Abstract

Embodiments of the invention relate to the technical field of electronic products, and disclose a power protection device and a circuit board testing system. In the embodiments of the invention, the power protection device includes at least one programmable power supply and a processor; a control end of the programmable power supply is connected with the processor, a voltage input end of the programmable power supply is configured to connect to a first power supply, and a voltage output end of the programmable power supply is configured to connect to a circuit board testing device; and the processor is configured to control the programmable power supply to convert the voltage output by the first power supply into a step voltage and supply power to the circuit board testing device. The embodiments of the invention further provide the circuit board testing system. The embodiments of the invention solve the voltage overshoot problem caused by instantly turning on the power supply, avoid the damage to electronic components on a circuit board, improve the product yield and reduce the loss.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic products, in particular to a power supply protection device and a circuit board testing system. Background technique [0002] Electrical Over Stress (EOS) shock means that when the current or voltage applied to an electronic component exceeds the maximum design specification requirements that the electronic component can withstand, the performance of the electronic component will be weakened or even directly damaged. The phenomenon. For example, when the circuit board test device tests the circuit board to be tested, if the voltage of the circuit board to be tested exceeds its maximum withstand value, the function of the electronic components installed on the circuit board to be tested will be weakened or damaged, especially for the power supply environment. In places (such as factories), the probability of EOS impact is relatively high; therefore, how to reduce the E...
