This is accomplished by providing concise minimum requirements, performance limits for those requirements, test references, and an audit system that insures proper implementation. EIA 625 is divided into 12 sections. Sections 1 through 3 deliver the usual boilerplate about what the document covers, who should use it, and where to get referenced publications. EIA 625 applies to a broad audience including Semiconductor Manufacturers, Distributors, Processors, Device Users, including board level production and handling. Unfortunately, no guidance is given about how testing for this value should be accomplished.
Packaging is required to provide electrostatic shielding and limit tribocharging.
This means that an Unprotected ESDS device is a device that is not placed in ESD-protective packaging. Inspection Items that require checking and the frequency of that inspection are detailed in a table. Wrist straps and footwear must be checked daily and personnel visually inspected to ensure their use. Weekly visual inspections of work surfaces for cleanliness and ground wire connections are required. Work surfaces, flooring and wire must be tested quarterly.
