3M 7000048385 Pcb Masking Tape 1.5in X 72yd 4.0 Mil Green

Product Description

The 3M 7000048385 is a polyester film masking tape engineered for printed circuit board plating and masking applications. It features a 1 mil polyester film backing with a heavy-coat silicone and rubber blended adhesive that delivers strong conformability over board surfaces and edges. Total tape thickness is 3.6 mil (4.0 mil with adhesive). The translucent green color allows for visual inspection during the masking process. This tape is sold by the roll and is handled by electronics assembly technicians and PCB fabricators working in controlled production environments.

This tape is used in PCB plating masking processes where precise coverage and clean removal are required. The silicone and rubber blended adhesive system provides reliable hold during plating baths and thermal exposure without leaving residue that could contaminate board traces or contact pads. It is suited for both manual and fixture-assisted masking workflows in electronics manufacturing and rework environments.

Key Features

• 1 mil polyester film backing for dimensional stability during plating processes
• Heavy-coat silicone and rubber blended adhesive for strong conformability
• 3.6 mil total tape thickness for consistent masking coverage
• Translucent green color allows visual verification of masked areas
• 72-yard roll length reduces changeover frequency in production settings
• 1.5-inch width suited for masking larger board zones and edge runs

Compatibility

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

Installation Notes

Apply to clean, dry board surfaces free of flux residue, oils, or contaminants before placing boards into the plating process. Ensure tape edges are firmly pressed down to prevent plating solution from wicking beneath the mask. Remove tape promptly after the plating cycle while the board is still at process temperature to minimize adhesive residue risk. Follow your facility safety and chemical handling procedures when working with plating bath chemistries.
