RoHS Compliance Statement
None of the following materials are
intentionally added in manufacturing
this product: lead, mercury, cadmium,
hexavalent chromium, polybrominated
biphenyls (PBB) or polybrominated
diphenyl ethers (PBDE) as outlined in
the Directive 2002/95/EC Article 4.1. See
“Resistance-to-groundable point 1 x 10E6 to 1 x 10E9 ohms. Resistance from
point-to-point greater than 1 megohm. These guidelines represent a range of
resistance that has generally been proven to provide protection in the manufacturing
environment.” [ANSI/ESD S4.1 section 8. Resistance Guidelines]
“[Rtg is] The most important functional consideration for worksurfaces. This establishes
the resistance of the primary path to ground for items, placed on the surface. When
worksurface materials are being selected, consideration should be given to possible
Charged Device Model (CDM) damage to ESD sensitive products. If CDM damage is a
concern then setting a lower resistance limit for the worksurface should be considered.
Typically, the lower limit for these types of worksurfaces is 1 X10E6 ohms.” [ESD
Handbook TR20.20 section 5.3.1.7 Electrical Considerations]

Description
Desco’s Disposable ESD Mat meets ANSI/ESD S20.20 worksurface required limit and
recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. The
material is intended to be a sacrificial material to protect a more expensive
worksurfaces from damage caused by conformal coating, solder fluxes, or other
contaminates. The material is made from a 100% recyclable dissipative impregnated
worksurface material and has an internal conductive layer so that it does not generate
a static charge and will control the discharge rate from all conductors (including ESD
susceptible items) that are placed on the surface. The mat may be grounded by
placing it onto an already grounded ESD worksurface.
