Abstract
A method of bonding components is disclosed. One embodiment of such a method includes applying both heat and pressure to a stack of components that includes an interposer with a reduced degree of warpage. Reducing the distance between the interposer and a first component of the stack of the components until a spacer prevents further reduction of that space. Then, cooling the stack of components while the pressure is maintained such that the degree of warpage of the interposer remains reduced.
