Description

TECHNICAL FIELD

[0002] Circuit board withstand voltage test is one of main methods to test the ability of circuit board to withstand overvoltage, to ensure the safety and reliability of circuit board. This test assesses the electrical performance of circuit board by applying a high voltage to it and monitoring whether the insulating part of the circuit board breaks down. Withstand voltage test usually includes two types: leakage current test and withstand voltage test. Leakage current test is to test whether the insulating part of the circuit board can prevent current from passing through; withstand voltage test is to test the insulation performance of circuit board under high voltage, i.e. no breakdown under high voltage. This test is crucial to ensure the normal operation of electronic equipment, because circuit board is a key component in electronic equipment, and its stability and reliability directly affect the operation of the entire device, but the contact position of different circuit boards is different, and it is troublesome to adjust the power connection position when applying voltage.
