3M 7000050064 Polyimide Film Tape 5413 Amber 0.25in X 36yd

Product Description

The 3M 7000050064 is a polyimide film tape designed for high-temperature masking and protection applications in electronics manufacturing and industrial fabrication. The tape features a 2.7 mil polyimide film backing coated with a silicone adhesive, delivering strong adhesion alongside flame retardancy and resistance to chemicals and radiation. It is commonly used by electronics assembly technicians, PCB manufacturers, and industrial fabricators who require a reliable masking solution that holds up under extreme thermal and chemical conditions. The roll measures 0.25 inches wide by 36 yards long.

This tape is primarily used to mask and protect gold fingers on printed circuit boards during wave solder and solder dip processes, preventing solder contamination on contact areas. It also serves as a release surface in the fabrication of components cured at elevated temperatures, making it a practical choice in aerospace, electronics, and industrial manufacturing environments where thermal stability is critical. The silicone adhesive system is engineered to perform at process temperatures typical of wave soldering operations without leaving residue on sensitive surfaces.

Key Features

• 2.7 mil polyimide film backing with silicone adhesive for high-temperature performance
• Flame retardant construction suitable for soldering and curing processes
• Chemical and radiation resistant for use in demanding industrial environments
• Designed for PCB gold finger masking during wave solder and solder dip operations
• Functions as a release surface for parts cured at elevated temperatures
• Amber color aids visual identification during masking and inspection

Compatibility

Designed for use in wave solder, solder dip, and elevated-temperature curing processes; suited for masking gold fingers on printed circuit boards and as a release liner in high-temperature part fabrication.

Installation Notes

Application is typically performed by electronics assembly technicians or fabrication specialists. Ensure the substrate surface is clean and free of oils or contaminants before applying the tape to achieve full adhesive contact. Remove the tape promptly after the soldering or curing process is complete to minimize adhesive interaction with the substrate. Follow all applicable workplace safety protocols when working near soldering equipment or elevated-temperature curing ovens.
