Guarding your sensitive equipment from the ravages of static electricity can be daunting, especially if you have to outfit an entire team of engineers with static-safe materials. Knowing the requirements of your particular environment is the first step.
The second step? Know your dissipative mat. Whether you need it for the floor, table or workstation, make sure you understand its specifications—like RTG versus RTT. Do you know the difference?
Resistance to Ground (RTG) is the resistance from the mat to the ground point. It is the primary measurement for general auditing purposes. This measurement ensures your mat conducts a charge from a point on the surface to the ground point. The guideline in ESD STM-7.1 for RTG is 1×106 to 1×109 ohms. ANSI/ESD S-20.20 has an upper limit of <1×109 ohms.
Resistance to Top (RTT), also called Resistance to Point, is the resistance from one point on the mat’s surface to another, which is measured to help ensure consistent resistance. The ESD STM-7.1 guideline for RTT is >1×106 ohms.
When it comes to equipping your entire facility, staying on budget is also critical. Your third step is to shop All-Spec. All-Spec’s selection of ESD-safe benchtop and floor mats runs the gamut. And, at All-Spec prices, you can easily equip your team—and maybe a few others—with all the tools it needs to run smoothly.
