hi fellas

i soldered one PSOC4-BLE chip on my PCB, and just one chip no other components

and i found that pin-12 ant was short-circuited to GND

i want to know if it's normal or my chip might damaged from inside


thanks all

I don't have access to the die pictures so I will give you an answer from years of experience in RF testing and design . RF pins are generally at gnd when tested with an ohm Meter.
