highest temperature chip can suffer

Other Parts Discussed in Thread: INA333, CC2540, CC2540T

Dear all,

Our team are going to encapsulate the PCB(with cc2540, tps62238,INA333) into  tpe or rubber. However this process requires the chip to bear high temperature(120 to 200) for some time.  

The question is :  Is there a temperature curve telling the relationship between temperature and longest time(before chip failure) under this temperature?

Or is there a chip failure temperature?

Thank you very much and hope you can give valuable information!

BR,

Bo

    Hello Bo,

    Will you be using the CC2540T, which is rated to a maximum 125C operating temperature? I don't have any data available beyond what is published in the data sheet for maximum operating conditions.

    Best wishes

    Hi Bo,

    If I understand your question correctly the device will only experience this high temperature during the rubber encapsulation process, right? As long as you are within the typical soldering reflow envelope, which I guess you will be, it should be fine.

    Cheers,
