Second generation package.  Still thru-hole, but the package size is reduced by moving pins to the underside of the packages in a grid pattern.  The pins are located on a 0.1" grid in various patterns.  The grids is called out by the pins in the x direction and the pins in the y direction.

Package Variations
Interstitial package(IPGA): type carries additional pins on a 0.5" offset pattern in between the pins of a regular PGA pattern. It almost doubles the available pins on the same package size as a standard PGA.
