Why use anti-static tape
The core value of anti-static tape is to eliminate the potential damage of static electricity to electronic components, especially in precision manufacturing, packaging and transportation. Its mechanism of action and application advantages are as follows:
1. Core protection value
Protect electrostatic sensitive devices
Electronic components (such as integrated circuits and chips) are susceptible to electrostatic discharge (ESD), and anti-static tape controls the surface resistance of the material (usually 10⁶–10⁹Ω), quickly discharges the electrostatic charge (electrostatic discharge time <0.5 seconds), and reduces the electrostatic voltage generated during operation to below 100V (ordinary tape ≥5000V), significantly reducing the ESD risk.
Build a complete electrostatic protection system
As a key component of an electrostatic safety workstation, it is used in conjunction with anti-static wrist straps, workbench mats, shielding bags, etc. to form a multi-level protection barrier to prevent static electricity from accumulating during manufacturing, packaging and transportation.
2. Key application scenarios
Electronic manufacturing and packaging
Used for circuit board packaging and chip fixing to prevent static electricity from damaging components during assembly due to friction;
Sealed packaging with anti-static plastic bags/shielding bags to ensure storage and transportation safety.
Special environment adaptation
It can still maintain a low static charge level in a low humidity environment (relative humidity 10%), and is suitable for high-demand places such as dust-free workshops;
High-temperature resistant tapes (such as polyimide substrates) can withstand high temperatures of 260°C and are suitable for welding, reflow soldering and other processes.
Warning and identification functions
Yellow or grid warning tapes have both electrostatic protection and regional identification functions, and are used for workshop floor division and dangerous area prompts.
Extension in other fields
In the automotive field, installing anti-static tapes can divert body static electricity, reduce driving discomfort and fire risks; industrial conveyor belts adopt anti-static design to prevent static electricity from adsorbing dust or interfering with equipment operation.
3. Technical principles and performance advantages
Material science support: The substrate (such as OPP/PET, copper foil, polyimide film) is treated with anti-static treatment, and conductive materials (such as nickel) are added to the surface to achieve directional charge conduction;
Reliable physical property guarantee: It has high viscosity, wear resistance, oil resistance, chemical corrosion resistance and other characteristics to ensure long-term stability;
Safety certification and compliance: Some products have passed SGS, RoHS and other certifications and meet the standards of the electronic manufacturing industry.
Summary
Anti-static tape has become a basic tool for defending against electrostatic hazards in the electronics industry through controllable charge discharge and material adaptability design. Its technical maturity, scenario diversity and performance reliability make it irreplaceable in improving product yield and ensuring production safety.
