ESD (Electro-Static discharge) means "electrostatic discharge". ESD is formed since the mid-20th century to study the generation of static electricity, hazards and electrostatic protection and other disciplines. Therefore, the international custom will be used for electrostatic protection equipment collectively referred to as ESD, the Chinese name for the electrostatic resistance.

Use the instrument:

Static gun

ESD tests are divided into two types:

1, air discharge

2, contact discharge

The same time as

The discharge voltage varies depending on the product or the requirements.

Test results are divided into four categories:

A: Apply static and negative static electricity with an electrostatic gun, the product is not affected by it and work normally.

B: with static guns to apply positive and negative static electricity, the product is only a small impact, and also work properly.

C: with static guns to add positive and negative static electricity, the product crashes, with manual recovery when you can work properly.

D: with static guns to add positive and negative static electricity, the product can not work directly, manual recovery can not work properly.

General products in the A and B class is calculated through.
