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=1

In 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 TTL
ICs
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.

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

to

help keep things from escaping.

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

mat

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.

I would love to participate. I am OK at abt 12wpm. However, my 7122 xtsl is actually 7121.1. I have a second 7122 xtal that tests out at 7120. I have my Bayou Jumper. I might have my SDR Cube on shortly. It is all controlled but only puts out about 1 watt. X1M is good for 5 watts but the receiver is noisy.

I backed into the Sprint.
