I need to be able to solder wires to the hidden pins of an smt ic. The ic is soldered directly to the pcb, and they are not visible. I need to access the PCM audio interface on a sim7500e, and the only way to do that would be for me to solder wires to the pcb, then resolder the sim7500e. Does anyone know how to do this? For reference, here is the prototyping module I am using.
Thank you for any help
