Description

Technical Field

[0002] With the development trend of notebooks, tablet computers, mobile phones and other consumer electronic products becoming smaller and thinner, the design and manufacturing process requirements for their components are becoming higher and higher. As the products become thinner and lighter, the internal space becomes very narrow, which requires that the internal layout of the product must be densely packed, and the volume of each electronic component is getting smaller and smaller, thinner and lighter, and the reliability requirements for the process technology and product connection are getting higher and higher. Take the Wifi antenna as an example. The antenna is a receiving device used by digital products such as notebooks and mobile phones to receive wireless signals. It plays a vital role in the transmission quality of wireless signals. The existing antennas are generally connected to a connecting device. Since the antenna itself is a wire material, it is relatively soft, making it difficult to fix, which brings great inconvenience to the automated assembly, resulting in low production efficiency and high cost.
