Advanced Materials for Microelectronic, Optoelectronic and MEMS Packaging and Thermal Management

Instructor:
Dr. Carl Zweben, Composites Consultant

Course Description:

Materials selection impacts performance, reliability and cost.  Increasingly, the traditional materials used in microelectronic packaging are failing to meet the requirements for optoelectronic and MEMS packaging, as well as those of new microelectronic system designs.   In response, numerous advanced composites and monolithic materials have been, and are continuing to be developed.  Property improvements include:

   extremely high thermal conductivities (over four times that of copper)

   low, tailorable coefficients of thermal expansion

   extremely high strengths and stiffnesses

   low densities

   low cost, net shape fabrication processes

Payoffs include:

   improved fiber alignment

   reduced thermal stresses and warpage

   lower junction temperatures

   simplified thermal design

   possible elimination of heat pipes

   weight savings up to 80%

   size reductions up to 65%

   increased reliability

   potential cost reductions

These materials provide the engineer with greatly expanded design options.  Costs are continuing to decrease, making composites increasingly economically attractive.  For example, some parts made of Al/SiC, a metal matrix composite first used in optoelectronic and microelectronic packaging by the instructor in the 1980s, are now selling for the same price as the copper ones they replace.  Use is increasing 10% annually.  Newer materials offer significant advantages over Al/SiC.  Advanced composites and monolithic materials will be the packaging materials of choice in the 21st century.

Advanced materials, such as Al/SiC metal matrix composites and carbon fiber-reinforced polymer matrix composites, are now being used in a growing number of high volume commercial and aerospace production applications at the rate of millions of piece parts annually.  The expanding list of components includes carriers, heat spreaders, pin-fin heat sinks, solid and flow-through PCB cold plates, microwave modules, power semiconductor modules, and heat pipe overmolds.  Products using these materials include cellular telephones and base stations, laptop computers, hybrid and electric vehicles, data storage drives and aircraft and spacecraft electronic systems.

This course provides an in-depth discussion of the materials, their properties, the processes by which they are made, and where they are being used.  We also look at future directions in the technology.

Who Should Attend?

Engineers, scientists and managers involved in microelectronic, optoelectronic and MEMS packaging design, production and R&D.  Packaging material suppliers.

The long-term reliability of surface mount (SM) solder interconnections remains an important issue in advanced electronics packaging technologies.  The development of high-reliability SM circuit assemblies requires an understanding of the key reliability challenges and controlling design parameters.  This intensive course describes the reliability hazard for SM connections and presents practical methods for SM attachment reliability assurance.  These risk-mitigation processes support the needs of the electronics packaging R&D community, by providing robust design strategies without requiring a detailed understanding of complex SM reliability issues.  Major topics include:

   Reliability hazard for SM connections, driven by the component-to-substrate mismatch in coefficient of thermal expansion (CTE) and strain-induced fatigue damage.

   Solder thermo-mechanical behavior during cyclic loading, and related fatigue damage induced by stress relaxation and creep.

   Case studies of at-risk and failed SM connections.  Industry examples of non-robust SM assemblies resulting from materials CTE incompatibility, insufficient lead compliance, gold-tin intermetallics, marginal solder joint quality, and aggressive mechanical loads.

   Practical lead compliance evaluation process and specialized stiffness metric for corner-most leads, corresponding to the location of the relatively high-risk SM connections.

   Effect of lead compliance on SM attachment reliability, demonstrated via fatigue life statistics from industry accelerated testing programs.

   Representative commercial high-compliance lead designs that can mitigate the SM attachment reliability hazard.

   Weibull failure probability distribution for wear-out processes, as this statistical model relates to SM attachment fatigue failure.  Representative Weibull failure statistics for recognized at-risk SM packages, including TSOPs and BGAs.

   Design-for-Reliability (DFR) tool for SM attachment, covering capabilities, technical foundation, application criteria, and limitations.

   Strategies for robust SM attachment, based on the interaction of package design, assembly technology, operational thermal environment, and product service life.

   Practical applications of the DFR tool for SM ceramic discrete components, selected SM leaded packages, and BGAs.

Microvias and Embedded Passives

Instructor:
Dr. Rolf Funer, Ph.D., Industry Consultant

Course Description:

New PCB designs are requiring more and more component placements, more I/Os, tighter dimensions. Microvias can dramatically reduce board size, increase I/O count and reduce layer count. The numbers of passives: resistors and capacitors are increasing dramatically. By embedding the passives directly in the circuit board, valuable surface area can be saved. And performance, particularly at high frequency, can be improved. These new technologies can work together to cut weight and size—and ultimately cost. But can these concepts be implemented today? Or are they future technologies? This workshop addresses these issues, reviews all the currently available materials and processes to make microvias and embed passives. Design and testing issues, performance, reliability, applications and economics are all covered. The design and project managers attending this course will come away with an informed view if their designs are ready for microvias and embedded passives and if microvias and embedded components are ready for them. PCB manufacturing and development engineers will learn what they will need to do to implement these technologies.

Failure Analysis of Hybrid Microelectronics Packaged Devices from a Materials Perspective

Instructor:
Andrew M. Hirt, Materials Research Laboratories, Inc.

Course Description:

In the last few years, hybrid microelectronics devices have undergone a dramatic change in the scope of materials associated with them.  In the past, a hybrid device generally consisted of a ceramic substrate mounted in a metal package and contained surface mount devices on a pattern that was screen printed over the ceramic.  The circuitry was generally encased in a metal package and hermetically sealed for protection.  The new ‘hybrid’ can be a composite of almost any materials.  Current substrate materials include ceramics, epoxy-glass circuit boards, flexible metallized polymers, plastics and anything else to which someone can find a way to attach a circuit pattern.  Packages may be metals, ceramics, plastics, epoxies or missing altogether. With this no-holds-barred attitude toward applicable materials, the ability to perform a successful failure analysis study becomes much more difficult.  Adding to the problems associated with failure analysis studies is that the hybrid has moved from primary usage in military and aeronautics applications to virtually any item that requires some form of electronic control.  The local environments have expanded to the very harsh while the protection provided many hybrid circuits by encapsulation or sealing have diminished.  A benefit to the overall performance of current hybrids is that the problems are generally identified, corrected and implemented quickly.  A further downside, however, is that tracking the problem that caused the failure to its root source may involve several industries, shipments and plants, many of which may not have the needed records, retains, etc., that can produce useful results.  In addition to the proliferation of problems associated with hybrid production, the number of analytical tools available to the failure analyst has expanded.

This short course will provide a structured approach to the failure analysis of hybrid microelectronics devices.  The course will include discussion of the selection of analytical protocols and techniques and the interpretation of results.  The information presented will offer insights into the root cause of failures from the materials perspective.  These might include original design faults (usually assumed to have been eliminated prior to production implementation), materials failures due to processing (mechanical, chemical, etc.) or environment, shipping and handling damage, etc.

Who Should Attend?

This course will be useful to those involved in the analysis of hybrid microelectronics devices that have experienced failures, particularly for unknown reasons after prior successful manufacture. Members of electronics design groups, quality control departments and research and developments groups.  Course notes will be provided.

Seminars, Inc.

Course Description:

This course will detail both the critical electrical and critical non-electrical parameters, which are vitally important to success in modern electronic assemblies and systems.  In addition, the material presented will discuss the various substrates, especially circuit boards and ceramic substrates, and will address the new, high performance substrates.  Tradeoffs for these substrates will be presented along with advantages and limitations of the high performance substrates.  Other materials and material forms which are critical in today’s high packaging density, high speed circuitry, and other high performance parameters will also be discussed.

For critical electrical parameters, the key electrical properties will be defined and illustrated, and the effects of major operating environments will be explored.  Discussions will cover all electrical functions, including resistance and resistivity, voltage, and loss functions such as dielectric constant and dissipation factor and their variations.  Often not understood anomalies of these functions will also be reviewed.

For critical non-electrical parameters, discussions and explanations will parallel those listed above for critical electrical parameters.  Particular emphasis will be placed on properties of importance in the highly sensitive operational environment of thermal excursions, which almost always lead to failure problems in electrical equipment.  These properties include thermal expansion, thermal stability and thermal life, and thermal conductivity.  Methods for optimizing materials performance will be discussed.  Other critical operating environments, and materials performance in these environments will be analyzed, along with methods for optimizing performance.

Who Should Attend?

This course will be useful for all of those interested in understanding critical materials properties and the performance and optimization of materials for important operating environments.  This includes engineering, manufacturing, process, quality, marketing, and others involved in development, design and manufacture of electronic assemblies and systems.

Fundamentals of Fabrication and Packaging of MEMS and Related Micro Systems

Instructor:
Ajay P. Malshe, Ph.D., University of Arkansas

Course Description:

This introductory course will cover packaging and integration of micro-electro mechanical systems (MEMS). Unlike integrated circuit (IC) packaging, MEMS packaging is highly application specific. MEMS and related micro systems are designed, fabricated and packaged for various applications, for example accelerometers, gyros, RF switches, optical switches, micro fluidic drug delivery systems, etc. Moreover, growing trend demands multifunctional systems where integration of these diverse signals results into true “mixed signal systems.” Hence, a growing number of products need application- specific design, materials, fabrication and assembly processes for building reliable MEMS systems.

The course has two sections. The first will introduce and discuss fundamentals of various MEMS and related microsystem products, and their packaging and assembly requirements. It will further touch upon the basics of surface and bulk micro machined MEMS fabrication processes including M4 techniques and various materials used to make these devices. The second part will discuss in length classification of MEMS packaging processes, packaging and assembly issues such as dicing, stiction, interconnection, out gassing, ambient specific packaging, reliability, etc. The course concludes with a discussion of MEMS market and manufacturing trends.

Who Should Attend?

MEMS and related micro systems packaging business offers new opportunity to traditional IC packaging scientists, engineers and businesses. Further this area is evolving rapidly and hence, understanding the fundamentals is key for developing and packaging reliable products. Thus, this course is useful to scientists, engineers and business managers working in the areas of designing, fabrication, assembly, testing, and marketing of materials, software, equipment and processes for MEMS and related products. Also, this course will benefit people looking for new business opportunities, which are there worldwide.

Area Array Technology – Processes, Materials, Packages and Reliability

Instructor: 
Dr. Wayne Johnson, Ph.D., Auburn University

Course Description:

The increasing number of I/Os (inputs/outputs) per semiconductor chip combined with the product driven requirements of thinner, smaller and lighter weight have led the electronics packaging and assembly industry to area array packages and assembly. The new area array package and assembly approaches are replacing the traditional perimeter approaches: quad flatpacks (QFPs) by ball grid array (BGAs), thin small outline packages (TSOPs) by chipscale packages (CSPs) and chip-on-board (COB) by flip chip on laminate (FCOL). This course will begin by examining the drivers for area array packaging, then examine the packaging options, their construction and trade-offs. Substrate design requirements will be discussed including routing, pad design and the reliability impact of design. Major assembly issues are flux selection, underfilling, if necessary, and inspection. Underfilling which is not a traditional SMT assembly process is required for FCOL and often for CSPs. The underfill process and material options will be examined. Recently, wafer applied underfill material concepts for FCOL assemblies have been discussed and this new technology concept will be explored. The course will conclude with a discussion of packaging reliability. The replacement of leads by solder spheres impacts reliability, particularly in thermal cycling and bending, and must be considered prior to implementing area array technology.

Who Should Attend?

This course is designed for staff members, technical managers, supervisors, systems designers, and manufacturing engineers in companies using or planning to use area array packages or flip chip. Materials and equipment suppliers for area array assembly will also benefit by gaining necessary background information.
