PRODUCTION TESTING RF

[lucaross]

Hi ,

We are using the BL652 module with your nRF52832 chipset in our important product.

In our product the wireless connection is fundamental and we would like to test the reliability of the Antenna after the welding process.

Can we suggest some instruments to test the module and what it is important to test?

Is nordic use some tools or instrument to verify the module ?

Do you have any direct contact ?

I hope that nordic can support us in this important fase.

Best regards ,

Hi,

 

See nAN34 under Application Notes and nWP028 under Whitepapers in our documentation library. These describe how to set up a production test using a nRF5x DK/Bluetooth DTM tester or a Litepoint IQxel, respectively.

By transmitting (and possibly receiving) a number of packets you are able to verify the functionality of the radio and antenna. A faulty solder joint in the RF path will reduce the received signal strength by a considerable margin, while a faulty solder joint on any 32MHz crystal pin or DEC capacitor will prevent communication from taking place. Other radio parameters are not affected by the assembly and otherwise are verified in Nordic production test line, and probably the production line of the module manufacturer.

Whatever else you might have hooked up to the nRF we do not have any other support for testing, this you will need to implement yourselves.

 

Best regards,

Andreas

Hi ,

thanks for the answer.
