QSOP Quarter-Size Small Outline Package. An SO style IC package that has leads on a 25 mil pitch. The name derives from the fact that the package is approximately ½ the length and ½ the width of a standard SOIC, and thus a package of the same pin count occupies approximately ¼ the area on a PWB.

TBGA Tape Ball Grid Array. A ball grid array component package that uses TAB techniques to make the connections between the IC chip and the solder balls. This results in a solder ball grid array that is only around the periphery, and leaves compliant connections between the IC and the solder balls for better TCE reliability.
