Abstract

The invention discloses a multipurpose wave absorbing film which comprises a PET insulation layer, a composite metal layer, a wave absorbing layer and a release material layer. A first adhesive layer is disposed between the PET insulation layer and the composite metal layer. A second adhesive layer is disposed between the composite metal layer and the wave absorbing layer. The composite metal layer is overlapped by a copper layer and an aluminum foil layer. The surface, contacting with the wave absorbing layer, of the composite metal layer is provided with a plurality of first prism protruding parts and second prism protruding parts, the first prism protruding parts are higher than the second prism protruding parts, and the first prism protruding parts and the second prism protruding parts are arranged alternately. A third adhesive layer, a polypropylene film layer and a fourth adhesive layer are sequentially disposed between the wave absorbing layer and the release material layer. The multipurpose wave absorbing film has the advantages that by the composite metal layer, multi-time absorbing can be formed, tape wave absorbing performance is increased evidently, heat dissipation is facilitated, film upwarp caused by temperature rise is avoided, and product performance stability is increased.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, in particular to a multipurpose wave-absorbing film. Background technique [0002] The development of the electronics and communication industry is advancing by leaps and bounds, and more and more electronic and electrical products have entered the lives of ordinary people. While these products improve people's quality of life, they also bring about a prominent problem, that is, the problem of electromagnetic radiation. The electromagnetic waves released by electronic products will bring electromagnetic interference to other electronic devices around them, making them work abnormally; at the same time, they will also cause harm to human health. [0003] At present, miniaturization and high integration are the mainstream trends in the development of electronic products, and the internal space of these products is relatively small. Among the wave-absorbing materials, the chip-type wa...
