The function of anti-static labels
-
Rapid release of static electricity upon peeling, and the swift reduction of static electricity inhibits damage to electrostatic sensitive components.
-
Minimizing the residual resistance of the adhesive.
It is generally considered that a range of 1011 ohms falls within the anti-static scope, effectively protecting sensitive components from breakdown, and the peeling voltage should not be excessively high.
Another aspect is the peeling voltage, which should be less than 100V. An excessively high peeling voltage can also impact sensitive components. Traditional self-adhesive labels can generate static electricity up to 1000V when peeled from the backing paper.
Moreover, being insulating by nature, they may retain electrical charge for a long time before returning to a neutral state.
Advantages of anti-static labels
Protection of electrostatic sensitive components: The main advantage of anti-static labels lies in their ability to effectively prevent damage to sensitive components caused by static electricity, ensuring product stability and reliability.
Improving production efficiency: By reducing electrostatic discharge (ESD) incidents, anti-static labels help minimize failures and downtime during the production process, thereby improving production efficiency.
Enhancing product safety: In flammable and explosive environments, static electricity can trigger fires or explosions. Anti-static labels can reduce this risk, enhancing product safety.
Characteristics of anti-static labels
Anti-static materials: Anti-static labels are typically made from materials with anti-static properties such as polyester (PET) and polyimide, which exhibit good physical and chemical stability.
Rapid electrostatic discharge: The label surface is coated with an anti-static coating or adhesive, enabling the label to quickly discharge electrostatic charges when peeled off from the backing paper, thereby reducing potential threats to electrostatic sensitive components.
Good weather resistance: Anti-static labels can maintain stable performance under various harsh environments, including high temperature and high humidity conditions.
Easy identification and tracking: Anti-static labels usually feature clear markings and coding, facilitating product identification and tracking, and improving management efficiency.
The difference between anti-static labels and regular labels
The main difference between anti-static labels and ordinary labels lies in their materials, functions, application scenarios, and performance requirements.
In terms of materials, anti-static labels use polyester (PET), polyimide and other materials with anti-static properties, and may be coated with anti-static coatings or adhesives to quickly release static electricity. However, ordinary labels use a wider range of adhesive materials such as paper, PET, PP, etc., which do not have anti-static properties.
Functionally, the main purpose of anti-static labels is to prevent damage to sensitive components caused by electrostatic discharge, and may also have identification and tracking functions. Ordinary labels are mainly used for product identification and tracking, providing basic information.
In terms of application scenarios, anti-static labels are widely used in the electronic and electrical industry, especially in environments that require prevention of electrostatic damage, such as printed circuit boards, integrated circuits, etc. Ordinary labels are suitable for a wider range of products and scenarios.
In terms of performance requirements, anti-static labels have higher requirements for their conductivity, adhesion, temperature and humidity resistance, chemical corrosion resistance, etc., to ensure stable operation in harsh environments and effectively prevent static damage. The performance requirements for ordinary tags are relatively low, mainly focusing on the implementation of their identification and tracking functions.
