    A component I am working with contains a PCB that has resistive material printed directly onto the PCB. This is the first time I've seen this. I've done much Google searching, but I can't seem to determine what exactly this technology is called. Perhaps someone knows what I am talking about and can direct me to some literature?

    The reason I am interested in this is because I believe one or more of these resistors to be the point(s) of failure. Having a mechanical background (as well as electrical) I'm inclined to believe thermal cycling has cracked the resistive material and increased the resistance. Is this a typical failure mode of this technology? Are there any others?

    Thanks for the info. I will read up on that. Any thoughts on common failure modes?
