How to get the data from the internal memory card?

A few weeks ago, my Mobile was broken. Now I just want to save the data from the internal memory card. I already removed the motherboard but the memory card is soldered. So I guess the only way is to get an adapter from the motherboard to USB 2.0/3.0. Do you agree or do you have any better ideas?

Can you recommend any adapter?

Thank you all for your help!
