Patent ID: 7371673

Claim:
A method comprising: applying solder paste onto at least one of a plurality of contact pads on a PCB; placing at least one of a plurality of solder balls attached to a substrate of an IC device onto the at least one of the plurality of contact pads on the PCB; elevating the temperature to reflow the solder paste; using a lifting mechanism to pull the IC device away from the PCB as a function of a geometric shape of the IC device and holding the IC device in a new position upon reflowing the solder paste to transform the at least one of the plurality of solder balls and the reflowed solder paste into a high shear strength solder joint structure; and lowering the reflow temperature to room temperature, thereby attaching the high shear strength solder joint structure to the at least one of the plurality of lands on the PCB and the substrate of the IC device.
