BGA
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A Ball Grid Array (BGA) is a type of surface-mount package that uses an array of solder balls on the underside of the component to connect to the PCB.
Example in context
“The design uses a 0.5 mm pitch BGA component, requiring careful routing and via placement.”
“Tasarım, dikkatli yönlendirme ve via yerleşimi gerektiren 0.5 mm aralıklı bir BGA bileşeni kullanır.”
Where engineers use it
BGA packages are common for high-density designs; engineers must ensure adequate pad coverage, via-in-pad capability, and sufficient thermal relief for reliable soldering.
Synonyms: ball grid array
Practice: can you use “BGA” at work?
You are designing a PCB for a high-speed FPGA. The FPGA is a BGA with 0.8 mm pitch. Discuss the challenges of routing, via size, and thermal management for this component.
