Ultra-Thin Double-Sided Adhesive Tape

In the high-stakes world of smartphone manufacturing, the battle for space is a critical factor in determining the success of a design. With advanced features like wireless charging systems, which entail a complex stack of materials such as copper foil, graphite flakes, nanocrystalline, and coils, the need for an ultra-thin, high-performance adhesive solution is more crucial than ever. Traditional double-sided tapes, with their considerable thickness, can negatively impact the performance of these materials, necessitating a novel solution.

The compact design of smartphones necessitates a consideration of the thickness of the double-sided tape used in their assembly, making it a critical factor. Adhesive transfer tape initially appeared to be an ideal solution, given its slim design and strong adhesion properties. Nevertheless, it has been discovered that this type of tape can cause multiple issues during mass production, making it ill-suited for use in high-volume manufacturing processes.
