① Qwalasela umgangatho wePCB.Ukuba umgangatho awulungile, kuya kuchaphazela kakhulu iziphumo ze-soldering.Ke ngoko, ukukhethwa kwePCB phambi kokuba i-reflow soldering ibaluleke kakhulu.Ubuncinci umgangatho kufuneka ube mhle;
② Umphezulu we-welding layer awucocekanga.Ukuba ayihlambulukanga, i-welding iya kuba ingaphelelanga, i-welding ingawa, okanye i-welding inokungalingani, ngoko qiniseka ukuba umgca we-welding ucocekile phambi kokudibanisa;
③Ilungu okanye iphedi ayigqibekanga.Xa enye yazo ingagqibekanga, umsebenzi wokuphinda uhlaziywe awukwazi ukugqitywa.Ngokuba xa kuthe kwalahleka enye kuzo, akuyi kusebenza ukuwelda, okanye ukuwelda akuyi komelela;
④ Enye into ekufuneka uyiqaphele kukutyeba kwengubo.Ndiyakholelwa ukuba abachwephesha abanamava baya kuqonda ukuba xa ubukhulu bengubo bunganelanga, kuya kukhokelela kwi-welding engafanelekanga, eya kuchaphazela i-reflow soldering;
⑤ Kukho ukungcola kwi-welding.Lo ngumcimbi wezinto eziphathekayo, izinto ezingcolileyo.Ngokuqhelekileyo kwaziwa ukuba xa izinto zingcolile, i-welding iya kuphumelela okanye ibe buthathaka, kwaye kuya kuba lula ukuphuka kamva.
