With the rapid development of science and technology, the integration of electronic devices is increasing, and the miniaturization and precision of PCBs and components have become the norm in the industry. However, this high degree of integration and miniaturization also brings a severe challenge - the potential damage of electrostatic discharge (ESD) to electronic devices and components. Therefore, the importance of electrostatic protection products in the production of the electronics industry has become increasingly prominent.

1. What is static electricity?

Static electricity is an electrical phenomenon caused by the separation of electric charges. The electric constant it generates is usually very large, so its electric field strength is also very large. In daily life, static electricity is quite common, such as hair being charged after friction, and hearing electric sparks when wearing synthetic clothes and then taking them off.

2. Why do electronic workshops need to prevent static electricity?

Static electricity can have a negative impact on the performance, lifespan and reliability of electronic components, such as burning them and causing component failure. Therefore, electronic workshops must take a series of measures to prevent static electricity. The specific reasons are as follows:

1. Static electricity discharge can damage electronic components

When static electricity discharge occurs inside electronic components, a high-energy current will be injected into the electronic components for a short period of time, causing them to burn or be damaged, thus affecting the quality and reliability of the product.

2. Static electricity will reduce product quality

Electronic products are very sensitive to static electricity. Excessive static electricity may interfere with electronic components, thereby reducing product quality.

3. Static electricity can cause product failure

The impact of static electricity on electronic products may not be apparent immediately, but long-term static electricity impact and accumulation can cause product failure, resulting in huge economic losses.

3. How to prevent static electricity

In order to ensure the tolerance of electronic components and the reliability of products, measures must be taken to prevent the generation of static electricity. The main measures are as follows:
◆ Use ion fans or ion wind rods to quickly neutralize static electricity, prevent static electricity pollution and damage, ensure the stability and safety of the working environment, simple and convenient installation, and low subsequent maintenance costs.
◆ Wear an anti-static wrist strap and ground to ensure that the static electricity between the operator and sensitive electronic components is effectively dissipated. The electronic workshop must maintain a reliable ground connection.

This will discharge any static electricity into the ground, protecting your electronic equipment from the effects of static electricity.

◆Use a ground wire. The ground wire is one of the most important tools for anti-static. It can be used to ground static electricity and effectively carry it underground.
◆Perform component repair or PCB manufacturing in an ESD safe and clean room environment to reduce potential damage to products caused by static electricity.
◆Use anti-static materials. The application of anti-static materials can effectively prevent and control static electricity and reduce the impact on electronic components. Use anti-static mats on the assembly line or workbench.

Ensure that static electricity can be dispersed and dissipated quickly.

◆ Require employees to wear anti-static clothing to further reduce the risk of static electricity damaging sensitive electronic components.
◆It is prohibited to use accessories and jewelry that easily generate static electricity in the EPA to reduce the accumulation of static electricity.
◆ Avoid operating electronic equipment in severe weather conditions such as thunderstorms to reduce ESD risks.
◆ Use anti-static bags to package and store electronic products to ensure their safety during transportation.
◆Lay anti-static flooring. Anti-static flooring is a special flooring material that can effectively control the generation and accumulation of static electricity and ensure the safety of equipment and personnel.
