On Oreology, the fracture and flow of "milk's favorite cookie® "

The mechanical experience of consumption (ie, feel, softness, and texture) of many foods is intrinsic to their enjoyable consumption, one example being the habit of twisting a sandwich cookie to reveal the cream. Scientifically, sandwich cookies present a paradigmatic model of parallel plate rheometry in which a fluid sample, the cream, is held between ...

Reliability and Failure Mechanisms of Laminate Substrates in a Pb-free World

This presentation surveys the most significant via and via-related laminate failure mechanisms from past to present using data from current induced thermal cycling (CITC) testing, failure analysis, and other sources. The relative life and failure modes of thru vias, buried vias, and microvias (stacked vs. non-stacked) are compared, along with the affect of ...

Instrumentation for Studying Real-time Popcorn Effect in Surface Mount Packages during Solder Reflow

Occurrence of popcorn in IC packages while assembling them onto the PCB is a well known moisture sensitive reliability issues, especially for surface mount packages. Commonly reflow soldering simulation process is conducted to assess the impact of assembling IC package onto PCB. A strain gauge-based instrumentation is developed to investigate the popcorn effect in ...

Understanding and optimizing delamination/recycling of printed circuit boards using a supercritical carbon dioxide process

A printed circuit board (PCB) is an integral component of any electronic product and is among the most challenging components to recycle. While PCB manufacturing processes undergo generations of innovation and advancement with 21st century technologies, the recycling of PCBs primarily employs 1920's shredding and separation technologies. There is a critical need ...

Common failure mechanisms in conformal coating: Delamination

In conformal coating, there are several mechanisms that cause failure of printed circuit boards (PCBs). In a series of technical bulletins SCH will examine the common failure mechanisms in conformal coating including capillary flow, delamination, cracking, loss of adhesion, dewetting, corrosion, orange peel, pinholes, bubbles and foam.

Bad solder under SMD electrolytic caps -- Hello ! I've noticed some hardening and partial non-melting in one project, under SMD electrolytic caps. All other components and solder joints are fine on this board. I use Interflux LMPA solder paste (low melting point). I have a theory. The caps are located in board area, which has no planes on top/bottom layers. And the pads are small and mostly hidden under the cap. Could it be that the cap is shielding the heat and there is not enough to melt all the joint ? Also, maybe the lack of heat disturbs the flux flow ? I think I have to make pads bigger so there will be more heat coming in.. Has anybody seen similar behaviour / problems ?
