Abstract:
A socket assembly comprising:a printed circuit board; an insulative base mounted on the printed circuit board with a plurality of contacts each with a solder ball at a bottom end thereof, said base defining a mounting portion on a bottom periphery thereof, said mounting portion defining a first surface around a middle portion thereof and a second surface around a side region thereof; wherein between the first surface and the second surface is defined a vertical offset for reducing a space formed between the first surface and a mother board due to warpping under thermal stress of the mounting portion; wherein before soldering, the first surface is closer to the printed circuit board than the second surface; after soldering, the first surface is deformed away from said printed circuit board while the second surface is deformed toward said printed circuit board wherein before soldering the first surface is seated upon the printed circuit board while after soldering the second surface is seated upon the printed circuit board.
