A novel reliability test methodology is proposed, which applies fiber Bragg grating (FBG) strain sensors to detect flexure-induced pad cratering fractures in advanced microprocessor assemblies. Failure detection and reliability evaluation for such small-scale structures are of common interest and key concerns for both manufacturers and users. The application demonstrates that by combining the features of small geometric size, light weight, high sensitivity, and immunity to environmental instability, the FBG-based micromeasurement technology provides a unique nondestructive ...
