Patent ID: 7007835

Claim:
A method of bonding an element to a substrate, the method comprising the steps of: a) providing a substrate having a generally flat surface, b) placing two or more solder bumps having a predetermined volume on either the substrate or on the element, the bumps defining a single axis, c) determining a shape, size and location of two or more solder pads on the other of the substrate or element so as effect a predetermined orientation of the element at a predetermined angle with respect to the substrate during heating and melting of the solder bumps, d) effecting a contact of the element with the substrate via the solder bumps, such that the element is supported on the solder bumps only in a first supported position, and e) after step (d) heating the solder bumps in the absence of any further supporting or orienting of the element to cause a flow of the solder bumps and to cause a predetermined tilting displacement of the element by gravity forces and by surface tension forces substantially about the axis defined by the solder bumps so as to re-orient the element at a predetermined angle in a second secured position between angles greater than 0 and less than 90 degrees with respect to the substrate by said heating alone.
