Hello everyone!
I'm designing a flexible PCB and I'm a bit confused with the stack up. I've seen that the nRF52840 development board has an NFC antenna with the following stack up:
The thing is that I wanted to use this stack up as a model, and what I'm most interested in is knowing how the "most rigid" part of the antenna was made, that is, the part that connects to the NFC connector on the development board.
My question is: How is that rigid area of the NFC antenna made?
I am referring to this area:
Although my design uses a 34-pin FPC connector, could I use this stack up or would I have to make many more modifications?
I'm a bit lost with flexible boards, any help is appreciated
Thank you very much in advance
