This case study explores the changing climate for manufacturing in Mexico as volumes and demand increase in the region and manufacturers, including IMI, look to grow through greater automation and closer collaboration with key technology partners like Koh Young. With interviews with Oscar Valdivia, IMI's Manufacturing Unit Manager for Guadalajara, and Philip Reyes, their Regional Engineering Head, the case study digs into how manufacturing excellence can be developed with the right use of automation and by investing in equipment that creates efficiency and quality through better use of accurate data.

Ceramics packages are being used in the electronics industry to operate the devices in harsh environments. In this paper we report a study on acoustic imaging technology for nondestructively inspecting underfill layers connecting organic interposers sandwiched between two ceramics substrates.First, we inspected the samples with transmission mode of scanning acoustic tomography (SAT) system, an inspection routine usually employed in assembly lines because of its simpler interpretation criteria: flawed region blocks the acoustic wave and appears darker. In this multilayer sample, this approach does not offer the crucial information at which layer of underfill has flaws. To resolve this issue, we use C-Mode Scanning in reflection mode to image layer by layer utilizing ultrasound frequencies from 15MHz to 120MHz. Although the sample is thick and contains at least 5 internal material interfaces, we are able to identify defective underfill layer interfaces.
