What do I clip my ESD mat to if no power supply or metal table?

The ifixit video for the ESD mat instructs the user to clip to a metal component of their work table, but I'm working on a wooden kitchen table. It does have small metal brackets underneath to hold an expansion piece, but it would be very hard to clip to them.

The one answer I found here mentions clipping to the ground on a wall socket, but I don't have one near my table and that sounds like a recipe for disaster as I don't know enough about electronics to avoid posting this question.

I have also read that I should clip to the bare metal of the pc case or power supply I'm working on, but I'm going to be upgrading old Thinkpads, so that's not really an option.

I have two potential options:

- a metal lamp, painted, that is plugged in. Though that isn't a three prong plug so I don't know if that counts.

-I could also borrow my old man's desk. It's in a carpeted room and is fully enameled, but it does have a metal frame. Could either of these work?

Any suggestions or feedback are appreciated!

If you want to connect it to the metal chassis of anything that plugs into the wall (lamp, computer, PS etc.), it has to be plugged in with a three-prong plug. Otherwise, you are not connected to earth ground. One easy way to get around this issue is to create your own ground plug. Just go to the hardware store, buy a DIY three-pronged plug and run a wire (16AWG/18AWG is fine) from the ground plug and solder it to the lug on your mat.

Or you can also buy one of these.

Minho, thank you for this answer. One of the products in your link is a 15' grounding cable that ends in a metal loop that appears to fit around the metal screw of a wall receptacle plate. As I don't have a solder kit yet, I think this might be my best bet for ensuring ground. Of course, I'm assuming this is a common solution and these receptacles are designed to have the middle screw act as ground. I won't get shocked, hopefully! :)


You'll be fine!



I'm not sure where to start here. Let's see if I have this right, you have a work bench with no electricity to it.

Solution: Get another bench and place where you do have electricity. You are going to need power for the objects you are working on. Just clipping onto metal won't cut it. A ground actually has to have continuity with the ground, be that the ground wire in an electrical outlet a water pipe, like a radiator. Walking on carpet builds static electricity and just 1/10 the amount you get when you get a little static shock will fry electronic components. Read the guide on ESD so can understand it.

the convenient thing is on ifixits ESD wrist band, the alligator clip can be removed, and whats left is something you can just insert into the ground prong of an outlet.


Mayer, thank you for your response.

I do not have a "work bench". I have a kitchen table that is quite far from a wall receptacle. I am not sure how to explain further, if that isn't clear.

I also live in a small grad apartment and will not be able to buy furniture for these repairs. Regrettably, no proper work benches are in my immediate future.

"Just clipping onto metal won't cut it." Please expand on this, as this statement runs counter to ifixit's ESD video which can be found on the anti-static mat's product page.

"You are going to need power for the objects you are working on."

My repair instructions state that my laptop should never have power, so I don't understand why you are stating I will need this.
