Golden Finger Tape (polyimide tape) is a precision material widely used in electronics, battery manufacturing, and other high-tech industries. To maximize its effectiveness, knowing how to select the right tape and store it properly is crucial.

1. How to Choose the Right Golden Finger Tape?
When selecting polyimide tape, consider these key factors:
🔥 Temperature Rating
• Ensure the tape can withstand your manufacturing process temperature, typically 260°C for continuous use and up to 300°C short-term.
🧴 Adhesive Type
• Silicone adhesive offers better heat resistance and residue-free removal compared to acrylic adhesive.
🎯 Thickness and Dimensions
• Choose thickness based on application: thinner tapes (0.05mm) for precise insulation; thicker ones (0.1mm+) for mechanical protection.
• Width and length should fit your production equipment and usage.
⚡ Electrical and Chemical Properties
• Verify the tape’s dielectric strength and chemical resistance to prevent short circuits and corrosion.
🛡 Certifications
• Check for RoHS, REACH, UL94 flame retardant certifications to ensure compliance and safety.

2. Best Practices for Storing Golden Finger Tape
Proper storage maintains tape quality and prevents premature aging:
• Temperature: Store in a cool, dry place between 15°C and 25°C. Avoid high temperatures above 30°C.
• Humidity: Keep humidity levels between 40% and 60%. Excess moisture can degrade adhesive properties.
• Sunlight: Avoid direct sunlight or UV exposure, which can damage polyimide film and adhesive.
• Positioning: Store tapes upright on shelves or racks to avoid deformation or pressure marks.
• Shelf Life: Generally, shelf life is 12 months under ideal conditions. Use FIFO (first-in, first-out) inventory management.

3. Handling Tips
• When applying tape, ensure the surface is clean, dry, and free of oils.
• Use proper cutting tools to avoid uneven edges or adhesive contamination.
• Avoid overstretching tape to maintain adhesive strength.
