ESD / EOS
What is EOS?
What is EOS?
EOS stands for Electrical Over Stress.
EOS is the term for stress that exceeds the rated voltage/current. In other words, EOS occurs when the voltage or current exceeds the values guaranteed by the IC.
EOS is fatal for semiconductors, causing irreversible damage to the hardware. It influences Metal Lines, and usually causes Open and Short failures.
The main causes of EOS are: low-quality Power Supplier, Power Off during testing, and operating methods that are not standardized during Board Testing.
The Pulse period is long compared to electrostatic energy (within units uS~mS).
