5.8 ESD
Module is sensitive to ESD in the process of storage, transporting, and assembling. When module is
mounted on the customers’ main board, the ESD components should be placed closed to the connectors
which human body may touch, such as (U)SIM card socket, SD card socket, audio jacks, switches, USB
interface, etc. The following table shows the module ESD measurement performance.
