5.5 ESD Notes
SIM7020 is sensitive to ESD in the process of storage, transporting, and assembling. When SIM7020
is mounted on the users’ mother board, the ESD components should be placed beside the connectors
which human body may touch, such as SIM card holder, audio jacks, switches, keys, etc. The
following table shows the SIM7020 ESD measurement performance without any external ESD
component.
