BGA stands for Ball Grid Array. It is a style of component footprint. These footprints appear as a rectangular array of small circles – one where each “ball” of the component is attached.
There will generally be a rectangular outline around the array that corresponds to the edges of the component’s package, and probably also some silkscreen (written) information identifying the component.
