Case Assembly Component Assembly Nameplate Attachment Cover Attachment Small Parts Bonding Small Parts Bonding M Laminating Adhesive provides long-lasting bond performance and easy application. 3M Bonding Film combines hot melt speed and the precision fit of film to bond metal and plastic. 3M Plastic Bonding Adhesive 2665 sets like a hot melt adhesive but with long open time for assembly of parts requiring a thin bond line. 3M Adhesive 200MP Hi-performance Acrylic family, 3M VHB Tapes, and light cure adhesives provide excellent adhesion to plastic materials and good thermal shock resistance. Flex Circuit Assembly Aesthetics Flexible Circuit Interconnection Flexible Circuit Wear Protection Flexible Circuit Rigidizing Graphic Impact M Anisotropic Adhesive Films provide high adhesion and electrical conductivity for fine pitch display interconnect. For conformable, durable protection, 3M Polyurethane Protective Tapes cover flexible circuits with a tough surface. A variety of 3M Tapes are available with such features as high strength, Z-Axis conductivity or thermal conductivity. 3M Dimensional Graphics attach on contact and offer a choice of colors and textures in custom dimensions. Display Assembly Identification Display Screen Assembly Display Screen Protection Tracking Label Certification Label M Optically Clear Adhesive offers excellent clarity and adhesion for display screens and other applications requiring a see-through bond. 3M Protective Tape over the display helps prevent scratches and marring during assembly and shipping. Bar code on 3M Thermal Transfer Label Material stays accurately readable for the expected life of the component. 3M Laminating Adhesive bonds polycarbonate thermal transfer labels to equipment.

PC Card EMI Shielding Attachment PC Card Label PC Card Assembly Die-Cut EMI Shielding EMI Shielding Tape Durable 3M Thermal Transfer Label Materials identify PC cards. Protection Surface Protection 3M Bonding Film makes a high strength bond in seconds with heat for assembly of stainless steel lids to connectors and plastic frames. Lid cushioning Die-cut 3M Electrically Conductive Adhesive Transfer Tapes allow small, thin shields in tight areas, or large easy-to-apply shields. Also provide excellent adhesion for insulator attachment. Water Contact Indication 3M Foil Tapes help shield incoming and outgoing EMI. Easy application. Long term aging. Tamper Indicating Warranty Label Before After M Bumpon Protective Products bond on contact to the base and help protect work surfaces from scratches. To mute and cushion lid closing, custom-shaped 3M Bumpon Protective Products attach to the inside of the lid with light thumb pressure. 3M Water Contact Indicator Tape changes from white to red after wetting to assist warranty claim resolution. 3M Destructible Vinyl Label Material shows tampering and makes label non-transferable. Thermal Management Thermally-conductive Potting. Low viscosity 3M Thermally Conductive Epoxy readily covers and permanently stabilizes components while providing a thermal path for heat dissipation. Process Solutions Personal Service, In-depth Expertise Anywhere in the world, you can rely on 3M for support in applications engineering that includes product evaluation and equipment feasibility and sourcing.
