• How To Avoid Being The Next Toyota – Safety Society 2011 – Mike Silverman – Presentations
  By Mike Silverman
  IEEE Reliability Chapter Chair and Managing Partner, Ops A La Carte
  • Toyota has been in the news for the gas pedal issue for a number of months.
  • This month, the Quality Progress magazine had a number of articls about this issue, discussing it to be a Quality Problem
  • Tonight the intent is not to figure out what Toyota needs to do differently but rather to see how other companies can avoid falling into the same trap.

ESS Presentations

New Techniques for More Effective ESS

By: Mike Silverman, Managing Partner
Introduction
This presentation will focus on the best methods for developing and maintaining a HASS.
There are many different types of ESS programs and many different types of stresses companies use, including run-in, burn-in, temp cycling, and HASS
• When choosing a method, we must do two things:
• 1) assure the screen is able to find defects
• 2) assure the screen is not damaging
• Given these two, one of the best types of ESS is HASS.

FMEA Presentations

FMEA on FMEA by Mike Silverman – Presentations

by Mike Silverman, CRE, Ops A La Carte, LLC
• Failure Modes and Effects Analysis (FMEA) is a systematic technique of identifying, analyzing and preventing product and process problems before they occur.
• When implemented properly, FMEA’s is one of the most valuable reliability and design tools.
• Improperly executed causes FMEA’s to be a waste of resources and time. Worse, it could steer you in the wrong direction.

Green Reliability – RAMS 2011 – Presentations

“Going green” is a term that is increasingly used, is not well understood, and has many economic and technical implications – from the materials being used to the type of energy being used, and the quantity being consumed. Each aspect of going green also has reliability implications due to the inherent reliability risks that arise when we change material properties or design concepts. Companies have yet to address the reliability aspects when going green.

Without established taxonomies for design of environmentally friendly products, the “Green Revolution” will come and go without much impact on our environment. And even the standards that are being developed do not address the topic of reliability. If a product fails prematurely, the standards call out how to dispose of the product, but reliability engineering may offer solutions for preventing it from failing in the first place.

This paper will explore different green industries and the role of reliability. Some of the industries that will be explored are solar, wind, telecom centers, electric meters, electric vehicles, and fuel cells. Reliability engineering is going to play an important role in all of these industries because they are trying to replace an incumbent and must be as good or better. Some of the emerging reliability demands are:

• Higher Reliability Demands
• Higher Availability Demands
• Higher Warranty Requirements
• New Materials/New Risks
• Pressure on reducing power

For each industry the paper will explore the potential risks (in the form of failure modes), some of the consequences of these risks (failure effects), and which reliability techniques can be used to mitigate these risks.

Green is an increasingly common theme in product campaigns and marketing, including new symbols, slogans and pictures. Numerous websites today make claims such as “we are going green”.

The U.S. government has promoted green standards, such as EPEAT. EPEAT evaluates electronic products in relation to 51 environmental criteria, including 23 required criteria and 28 optional criteria. To qualify for registration as an EPEAT product, the product must conform to all the required criteria. Depending on the number of criteria a company conforms to, there are different EPEAT marking. Figure 2 shows the different markings:

EPEAT sets standards for:

• Reduction/elimination of environmentally sensitive materials
• Materials selection
• Design for end of life
• Product life cycle extension
• Energy conservation
• End of life management
• Corporate performance
• Packaging

Notice that there are no standards set for quality or reliability. If the product fails prematurely, they promote proper disposal, but why not work on preventing it from failing in the first place?

From HALT Results to an Accurate Field MTBF Estimate, the HALT Caculator – RAMS 2010 – Harry McLean and Mike Silverman – Presentations

Summary & Conclusions
As HALT takes only a few days to run and to implement its corrective action(s), and even if it takes a bit longer, this time would be far less than waiting for an RT to be run and to implement its corrective action(s). This paper discusses a mathematical model which can be a huge time and cost saver. By not performing life tests and simply doing an effective HALT, time and money will be saved.

What is HALT and what is Not HALTWhat Is HALT?
(and What Is Not HALT?)
By Mike Silverman, CRE, Managing Partner, Ops A La Carte

Reliability is no longer a separate activity performed by a distinct group within the organization. Product reliability goals, concerns and activities are integrated into nearly every function and process of an organization. Each organization must factor reliability into every decision in order to ensure produce a successful product.

The old Test-Analyze-and-Fix philosophies no longer have a place in today’s design process due to continuous cost reduction pressures and reduced design cycles. The motivation to implement a Design for Reliability (DfR) process include:

• Higher Demand for Reliability that cannot be achieved using previous reliability techniques

• Faster time to market

• More emphasis on reducing cost

• Fast moving technology, which creates new risks to development programs.

Successful implementation of the DfR process will reduce the product development cycle, lower the design cost, and improve customer satisfaction.

Reliability professionals these days are becoming more and more familiar with the term Design for Reliability (DfR). Increasing number of companies advertizeDfR as part of their design process and more and more web-based and life training is offered on the DfR methods. However, what truly is Design for Reliability• Despite the previous work done on this subject (see [1], [2] and [3]) DfR has not yet been fully defined. It is still a work in progress. In an attempt to clarify the subject of DfR this paper discusses what does and what does not constitute the Design for Reliability process and lays out the key steps in achieving a reliable design.

Since this term is often misused and misplaced, let us first define what the Design for Reliability is not:

• Making a list of all possible reliability activities and then trying to cover as many as possible within the timeframe of the product development process.

• Using only certain selected tools from the “DfR toolbox” (see Section 2 for more details)

• Assuming that product reliability is the sole responsibility of a reliability engineer (reliability engineer is the guide and mentor but not the owner -designer should be the owner).

• Completing the analytical work but delay test and verification until the system testing stage.

• Getting the product into test as fast as possible to test reliability into the product (Test-Analyze-and-Fix)

• Only working on the in-house design items and not worrying about vendor items

• Working in silos between Electrical, Mechanical, Software and other functional areas (even if they apply some or most of the DfR tools).

• Not looking at interactions between groups and not taking a system level viewpoint.

Design for Reliability (DfR) is an emerging discipline that refers to the process of designing reliability into products as opposed to the Test-Analyze-and-Fix philosophy, which unfortunately still exists in today’s design process. DfR encompasses several tools and practices and describes the order of their deployment that an organization needs to have in place in order to drive reliability into their products. Specifically, DfR is:

• A process which begins from the very early stages of the design and should be integrated into every stage of this process.

• Setting goals at the beginning of the program and then developing a plan to meet the goals.

• Having the reliability goals being driven by the design team with the reliability team acting as mentors.

• Providing metrics so that you have checkpoints on where you are against your goals.

• Writing a Reliability Plan to drive your program.

• The process which begins from the very early stages of the design and should be integrated into every stage of this process

• Using the best available science-based methods to achieve reliability.
