3M 7000048690 Polyimide Film Tape 5413 Amber 1.5x36yd

Product Description

The 3M 7000048690 is a polyimide film tape used in high-temperature masking, protection, and fabrication applications across electronics manufacturing and related trades. It features a 2.7 mil polyimide film backing coated with a silicone adhesive, giving it strong resistance to heat, chemicals, and radiation. The tape is flame retardant and supplied in a 1.5-inch-wide by 36-yard roll. It is suited for environments where conventional plastic tapes fail under thermal stress. Electricians, PCB assemblers, and electronics technicians reach for this tape when standard masking materials cannot handle the process conditions.

This tape is primarily used to mask and protect the gold fingers of printed circuit boards during wave soldering and solder dip operations. It also serves as a release surface in fabrication setups where parts are cured at elevated temperatures. The combination of silicone adhesive and polyimide film allows the tape to survive high-heat curing cycles without losing adhesion mid-process or leaving residue on sensitive contact surfaces after removal.

Key Features

• 2.7 mil polyimide film backing with silicone adhesive for high-temperature performance
• Flame retardant construction for use in soldering and heat-curing environments
• Chemical and radiation resistant film for demanding process conditions
• Suitable for masking gold finger contacts on printed circuit boards during wave solder and solder dip
• Functions as a release surface for parts cured at elevated temperatures
• 1.5-inch width by 36-yard length per roll

Compatibility

Designed for use in printed circuit board assembly masking during wave solder and solder dip processes, and as a release surface in elevated-temperature fabrication and curing operations.

Installation Notes

Application is typically performed by electronics assembly technicians or electricians working in PCB fabrication environments. Ensure the bonding surface is clean and free of flux, oils, or contamination before applying the tape to achieve proper adhesion. Remove the tape carefully after soldering or curing to avoid lifting pads or contact surfaces. Follow your facility safety protocols and equipment manufacturer guidelines when working near solder baths or curing ovens.
