electronica Shanghai is the Shanghai edition of the electronica circuit, built as an application-led electronics fair rather than a components catalogue. Exhibitors are grouped by the industries their parts end up in (new energy and intelligent vehicles, green energy, smart factories, the industrial internet, wireless communication, data centres, wearables and smart home), and are expected to show how a device is designed in and put into production.

Its scope runs the whole length of the supply chain: semiconductors, power devices, sensors and MEMS, passive components, relays and connectors, printed circuit boards and other circuit carriers, embedded systems and micro-nano systems, power supplies and test and measurement, plus electronics manufacturing services and the AI and robotics work that now sits on top of them.
