China Electronics Fair is the longest-running electronics exhibition in the country, first staged in 1964 and organised around basic electronic components. That focus sets the layout: components, integrated-circuit applications, computing infrastructure and special-purpose electronics sit in separate halls, with the supply chain between them filling the floor.

The fair serves the application industries that consume those components — 5G, new energy, the internet of things, big data and cloud computing, lighting and display, security, consumer electronics, intelligent manufacturing and energy electronics. A defence and aerospace procurement strand runs through it as well, with sourcing and R&D departments from the aviation, space, shipbuilding, ordnance and electronic equipment sectors taking part.
