Hello. I'm in the process of upgrading my
electronics workbench to something more decently-built and equipped. I'm currently in the process of routing the power cables and strips, but I've also wanted to add a few points where an anti-static equipment like an ESD wristband can be attached. I'm curious to know what's the proper way that these things are wired and connected.
I've already bought a few items online, but they seem to be somewhat non-consistent. For example, I've bought three different ESD EBP's (earth-binding points) - these are mountable grounded sockets (studs) where anti-ESD wires can attach. Already I noticed a difference in the three.
Two seem to have parallel 1 MOhm resistors between the metal sockets and the earthing wire while the
third one does not - the multimeter shows a short on all sockets, and the studs aren't connected to anything. Then there are wires. Some
ESD spiral cables seem to have a built-in 1Mohm resistor themselves but I've also seen some anti-static cables that do not - I think my Ersa iCON soldering station had one like this. Finally, there's
the wristband that shows resistance in about 10 to 100 Ohms and
the antistatic mat that shows resistance in the MOhm range from the metal ESD pin to a random point on the bottom black layer. The top layer doesn't measure anything.
Now my question is: What's the correct way these things should be structured and wired? The ESD EBP's (ground cable) should obviously be grounded directly, but where should the 1 MOhm resistors be located ideally?
- Should EBP sockets have built-in 1MOhm resistors? Always or only in some cases? Which ones?
- Should ESD cables have built-in 1Mohm resistors? Always or only in some cases? Which ones?
Thanks in advance.
