In order to make the laser power of flexible printed circuit (FPC) board laser drilling equipment in domestic industry real-time monitoring, stable and dynamic adjustment, an embedded power monitoring and automatic control method based on domestic GD32 chip as the core was adopted. Theoretical analysis and experimental verification were carried out. The results show that the mean squared error of the fitted line between the set power of the laser and the actual monitoring power is less than 0.05626, and the laser power fluctuation is less than 2%. The results show that the method is feasible for FPC laser drilling equipment.
