Monitoring Fatigue Cracking in Interconnects in a Ball Grid Array by Measuring Electrical Resistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In displacement controlled mechanical fatigue of ball grid solder interconnect arrays, decrease in maximum load monitors total increase in crack area in an array while electrical resistance ...
A Digital Algorithm for Near-Minimum-Time Control of Robot Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A digital state feedback control algorithm has been developed to obtain the near-minimum-time trajectory for the end-effector of a robot manipulator. In this algorithm, the poles of the linearized ...
