Static electricity issue: The microcontroller (MCU) may experience program crashes or crashes due to ESD breakdown. The coupling of electrostatic pulses to the power line can cause system reset or data loss, and the electrostatic adsorption of dust can block the device's heat dissipation holes, leading to overheating and shutdown.
Solution: SMT patch lines are equipped with ion fans to eliminate static electricity accumulation during PCB processing. Real time warning of electrostatic risks is achieved through electrostatic sensors.
