Counterfeit Electronic Components: Understanding the Risk

Mar 08, 2012 | John M. Radman, Renee J. Michalkiewicz and Daniel D. Phillips

You may have heard talk in the news lately regarding counterfeit electronic components making it into the US military supply chain. The U.S. Senate Armed Services Committee (SASC) recently reported in the Counterfeit Electronic Parts in the Defense Department Supply Chain hearing held on November 17, 2011, 1,800 cases of suspected counterfeit components that went into more than 1 million individual products. If you consider this number for the military, we can only imagine the number of counterfeits in our commercial yet high reliability products, such as life support or other critical systems. If you are the person within your electronics-based company who must perform risk analyses, counterfeiting is not a new concern, yet many do not realize just how good counterfeiters have become at their "trade"....

Modelling of Thermal Stresses in Printed Circuit Boards

Oct 20, 2011 | Oldŕich Šuba, Libuše Sýkorová, Štépán Šanda, Michal Stanék

Results of FEM modelling of thermal stress analysis in printed circuit boards are given in the article. It is shown that thermal stress alone is not solely caused by differences in coefficients of thermal expansion of individual layers. The emergence of thermal stress is subject to both the layered structure of the wall and given boundary conditions, as well as the existence of a temperature gradient in the direction normal to the surface of the wall. A practical application focuses on the issue of recycling of PCB with the effort to achieve separation of layers due to thermal stress. Role modelling of thermal stress in this area lies in predicting the possibility of separation, depending on the type of thermal stress and material parameters....

Are Separate Solder Flip-Chip Bonders Still Required?

Oct 13, 2011 | Eric Klaver, Senior Product Manager, Assembléon. Patrick Huberts, Product Manager Semicon Market.

Increasing miniaturization is now encouraging manufacturers of handheld devices to stack bare dies or packages. As the process of manufacturing modules requires placing both passives and (stacked) bare dies, these two types of placement are merging very quickly into a single platform. That raises the question of whether SMT equipment will take over from traditional die bonders....

Development of a Design & Manufacturing Environment for Reliable and Cost- Effective PCB Embedding Technology

Oct 06, 2011 | M. Brizoux, A. Grivon, W. C. Maia Filho; Thales Corporate Services. J. Stahr, M. Morianz; AT&S. Hemant Shah, Ed Hickey; Cadence Design Systems Inc.

The desire to have more functionality into increasingly smaller size end products has been pushing the PCB and IC Packaging industry towards High Density Interconnect (HDI) and 3D Packaging (stacked dies, embedded packaged components). Many companies in the high-end consumer electronics market place have been embedding passive chip components on inner PCB and IC Packages for a few years now. However, embedding packaged components on inner layers has remained elusive for the broader market due to lack of proper design tools and high cost of embedding components on inner layers (...)

Accurate information that provides a business owner or manager the ability to make immediate decisions about his/her operation resulting in a boost to profitability is crucial during an economic downturn.
