Solder Joint Reliability in Solid-State Lighting Applications,. The interest in solder joint reliability has increased by the introduction of the so-called high brightness leadless type of packages. Solder joint reliability is one of the main failure modes in these package types, especially when it comes down to lifetimes beyond 20,000 h. Many end customers re

A Multiscale Approach for Interfacial Delamination in Solid-State Lighting, LED packages suffer from delamination as well, mainly due to the fact that transparent materials are needed to pass the light from the device to the surroundings. Using these kinds of materials has a significant impact on the mismatch of material properties. Any gap in the optical pathway will crea

,On the Effect of Microscopic Surface Roughness on Macroscopic Polymer–Metal Adhesion,crease in surface area, is the transition from adhesive to cohesive failure, i.e., crack kinking. This chapter presents several analysis methods to study this phenomenon. First, a semi-analytical approach is discussed in which the competition between adhesive and cohesive cracking is analyzed by mea
