Everyone is aware that getting their products produced in China should reduce costs. However, this article, addresses the fact that the support engineering activity is lacking. The military infrastructure in the US must maintain a level of critical resources for their products. Can this be applied to bring jobs back to the US in other sectors by maintaining a high level of expertise and infrastructure? Andy Grove talks about how Intel accomplished just that. Let DfR help you to define reliable manufacturing operations that reduce costs. For more information contact Cheryl Tulkoff.

Causes of Tin Whiskers: Theories of Formation
Craig Hillman, Ph.D., CEO, DfR Solutions
This workshop will help provide an understanding of fundamental drivers for tin whiskers: how they can be related to presence/absence and growth rates under a variety of environmental conditions. Discussions will focus on current theories on tin whisker initiation and growth: a review of material diffusion, stress gradients, oxide formation and how various plating elements and environments play a critical role in these behaviors.
General trends in research from exposing tin plating to a variety of environments (temperature, humidity, vibration, mechanical shock, corrosion, pressure, bending) will be reviewed and related back to drivers. The ability to test for and predict the occurrence of tin whiskers will be presented, with a critical review of existing tin whisker prediction algorithms and the risk/benefit of implementing these equations into design decisions and reliability predictions.
Craig Hillman, Ph.D. is CEO and managing partner of DfR Solutions. Dr. Hillman's expertise includes best practices in design for reliability (DfR), lead-free strategies, supplier qualification for commodity and engineered products, passive component technology, and printed board failure mechanisms. Dr. Hillman holds two patents, has published more than 50 white papers, and has appeared in more than 40 publications; he has presented on a wide variety of reliability issues to over 250 organizations.

Engineering Design Practices.
Review of past recalls suggests that manufacturers of external defibrillators sometimes use design practices that lead to inconsistent device performance. In one example, a firm designed its voltage-monitoring circuit to draw power from the same power source it was intended to monitor. Because of this design, a momentary drop in the voltage caused a false signal to shut down the AED and the device was unable to deliver a shock, which may have caused a patient’s death. In another case, a firm used the wrong kind of component in one of the circuits, causing the device to be susceptible to interference from noise coming from the device’s power line. Good engineering design practices also require user interfaces (like dials, monitors, alarms, and connectors) meet users’ needs. Recent surveys suggest that improvements in user interfaces may be warranted.
The FDA’s analysis of recalls and inspections identified problems in how manufacturers test and incorporate components used in the manufacture of external defibrillators, as well as how they evaluate changes to the device before they are implemented to assure that device modifications do not adversely impact the safety and effectiveness of the technology. Between 2005 and 2010, the FDA issued nine warning letters to external defibrillator manufacturers, seven of which cited the firms for failing to appropriately control these aspects of their manufacturing process.
In several cases, manufacturers purchased components from suppliers who did not meet the manufacturers’ required specifications. In some cases, the problem with the component was due to a change in how the component was manufactured by the supplier. However, it is the manufacturer’s responsibility to assure that the components it receives meet its specifications.
Design and Manufacturing are two key areas where DfR can help your company prevent problems! For more information, please contact Cheryl Tulkoff, email@example.com.

0201 and 01005 components have grown to represent a large portion of the modern component market and usage will continue to increase as time goes on. Currently, issues with manufacturability, cost of use, and inspection limit wider adoption of these components. The trend for smaller products in certain industries will drive an increase in adoption that will necessarily result in improved practices in manufacturing. As the market matures, and more reliability data becomes available, even those applications where reliability is paramount will begin to see adoption of these small parts. Indeed, the majority of respondents to DfR Solutions’ survey expect to be using 0201 components within the next three years.

Increased circuit board densities coupled with the need for higher electrical performance have resulted in a new reliability challenge, that of vias in close proximity to either SMT or BGA pads. In an effort to reduce inductance, increase density or employ finer pitch array packages, via pads are being placed close to the SMT/BGA lands. Thicker PWBs, due to higher I/O array packages exacerbate these issues as larger holes and pads may be required to maintain through-hole reliability. DfR has extensive experience in both modeling the filled via concept and analyzing failures associated with this defect. For more information contact, Nathan Blattau, email@example.com.
