A Short Course in Failure Analysis of Electronics

When- Tuesday September 17 – Friday September 20, 2013
Venue: University of Maryland College Park, MD 20742
Electronic Supply Chain Solutions sponsors Quality Lessons Learned and provides this important  information about this program its registration, and contact info.


 Organizations involved in activities within the electronics supply chain are facing new challenges—not just from complex components and assemblies, harsher lifecycle environments, and newer materials, but also from a need for quicker turn-around. Engineers need a clear understanding of the failure mechanisms of electronic products as well as familiarity with the tools and techniques used to determine the root causes of failures.
 
Twice every year, CALCE and Buehler jointly offer a four-day course on failure analysis of electronics at the University of Maryland, College Park campus. Over 120 engineers from leading companies and government organizations from around the world, ranging from NASA to Microsoft, have taken this course. With a combination of classroom instruction, case studies, demonstrations, and hands-on laboratory training, this course covers topics ranging from failure mechanisms in electronics to specimen preparation, physics of failure, reliability, root cause analysis methodology, and materials analysis techniques.


Engaging and knowledgeable lecturers from CALCE and Buehler provide practical recommendations with numerous failure analysis case studies. The case studies illustrate the use of an array of failure analysis techniques to arrive at the root causes of field failures on printed circuit boards, passive and active components, and assemblies. Attendees will get a comprehensive picture of the variety of approaches and methods used and the rationale behind the selection of these techniques to uncover the root cause in the four cases. Each case study is concluded with recommendations for corrective actions that assist in minimizing downtime as well as prevent future occurrences of the problem.


The next course is being offered on September 17-20, 2013. Act quickly—seating is limited, so register today. Please use the attached form for registration. The course fee is $2500. A 20% discount for CALCE consortium members and federal government employees applies (final cost for CALCE consortium members and federal government employees is $2000).


Upon successful completion of this course, attendees will be awarded 1.6 Continuing Education Units (CEUs) from the University of Maryland. CEUs are an important credential for many in today’s competitive workplace.
Each attendee, once registered, is invited to submit one sample to CALCE at least three weeks before the course starts. Several of the submitted samples will be prepared and analyzed in advance for use during course demonstrations. Some of the other samples will also be used for hands-on training sessions during the course to illustrate specimen preparation procedures and analysis techniques. All unused samples will be returned. However, no guarantee can be offered that any specific sample will be used during the course.

Counterfeit Electronics - Risks and Mitigation

Another Quality Lessons Learned

Two Part Webtorial, August 14 and 21, 2012
 1:00 - 2:30 pm EDT

Overview

Center for Advanced Life Cycle Engineering (CALCE) provides efficient and cost-effective failure analysis services, counterfeit parts inspection, design reviews, reliability audits, and warranty cost analysis assessment assistance for all interested parties. In the parts procurement process, the purchase of an electronic part from a part manufacturer or its authorized supplier presents very low risk. However, parts are often purchased from unauthorized sources such as independent distributors and part brokers for a variety of reasons, including part obsolescence, lead time, or unavailability of parts from authorized sources. There is a need for authentication and screening of the parts purchased from such sources to verify their authenticity. CALCE provides component authentication and screening services through its Test Services and Failure Analysis Laboratory to verify the authenticity of parts.

Topics Covered

This two-part webtorial on parts inspection and materials characterization begins with a brief primer on the diverse counterfeit electronic part creation techniques, including the recently discovered “media-blasting” method. The webtorial then discusses the effectiveness of various non-destructive techniques and destructive processing steps for inspecting suspect counterfeit components that are created using diverse techniques. The case studies illustrate the use of an array of analysis techniques to assist in determining the authenticity of an electronic part.  Inspection techniques that are discussed in the webtorial include:

·        Optical microscopy
·        X-ray microscopy
·        Acoustic microscopy, decapsulation, die inspection
·        X-ray fluorescence (XRF) spectroscopy
·        Scanning electron microscopy (SEM) / energy dispersive spectroscopy (EDS)
·        Materials characterization tools (FTIR, IC, TGA, DSC, etc.)
·        Electrical testing

Who Should Attend?

Success Story in the fight to Combat Counterfeits








Electronic Supply Chain Solutions would like to inform those whom might be unaware  . . .                   
A Senate committee  meeting was  held  in Washington, DC during which Senator Levin promised a swift response to the growing problem to combat counterfeits. On November 29, 2011,  the U.S. Senate unanimously approved an amendment to the National Defense Authorization Act for Fiscal Year 2012. The legislation is supported by the bipartisan Combating Military Counterfeits Act which will ensure that increased penalties will be imposed against individuals who know that the counterfeit product they sell is intended for use by the military or is identified as a military device.

“To strengthen protections against counterfeit parts, the Levin-McCain amendment:

1. Prohibits contractors from charging the Defense Department for the cost of fixing the problem when counterfeit parts are discovered.

2. Requires the department and its contractors whenever possible to buy electronic parts from original component manufacturers and their authorized dealers or trusted suppliers who meet established standards for detecting and avoiding counterfeit parts.

3. Requires military officials and contractors who learn of counterfeit parts in the supply chain to provide written notification to the contracting officer, the Department of Defense Inspector General and to the Government-Industry Data Exchange Program.

4. Requires the Secretary of Homeland Security to establish a methodology for the enhanced inspection of electronic parts after consulting with the Secretary of Defense as to the sources of counterfeit parts in the defense supply chain.

5. Requires large defense contractors to establish systems for detecting and avoiding counterfeit parts, and authorizes reductions in contract payments to contractors who fail to do so.

6. Requires DoD to adopt policies and procedures for detecting and avoiding counterfeit parts in its direct purchases, and for assessing and acting on reports of counterfeits.

7.Adopts provisions of a bill sponsored by Sen. Sheldon Whitehouse, D-R.I., to toughen criminal sentences for counterfeiting of military goods or services.

8. Requires DoD to define the term “counterfeit part,” and at a minimum to include in that definition previously used parts represented as new.”

ESCS will monitor the follow up actions of this ammendmet and provide Quality Lessons Learned.

Are you in the dark when it comes to counterfeits?

Electronic Supply Chain Solutions is working day and night to help promote awareness about ways companies can midigate the risk associated with buying counterfeit electronic components. Many people turn to our site http://www.combatcounterfeits.com/ to learn the latest "tricks they play". ESCS known for thier Professor Quality has once again found new tecnology to "Combat Counterfeits.

While working in the dark Professor Quality discovered his finger print and everyone knows there are no two alike. That is where Alp Vision's "Fingerprint "is a real breakthrough in identifying genuine manufactured objects from fake ones based on digital images of the original product stored in a secure server. Fingerprint is based on a stored image which registers unique, microscopic differences generated by the manufacturing process and the raw material used.Digital imaging software identifies these unique characteristics of the image due to intrinsic differences even though objects are produced in series. Fingerprint is a Read Only solution which simply relies on the object "as is". It therefore cannot be counterfeited.

Typical applications are authenticating genuine mechanical parts of watches, automotive spare parts, medical devices and genuine spare parts of all kinds. Bottles, cans, flasks or other conditioning with metallic or plastic parts are also concerned.

Protect moulded or stamped parts:
Protect moulded or stamped parts that are mass produced objects such as Integrated Circuits (ICs) using a mould or using stamping techniques, the same unique “signature” will be present on all the objects produced with the same mould or using the same stamping tool. Therefore if a few moulds or stamps are used, only a few reference images are necessary. Toys, game chips, automotive parts, aerospace parts, electromechanical parts, and medicinal tablets are typical Fingerprint applications.

Contact AlpVision if you need to know more or how the Fingerprint solution can be applied to your Brand Protection and Gray Market Detection of your products.

Fingerprint is a trade mark of AlpVision SA and is part of the AlpVision digital imaging security solutions.

Lessons from the Automotive Supply Chain: Surviving a Downturn & How it May Effect the Aerospace Sector

Electronic Supply Chain Solutions provides this Article by Vince Pavlak as a quality lesson learned.
There have been numerous comparisons between the automotive and aerospace industries, and an October 2009 article from Aviation Week even asked, “Could Wichita become the next Detroit?” Many aircraft suppliers are learning from the automotive industry and some have recruited executives from the sector. Given the recent turmoil and challenges faced by the cyclicality of the automotive industry and its participants, the actions taken may provide valuable insights for the aerospace industry, which has historically also endured its share of volatility.
During the past 18 months, the automotive industry experienced one of the worst periods in its history. All industry participants, from original equipment manufacturers (OEMs) and suppliers, to automotive dealers, were affected. Suppliers experienced significant volume declines, immense liquidity constraints and a severe tightening of the credit markets. Few companies were adequately prepared, and all were required to adapt quickly to the new economic conditions and take significant actions to remain viable. This time period can truly be characterized as a fight for survival in which there were many casualties.
While the extraordinary government aid at the OEM level clearly helped to stabilize the industry, we have found that supplier survival came down to the following key factors…
Understanding customers, programs and parts
We are constantly surprised by how many suppliers believe they understand the profit generated on specific parts, programs and customers. However, after more thorough analysis, these gut feelings are often proven inaccurate. During a downturn, having a good understanding of where the profit is (and is not) can be critical to survival. In one example, we evaluated the standard cost and quote model for a $100 million supplier, noting the pricing model was omitting 20% of true cost, and that management was basing pricing and other critical strategic decisions on this flawed model.
As a supplier, it is also critical to understand which programs your parts ultimately end up on and which programs may be susceptible to market conditions or cancellation by the OEMs. Automotive suppliers that sold parts to the SUV and truck markets were more severely affected during the economic downturn than those that supplied more fuel efficient vehicles.
Managing and optimizing the cost structure
The best suppliers found creative ways to cut costs while mitigating negative impacts on the company’s longer-term prospects. Many suppliers were careful not to make cuts that affect the customer (e.g., sacrificing quality and delivery). Suppliers implemented numerous actions, including temporary wage/benefit reductions, in-sourcing of certain processing or services, improving asset utilization, and facility consolidation. While there was an obvious focus on reducing costs to conserve cash and enhance liquidity, we found the prosperous suppliers took this concept a step further by preparing an integrated cash flow/liquidity forecast model. This forecast model contained several key concepts, including (a) understanding product linkages to OEM programs, (b) sensitizing industry/OEM volumes and© flexing various cost structures. Suppliers with a deep understanding of their cost structure that were able to perform detailed financial planning were better equipped to manage through the downturn but more importantly, were proactive in developing plans and providing confidence to other stakeholders (lenders, customers, etc.) during the process.
Supply risk management
We believe that suppliers at all levels of the aerospace industry will receive increasing pressure from upstream customers (including the DoD) to proactively manage their supply base. Further, from a supplier standpoint, there will likely be more scrutiny on both the financial and operational metrics of the supplier’s business. An October 2008 Government Accounting Office report indicated that ”[the] DoD expects prime contractors to maintain internal corporate metrics to evaluate the health and performance of their subcontractors.” Further, Brett Lambert, the DoD’s director of industrial policy, noted:
“I’m worried about the second-, third- and fourth-tier vendors, the people who make the nozzles … that’s where we’re going to focus a lot of energy in the next few years.”
Ford Motor Company utilizes a Web-based system called Vontik as its global solution to gather more intelligence on its supply base, even going so far as to require suppliers to enter data prior to being awarded any new sourcing. It will be critical to ensure that suppliers at all levels are taking a proactive role in managing their own supply base, which includes understanding the extent of sole-source relationships, suppliers’ geographic footprints, contingency planning, etc. Providing comfort that there is a sound supplier management system in place might well become a criterion of future sourcing decisions.
Adapting (not abandoning) a longer-term business strategy
To prepare for a potential, or cope with an actual, down cycle, it is more critical than ever to understand the strategic direction of your company and how it aligns with the future marketplace. Making short-term decisions that are inconsistent with long-term strategy can be disastrous. Honest assessments of core competencies, manufacturing footprints, industry trends and technology shifts can provide valuable insight into the future direction of the company and its ability to be competitive. Also, it is crucial to maintain a convincing, viable, long-term plan; otherwise, customers may not be willing to source the company new work.
Being in the midst of a downturn represents an opportunity to re-evaluate the whole business model to refine the focus on delivering value. This evaluation could lead to the realization that a merger/acquisition is the preferred method for long-term growth and survival. Also, certain elements of the business that are without strategic or core value might present an opportunity for carve-out or liquidation.
Managing Debt and Liquidity

High debt levels prior to the automotive crisis caused many suppliers to end up insolvent. The suppliers that survived were able to maximize cash flows from working capital, as banks were not increasing exposure to the sector and in fact were more prone to exiting credits. Further, surviving suppliers were more sophisticated in terms of preparing flexible financial forecast models and reducing cash outflows. This allowed these suppliers to understand and plan for potential upcoming issues with their debt, whether it was the specific amount and timing of repayment, covenants or liquidity constraints.
While there now appears to be some loosening of credit and more willingness on part of lenders to work with troubled credits, the markets generally are still tight, and borrowing costs remain high, especially for lower tier suppliers. Ironically, many automotive suppliers are now experiencing liquidity constraints trying to fund the working capital needs and requisite capital/tooling expenditures as the industry slowly begins to recover and volumes increase.

In summary, those suppliers that were able to demonstrate the above factors were more likely and better positioned to survive the recent automotive downturn. Automotive suppliers actually are emerging from the downturn better positioned with lower cost structures, improved balance sheets, more reliable supply chains, fewer competitors and an enhanced mix of product offerings. While these principles have proven valuable during the crisis in the automotive industry, they can be applied to aerospace suppliers, as well, and are useful even during times of prosperity. Suppliers that demonstrate viability through the aforementioned key factors can make it clear to customers and other key constituents that they are well positioned for long-term success and, as such, are more likely to be chosen as winners in the long-term battle for survival.
