Soldering Tool Head
As a compliment to the Pick and Place Tool, this tool would automatically solder components into place. This is one of the trickiest parts of the process for novices. It would be wonderful if it could be experienced from your chair, looking into the viewing window of your build area.
To test: to see if solder paste can be melted with a heat gun, then it will work to solder a component to the board. Also, the components must all survive the heatgun heat with no damage to the components. That may prove to be challenge, but if all goes well, the components will be soldered and functional.
If that fails, attempts could be made at a solder iron tipped print head, but it might get tricky with component leads and other complications.
