Degradation of silicone-based sealing materials used in microelectronics

Adhesive bonding is a key joining technology in many industrial applications, including automotive, aerospace industries, biomedical devices, and microelectronic components. Adhesive bonding is gaining more and more attention due to the increasing demand for joining similar or dissimilar components, mostly within the framework of designing...

Degradation of bisphenol-a-polycarbonate (BPA-PC) optical lenses under simulated harsh environment conditions

This paper investigates degradation and failure mechanisms of BPA-PC lenses in simulated harsh environment conditions. Exposure of secondary optics in Light Emitting Diode LED-based systems or any other similar applications to environmental stresses can adversely effect the performance and lifetime of products. This paper simulates a harsh...

Reliability of LED-based Products is a Matter of Balancing Temperatures

Solid State Lighting (SSL) technologies and products are gradually pervading into our daily life. An SSL system is composed of a LED engine with a micro-electronics driver(s), integrated in a housing that also provides the optical, sensing and other functions. Knowledge of (system) reliability is crucial for not only the business success of the...
