Installation tips

Here are some tips I have for you when you are soldering your chip into the PM-41 (2).

  • Cut your wires to be as short and direct as possible.
  • Pin 2, and 6 can be tricky. Don’t push on the components with your soldering iron or they might get knocked off the board. You can use tweezers to carefully solder them back on one side at a time, the orientation doesn’t matter.
  • Make sure the wires you are soldering don’t come into contact with other components or legs of chips.
