552 results about "Adhesive bonding" patented technology

Adhesive bonding (also referred to as gluing or glue bonding) describes a wafer bonding technique with applying an intermediate layer to connect substrates of different types of materials. Those connections produced can be soluble or insoluble. The commercially available adhesive can be organic or inorganic and is deposited on one or both substrate surfaces. Adhesives, especially the well-established SU-8, and benzocyclobutene (BCB), are specialized for MEMS or electronic component production.

Paver pedestal for wind uplift protection

A paver pedestal system is a versatile solution for elevated outdoor flooring, commonly used in rooftop terraces, plazas, and green roofs. However, wind uplift poses a significant threat to the stability of such systems, especially in high-wind areas. To mitigate this risk, paver pedestal systems are designed with enhanced features, such as mechanical fasteners, perimeter restraints, and interlocking pavers. These features ensure that pavers remain securely in place during strong winds. Additionally adhesive bonding methods are sometimes employed to further stabilize the structure. By combining these design elements, modern paver pedestal systems offer effective wind uplift protection while maintaining easy installation, drainage efficiency, and aesthetic appeal. This approach not only safeguards against potential damage but also extends the lifespan of rooftop surfaces, ensuring durability and safety in varying environmental conditions.
