<p>A method of fabricating circuit packages which employ macro-components (10) mounted on supporting substrates (20). In order to maintain sufficient clearance between the component and substrate and achieve high reliability bonds, massive solder spheres (16) are applied to contact pads (14) on either the component or substrate. After contact pads of both carrier and substrate are brought into contact with the spheres, the bond is formed by reflowing the solder while maintaining a component to substrate clearance of at least 0.25mm due to surface tension of the solder spheres. </p> |
