- Notes on soldering
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
Put the board on a block-shaped table.
Put the paper between the board and the base, and outlines
these parts on it.
Set the replacing parts to fit this line.
Adjust the height of the replaced parts to match the board
and fix it with solder.
Apply silicon grease (GEM1057) to the backside of it.
