    Vibration & Electrical Probe Conductivity

    Thanks IRstuff, Well, I guess it's better be well-informed than making speculations. Thanks for your input on vibration (negligible) of probe pins. I'll do a few more check ups on this topic before calling it goodbye to vibration. Thanks for the replies, this is a good site. I've book marked...

    Vibration & Electrical Probe Conductivity

    I'm involved with Wafer Testing. We have many probers that are used for this purpose in large production scale. One of the effort for engineer like me is to increase the yield. So, I'm looking for opportunity in this area. We have many products that are being tested with more than 20,000 touch...

    Vibration & Electrical Probe Conductivity

    You mean the vibration isolation of the table can help in minimizing the vibration of the probe? What about electrical conductivity of the probe? How to model the vibration of the pin as a function of time? Is is similar to sine wave? Any study on this? Ideally no test signal should be...

    Vibration & Electrical Probe Conductivity

    Hello, Has there been any study on the vibration of probe pin (used in semiconductor wafer testing) and its effect to electrical conductivity (maybe the contact area change)? If there is significant impact of vibration on electrical conductivity, how should I model the system to find the...
