context_page_description: A ball grid array is a type of surface-mount packaging 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 traces connecting the package's leads to the wires or balls which connect the die to package 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.

  CBGA and PBGA denote the Ceramic or Plastic substrate material to which the array is attached.
  CTBGA: Thin Chip Array Ball Grid Array
  CVBGA: Very Thin Chip Array Ball Grid Array
  DSBGA: Die-Size Ball Grid Array
  FBGA:  Fine Ball Grid Array based on ball grid array technology. It has thinner contacts and is mainly used in system-on-a-chip designs; 
  also known as Fine Pitch Ball Grid Array (JEDEC-Standard) or 
  Fine Line BGA by Altera. Not to be confused with Fortified BGA.

  To make it easier to use ball grid array devices, most BGA packages only have balls in the outer rings of the package,
  leaving the innermost square empty.
  Intel used a package designated BGA1 for their Pentium II and early Celeron mobile processors.  BGA2 is Intel's package for their Pentium III and some later Celeron mobile processors. BGA2 is also known as FCBGA-479. It replaced its predecessor, BGA1.
  For example, the "Micro-FCBGA" (Flip Chip Ball Grid Array) is Intel's current BGA mounting method for mobile processors that use a flip chip binding technology. It was introduced with the Coppermine Mobile Celeron. Micro-FCBGA has 479 balls that are 0.78 mm in diameter. The processor is affixed to the motherboard by soldering the balls to the motherboard. This is thinner than a pin grid array socket arrangement, but is not removable.
  The 479 balls of the Micro-FCBGA Package (a package almost identical to the 478-pin Socketable Micro-FCPGA Package) are arranged as the 6 outer rings of a 1.27 mm pitch (20 balls per inch pitch) 26x26 square grid, with the inner 14x14 region empty.
