Spring in March, spring flowers. From March 19 to 20, the management and technical elites of PCB industry gathered in Shanghai to participate in the "2019 Spring International PCB technology / Information Forum" sponsored by China Electronic Circuit Industry Association and organized by CPCA science and Technology Committee. Over the years, the forum has provided a platform for enterprises to exchange and learn from each other, making the whole industry form a strong atmosphere of learning and research.

PCB provides interconnection and signal transmission between electronic products. Technological progress promotes the development of smart phones and other 3C electronic devices in the direction of thinness, miniaturization and action. In order to achieve the goal of less space, faster speed and higher performance, the requirements of "light, thin, short and small" for PCB are constantly improved. PCB provides electronic interconnection, downstream demand drives PCB growth, PCB provides interconnection and signal transmission between electronic products. It not only provides electrical connection for electronic components, but also carries digital and analog signal transmission, power supply and RF micro devices
