Original question:

CC2650MODA: Manufacturing wash process for CC2650MODA.

CC2650MODA: wash of the module after installation on a PCB

Part Number: CC2650MODA

I have found this thread with the same question I have, but I need more certainty with the answer. Is it okay to wash the CC2650MODA module once installed on a PCB? Could the washing create paths that potentially compromise RF performance? Do we have testimony of customers that successfully wash boards with CC2650MODA on it?

Thank you!

    Hi Lenio,

    Washing with distilled water followed by properly drying the board before use should not create unwanted paths or compromise RF performance.  Can you provide any further details on the standard of washing desired to be implemented?  I will loop in a Hardware representative who can further comment on the matter.

    Regards,
    Ryan

    According to the customer, the concern is that due to the small holes in the shield the process would just get the components wet, and not actually wash them. If the module is assembled with no-clean flux the water would just spread the residue around which causes issues.

    Is the flux used to assemble the module no-clean flux?

    Here are the details of the washing process:
