An electrostatic discharge (ESD) test evaluates the durability of electronic devices against an electrostatic discharge event, which can occur, for example, when a person touches them.
In winter, when you touch a doorknob or try to get out of a car, you may feel a "buzz" of static electricity discharge. This is caused by a person's body being charged. In this way, when a charged conductor such as the human body comes into contact with or approaches another conductor, a violent discharge occurs.
This phenomenon is called electrostatic discharge (ESD) and is not a problem if the object generating the discharge is a doorknob or the like, however, if the discharge occurs to an electronic device, it can cause malfunctions or even permanent damage.
However, in our daily lives, we cannot completely prevent electrostatic discharge. For this reason, electrostatic discharge testing is used to evaluate if electronic devices can withstand an ESD event. This is done by applying controlled electrostatic discharges to components, such as LEDs and semiconductors, to determine if they are damaged or fail.
ESD testing involves applying very fast, high-voltage pulses to the device under test. To generate these pulses, a capacitor is charged to a specific voltage and then rapidly discharged, which creates the required pulse.
Matsusada Precision supplies the high-voltage power supplies needed to charge the capacitors used in ESD testing equipment.
Our high voltage power supplies are used for electrostatic discharge experiments.
