Probabilistic Design for Reliability in Electronics and Photonics July 19, 2017 11:00 AM EDT  Register 

Presenter: Ephraim Suhir


The recently suggested probabilistic design for reliability (PDfR) concept in electronics and photonics (EP)  is based on  1) highly focused and highly cost-effective failure oriented accelerated testing (FOAT),  aimed at understanding the physics of the anticipated failures and at quantifying, on the probabilistic basis, the outcome of  FOAT conducted for the most vulnerable element(s) of the product of interest for its most likely applications and the most meaningful combination of possible stressors (stimuli); 2) simple and physically meaningful predictive modeling (PM), both analytical and computer-aided, aimed at bridging the gap between the FOAT data and the most likely  operation conditions; and 3) subsequent FOAT-and-PM-based sensitivity analyses (SA) using the methodologies and algorithms developed as by-products at the two previous steps.  The PDfR concept proceeds from the recognition that nothing is perfect and that the difference between a highly reliable and an insufficiently reliable product is “merely” in the level of the probability of its failure. If this probability, evaluated for the anticipated loading conditions and the given time in operation, is not acceptable, SA can be effectively employed to determine what could/should be changed to improve the situation. The PDfR analysis enables one also to check if the product is not over-engineered, i.e., is not superfluously robust.  If it is, it might be too costly. The operational reliability cannot be low, but it does not have to be higher than necessary either. It has to be adequate for the given product and application. When reliability and cost-effectiveness are imperative, ability to optimize reliability is a must, and no optimization is possible if reliability is not quantified. It is shown also that the optimization of the total cost associated with creating a product with an adequate (high enough) reliability and acceptable (low enough) cost can be interpreted in terms of the adequate level of the availability criterion. The major PDfR concepts are illustrated by practical examples. We elaborate on the roles and interaction of analytical (mathematical) and computer-aided (simulation) modeling. It is shown also how the recently suggested powerful and flexible Boltzmann-Arrhenius-Zhurkov (BAZ) model and particularly its multi-parametric extension could be successfully employed to predict, quantify and assure operational reliability. The model can be effectively used to analyze and design EP products with the predicted, quantified, assured, and, if appropriate and cost-effective, even maintained and specified probability of operational failure. It is concluded that these concepts and methodologies can be accepted as an effective means for the evaluation of the operational reliability of EP materials and products, and that the next generation of qualification testing (QT) specifications and practices for such products could be viewed and conducted as a quasi-FOAT that adequately replicates the initial non-destructive segment of the previously conducted comprehensive full-scale FOAT.

Pb-free solder is now ubiquitous throughout the packaging industry. Pb-freesolder interconnects dominate the high-end packaging interconnects: from large ball grid array (BGA) used on organic laminate to board connections, to flip chip joints on laminates, to micro-pillar forchipto Si on 2.5D or 3D interconnects   But, how robust are these connections? Which defects are common and which can be avoided?  This talk will cover one of the more common interconnect defects: solder voids.  It will explain the root cause of solder voids occurring during structure fabrication, assembly and reliability stress, as well as detection methods and possible actions to prevent them.
