Abstract
An apparatus for providing mechanical support to a column grid array package is disclosed. The column grid array package uses solder columns to provide electrical connections between a ceramic substrate and a printed circuit board. The ceramic substrate has two sides, with an integrated circuit chip mounted on one side and many input/output pads mounted on the other side. Solder columns are attached between the input/output pads and the printed circuit board. A corner post is located at each corner of the column grid array package to secure the position of the ceramic substrate in relation to the printed circuit board.
