Zusammenfassung:Aspects include a hybrid socket dynamic warp indicator for socket connector systems and methods of using the same to measure the warpage of a printed circuit board assembly. The method can include providing a printed circuit board having a plurality of pads and a socket. A warp indicator having a plurality of solder joint connections and a resistor array is electrically coupled to the printed circuit board to build a printed circuit board assembly. The printed circuit board assembly is subjected to a thermal event. A resistance across the resistor array is measured after the thermal event. A number of separations between one or more pads of the printed circuit board and one or more solder joint connections of the warp indicator is determined based on a change in the resistance. A defective warpage condition for the socket is determined based on the number of separations.
