[0002] Insulating sheets are commonly used inside existing electronic products, especially in the front and rear (FRONT & REAR) areas, to provide electrical isolation and prevent circuit short circuits. Insulating sheets can be made of different materials, the most common of which are high-temperature-resistant and chemical-resistant materials such as polyimide (such as Kapton) or polyvinyl alcohol. FRONT: The front insulating sheet is mainly used to shield areas such as the display interface and power button to prevent external electrical interference. REAR: The rear insulating sheet is mostly used to protect the motherboard and power supply, isolate sensitive components on the motherboard, and avoid short circuits or accidental damage during heat dissipation. The current insulating sheet structure protective film is double-layered, which is expensive and easy to fall off during the assembly process, causing the PSA double-sided tape to be exposed, thus affecting performance.
