This paper "Long Term Investigation of Urethane Conformal Coating Against Tin Whisker Growth" was presented by Lyudmyla Panashchenko of NASA GSFC at the IPC Tin Whisker Conference, in December 2010. It describes the results of 11 years of aging of a conformal coat and its ability to inhibit tin whisker growth. It shows that whiskers continue to grow with time and how they may be constrained by the...

"Final Finish for Connectivity" was presented by George Milad of Uyemura International Corporation at the IPC Conference for the PCB Industry: Critical Issues for the Military Market, in December 2011. The author describes surface finishes applied to printed circuit boards to enhance their reliability, solderability, shelf life and the applicability to wire bonding. He also mentions the IPC...

This presentation "Trends in Military Certifications: What You Need to Know About the Obvious and the Obscure," was presented at the IPC Conference for the North American EMS Industry, What it Takes to Supply the Military, Management Session, in September 2010 by Steve DeWaters, president of Penumbra Strategies, Inc. It describes the rise of Commercial Off the Shelf (COTS) items and why Military...

There are a large number of new lead-free alloys that address the manufacturing problems inherent in current lead-free products on the market. However, their reliability properties are less understood than many of the first alloys introduced, for example SAC 305. While it is tempting to look to the new alloys as solutions to manufacturing issues of the older materials, the lack of reliability...

The IPC Solder Products Value Council’s Technical Subcommittee Report “Take Action Limits (TAL) for SAC305 Lead Free Soldering Processes Utilizing Solder Baths/Pots” reports on research on take action limits of solder pot contamination for SAC305 lead-free solder. As opposed to one maximum contamination level, the IPC SPVC opted to identify three action levels: Normal operation defined as the...

IPC-WP-023 is an IPC Technology Solutions White Paper addressing reliability issues associated with stacked microvias. There is evidence that staggering vias can result in a more robust structure; however, staggering microvias is only a temporary solution to accommodate complex designs with microvias built with weak interface structures IPC-WP-023 white paper provides an investigation of these...

Presenta también un resumen de la historia de la prueba de ROSE junto con explicaciones sobre las limitaciones de esta prueba.

Pb-free materials are considered a major technology disruption to traditional Pb-based interconnect materials for electronics, which is of particular concern for the aerospace, defense, and high performance products (ADHP) industries where safety cannot be compromised and applicable reliability data remains scarce. Until validated data and modelling methods are developed, projects considering Pb...

Ion chromatography has been recognized as a method for which the data output is ion specific and very precise in the quantification of ionic residues. This paper is intended for those contemplating the setup of an ion chromatography lab and provides many of the practical considerations that should be addressed, including the core components of an ion chromatograph system such as carrier solutions...
