Look at Kemet, one of the biggest manufacturer of tantalum capacitors. They ensure that all of their tantalum is conflict-free. Is Kemet a Fairphone provider? As a hardware engineer, I’m interested in confirm this point.
The “100% conflict-free tantalum” logo goes to kemet.com/conflictfree.
I’m looking forward your response!
It’s not listed as a supplier, see this page for tons of info: Mapping the journey of your phone
