I have to say that I am very satisfied with my Nescaf filter. For its simplicity
the performance is great and it comes to be my favourable toy.
After bad experiences with esd sensitive parts soldering I decided to solve my ESD protection in the kitchen "lab" a bit better...
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 I found were big and expensive or small but expensive or small, not
high quality 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 are 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 and negotiation an excellent price for the complete set.
- thickness: 2mm
- RTG = 10^6 – 10^8
The superior quality R2 Ultra/Antistat ESD mat 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 material offers excellent resistance to oil, grease and most common solvent.
These R2 Ultra Mats are very light compared to 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
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.
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
I am ready to help You with shipping to you worldwide.
...and one more think
Sorry for a bit longer message and bothering other people but I guess it can
help to many of us with ESD issue and hope it will help to some of You as same as to me with safe soldering in the kitchen property...
