Zogulitsa
Monga ogulitsa maukadaulo osiyanasiyana a PCB, ma voliyumu, zosankha zanthawi yotsogolera, tili ndi zida zosankhidwa bwino zomwe bandwidth yayikulu yamitundu yosiyanasiyana ya PCB imatha kuphimbidwa ndipo imapezeka nthawi zonse mnyumba.
Zofunikira pazazinthu zina kapena zapadera zimathanso kukwaniritsidwa nthawi zambiri, koma, kutengera zofunikira, mpaka masiku 10 ogwira ntchito angafunike kuti agule zinthuzo.
Lumikizanani nafe ndikukambirana zosowa zanu ndi imodzi mwazogulitsa zathu kapena gulu la CAM.

Q&A Momwe Mungayesere Kukhazikika Kwa Khoma Lamabowo Ndi Zofananira Zofananira
Momwe mungayesere kulimba kwa khoma ndi zofananira nazo?Khoma la dzenje limachotsa zomwe zimayambitsa ndi zothetsera?
Mayeso a Hole wall kukoka adagwiritsidwa ntchito m'mbuyomu kuti magawo obowo akwaniritse zofunikira pakusonkhanitsa.General mayeso ndi solder waya pa bolodi pcb kudzera mabowo ndiyeno kuyeza kukoka kunja mtengo ndi mavuto mita.Malinga ndi zomwe zachitika, zikhulupiriro zake ndizokwera kwambiri, zomwe zimapangitsa kuti pasakhale zovuta zilizonse pakugwiritsa ntchito.Zogulitsa zimasiyanasiyana malinga ndi zomwe zili
pazifukwa zosiyanasiyana, tikulimbikitsidwa kutchulanso za IPC zokhudzana.
Dzenje khoma kulekana vuto ndi nkhani osauka adhesion, amene nthawi zambiri chifukwa cha zifukwa ziwiri wamba, choyamba ndi nkhwawa osauka desmear (Desmear) kumapangitsa kukangana sikokwanira.Zina ndi njira zopangira mkuwa zopanda ma electroless kapena zokutidwa mwachindunji ndi golidi, Mwachitsanzo: kukula kwa zipilala zazikuluzikulu kumabweretsa kusamata bwino.Zachidziwikire kuti pali zinthu zina zomwe zingayambitse vutoli, komabe zinthu ziwirizi ndizovuta kwambiri.
Pali zoipa ziwiri za dzenje khoma kulekana, woyamba kumene ndi mayeso ntchito chilengedwe ankhanza kapena okhwima, zidzachititsa pcb bolodi sangathe kupirira kupsinjika thupi kotero kuti anapatukana.Ngati vutoli ndi lovuta kuthetsa, mwinamwake muyenera kusintha zinthu za laminate kuti mukwaniritse kusintha.
Ngati silovuto lomwe lili pamwambapa, makamaka chifukwa cha kusakanizika kosauka pakati pa dzenje lamkuwa ndi khoma la dzenje.Zifukwa zomwe zingayambitse gawoli ndi monga kusakwanira kwa khoma la dzenje, makulidwe a mankhwala amkuwa, ndi kuwonongeka kwa mawonekedwe komwe kumachitika chifukwa cha kusapanga bwino kwa mankhwala amkuwa.Izi zonse ndi chifukwa chotheka.Zachidziwikire, ngati kubowola kwabwino kuli koyipa, kusiyanasiyana kwa khoma la dzenje kungayambitsenso zovuta zotere.Ponena za ntchito yofunika kwambiri yothetsera mavutowa, iyenera kukhala yoyamba kutsimikizira gwero lake ndiyeno kuthana ndi gwero lachoyambitsacho chisanatheretu.
