I wear one on my ankle.
Do i need a anti static building mat and wristband.
Make sure you have one hand or your forearm touching some metal part of the case while working.
I am a field tech and have never carried around a mat or strap.
This is an elastic band made of conductive fiber such as carbon or carbon filled rubber that are bounded on the hand with a stainless steel plate or clasp.
I alwyas build mine on the carpet floor while sitting down and i never use an anti static wristband even though i know i should.
There s pretty much no reason not to own one.
You do not need an anti static mat or wrist strap.
Dude an esd safe mat with a grounding cable and a wristband costs like 30.
Unless 30 40 is really gonna cause some problems you might as well own one.
I am very careful though and a perfectionist so i handle each piece.
Just take the other necessary precautions.
However having the mat and the wrist strap grounded at the same point does keep them in electrical balance.
The wristband works by redirecting the static discharge through a cord which then follows an antistatic mat or another grounded conductor to the ground.
Here are some more details about anti static wristband.
It is best to have it plugged up and unplug the power connector off the motherboard.
By redirecting the static these wristband devices assist in properly grounding your body balancing out any electrical charge differences between you and electrical parts.
The grounding cable is what connects the anti static mat being used as a work surface to the electrical outlet.
