Problems solved by technology

[0002] With the rapid development of society, various adhesive tapes have become indispensable items in the electronics industry; in the electronic product industry such as mobile phones, notebook computers, tablet computers, and digital cameras, they can be used for fixing flexible circuits and frames. However, Ordinary adhesive tape is often used, which does not have the functions of electric conduction, heat conduction, shock resistance, and shielding, which affects the performance of electronic products
[0003] The conductive and thermally conductive tapes used in the market are generally made of conductive and thermally conductive substrates coated with conductive and thermally conductive adhesives. As a result, the use effect of the prepared conductive tape is not ideal; the foam used in the anti-seismic tape is relatively soft, and its tensile performance is very poor. Die-cutting and punching are easy to deform during use, resulting in dimensional changes
[0004] These tape products have single performance and cannot meet the needs of the rapid development of the electronics industry. Therefore, it is necessary to develop an aluminum foil conductive, thermally conductive, shock-resistant, and shielding tape.
