In regards to ESD Safe Tools (Tweezers, Vacuum Pick-Up Tools, etc.) what level of documentation / certification do we need to maintain for ESD compliance? Is it necessary to obtain certification to ESD specs from the tool manufacturer to document compliance to ESD standards or can we test and/or audit internally?
Hello and welcome to the forum.
There are two responses for this question. First answer is easy. For product qualification of ESD control items there are three ways they can be qualified. They are:
Product specification from manufacturer
Independent laboratory evaluation (third party)
Internal laboratory evaluation
All these items require testing to table 2, 3, or 4 in ANSI/ESD S20.20 - 2021 which call out specific standards.
Second answer is more specific to your question. Items that you have listed tweezers, vacuum pick-ups and other item, are not listed in the table. In this case, qualification is up to the user to determine. For something like tweezers, there may be a requirement for the tweezer itself but it is used with a person, so a quick resistance to ground check while holding the tweezer may be enough.
If you have any further questions, please feel free to post.
