RSA (Rear Sided Adhesive Tape) is a double-sided industrial adhesive tape applied from the rear side of components to securely attach display modules, display layers, touch panels, gaskets or protective covers. In industrial terminology it is also known as mounting or technical adhesive tape.
It enables quick, durable assembly without screws or clips, ensures even adhesion, compensates for minor surface irregularities and dampens vibrations. It can also be used in air bonding processes, where a small air gap is left between layers, and it helps protect display assemblies against dust and moisture.
In electronics, RSA is commonly used for attaching cover glass, securing displays to housings or fixing touch modules to bezels. The term is sometimes used interchangeably with DSA (Double-Sided Adhesive), although some manufacturers distinguish them by application. RSA tapes are thin, UV-resistant and designed to withstand temperature variations and adhesive aging, which makes them suitable for industrial, medical and outdoor use.
