Soldering SMD by soldering iron
My method is used widely. I use a 25W iron with a 'standard' tip. Position the item to be soldered accurately, and 'tack' diagonally opposite pins, 1st one diagonal, then the other. Then starting from one end pin, run solder over ALL of the pins on one side. Apply de-solder braid in line with the pins and re-heat with the soldering iron, moving the braid away from the item. Repeat using fresh braid, until all excess solder removed. Pause briefly to let the item cool a little, then do other side(s). Buzz out adjacent connections to check for shorts.
Practise on some scrap/non-essential items before attempting soldering expensive ones!
