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.

Ouça sobre o serviço de montagem de PCB BGA, mas eu nunca ordeno. Como podemos identificar a área BGA do PCB? Apenas muito curioso.
Máquina de lavar não funciona. Desde que comprei há um ano, os componentes nele não são antigos, Eu penso. Então, eu quero verificar em seu PCB. Any tips on this?
There is a copper pour over the entire top of the my PCB, which is part of GND net. It turns out that the surface mounted 1W LEDs I’m going to use have the heat slug connected internally to the LED’s +ve terminal. Can I rely on the solder mask to insulate the +ve voltage (~3V ish) from GND? Long term?
