Ball grid array

From Wikipedia, the free encyclopedia

A grid array of solder balls under an integrated circuit chip, with the chip removed; the balls were left attached to the printed circuit board.

ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter. The leads are also on average shorter than with a perimeter-only type, leading to better performance at high speeds.

Soldering of BGA devices requires precise control and is usually done by automated processes. BGA devices are not suitable for socket mounting.
