Method, equipment and system for marking test result of circuit board

The invention relates to the field of marking, and particularly relates to a method, equipment and a system for marking a test result of a circuit board. The method comprises the steps of: determiningwhether conveyed circuit boards are qualified or not according to a detected circuit board test result; detecting whether an unqualified circuit board in the conveying process reaches a preset position or not; stopping conveying the circuit board when the circuit board reaches the preset position; generating a distribution diagram of unqualified points on the circuit board according to a test result of the circuit board; and carrying out unqualified point marking on corresponding positions on the circuit board according to the distribution diagram. The method, the equipment and the system avoid radiation damage to marking personnel caused by circuit board detection equipment in the existing marking, facilitate next maintenance for the maintenance engineers after the unqualified circuit board is marked, achieve au
