Hello experts and everyone’s invited to this answer:
Could you provide examples of isolated conductors? (Knowing the technical rule is a conductor that measures >=1x10e9ohms from contact point to ground)… what are those ‘isolated conductors’ at your job places?
Thank you
Santiago,
Basically, an isolated conductor is a conductor in your process that, for some reason, you are not able to ground. Some examples are any special tool or fixture that is not groundable like a multimeter, torque wrench, etc. I am sure others can come up with other examples. Thanks.
Santiago,
In addition to what Andy has noted, some of the most common isolated conductors used consist of hand tools.
Types of hand tools include, but are not limited to, unpowered screwdrivers, wrenches, pliers, cutters, vises, clamps, snips, saws, drills, knives, solder dispensers, tweezers, nut drivers, torque wrenches, wire strippers, wire cutters, and syringes (used in staking type operations0
Hand tools may be comprised of various insulative, dissipative, and conductive materials. Both ends of the tool (tip and handle) and the continuity between them helps to characterize the potential ESD risk to the ESDS item.
The ESDA has a working group (WG13) that is currently working on a Technical Report that will detail how to properly test these types of tools for process characterization for use in ESDS situations.
AndyN and MattS, Thank you very much!!
