Electronics Tips: Surface Mount Soldering by Hand

Tools of the trade.jpg
My tools for easy surface mount soldering:
  • Reading Glasses - Helps seeing the small components up close
  • Soldering Vise - Something steady to hold the board so you can use both hands with the small parts
  • Fine Silver Solder - Surface mount components don't need a lot of solder, a fine thread helps keep the volume of solder small
  • Good Tweezers - Placement of the components requires a small gripper
  • Liquid Rosin Flux - Sticky flux helps hold the component down while also helping the solder adhere to all soldering surfaces
  • Spaghetti Noodle - Dipped quickly in the flux it provides a accurate tool to apply a small amount of flux to the board where needed (its cheep and disposable).

My tips for easy surface mount soldering:
  • Use large Surface Mount Components if possible. Even the larger sizes are pretty small and this makes them easier to handle by hand tools.
  • Hold the board in the vise as flat as possible to minimize slipping due to slope.
  • Use the spaghetti to apply the flux to the board for each solder pad for each component. A little flux goes a long way. A little between the pads helps keep the part from moving around until you make the first solder.
  • The first solder of each component is most important as it will hold the part for all others, so take time and it get this first one right.
