Abstract
A ball grid array (BGA) package test module includes BGA packages, a module board, and test architecture for use in testing the BGA packages while they are mounted to the module board. The test architecture of the BGA package test module includes package test signal lines connected to solder balls of the BGA packages as extending along a bottom surface of the BGA packages, board test signal lines extending along the module board, and electrical junctions that interconnect the package and board test signal lines. Signals from the BGA packages can be picked up by the probe of a testing apparatus via the board test signal lines. The present invention is advantageous in that it minimizes the effect of stubbing by the test signal lines when the memory module is operating.
