What is 3m9079?
3m9079 is a transparent, double-sided adhesive tape without a carrier (substrate), specifically engineered for high-temperature environments like those required in lead-free soldering processes. With the ability to endure heat up to 260°C and low outgassing, it is ideal for flexible circuit bonding and other sensitive electronic applications. The tape offers high bonding strength, clean processing, and stable performance under thermal stress.
Composition and Structure
- Adhesive type: High-temperature-resistant acrylic adhesive
- Color: Transparent
- Construction: Substrate-free (adhesive transfer tape)
- Release liner: Heat-resistant paper that can withstand reflow soldering
- Thickness: Not specified, but engineered for tight tolerances in high-precision electronic applications
Key Properties
- High heat resistance up to 260°C, suitable for lead-free soldering processes
- Maintains strong adhesive performance even after exposure to reflow soldering
- Low outgassing/volatility for clean and stable performance
- Excellent bonding strength for FPC, stiffeners, and frames
- Easy die-cutting for high-precision application shapes
- Reliable adhesive stability over time
Applications of 3m9079
- Electronics: Bonding FPC (flexible printed circuits), stiffeners, and frames in high-temperature soldering processes
- Mobile device assembly: Used in compact electronics requiring thin and heat-resistant adhesive layers
- Automotive electronics: Securing high-temperature components in tight engine or cabin spaces
- Aerospace: Bonding parts where flame resistance and heat durability are critical
- Other high-temperature assemblies: Any application requiring a clean, strong, and temperature-resistant bond
Features & Benefits of 3m9079
- Withstands 260°C, ideal for lead-free soldering and reflow processes
- Reduces contamination and improves product reliability through low volatility
- Transparent finish maintains aesthetics and visibility
- Die-cuts easily for complex designs or mass production needs
- Maintains bonding integrity after thermal cycles or shocks
