What do you know about conductive shielding material die-cutting foam

1、 Description of conductive foam

9759彩票集团Wrap conductive cloth magnetic material on flame-retardant sponge and die cut it. After a series of treatments, it has good surface conductivity and can be easily fixed on the shielding device with adhesive tape. There are shielding materials available in different crosssectional shapes, installation methods, UL ratings, and shielding effectiveness.

Conductive foam can be divided into aluminum foil cloth foam, conductive fiber cloth foam, gold-plated cloth foam, carbon plated cloth foam, etc. according to their materials.

2、 Advantages of conductive foam

9759彩票集团1. Compliant with RoHS, the improved Zaxis resistivity can increase shielding effectiveness to over 90dB over a wide frequency range

9759彩票集团2. Suitable for thicknesses of 0.039 "(1mm), 0.060" (1.5mm), 0.079 "(2mm), 0.098" (2.5mm), 0.125 "(3.2mm), and widths up to 0.250" (6.4mm).

9759彩票集团3. Large compression range, capable of compressing up to 60% of the original thickness; It also has UL94 HB and V0 flame retardant ratings.

4. Suitable for various standard configurations, including D-subs, USB ports, IEEE 1394, SCSI, and RJ 11. (also applicable to thin sheets and rectangular shapes)

5. Can be cut into the desired shape; Punch cut I/O, rectangular pads, and panel pads can be supplied with or without conductive adhesive backing; The low residual deformation ensures the long-term performance of the product.

3、 Classification of conductive foam

9759彩票集团Conductive shielding materials can be divided into ordinary conductive foam, nickel plated copper conductive foam, gold-plated conductive foam, carbon plated conductive foam, tin plated conductive foam, conductive aluminum foil foam, conductive copper foil foam, all-round conductive foam, SMT conductive foam, I/O conductive foam liner, etc.

4、 Characteristics of conductive foam

9759彩票集团1. Its material is very light and can provide electromagnetic shielding performance, which dominates the static electricity protection performance of the product and also has high-quality mesh die-cutting.

2. The lightweight material reduces its surface impedance capability and is independent of environmental humidity

9759彩票集团3. Conductive cloth foam has excellent anticorrosion and antioxidation properties, fully meeting the needs of hightech enterprises such as optoelectronics, microelectronics, aviation, aerospace, communication, military, chemical and chemical industries for new antistatic materials.
