... solder joint/bump defects, including missing, misaligned, open, and cracked solder joints/bumps in flip chips, chip scale packages, and multilayer ceramic capacitors. This system uses a pulsed Nd:YAG laser to induce ultrasound in the electronic packages in the thermoelastic regime; it then measures...

... cell finite element (FE) analyses of PCB’s with both straight and wavy traces were performed to predict thermoelastic behavior. Both experimental tests and numerical analyses conclude that the PCB’s with wavy traces warped approximately 40% to 60% less than the PCB’s with straight traces...

... . In these investigations, the stresses at the joint interfaces are required for deriving the bending moment and the forces in each layer. Daniel et al. 14 analyzed the state of residual stresses and warpage in multilayer structures using linear thermoelastic lamination theory. Pan and Pao 15 analyzed the deformation...
