ESD Smock - Cover Their Hair

Does A Person Wear ESD Smock Need To Cover Their Hair In PCB Assembly Manufacturing Line?
Some Places Are Required To Fully Cover Their Hair, Some Places Not.

Hello and welcome to the forum.

There are no requirements on hair from an ESD point of view. There may be requirements from a contamination point of view.

Some of the reasons from an ESD perspective is the thought that hair is an insulator and could generate an electrostatic field. This may be the case but if the hair is kept 300 mm away or in the case of long hair, tied in the back of a person, should pose no threat.

Thanks For The Info Mr. John
