3M™ Embossed Copper Foil Shielding Tape 1245 has a 1.4-mil embossed copper foil backing with acrylic pressure-sensitive adhesive and liner. Embossing makes excellent contact through the adhesive. The unplated copper is for non-corrosive conditions.
Features and Benefits
Dead soft 1-ounce (1.4-mil) copper foil backing for good shielding effectiveness, soldering and converting (slitting and die cutting).
UL recognized flame-retardancy per UL 510 for applications needing this property.
Embossed pattern through adhesive provides very low contact resistance between the substrate and the backing to drain static charge.
Acrylic pressure-sensitive adhesive has good resistance to heat, oxidation, solvents and oils.
Removable liner makes it easy to handle and die cut complex shapes.
There are both standard and custom roll widths and lengths to meet a variety of application needs.
Commonly used for RFI/EMI (radio-frequency interference or electromagnetic interference) shielding and ESD (electrostatic discharge) grounding for components, integrated circuits, connectors, cables, motors, equipment enclosures/cabinets and shielded rooms.
Conductive circuit or bus bar for low voltage applications
Used in jobs requiring high conductivity or shielding effectiveness for a given thickness.
Best used in non-corrosive environments.
The 1245 tape has common EMI shielding 1.4-mil thick copper foil backing. Acrylic adhesive has good resistance to heat, oxidation, solvents and oils. The tape is UL Recognized for flame retardancy per UL 510. This tape is designed for a variety of applications: point-to-point electrical contact, EMI/RFI shielding, grounding and static charge draining. These tapes can used in both electronic & electrical devices, shielded rooms and EMI test laboratories for prototyping, design and troubleshooting. The 1245 tape is available from 3M in log rolls (standard size of 23 inch x 18 yds or 584 mm x 16,5 m) to 3M slitter/converters. Also, 3M offers to 3M authorized distributors (and slitter/converters) various size slit rolls for resale to end users. Custom die-cut and formed parts are available from 3M slitter/converters.
