<p>Surface-mount techniques primarily depend on soldering. However, soldering techniques have encountered some challenges in recent years. The reflow process in electronic assembly needs high-temperature processes, which result in undesired thermal damages and residual stress at a bonding interface. Therefore, there is an urgent requirement to attach electronic parts to circuit boards with good mechanical and electrical properties at room temperature. We recently developed a metallic nanowire surface fastener (NSF) to resolve the abovementioned problems. This fastener can connect electronic components on a substrate at room temperature using the van der Waals force between each nanowire. In this paper, we introduce a preparing method of a high-density nanowire array constituting the NSF. The NSF fabricated through the simple template method showed the room temperature bonding ability. The NSF’s adhesion strength and electrical properties were investigated by adjusting the nanowire parameters, such as diameter, length, density (number per area), preload, and shape. We also introduce some NSF applications, such as 64-pin NSF that behaves like a ball grid array for application to actual electronic devices and the fabrication of an NSF on a flexible substrate.</p>
