2560-600 PI Gold Finger Tape: Ultra-High Temperature Protection Expert with 600g Peel Strength

2560-600 PI Gold Finger Tape: Ultra-High Temperature Protection Expert with 600g Peel Strength

Product Overview

2560-600 PI Gold Finger Tape is a high-performance polyimide tape specifically designed for extreme high-temperature and high peel strength requirements. Made with premium PI (polyimide) film and silicone adhesive, it features excellent heat resistance, superior electrical insulation properties, and ultra-high adhesion strength, making it an ideal choice for PCB gold finger protection, wave soldering masking, and other demanding high-temperature applications.

Key Advantages

1. Ultra-High Temperature Resistance

Withstands temperatures up to 260℃. After 30 minutes at 260℃, the tape shows no shrinkage, no deformation, and no adhesive residue upon removal, with stable and reliable performance, suitable for more demanding high-temperature process environments.

2. Ultra-High Peel Strength

Steel plate peel strength reaches 600±120g/25mm, providing higher adhesion strength compared to 2550 PI (550g/25mm), ensuring extremely strong adhesion even in high-temperature and high-humidity environments, no edge lifting or falling off.

3. Excellent Electrical Insulation

Voltage resistance reaches 5KV, providing good electrical insulation properties, suitable for insulation protection of electronic components, ensuring safe and reliable circuit operation.

4. Outstanding Mechanical Strength

Tensile strength reaches 135N/25mm, with excellent tensile resistance and dimensional stability, not easy to break in high-speed automated production.

5. Good Holding Power

Holding power ≥72 hours, initial tack ≥22# steel ball, ensuring stable adhesion effect even in long-term high-temperature environments.

6. Precision Thickness Control

Total product thickness 0.06±0.004mm, with PI film thickness of 0.025±0.002mm and silicone adhesive layer of 0.035±0.002mm. Precision thickness control ensures product performance consistency and stability.

Application Fields

  • PCB Gold Finger Protection: Protects gold fingers from oxidation, contamination, or damage during wave soldering, reflow soldering, and other high-temperature processes
  • Wave Soldering Masking: Used for local masking of PCB boards to prevent solder contamination of non-welding areas
  • Reflow Soldering Protection: Protects sensitive components and areas during high-temperature reflow soldering
  • Electronic Component Fixing: Used for temporary fixation of electronic components during SMT processes, does not fall off at high temperatures
  • Coil Winding Insulation: Used for winding insulation protection of motors and transformer coils
  • Transformer Insulation: Provides reliable electrical insulation protection, voltage resistance 5KV
  • Other High-Temperature Insulation: Widely used in electronics, electrical appliances, telecommunications, automotive, aerospace, and other industries
