ESD is usually caused by HBM (Human-Body Model), MM (Machine Model), CDM (Charge d-Device Model) and FIM (Field-Induced Model). The advantages of preventing ESD in the factory include better product reliability, extended usage life, cost savings and increased yields.
In order to ensure that the products will not be affected by ESD during production, an ESD control procedure is in place to meet standards.
Wear anti-static suits and wrist straps in the factory.
Each device and working area is grounded and tested periodically to confirm that the ESD measurement is normal.
