3M 7000123303 Pcb Tape 851 Green 2in X 144yd 4.0 Mil

Product Description

The 3M 7000123303 is a translucent green polyester film tape engineered for printed circuit board plating and masking applications. Built on a 1 mil polyester film backing with a heavy coat weight silicone and rubber blended adhesive, it delivers consistent conformability over board edges, plating masks, and irregular surfaces. Total tape thickness is 3.6 mil, with a rated 4.0 mil overall callout. The adhesive system is selected for clean removal after plating processes without leaving residue that could affect circuit integrity. This tape is handled and applied by electronics assembly technicians and PCB fabrication specialists.

This tape is intended for use in PCB plating masking workflows, including through-hole plating, selective plating, and wave solder masking in both prototype and production environments. It performs in the controlled conditions typical of electronics fabrication facilities. The 2 inch width and 144 yard roll length make it suited for continuous production runs where consistent coverage and minimal roll changes matter. It is not intended for general industrial masking or outdoor applications.

Key Features

• 1 mil polyester film backing provides dimensional stability during plating processes
• Heavy coat weight silicone and rubber blended adhesive for strong conformability
• 3.6 mil total thickness with clean removability after plating
• Translucent green color for visual inspection and process verification
• 2 inch width by 144 yard roll length supports high-volume production use

Compatibility

Designed as an OEM-style masking tape for use in printed circuit board plating and selective masking processes in electronics fabrication and assembly applications.

Installation Notes

Application is typically performed by PCB fabrication technicians or electronics assembly personnel. Boards should be clean, dry, and free of flux residue or contamination before tape is applied to ensure proper adhesion and seal. Tape should be pressed firmly along edges to prevent plating solution migration under the mask. Remove tape promptly after the plating process is complete and before adhesive dwell causes bonding changes to the substrate.
