EMC ESD problems
Posted: Wed Jun 03, 2015 5:08 pmPIC32MX460F512L
I develop some different products using the microcontroller PIC32MX460F512L. All the products are affected by problems with the ESD discharge test EN 61000-4-2.
When arrive a discharge, the microcontroller perform a reset. It happen also using a coupling plane near to the microcontroller, without allow to the discharge to direct arrive to the board.
On the board are present a Transil on the 3V3 and all the requested ceramic capacitor.
It's not easy to solve the problem because there isn't a particular problematic pin, the ESD arrive only at the external test plane.
Any Idea or official guide about this ESD problem ?
