Process and ESD Protection


What should be paid attention to during the ESP32 ESD test?

  • The Electrostatic Discharge (ESD) test for ESP32 is conducted to ensure that the device has sufficient tolerance to withstand electrostatic discharge. The precautions are as follows:

    • ESD testing should be conducted in an ESD laboratory or ESD protection area, which should have good grounding protection and electrostatic discharge protection facilities.

    • When conducting ESD testing, please use ESD testing equipment that meets international standards, including ESD generators and ESD grounding mats, to ensure the accuracy of the test results.

    • When conducting ESD testing, please make sure you are using a stable 3.3 V voltage. If the EN trace is too long, it may cause a reboot.

    • ESP32 devices should be tested multiple times to verify the reliability of their tolerance, and the test results should be recorded and analyzed.

    • If the module does not respond, please check the voltage of the air discharge or contact discharge used in the test.
