I have successfully implemented using the BQ51003 chip on a protoboard using a 10 mm diameter RX coil with a 20 mm diameter TX coil. However, now that I have had the PCB manufactured, power transfer is no longer happening. I have ruled out any manufacturing defects with the PCB and the schematic and passive values of the PCB are identical to the proto-board. Is there any known issues with this? My only possible thought is that the parasitic capacitances are sufficiently different between the proto-board and PCB so as to create an issue. Any recommendations into resolving this would be appreciated.
