I had problems following the links. I went to Amazon and searched for Bertech Rubber ESD
and there you go........ all kinds of choices.
Thanks Bill for that info, used these years ago but here in Florida especially during the summer there’s not much static if you’re shop isn’t air conditioned!! I may get the 18 x 24 one for my winter projects.
If you need a parachute and don't have one you probably won't need one again.

Hi there,I sensed that there was a bit of confusion regarding ESD mats and I would like to clarify a few things, if I may. BTW, I work at an electronics equipment factory and I wear an ESD wrist wrap and an ESD lab coat when writing and verifying the testing procedures for our products.The Craft E Mat may be good as a work bench protector and components gathering device, but it is not ESD compliant.Here you have an example of a true ESD mat:https://www.amazon.com/Bertech-Temperature-Rubber-Wrist-Grounding/dp/B01KT3YPPS/ref=sr_1_1_sspa?crid=WH16OYYVTSYC&keywords=esd+mat+kit+with+a+wrist+strap+and+grounding+cord&qid=1555363698&s=gateway&sprefix=ESD+mat%2Caps%2C200&sr=8-1-spons&psc=1In any event, ESD compliant mats and wrist straps are only necessary when working with ESD sensitive devices, such as MOSFET transistors, computer ICs, RAM memory sticks, some LEDs (laser and UV), and CMOS ICs. Most TTLICs and bipolar transistors are quite resilient to ESD. For the most part, when the ESD sensitive devices are soldered or connected to the PCB, they become more resilient to ESD. When the PCB carrying those devices is connected to the rest of the equipment, only some I/O ports may still be ESD sensitive.ESD compliant mats have a high-resistance top layer that dissipates static electricity by sending it to a ground connection. This ground can be the ground terminal of a nearby ac socket or a dedicated low-resistance earth ground rod. The wrist strap works in a similar fashion.73!Original email:-----------------From: wohlsson . wohlsson@...Date: Sun, 14 Apr 2019 21:00:45 -0400To: firstname.lastname@example.orgSubject: Re: [4SQRP] Anti Static soldering matsOpps...forgot the linkhttps://www.amazon.com/Craft-Mat-Oversize-Worry-Silicone/dp/B07GBFRCJY/ref=sr_1_1?keywords=craftemat&qid=1555288975&s=gateway&sr=8-1Bill...wa8bda<https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon>Virus-free.www.avast.com<https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link><#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>On Sun, Apr 14, 2019 at 8:58 PM wohlsson . via Groups.Io <email@example.com> wrote:
Yes, these silicone mats are nice for bench work/kit building. I have been
using the one
below now for a few months. Grand kids orginally bought one for craft
projects and I was
attracted to the large 1/2" sides to contain things. Also the large
working area allow me to
also place test equipment/tools on the work area and still have lots of
space. I use a anti-static
wrist band when needed.

We have rolls of material that look similar at work. They cut it to size
for the work area but then the corner gets punched and a snap terminal
installed which has a lead connecting it to ground.
I've been starting to look for a small anti-static mat for my home bench
and these that were mentioned look nice since they have the raised edge
help keep things from escaping.

want ESD protection with your body, you can use it with an anti static

Any idea if these mats are anti-static as well?

I met some of you guys at Ozarkcon and had a great time! I hope I can
make it back next year.
During the kit building Joe and I were using these nifty blue silicone
soldering mats. I think there will be something on them in April CQ.
Anyway I was asked to provide information on them here. I actually head
about them from Bob Heil on Ham Nation. Apparently Heil Sound has started
using them. They are used by technicians to repair cell phones and small
electronics but they work great for building kits! They are good for ESD
and aren't affected by hot solder. They also have magnets that will hold
little parts in place until they are needed. The magnets also help the
stick to a cookie sheet!
And I got them on Amazon!
Kaisi S-140 magnetic insulation soldering mat
They come in several sizes. The S-140 fits perfect in a medium steel
cookie sheet from Wal Mart! And I find that when it gets overrun with
leads and solder blobs you can clean it off with a piece of masking tape.
And if you need to move your work just pick up the cookie sheet. Also the
silicone makes for a nice quiet work surface.
Hope this helps everyone have even more fun building stuff!
Hope to see some of y'all in Dayton.
