CC2530: question about exposing soldered & programmed device to 150 celsius degrees

Part Number: CC2530
Other Parts Discussed in Thread: CC2592,

Hi everybody ,

I have a card  were I use 

  • CC2530F256RHAR 
  • CC2592RGVR

On production line we want to implement the following process:

  1. we soldered the 2 devices on the card 
  2. Programing  & test this card ( including the 2 devices ) 
  3. Soldering   this prebuilt  card ( with the 2 devices )  on another card  
  4. final test 

On the second soldering process (Soldering the  card on another PCB) the above components will expose to 150˚C for 2 minutes.

Does the second soldering process may affect the IC that have been programmed well already?

any other timing /temperature  I should consider ?  any other suggestion ?

thank you 

best regards

Carlo

    Colombo,

    The CC2592 and CC2530's peak solder temperature are both 260C, so 150C will not damage the device. However, I am not certain how this may possibly affect the programmed SW. Is this something you can try testing on your end?

    I would ensure that the device is never on outside of the operating temperature range, -40C~125C. 

    BR,

    Seong

    Hi Seong , 

    it will be for a limited time ( just soldering ) , but yes the device is programmed and I need a confirmation if this can be an issue or not : could you kindly help me with some tech experts ?   

    thank you 

    best regards
