    K A B T R O N I C S S O L D E R I N G Soldering This manual can’t teach the art of soldering, but here are the basics. Remember, you need to make over 700 GOOD solder joints for each slice; each bad joint will be an adventure in troubleshooting.
  • Page 7 K A B T R O N I C S S O L D E R I N G A good solder joint will form a shiny curved surface bonding the lead and the pad on the PC board. If the lead wasn’t heated enough to melt the solder, the solder will wick in to the pad, but will not adhere to the lead.
