If you already saw the soldering video, here two photos of the result.
To get this result, I was inspired by the way Saar from Boldport was soldering his own projects, I adapted his technique.
- After initial soldering, I flush cut carefully the wire as close as possible to the board. Cutting off any solder with the wire to make it flat.
- Next I add more solder to the point until it forms a small round dome.
- On the component side I add solder if necessary to fill the hole and make a smooth transition from the hole to the wire.
For this photos I use solder with lead – this is a huge exception. It is the only way to get this shiny domes. Normally I work with lead free components and solder according to ROHS.
