摘要： A strain gauge includes: a flexible substrate; a resistor formed on one side of the substrate; a pair of terminal parts electrically connected to both ends of the resistor; and a plurality of resistance value tuning wires configured to tune the resistance value between the pair of terminal parts. In this strain gauge, the plan shape of the resistor is a spiral shape formed by two linear resistance wires about the halfway part of the two linear resistance wires, the two linear resistance wires being a predetermined space apart from each other and extending in the same direction from the halfway part, and the resistance value tuning wires are arranged discretely so as to bridge between the two linear resistance wires.

摘要： 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.
