KIT
Necessary Batteries:
AA Batteries, 3 Pieces
(not included)
Troubleshoot soldering mistakes:
1. Preheat the solder area which
must be soldered AND the com-
ponent wire with the tip of the iron.
Do NOT overheat it!
2. Add some solder to the
soldering area and
component wre but NOT
TO MUCH!
3. Remove the solder and let
the hot liquid solder flow.
4. Take away the soldering iron
and DO NOT MOVE the
component or PCB!
5. Cut away the long component
wire just above the soldering spot.
The END RESULT is a nice and
shinny soldering spot which is
attached to the PCB copper and
component wire.
3.1 Soldering techniques:
Hold the iron like a pencil
Only add a little solder each time
Correct position for professional soldering
PERFECT SOLDERING
The soldering surface
looks nice and shinny
Not enough solder
Solder did not flow
Solder bridge
Two seperate solder spots are
connected to each other
Cold PCB
Solder is attached to
comonent wire but not to
the PCB copper
Only use leadfree ROSIN CORE solder!
Never use any liquid- or paste flux!
