Anti-static wrist band for in-house PCB assembly?
Hi all,
We're doing some light PCB finalization in our office and we're having some challenges/risks related to static shocks.
We were thinking if there's an anti-static wrist band we could use during production.
Does anyone have experiences with using these - and whether there are specific types that work better than others?
E.g. how to handle the grounding in practice in-doors?
Looking forward to your thoughts,

ESD control is a very broad topic, and there are many books written on the subject.
Any static discharges that a person can feel as a "shock" are far into the danger area for CMOS components. Even insensible discharges can kill chips, especially prior to soldering. Wrist straps are one component of an ESD solution, but don't neglect ESD work pads, ESD component boxes and bags, shoe straps and/or floor treatments if components need to be carried from one workstation to another. ESD monitors are also recommended to provide quick feedback for any failures in the protective devices.
Also consider humidification if your work area is dangerously low in relative humidity, below 20-30%RH.
Simply as a starting point, which may or may not be enough in your particular situation, you can wear a 3M or other major brand (ACL, Desco) wrist strap and clip it to the ground lug of your soldering station. This would be about the minimum protection to consider.
