MicroBGA - Computer Definition
A CSP BGA chip package from Tessera Inc., San Jose, CA (www.tessera.com). The ÂµBGA architecture uses very fine pitch between the solder balls that enable the packaging to be barely larger than the chip itself. Tessera's unique design uses elastomer layers to withstand changes in temperature between the printed circuit board and the chip (CTE). See CSP, BGA and CTE.
