Desco Statfree T2 Plus Dissipative Dual Layer Mat Kit (66425) vs Bertech ESD High Temperature Mat Kit (2059T Series)
Which should you buy? Our verdict on both, pulled from our full The Best ESD Mats: 4 Compared (and One to Skip) comparison.
Desco publishes per-layer resistance figures, cites the worksurface standard by name, and builds the mat from a nitrile rubber compound its own documentation says can be used with flux and solder. Bertech gets very close for less and adds two things Desco does not put in the box: an independent lab test report and a wrist strap.
Desco Statfree T2 Plus Dissipative Dual Layer Mat Kit (66425)
Buy itA dual-layer nitrile rubber worksurface with per-layer resistance figures published against the worksurface standard, sold as a kit with a ground cord and hardware.
- Publishes a dissipative top layer of 1 x 10^6 to less than 1 x 10^9 ohms point to point and a conductive bottom layer under 1 x 10^6 ohms.
- Desco states the nitrile rubber oil-resistant compound may be used in soldering applications with flux and other chemicals.
- The conductive underside lowers resistance to the groundable point, which is what lets the surface be used with a workstation monitor.
- The kit includes a grounding cord with hardware and a sample of mat cleaner, but no wrist strap, so personal grounding is a separate purchase.
- Costs several times what a consumer bench mat costs for a comparable footprint.
- Rubber this thick does not roll up neatly, so it is a bench fixture rather than something you take to a job.
Bertech ESD High Temperature Mat Kit (2059T Series)
Buy itA two-ply rubber mat kit that ships the mat, a wrist strap and a ground cord, and is backed by an independent test report measured to the current worksurface test method.
- Bertech publishes an EOS/ESD Association Services product test report measured to ANSI/ESD STM4.1-2017, which concludes the samples meet ANSI/ESD S20.20-2021.
- The kit includes the mat, an ESD fabric adjustable wrist strap and a grounding cord, so the whole path is in one box.
- The datasheet lists 2 x 10^6 to 10^8 ohms point to point, 8 x 10^6 to 10^8 ohms to the ground point, and a charge decay time under 0.01 seconds.
- The published service temperature is 190 degrees F, so it resists a hot iron and dropped solder rather than being a heatproof rework surface.
- The datasheet quotes ranges rather than a single certified value, and the independent report covers three samples of the series rather than your mat.
- At 0.080 inches it is thicker than most consumer mats, which raises your working height slightly.
