Use of ESD clothing in an electronic manufacturing process
Use of ESD clothing in an electronic manufacturing process
(OP)
Hi.
I'm new in the electronic manufacturing process, and I want to know if the use of ESD clothing helps to reduce the damage to the components, or this could be redundant when all the production lines are properly grounded and the people uses Wrist and leg straps and they are verified every time they enter to the production area.
Regards

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

Grounding the human (through a safety resistor of course!) is fine, but it does next to nothing about the charge build-up on his/her clothing if that clothing is extremely insulating. And if the clothing is static filled, then it's almost certainly extremely insulating.
It's simpler to use smocks than to try to regulate the employees' clothing choices.

"...and the employee's clothing as the highly-charged other plate."
The employee, being made of reasonably conductive meat, can be kept discharged through ground straps, etc. A sweater made of synthetic fibers has to be addressed through slightly conductive smocks

So far as I could tell, the root cause was that the ESD coating normally applied to Tyvek disposable lab coats produced a lot of unsightly 'dandruff', which displeased our medical doctor type customers, so we were paying extra to buy labcoats without the ESD coating.
I recalled the inventory of special labcoats and ordered ordinary coated ones, and the ESD problem went away. ... or at least I didn't hear about it anymore.
