In electronic manufacturing, anomaly detection of surface mount devices (SMDs) through
computer vision (CV) is an important task to control the production quality of SMDs. The …

Cracking remains the major reason of failures in multilayer ceramic capacitors (MLCCs)
used in in space electronics. Due to a tight quality control of space-grade components, the …

Multilayer ceramic capacitors are prone to mechanical defects and damage because of the
fragility of the ceramic dielectric. Because these faults are often not recognized by visual or …

Industry-produced printed circuit boards (PCBs) used by the US Department of Defense are
typically coated with a layer of “conformal coating” made of silicone or polyurethane in order …

Solder joint voids are usually formed by the entrapped gas bubbles during the reflow
process and are common in all surface mount applications. It is a controversial issue on the …

Measurements of resonant ultrasonic frequencies of multilayer ceramic capacitors (MLCCs)
were performed as a function of excitation amplitude to assess the potential of nonlinear …

Laser-generated ultrasound represents an interesting nondestructive testing technique that
is being investigated in the last years as performative alternative to classical ultrasonic …

A laser ultrasound and interferometer inspection system has been successfully applied to
detect solder bump defects, including missing, misaligned, open, and cracked solder bumps …

The effect of compressive mechanical stresses on chip solid tantalum capacitors is
investigated by monitoring the characteristics of different part types under axial and …

Resonant ultrasound spectroscopy (RUS) was used in this paper to measure shifts in
resonant frequency that arise from the presence of cracks in barium-titanate-based …
