Hi all,

After bad experiences during PC and radios repairing I decided to solve my ESD protection in the kitchen "lab" property.

I would like to share my experiences with ESD mats for safe, ESD protective soldering as it can help to others. I looked for long time on the eBay and other shops for possibility to purchase small portable ESD mats including the cables to connect for same el. potential or directly to common ground.

All mats which I found were big and expensive or small but expensive or small, not high quality just vinyl and expensive etc. Requested parameters were: two layers, oil, grease and solvent resistant, high temp resistant, acid proof and knife cut proof material.

After long time I returned back to Czech market where I found the company where they has exactly what I looked for but unfortunately the mats was too big. Standard size is 80cm x 160cm for high price dedicated for professional industrial usage. So I tried to call them and after some negotiation they promised to cut it for me to preffered size 40x60cm and install the cables and bananas for ground connection.

We also reached after some phone calls negotiation an excellent price.

Parameters:

- thickness: 2mm

- RTG = 10^6 – 10^8

This branded R2 Ultra/Antistat ESD Rubber Mats have two layers; the top one is a blue static dissipative rubber layer laminated to a black conductive rubber bottom layer. Surface resistivity of the top layer is 10^6 – 10^8 and bottom layer is 10^5 – 10^6. This ESD Rubber material offers excellent resistance to oil, grease and most common solvent. These ESD Rubber Mats are very light compared to single layer and three layer mats.

After ordering and arrival at home I decided to make several tests:

Several oils, greases and different solvents and mat survived without any damages.

The flare-up point and it seems to be higher than 1000 C which is corresponding to almost 2000 F. (I was limited by temp sensors and thermometer over here)

The burning thru temperature and it survived 450 C for 2mins which is

corresponding to 850 F. (I was limited by my soldering station, hi)

The max of the temp without any noticeable damage of the top layer. It survived 200 C for 2mins which is corresponding to 400 F.

Finaly I tried to cut it using standard knife and make the hole thru using drill and it proved very high resistance.

The complete set including the 60x40cm high durability ESD mat, grounding snap points, wristband, coiled wires including the 1MOhms resistors to limit the current, banana socket and aligator clip. The set is ready to use. I never had any ESD issues with this protection when i repaired PC, radios etc.

All these tests results are so great that I am really happy with this new ESD mat and I am sure that it will make great job.

RESUME:

To get best price from supplier we ordered with local friends higher amount of the sets so I have rest of them available for sale. If You would like to get this ESD mats also then let me know OFF-LIST to indians@xsmail.com

I am ready to help You with purchasing, repacking and shipping to you worldwide.

Hope it will help to some of You as same as to me with safe soldering in the kitchen property...

Sorry for a bit longer message and bothering other people but I guess it can help to many of us with ESD issue.
