A soldering tip (no pun intended) that may help those who want to repair their PLM. I have not repaired a PLM, but this works on many other devices I have repaired over the years. Commercially manufactured boards typically use a higher temperature low lead or lead free solder. This makes is more difficult to desolder without a dedicated desoldering station. To desolder, as you heat the component, add a small amount of leaded/lower temperature solder. This solder will transfer the heat better to the board trace and then mix with the factory solder, making it much easier vacuum or wick away. This reduces the overall amount of heat applied to the board and can help avoid lifted traces.
