Key Elements of the ANSI/ESD S20.20 Standard
ANSI/ESD S20.20 outlines requirements for ESD control programs, including protection practices, hazard assessments, and verification processes to safeguard sensitive electronic components from static damage.
ESD Control Program Requirements
The ANSI/ESD S20.20 standard mandates the establishment of a comprehensive ESD control program to protect sensitive electronic components from damage caused by electrostatic discharge. This program must include the assessment of ESD hazards, particularly those posed by non-conductive materials in the workplace, to ensure appropriate protective measures are implemented. Initial and periodic verification of ESD flooring systems is required to maintain compliance with the standard. Additionally, the program must address the transportation of ESD-sensitive devices outside of an ESD Protected Area (EPA), requiring their enclosure in static protective materials. The standard also emphasizes the importance of limiting voltage on isolated conductors to below 35 volts to prevent static discharge. Compliance with these requirements ensures the safeguarding of electronic components and maintains the integrity of manufacturing processes in the electronics industry.
Practices for ESD Protection
ANSI/ESD S20.20 outlines essential practices for ESD protection, including grounding of personnel and equipment to prevent static buildup. The use of wrist straps and anti-static clothing is recommended to discharge static electricity safely. ESD-sensitive devices should be handled in an ESD Protected Area (EPA) with controlled humidity and conductivity. Tools and materials used in the EPA must be ESD-safe to minimize static generation. Regular testing of ESD control elements, such as flooring and workstations, ensures compliance with the standard. Additionally, the standard emphasizes proper packaging and transportation of ESD-sensitive items using static-protective materials. These practices collectively create a robust system to mitigate ESD risks and protect sensitive electronic components during manufacturing and handling.
Specific Requirements and Guidelines
