What is Minimum Clearance BGA PCB?

Minimum Clearance BGA (Réseau de billes) PCB refers to a type of printed circuit board design that requires the smallest possible spacing between the solder balls or pads of a BGA component. In BGA packages, the connection between the chip and the PCB is made through an array of solder balls, which are arranged in a grid pattern. The minimum clearance, also known as the minimum pitch, is the smallest distance between the center of one solder ball to the center of the adjacent ball. This parameter is crucial in high-density PCB designs where space is limited, as it directly impacts the routing complexity and the ability to fit more components on a single board.

In Minimum Clearance BGA PCBs, achieving a small pitch is essential for several reasons. It allows for a higher density of connections, enabling more functionality in a compact area.
