3.5. Static Protection
In the application of the module, due to the static electricity generated by human body static
electricity and charged friction between microelectronics, it is discharged to the module through
various ways, which may cause certain damage to the module, so ESD protection should be taken
seriously. In the process of R&D, production, assembly and testing, especially in product design,
ESD protection measures should be taken. For example, at the interface of the circuit design and
the points that are easily damaged or affected by electrostatic discharge, anti-static protection
should be added; anti-static gloves should be worn during production.
