What is ESD?
ESD stands for electrostatic discharge. Large differences in potential (different voltages) cause a short circuit of current - in the form of sparks or breakdown.
Depending on the voltage this phenomenon can occur in different ways.

I. What is ESD?
- ESD stands for electrostatic discharge. Large differences in potential (different voltages) cause a short circuit of current - in the form of sparks or breakdown. Depending on the voltage this can occur in different ways.
- Sensitive (from 3,000 volts)
- Audible (from 5,000 volts)
- Visible as sparks (from 10,000 volts)
- However, many discharges occur below the threshold of human perception, but can still cause damage - for example to electronic assemblies.
- For a person to feel a static discharge, it needs to reach about 3,000 volts. Meanwhile, 30 volts is enough to destroy a semiconductor cluster.
II. Causes of electric charge
- Static electricity occurs when electrical charges separate from each other. For example, when two different materials rub against each other or separate from each other. This often happens in normal everyday situations, such as walking on a carpet in plastic-soled shoes. This results in a predominantly negative charge spreading throughout the object or body being absorbed. If the object or body then comes into contact with another conductive object or is grounded, this charge will suddenly disappear.
- Some situations that can cause static electricity:
- Moving on the floor
- Friction with clothes during work
- Moving objects
- The phenomenon of static electricity can measure the decrease in humidity in the air, which is why the air humidity should be between 40% and 60%.
III. When is ESD dangerous?
- ESD does not generally pose any risk to humans. However, electrostatic discharge can be dangerous in manufacturing operations in the electronics industry.
- Uncontrolled electrostatic discharge can lead to complete failure or cause latent defects in electronic assemblies (semiconductor devices), which can lead to many other related damages such as:
- Defective product
- Complaints from users
- Repair and replacement costs
- Loss of Credibility
- Lost Customer
- In modern work areas, voltages in excess of 10,000 volts are quite common. Plastics are particularly susceptible to electrostatic charge, due to their high surface tension. For example, the surface potential of a typical plastic container can be as high as 20,000 volts – a risky environment for the electronic assemblies transported inside.

- ESD protected areas, also known as EPAs (electrostatic protected areas), provide effective protection against damage caused by electrostatic discharges. All antistatic equipment used must meet the minimum requirements of DIN EN 61340-5-1 and bear the antistatic symbol.
- PB SWISS TOOLS is a manufacturer of hand tools, assembly tools with a wide product range including some tools manufactured with antistatic properties for use in areas where static charges are permitted or in assembly lines of electronic devices (semiconductors) and PB SWISS TOOLS must also produce antistatic tools that meet the minimum requirements of DIN EN 61340-5-1 and carry the antistatic symbol.
