3M 7000050136 Polyimide Film Tape 5413 Amber 5/8in X 36yd

Product Description

The 3M 7000050136 is a roll of 3M Polyimide Film Tape 5413 in amber, measuring 5/8 inches wide by 36 yards long with a total thickness of 2.7 mil (0.07 mm). The tape consists of a polyimide film backing coated with a silicone adhesive. It is flame retardant and resistant to chemicals and radiation, making it suited for demanding thermal and process environments. Electronics technicians, PCB assemblers, and manufacturing process engineers are the primary users. The tape holds up to elevated cure temperatures while maintaining adhesion and dimensional stability.

This tape is commonly used in printed circuit board manufacturing and electronics assembly. Its primary application is masking gold fingers on PCBs during wave solder or solder dip operations, preventing solder contamination on connector contact areas. It also serves as a release surface in mold and fabrication processes where parts are cured at elevated temperatures. The amber polyimide film is a standard material for high-temperature masking in electronics production environments.

Key Features

• 2.7 mil (0.07 mm) polyimide film construction for high-temperature resistance
• Silicone adhesive system designed for clean removal after thermal processing
• Flame retardant formulation suitable for wave solder and solder dip masking
• Chemical and radiation resistant for demanding process environments
• Functions as a release surface during elevated-temperature part curing

Compatibility

Designed for use in PCB masking applications during wave solder and solder dip processes, and as a release surface in fabrication of parts cured at elevated temperatures.

Installation Notes

Application is performed by trained electronics assembly or process technicians. Ensure the bonding surface is clean, dry, and free of contamination before applying the tape. Apply with firm, even pressure to prevent air entrapment or edge lifting during thermal processing. Remove the tape carefully after processing to avoid damage to adjacent components or surface finishes.
