Hi dear brother&sisters; I m going mad for this option. I read all of the advices for this in forum but couldnt find a way (maybe i am stupid) Is anyone help me to expose copper on copper area? I want no solder mask on bottom side and give a heat to heatsink. Trying trying but could not find the way. Please help! Thanks

You only need to expose the copper where you want to solder something to it. If you want to use copper as a heatsink then you should probably design a footprint that includes a pad and thermal vias. See: [https://easyeda.com/forum/topic/How-to-avoid-DRC-errors-when-connecting-to-PCB-Footprints-a-k-a-PCB-Libs-90bf944fe3644b21a7d27a9e9d8df8d6](https://easyeda.com/forum/topic/How-to-avoid-DRC-errors-when-connecting-to-PCB-Footprints-a-k-a-PCB-Libs-90bf944fe3644b21a7d27a9e9d8df8d6)

The other thing you can do is to create an aperture in the solder mask layer: [https://oshwlab.com/andyfierman/how-to-make-an-aperture-in-the-solder-mask](https://oshwlab.com/andyfierman/how-to-make-an-aperture-in-the-solder-mask)
