SoSO said that not many people use heat transfer in the forum, so I will share a heat transfer board that I just finished last night.
Cause: I need to do an experiment of acceleration sensor for work. The fastest time for PCB manufacturer to make the board is 1 week (expedited). Usually it takes 1-2 weeks to delay the development cy...
