3M 7000123312 Circuit Plating Tape 1280 Red 2in X 144yd 4.2 Mil

Product Description

The 3M 7000123312 is a red polyester film circuit plating tape designed for precision masking of printed circuit boards during electroplating operations. The tape measures 2 inches wide by 144 yards long and carries a 4.2 mil total thickness. It uses a silicone and rubber blend adhesive that holds cleanly against board surfaces through plating bath chemistry without leaving residue. The polyester film backing provides dimensional stability under process conditions. Electronics assembly technicians and PCB fabrication shops rely on this tape to protect areas that must remain unplated during selective electroplating cycles.

This tape is suited for printed circuit board masking in both production and rework environments. It is applied before parts enter electroplating baths and removed cleanly after processing is complete. The red film color provides easy visual confirmation of masked zones during inspection steps. Typical users include PCB fabricators, electronics manufacturers, and specialty plating operations requiring reliable, repeatable masking performance on fine-pitch board layouts.

Key Features

• 4.2 mil total tape thickness provides a robust moisture and chemical barrier during plating
• Red polyester film backing allows clear visual identification of masked areas
• Silicone and rubber blend adhesive bonds securely and removes cleanly without adhesive transfer
• 2 inches x 144 yard roll format supports high-volume production masking runs
• Polyester film construction maintains dimensional stability under electroplating bath conditions

Compatibility

Designed for use as a masking tape on printed circuit boards during electroplating processes. Suitable for selective plating applications where defined board areas must be protected from plating chemistry.

Installation Notes

Application is typically performed by electronics assembly or PCB fabrication technicians. Ensure board surfaces are clean and dry before applying tape to achieve proper adhesion and edge seal. Apply firm, even pressure along all tape edges to prevent plating solution from undercutting the masked area. Remove tape promptly after processing and before adhesive dwell time causes bond strengthening that could complicate clean removal.
