Don't know if it will help but here are some key things you need for ESD protection:-
Human induced ESD
- Wrist straps + monitors when strap is not grounded.
- Ground mat (Earthed)
- Static protective overcoats
Work environment
- cleanliness: Keep ESD sources (paper, plastics etc) away from work area
- ESD warning labels.
- Training. All users must know ESD handling procedures.
- Hummidiers. (drier the air, higher charge build up).
- Equipment. Make sure it has grounding and cannot leave to a CDM event
- Static bags.
Not related to ESD but whilst we are talking protection on rework, make sure you take appropriate moisture handling protection measures for your electronic componets. If not, any moisture inside the device will expand upon soldering and could damage the device.
