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.
Anti static label
Anti static label is a type of self-adhesive label with anti-static long-lasting acrylic pressure-sensitive adhesive and a white coating suitable for heat transfer printing. It is made of two materials: polyester and polyimide (with high temperature resistance), and is designed specifically for printed circuit boards or related electronic components that require reducing static electricity to be labeled with characters or barcodes.
Among them, high-temperature and anti-static labels are ideal materials that can withstand the erosion of various fluxes, melting agents, and cleaning agents encountered in the production process of various circuit boards. Kaiyu Electronics uses anti-static adhesive and anti-static coating that are resistant to static electricity (the material can self transfer and release static electricity), leaving only a small amount of static electricity on the label in a very short period of time. The use of adhesive backed anti-static labels reduces the static electricity generated by tearing off the label from the backing paper to a safe level without damaging electronic components that are highly sensitive to static electricity.
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.
