The Applied Technical Services Family of Companies’ (FoC’s) provides comprehensive SEMI F47 voltage sag testing services to verify that your equipment can withstand voltage dips and continue operating through specified voltage sag conditions. Power quality disturbances are one of the leading causes of unexpected equipment shutdowns in semiconductor manufacturing environments. By validating compliance with the applicable SEMI F47 standard revision, we help protect your processes, productivity, and profitability.
Why Electrical Equipment Must Withstand Voltage Sag Events
SEMI F47 voltage sag testing evaluates how semiconductor processing, metrology, and automated test equipment respond to controlled voltage sag events. The testing standard establishes minimum ride-through requirements at specific voltage levels and durations, helping ensure tools do not shut down or misoperate during common power disturbances.
Even brief voltage sags can result in wafer scrap, tool resets, production delays, and significant financial losses. Performing this testing can help reduce these risks by confirming that your equipment meets industry-accepted power immunity criteria before it enters service, or after modifications are made.
Our Testing Capabilities
ATS uses advanced programmable power sources that simulate precise sag depths and durations in accordance with SEMI and applicable IEC test methodologies. Our experts evaluate full systems and individual subsystems, including:
- Semiconductor fabrication tools
- Process and metrology equipment
- Power supplies and control panels
- PLCs, drives, and automation systems
- Single-phase and three-phase equipment
Applicable Industries and Environments
While primarily required in semiconductor manufacturing facilities (fabs), SEMI F47 voltage sag testing can also be essential for:
- Semiconductor equipment OEMs
- Microelectronics manufacturers
- Advanced manufacturing facilities
- Power quality and utility support teams
- Research and development laboratories
Many fabs require documented compliance as part of procurement and supplier qualification processes. ATS helps semiconductor manufacturers meet testing requirements with confidence.
