Ultimat CR White Static Dissipative Work Surface (Cleanroom / Precut Mat)

In a typical electronics EPA (ESD Protected Area), the goal is straightforward: manage charge and discharge paths so sensitive devices are protected. In cleanroom and controlled environments, the goal becomes dual-purpose: you still must manage static, but you also need discipline around materials and housekeeping so you do not introduce avoidable contamination risk at the bench.

That is why products like Ultimat CR White are positioned differently than standard mats. The published intent is not only ESD performance, but also low-outgassing behavior and cleanroom compatibility characteristics that matter when yield, optics, or particulate sensitivity is in scope.

Many work surfaces behave acceptably when new, then drift over time due to wear, residue, or cleaning practices. The published description for Ultimat CR White emphasizes a chemically cross-linked material with volume dissipative / volume conductive behavior through the material layers. Practically, this positioning is about stability: a mature ESD program tries to reduce “unknown variability” at the bench.

This is also why cleaning discipline matters. A cleanroom bench mat should be treated as a controlled element of the EPA: approved, installed consistently, maintained, and verified.

ESD programs that align to ANSI/ESD S20.20 and IEC 61340-5-1 succeed when they operate as systems: defined control items, defined grounding methods, consistent training, and documentation. ESD TR53 reinforces verification expectations—controls must be checked at a practical frequency so performance does not drift.

The operational takeaway is simple: the mat is not a control because it exists. It is a control when it is grounded correctly, kept clean with compatible methods, and periodically verified.

• Ground intentionally: use a known-good ground point and the correct ground cord. Do not rely on assumptions.
• Respect published monitor limitations: if you use continuous monitors, confirm installation method and bench construction (published note: stainless steel tops may be required).
• Use visual controls: white bench surfaces improve visibility for small components, FOD control, and cleaning confirmation.
• Maintain the surface: residue management and compatible cleaning methods reduce drift and support repeatability.
