3M 7000050099 Polyimide Film Tape 5419 0.25in X 36yd

Product Description

The 3M 7000050099 is a low static polyimide film tape — sold as 3M Tape 5419 — designed for electronics manufacturing and high-temperature fabrication applications. The tape features a translucent polyimide film backing coated with a silicone adhesive and is engineered with extremely low electrostatic discharge (ESD) properties. At 2.7 mil total thickness, it delivers reliable masking performance while minimizing static buildup that can damage sensitive electronic components. Each roll measures 0.25 inches wide by 36 yards long. Licensed electricians, electronics assembly technicians, and PCB fabricators are the primary installers and users of this tape.

This tape is used in two primary applications. First, it serves as a masking tape for printed circuit boards (PCBs) during wave solder or solder dip processes, where its low static properties protect sensitive components from electrostatic damage and its silicone adhesive withstands the elevated process temperatures. Second, it functions as a release surface in the fabrication of parts cured at elevated temperatures, where clean removal without residue is critical. It is well suited for electronics production lines, prototype assembly, and repair environments.

Key Features

• Extremely low electrostatic discharge properties protect ESD-sensitive PCB components during soldering
• Polyimide film backing rated for high-temperature performance including wave solder and solder dip processes
• Silicone adhesive system compatible with elevated-temperature cure cycles and release-surface applications
• Translucent backing allows visual inspection of masked areas during assembly
• 2.7 mil total tape thickness provides a thin, conformable profile for precise masking
• 0.25 inches x 36 yards per roll format suitable for manual or dispenser application on production lines

Compatibility

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

Installation Notes

Apply in clean, dry conditions to ensure proper adhesion and static-control performance. Power down and discharge any sensitive electronic assemblies before applying or removing tape in ESD-controlled environments. Remove tape promptly after the solder or cure process completes to minimize adhesive interaction with substrates. Follow your facility ESD handling protocols and any applicable IPC standards when working on PCB assemblies.
