ESD Protection for K3 Assembly

Hi all,

I received my K3 kit yesterday and am setting up to start assembly. I bought an ESD mat and a wrist band. I was wondering what I should connect the alligator clip from the wrist band to, for best protection?

Thanks,

Jay (KD6AMA)

Jay most have a snap on them that snaps to the one on the mat like it. Then
the mat attaches to the ground.

Re: ESD Protection for K3 Assembly

I connect mine to my station ground... If there is zero lightning!

Sent, as to how? Who cares!

Re: ESD Protection for K3 Assembly

The important thing is that you and the device you are working on are at the
same potential (voltage). When you place the device on the anti-static mat,
it will be at the mat potential. So you should connect your wrist strap to
the mat. Most wrist straps have a snap that connects to a matching snap on
the mat.

It is also important that the soldering iron be at the same potential as any
device you are soldering with it. Assuming the soldering iron is grounded
to the electrical system safety ground, then the mat should be connected to
ground as well.

Re: ESD Protection for K3 Assembly

In reply to this post by Phillip Lontz

Phil,

Connection to the AC ground should be adequate and safe - if a
receptacle is properly grounded, remove the screw in the center of the
cover plate and attach a terminal lug there.

If your station ground is connected by a heavy guage wire to the Utility
Entry ground point, then I will agree with your that the station ground
will do.

We all know that there are references to "station ground" that are
connected to driven ground rods that are NOT connected to the Utility
Entry ground.

I need to point out that not only is that a violation of NEC
grounding requirements, but it presents safety hazards for anyone in
contact with that station ground under AC wiring fault conditions. All
grounds must be connected together except for structures separated by
100 feet or more.

See the 2010 (or later) ARRL Handbook for further information.

I apologize if this sounds like a rant, but it is not - it is concern
for the safety of each and every ham.

73,
Don W3FPR

Re: ESD Protection for K3 Assembly

Thanks Don... Yes indeed...all my grounds are connected to each other via big fat ass cables.

Sent, as to how? Who cares!
