3M 7000048392 Pcb Tape 851 Green 1 in X 72 Yd 4.0 Mil

Product Description

The 3M 7000048392 is a polyester film tape engineered for masking in printed circuit board (PCB) plating processes. The tape features a heavy coat weight silicone and rubber blended adhesive that delivers strong conformability over board edges, traces, and irregular surfaces. Total thickness is 3.6 mil, with the film base contributing approximately 1 mil. The translucent green color allows technicians to verify coverage and alignment before processing. This tape is designed for electronics assembly and PCB manufacturing environments where clean removal and process-safe masking are required.

This tape is primarily used in PCB plating masking applications found in electronics manufacturing facilities, contract assembly shops, and electronics repair operations. It is suited for use where a conformable, chemically stable masking solution is needed during plating, wave soldering prep, or selective coating processes. Electronics technicians and PCB assembly specialists are the primary installers and users.

Key Features

• Polyester film backing for dimensional stability during plating processes
• Heavy coat weight silicone and rubber blended adhesive for strong conformability
• 3.6 mil total tape thickness for reliable masking coverage
• Translucent green color for easy visual inspection of coverage
• 1 inch width by 72 yard length roll for extended production runs

Compatibility

Designed for use in printed circuit board plating masking applications where a conformable polyester film tape with process-stable adhesive is required.

Installation Notes

Application should be performed by qualified electronics assembly technicians in a clean, dry environment. Ensure all board surfaces are free of oils, flux residue, and contaminants before applying tape to achieve full adhesive contact. Remove the tape promptly after the plating or processing step is complete to minimize adhesive transfer. Follow applicable IPC standards and facility process documentation for PCB handling and masking procedures.
