Thinner-gauge EFR 735 film can replace thicker FRPP film without sacrificing performance. At gauges as thin as 0.006 in. it equals the performance of 0.017-in.-thick FRPP. Thinner gauges give designers greater flexibility to create today’s flatter, lighter-weight notebook PCs and other devices. They also help to reduce material costs through down gauging.

U.S. and European agencies continue to tighten regulations on EMI/RFI emissions. Effective shielding solutions include metal boxes, conductive paints, plating, metal chassis and conductive polymers. However, these methods add significant cost and unwanted weight to electronic devices. EFR 735 film provides a low-cost, lightweight solution to both primary shielding and secondary (problem area) shielding, while maintaining Electronics Transformer. Laminated to a conductive foil, such as copper or aluminum, this high performance-insulating film allows creatively designed shields to be placed in close proximity to the emitting source, without fear of internal arcing. Using this material for die-cut insulators and spacers can give manufacturers greater fabrication ease and compatibility advantages with many fastening and laminating adhesives.

Ease of Fabrication

EFR 735 film provides easy fabrication using processes including thermoforming, embossing, clean-edge die cutting, scoring and bending. The product, in a matte/velvet finish, is available globally in 0.006 in., 0.010 in., 0.017 in., and 0.025 in. gauges.
