BGA, uBGA and FP BGA | 24 February, 1999

Are the terms "uBGA" and "Fine Pitch BGA" synonomous, different all-together, or is Fine Pitch BGA a subset of uBGA? Thanks.

�BGA�: Micro BGA�. A brand name for a fine pitch BGA from Tessera. Fine Pitch (1) In SMD: Surface mounted components with a lead or termination pitch of 0.025 (some say 0.020) inch or less. (2) In BGA: With standard pitch is 1.27 (some say 1.0) mm, anything less requires special handling. (3) The pitch that is difficult to place (requires a cost adder) in manufacturing (assembly) practice.
