ESD Kapton Tape

Description

ESD Kapton Tape (ESD Polyimide Tape) is manufactured from high-performance polyimide film treated with an antistatic surface coating and coated with a single-sided high-temperature silicone pressure-sensitive adhesive. The PI base film provides excellent electrical insulation, chemical resistance, and dimensional stability, while the antistatic surface treatment keeps the surface resistivity within a controlled ESD-safe range suitable for electronics manufacturing.

The tape maintains strong adhesion during high-temperature processes such as reflow and wave soldering, yet removes cleanly without residue, greatly reducing the risk of electrostatic discharge damage to sensitive electronic components. It is widely used for PCB gold finger masking, SMT reflow protection, lithium battery insulation and fixing, and high-temperature masking applications in electronics assembly.

Features

• High-temperature resistance: Withstands up to 260 °C (500 °F), ideal for reflow soldering and wave soldering processes.
• Controlled antistatic performance: Surface resistivity typically in the 10⁶–10⁹ Ω/sq range (model-dependent), ensuring low charge generation and safe handling of ESD-sensitive components.
• Low charge generation during peeling (test-method dependent): Designed to reduce peeling/unwinding voltage under controlled test conditions; results vary with speed, humidity, substrate, and adhesive grade. Test reports are available upon request.
• High-performance silicone adhesive: Strong adhesion during heating; clean removal with no residue.
• Ultra-thin & clean appearance: Common total thickness approx. 0.06 mm, easy to cut, punch, or die-cut into custom shapes.
• Excellent solvent, chemical, and electrical insulation performance.
• Substrate compatibility: Adheres well to common metals and plastics. For low-surface-energy materials (e.g., PP/PE) or fluoropolymer surfaces (e.g., PTFE), application-specific testing is recommended to confirm required bond strength.

Applications

• PCB manufacturing: Gold finger protection, SMT masking, reflow and wave soldering processes requiring ESD-safe high-temperature shielding.Supports ESD control programs (e.g., ANSI/ESD S20.20) as part of an overall static control plan during masking and handling of ESD-sensitive devices.
• Battery manufacturing: Insulation and fixing of lithium battery electrodes; protection against electrolyte influence.
• Motor & coil insulation: Used in motors, transformers, coils, inductors, and high-temperature electrical insulation systems.
• Electronics assembly & repair: High-temperature masking, component protection, and ESD-safe temporary fixation.
• General high-temperature and antistatic environments: Suitable for a wide range of industrial masking and electronic protection tasks.
• ESD-sensitive handling & fixtures: Temporary protection and masking for ESD-sensitive carriers, fixtures, and workholding in electronics processes where static control is critical (validation recommended for specific workflows such as wafer-related operations).

FAQS

Q1:Can ESD Kapton tape withstand high-temperature soldering processes?

Yes. ESD polyimide tape is typically rated up to 260°C (500°F). Performance depends on the reflow profile and dwell time; please verify under your process conditions.

Q2:Will the tape leave adhesive residue after high-temperature use?

High-quality silicone-adhesive ESD polyimide tapes are designed for clean removal with minimal residue on common smooth substrates when removed within the recommended temperature/time window. Residue can vary with substrate, dwell time, and process temperature; trials are recommended for critical surfaces.

Q3:What is the surface resistivity range of ESD Kapton tape?

Most ESD-treated polyimide tapes are in the 10⁶–10⁹ Ω/sq range (model-dependent). Values can vary with humidity, contamination, and test method, so refer to the SKU datasheet.

Q4:Is ESD Kapton tape safe for use with sensitive electronic components?

Yes. It is specifically designed for low electrostatic charge generation during peeling or unwinding, reducing the risk of ESD damage to semiconductors, microchips, and other sensitive components.

Q5:What standard tests are used to verify performance?

Common reference tests include:

• • ASTM D257 – Surface resistivity

  • ASTM D3330 – Peel adhesion

  • ASTM D3759 (tape) or equivalent method – Tensile / elongation

  • Peeling/unwinding voltage test (method available upon request)
