Hi all ESD Expert,
I am wondering that is there anything should be noticed when using (Faraday cup + Coulomb meter) to measure static charge ?
- In order to measure static charge accurately, the capacitance of Faraday cup + Coulomb meter should be much lower than device under test(DUT), e.g., IC, right ?
- If it’s right, how can I guarantee DUT capacitance?
- Or I just no need to worry this issue, just measure it?
- Other thing - any document I can refer to?
Kindly advise, thank you.
