      there is a very simple way of soldering down SMD components without
      being an octopus.

      Apply rework flux to the pads, (rework flux pen ), be generous
      Clean your soldering iron bit. Ideally close to a 1mm tip.
      put a wee blob of solder on the tip of the iron.
      Pick up the SMB component with SHORT , preferably with
      flat tips and
      HOLD the component on the pads.
      Touch the junction of the component and the pad so heat is applied to
      each.
      Watch as the solder flows underneath the component, remove the iron
      from the joint and let go of the component with the tweezers.
      Now just solder normally the other pad /legs.

        Richard,

         

        I wouldn't poohoo you for that as that was the exact way I was doing it before I got into hot air guns. Although I did it slightly different and presoldered one of the pads then held the part to the pad and applied heat. Same thing different location.

          Hi Tim , thanks
          It has the advantage over pre-soldering that the layer of solder is a
          bit thinner and avoids tombstoning, if hot air or IR reflow is used
          afterwards.
