ESD, or electrostatic discharge, is of great concern to anyone who deals with electronics. That's obvious. What's not necessarily so obvious, is that some times, you don't even need to be all that close to the circuit board or component to damage it.
This article by Douglas C. Smith illustrates why sometimes, just a wrist strap isn't enough.
That's why we don't only use wrist straps, but also have a grounded conductive floor and use ESD jackets and conductive foot straps to protect the boards and components out on our manufacturing floor.
Here's a video showing the dreaded ESD monster and us protecting your gear from him:
Greased lightning is an interesting concept
Would it reduce power line transmission losses?
