The charge transfer caused by objects with different electrostatic potentials approaching each other or in direct contact.
ESD is a common near-field hazard source, which can form a high-voltage source, arc electric field, and instantaneous large current, accompanied by strong electromagnetic radiation, forming an electrostatic discharge electromagnetic pulse.
Current>1A
Rise time ~ 15ns, decay time ~ 150ns
Electrostatic discharge has mechanical effects, thermal effects, strong electric field effects, and electromagnetic pulse effects, which will have a great impact on smart door locks, causing damage to components and abnormal functions.Electrostatic damage is concealed, potential, random, and complex, causing incalculable losses to enterprises and production. Therefore, to avoid this loss, adequate anti-static measures must be taken.
1. Media isolation
2. Shielding
3. Grounding and bonding
4. Others such as the use of ESD protection devices, etc.
