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.

I go through this every time I have PCBs I need to populate with SMD parts, and this has become more an issue as pin spacings have gotten tighter, and my hands have become less steady with age. How do you hold SMD part in place while soldering?
While bored recently, I decided to take apart a few old pieces of electronic equipment and attempt to reverse-engineer them. I’ve been doing pretty well, but I’ve come to an IC that I can identify but doesn’t seem to exist on the manufacturer’s website.
When I audit a supplier, I find that they label PCB bare part. Why do they do that and what is the advantages?
