Removing solder mask for heat dissipation

yamamotomas_0-1643264327713.png

As U201 is a motor driver, I would like to remove solder mask at the chip bottom for better heat dissipation.

What is the best way to do it ?

Hi @yamamoto.mas 

I hope you are doing well!

You can try the following steps :

1. Switch layer to 30 bStop

2. Draw Rectangle on the 30bStop
