Portable ESD worksurface that can also be used to transport populated but unsoldered circuit boards Static dissipative foam (RTT 1x10⁴ to < 1x10¹¹ ohms) laminated to Protektive Pak corrugated Foam is shuntable so board leads can be kept at equipotential Includes 10mm (3/8") female grounding snap Lightweight, thin, yet durable Fits most transportation carts Impregnated corrugated material; greater durability than coated or printed material. Static dissipative surface resistance of 1 x 10⁶ to < 1 x 10⁹ ohms per ANSI/ESD STM11.11 Buried shielding layer minimizes sloughing and rub-off contamination. It is made from 100% recycled material, 100% recyclable, and made in the United States of America.
