Chifukwa choyamba:Tiyenera kuganizira ngati ndi vuto lakapangidwe kakasitomala.Ndikofunikira kuyang'ana ngati pali njira yolumikizirana pakati pa pedi ndi pepala lamkuwa, zomwe zingayambitse kutentha kosakwanira kwa pedi.
Chifukwa chachiwiri:Kaya ndi vuto la kasitomala.Ngati njira yowotcherera ndi yolakwika, idzakhudza mphamvu yotentha yosakwanira, kutentha ndi nthawi yolumikizana, zomwe zingapangitse kuti zikhale zovuta kuzimitsa.
Chifukwa chachitatu : kusungirako kosayenera.
① Munthawi yanthawi zonse, kupopera mbewu kwa malata kumakhala kodzaza ndi okosijeni kapena kufupikitsa mkati mwa sabata.
② Njira yamankhwala ya OSP imatha kusungidwa pafupifupi miyezi itatu.
③ Kusungidwa kwanthawi yayitali kwa mbale yagolide.
Chifukwa chachinayi: flux.
① Ntchitoyi sikokwanira kuchotsa kwathunthu ma oxidizingChithunzi cha PCBkapena SMD kuwotcherera malo.
② Kuchuluka kwa phala pa solder sikokwanira, ndipo kunyowetsa katundu wa flux mu solder phala sikwabwino.
③ Malata pamalumikizidwe ena a solder sakhala odzaza, ndipo mafuta otuluka ndi malata sangasakanizidwe mokwanira musanagwiritse ntchito.
Chifukwa chachisanu: pcb fakitale.
Pali zinthu zamafuta pa pad zomwe sizinachotsedwe, ndipo pad pamwamba pake sinatenthedwe ndi oxid musanachoke kufakitale.
Chifukwa chachisanu ndi chimodzi: reflow soldering.
Kuwotcha nthawi yayitali kwambiri kapena kutentha kwambiri kwa preheating kumabweretsa kulephera kwa ntchito ya flux.Kutentha kunali kochepa kwambiri, kapena liwiro linali lothamanga kwambiri, ndipo malata sanali kusungunuka.
Pali chifukwa chomwe solder pad ya bolodi yadera sivuta kuyika malata.Zikapezeka kuti sikophweka malata, m'pofunika kufufuza vuto mu nthawi.
PCBFuture yadzipereka kupereka makasitomala apamwamba kwambiriPCB ndi PCB msonkhano.Ngati mukuyang'ana wopanga msonkhano wa Turnkey PCB, chonde tumizani mafayilo anu a BOM ndi mafayilo a PCB kwa sales@pcbfuture.com.Mafayilo anu onse ndi achinsinsi kwambiri.Tikutumizirani mawu olondola okhala ndi nthawi yotsogolera mu maola 48.
