Golder Finger PCBA Printed Circuit Board Assembly
Photoplate: Kugwiritsa ntchito ukadaulo wa photoplate kusamutsa madongosolo ozungulira pagawo.Zinthu zamkuwa zochulukira zimachotsedwa ndi photomask ndi etching yamankhwala kuti apange mawonekedwe ofunikira.Chithandizo chopangidwa ndi golide: Kuchiza kwa golide kumachitidwa pa chala cha golide kuti apititse patsogolo kayendedwe ka magetsi ndi kukana dzimbiri.Nthawi zambiri, njira ya electroplating imagwiritsidwa ntchito poyika zitsulo zachitsulo pamwamba pa chala chagolide.Kuwotcherera ndi msonkhano: Weld ndi kusonkhanitsa zigawo zikuluzikulu ndi PCB bolodi kuonetsetsa kuti olowa solder ndi olimba ndi odalirika.Gwiritsani ntchito ukadaulo wapamtunda (SMT) kapena ukadaulo wa plug-in soldering, sankhani malinga ndi zofunikira.Kuyang'anira ndi kuyezetsa kwaubwino: Kuyang'anira ndi kuyezetsa kokhazikika kumachitika panthawi yopanga kuti zitsimikizire kuti bolodi la PCB chala chagolide likukwaniritsa zofunikira komanso zofunikira.
Kuphatikizira kuyang'ana kowonekera, kuyesa kwa mawonekedwe amagetsi, kuyesa kwa impedance, etc.Anti- dzimbiri ❖ kuyanika mankhwala ikuchitika monga pakufunika kusintha dzimbiri kukana kwa gulu PCB.Kupaka ndi kubweretsa: Sungani bwino PCB ya Golden Finger yomalizidwa kuti mupewe kuwonongeka kapena kuipitsidwa.Mukamaliza kuyendera komaliza, perekani kwa kasitomala pa nthawi yake.Goldfinger PCB gulu kupanga ndondomeko amafuna mwatsatanetsatane mkulu ndi kulamulira okhwima kuonetsetsa mankhwala khalidwe ndi bata.Tidzagwira ntchito motsatira ndondomeko yomwe ili pamwambayi kuti tikupatseni mankhwala apamwamba a golide a PCB.
