula inkinga yokuhlangana, futhi inhloso ukuzuza indlela emfishane yenqubo, izinga lokuphasa eliphezulu kakhulu, kanye nezindleko zokukhiqiza eziphansi kakhulu.Okuqukethwe kokuklama kufaka phakathi: ...Funda kabanzi -
Idizayini yokwenziwa yesakhiwo se-PCB nezintambo
Mayelana nokuhlelwa kwe-PCB nenkinga yezintambo, namuhla ngeke sikhulume ngokuhlaziywa kobuqotho besignali (SI), ukuhlaziywa kokuhambisana kwe-electromagnetic (EMC), ukuhlaziywa kobuqotho bamandla (PI).Ngikhuluma nje ngohlaziyo lwe-manufacturability analysis (DFM), ukwakheka okungenangqondo kokwenziwa nakho kuzoholela...Funda kabanzi -
Ukucubungula kwe-SMT
Ukucubungula kwe-SMT kuwuchungechunge lobuchwepheshe benqubo yokucubungula ngesisekelo se-PCB.Inezinzuzo zokunemba okuphezulu nokushesha okusheshayo, ngakho-ke yamukelwe abakhiqizi abaningi be-elekthronikhi.Inqubo yokucubungula i-chip ye-SMT ikakhulukazi ihlanganisa isikrini sikasilika noma ukukhishwa kweglue, ukukhwezwa noma...Funda kabanzi -
Indlela yokwenza ibhodi le-PCB elihle?
Sonke siyazi ukuthi ukwenza ibhodi le-PCB wukuguqula uhlaka oluklanyelwe lube yibhodi le-PCB langempela.Sicela ungayithathi kancane le nqubo.Kunezinto eziningi ezingenzeka ngokomgomo kodwa okunzima ukuzifinyelela kuphrojekthi, noma ezinye zingafinyelela izinto abanye abantu abangakwazi ukuzifeza iMoo...Funda kabanzi -
Indlela yokuklama i-PCB crystal oscillator?
Sivame ukuqhathanisa i-crystal oscillator enhliziyweni yesifunda sedijithali, ngoba wonke umsebenzi wesifunda sedijithali awunakuhlukaniswa nesignali yewashi, futhi i-crystal oscillator ilawula ngokuqondile lonke uhlelo.Uma i-crystal oscillator ingasebenzi, lonke uhlelo luzokhubazeka...Funda kabanzi -
Ukuhlaziywa kwezinhlobo ezintathu ze-PCB stencil technology
Ngokwenqubo, i-pcb stencil ingahlukaniswa ngezigaba ezilandelayo: 1. I-stencil yokunamathisela ye-Solder: Njengoba igama liphakamisa, isetshenziselwa ukuxubha unamathisele we-solder.Baza izimbobo ocezwini lwensimbi oluhambisana namaphedi ebhodi le-pcb.Bese usebenzisa i-solder unama ukupheda ebhodini le-PCB ...Funda kabanzi -
