3M 7000048434 Pcb Masking Tape 851 Green 1in X 144yd 4mil

Product Description

The 3M 7000048434 is a polyester film masking tape engineered for printed circuit board plating processes. Built on a 1 mil polyester film backing with a heavy coat weight silicone and rubber blended adhesive, the tape delivers strong conformability over board surfaces and component edges. Total tape thickness is 3.6 mil, translucent green in color, and wound in a 1 inch wide by 144 yard roll. The combination of film backing and blended adhesive holds cleanly through plating bath exposure and resists adhesive transfer on removal. PCB assembly technicians and electronics production professionals are the primary users of this tape.

This tape is used in printed circuit board manufacturing and rework environments where precise masking is required during electroplating, wave soldering preparation, and related chemical processing steps. The translucent green film allows technicians to verify coverage and alignment without removing the tape. The 144 yard roll length supports high-volume production runs and reduces changeover frequency on masking stations. It is suited for both automated taping operations and hand-application in bench-level PCB work.

Key Features

• 1 mil 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
• Translucent green color allows visual verification of masking coverage
• 1 inch width by 144 yard roll length for extended production runs
• Designed to resist adhesive transfer and hold cleanly through chemical exposure

Compatibility

Designed for use in printed circuit board plating and masking applications where a conformable polyester film tape is required.

Installation Notes

Application is performed by electronics assembly technicians and PCB production personnel. Surfaces should be clean, dry, and free of flux residue or contamination before tape is applied to ensure proper adhesion and seal. Apply with firm, even pressure to eliminate air pockets along masked edges. Remove tape promptly after processing per process guidelines to minimize residue risk.
