Now I would like to know how to get all the functionality of the RFID module, the Wi-Fi card on my PCB without soldering the Wi-Fi card or the RFID module on my PCB?
I reckon this is one of those cases where if you have to ask then the answer is "you can't"Designing PCBs for wireless devices is not trivial.
And trying to remove and re-use surface mount components would be madness.
the PCBs of our phones that have bluetooth, wifi, NFC and other comm modules are very compact
What do you advise me then?
What do you advise me then? to weld these modules over my PCB?
Most if not all of the components can be obtained without the pins or sockets soldered onto the board,
Here is about what I want to get in the end.
I'm not sure what you mean by that.If you mean that the OP should buy the basic surface-mount components and add them to a PCB that he has himself designed then my view if that he is unlikely to get a working solution with his present level of knowledge....R
