LED basic knowledge of the EOS
What is EOS?
EOS for the Electrical Over Stress acronym referring to all the excessive electrical stress. When the external current or voltage exceeds the maximum specification conditions for the device, the device performance will be weakened or even damaged.
EOS are usually arise from
1. Power Supply (AC / DC) interference, power supply noise and over-voltage.
2. As the test program switch (thermal switch) results in the transient current / peak / low frequency interference. The process duration may be a few microseconds to a few seconds (it may be a few nanoseconds), very short pulses of EOS and ESD damage caused similar damage.
3. Lightning.
4. Test program switch caused by transient / glitches / short pulse interference.
5. Poor test design, for example, the device power-up or has not yet exceeded the ceiling of its operation to the device under test signal to send. Another example of the power supply before the device test signals, or exceed the maximum operating conditions.
6. From the pulse signal interference with other devices that send pulses from other devices.
7. Improper work practices, work flow is not reasonable
8. Then point the anti-hop (due to take place fast enough |
