Abstract
An integrated circuit package is provided with alignment pads which are solid or annular ring shaped. Alignment members such as balls or bullets are attached to the alignment pads via a wetting media. When heated, the wetting media serves to center and seat the alignment members on the alignment pads. When cooled, the wetting media serves to bond the alignment members to the alignment pads.
