CALCE has made available years of research as webbooks, which are intended to provide a knowledge and resource base to support the development of competitive electronic components, products, and systems. 

Encapsulation Technologies for Electronic Applications
More than 99% of today’s microelectronic devices are encapsulated in plastic. Recent improvements in materials and cost incentives have expanded the application boundaries for plastic electronic packages so that many electronic applications once enclosed hermetically are now enclosed in commercial-off-the-shelf (COTS) packages. The obvious advantages are low cost, smaller form factors, and improved manufacturability. Encapsulation Technologies for Electronic Applications is primarily focused on the encapsulation of microelectronic devices, with additional attention paid to the encapsulation of connectors and transformers. Various encapsulation techniques are explained including molding, potting, glob-topping, underfilling and printing encapsulation. Other topics discussed include 2-D and 3-D packaging, materials (including those considered to be environmentally friendly or “green”), properties and characterization. Furthermore, this book addresses the defects and failures related to encapsulation, how to properly analyze them, and how to apply proper quality assurance and qualification processes. It also provides up-to-date information on the trends and challenges of encapsulation and microelectronics packages, including in the application of nanotechnology.

Accelerated Product Qualification and Quality Assurance 
This online resource presents interactive reliability science guidelines for accelerated product qualification and quality assurance.  The material is intended to give electronics manufacturers, suppliers, managers, analysts, and engineers a rational understanding of efficient ways to assess product durability and quality. Further, the fundamental concepts required to develop a successful reliability science based accelerated qualification and quality assurance program that meets the product requirements, lowers life-cycle costs and reduces the time-to-market are addressed in detail through interactive case-studies. The valuable lessons learned are outlined as a set of generic guidelines to help design, plan, and implement a reliability science-based accelerated qualification program. Contacts: Dr. Abhijit Dasgupta, [software, presentations, tutorials, case studies, and reports].

Circuit Card Assemblies Failure Mechanism Handbook

This resource describes, compares, and critiques different failure models for CCAs. Examples include thermomechanical fatigue, vibration fatigue, mechanical shock/warpage damage, and chemical/corrosion damage. Access to online failure calculators is also provided. Contact: Dr. Michael Osterman, [software, presentations, tutorials, and reports].

Component Knowledge Base 
The component knowledge base webbook was developed to provide engineers with valuable background information on a variety of components including analog ICs, connectors, memory, potentiometers, cables, electromotors, MEMS, resistors, capacitors, magnetics, PCBs and thermistors which are used in electronic products. This webbook is intended to aid engineers in: (1) identifying critical components in a product based on system application requirement and component technologies, (2) understanding design and manufacturing (construction, material, reliability, quality issues) of these components, (3) analyzing risks related to the application of these components, (4) evaluating identified risks using analytic and reliability test methodologies, (5) developing component reliability and quality specifications, (6) developing guidelines for proper application of the components in system design, manufacturing, and test, (7) identifying root-cause of failures related to the components, and (8) investigating component quality/reliability function enhancement and cost reduction opportunities. Contact: Dr. Diganta Das.

Contacts, Connectors and IC Component Sockets

It provides: a physical understanding of separable contacts; a comprehensive overview on connector and socket materials and their properties; a detailed examination of performance characteristics; an extensive examination of socket designs; a process for reliability assessment of IC component sockets; a complete discussion on failure modes and mechanisms; a list of industry specifications and standards; and much more. Contacts: Dr. Michael Pecht and Dr. Diganta Das , [tutorials with references, bibliography and internet links].

Contamination of Electronic Assemblies
New components, designs, materials, and assembly processes have caused contamination problems to become a major factor in determining the manufacturability, quality, and reliability of electronic assemblies. Understanding the mechanics and chemistry of contamination has thus become necessary for increasing quality and reliability, and reducing the costs of electronics assemblies. Contacts: Dr. Michael Pecht

Contract Assembly Assessment 
The growth in popularity of contract assembly outsourcing in the electronics industry and the absence of concrete procedures for the outsourcing process form the motivation for this research work. Contract outsourcing involves the transfer of specific assembly activities related to a product or process from an OEM (Original Equipment Manufacturer) to a CA (Contract Assembler). This web site presents industry outsourcing data from the top OEMs and CAs, step-by-step procedures for performing benchmarking and the management of the CA, the economics of outsourcing, and several case studies of large OEMs that have successfully performed outsourcing of electronics assembly activities. Contact: Dr. Peter Sandborn, [presentations and case studies].

Design Refresh Planning (MOCA) Software 
A methodology and it’s implementation (MOCA) has been developed for determining the part obsolescence impact on life cycle sustainment costs for the long field life electronic systems based on future production projections, maintenance requirements and part obsolescence forecasts. Based on a detailed cost analysis model, the methodology determines the optimum design refresh plan during the field-support-life of the product. The design refresh plan consists of the number of design refresh activities, their respective calendar dates and content to minimize the life cycle sustainment cost of the product. The methodology supports user determined short- and long-term obsolescence mitigation approaches on a per part basis, variable look-ahead times associated with design refreshes, and allows for inputs to be specified as probability distributions that can vary with time. Outputs from this analysis are used as inputs to the PRICE Systems PRICE H/L commercial software tools for predicting life cycle costs of systems. Contact: Dr. Peter Sandborn, [application software and documentation].

Electrochemical Migration 
Electrochemical migration (ECM) is defined by the Institute for Interconnecting and Packaging Electronic Circuits (IPC) as the growth of conductive metal filaments on a printed circuit board (PCB) through an electrolytic solution under the influence of a DC voltage bias [IPC-TR-467A, 1997]. ECM can occur between leads and interconnects, connector pins, electrodes in a capacitor, and traces on a PCB. ECM is considered primarily a surface phenomenon, so as to differentiate it from conductive filament formation (CFF) which occurs internal to the circuit board. Contacts: Dr. Michael Pecht

Escape Routing and Footprint Analysis 
A limiting requirement for some parts is escape routing. If a part's I/O are in an area array format (as opposed to peripherally bonded), the part can not be wired into the system until all of its I/O are routed out from under the part. This situation is encountered for flip chip bonded die and die in various array format chip scale packages such as BGAs (Ball Grid Arrays). The process of liberating I/O from an array is called escape routing.  If the array is small enough (small I/O count), or the line width and line spacing in the board is fine enough, it may be possible to escape all the I/O on the top layer of the board. More often, However, some I/O must use vias to drop to other layers to be escape routed.  If additional layers must be used, the combination of the part I/O pitch and connection size, and the via and/or hole capture pad sizes must allow the placement of a via or hole capture on the board within the part I/O array, or it is impossible to drop unescaped I/O to deeper layers. In addition, many board technologies, especially microvia Printed Wiring Boards (PWBs), have practical limitations on the number of layers that can be fabricated. A part that requires too many layers to escape route may have to be rejected.  This tool can be used to: 1) Determine whether a specific part can be escape routed when interconnected to a specific board technology, and 2) Determine the footprint occupied by the part on the top layer of the board.

Material Hardness 
The Metals Handbook defines hardness as "Resistance of metal to plastic deformation, usually by indentation. However, the term may also refer to stiffness or temper, or to resistance to scratching, abrasion, or cutting. It is the property of a metal, which gives it the ability to resist being permanently, deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Contacts: Dr. Keith Rogers [books chapters with references].

Contact: Dr. Peter Sandborn, [software, guidebook, and references].

Liquid Crystal Display: Performance and Reliability
Display technology is changing at an ever increasing pace. New developments focused towards optimizing power, size, weight, performance and cost are revolutionizing the display industry. The flat panel display market is projected to be around $30 billion worldwide in 2003, of which 86% is expected to be liquid crystal displays. Furthermore active matrix LCD are projected to be the dominant LCD technology in the coming years. Apart from consumer electronics, increasing use of LCDs in critical applications like defense, avionics and automobiles has evoked the need to understand the reliability of LCD devices. This web handbook is part of this effort to bring together all the scattered data on LCD reliability at one place for the benefit of CALCE consortium members. Contact: Dr. Patrick McCluskey and Dr. Bongtae Han, [book chapters and references].

Long Term Non-Operating Reliability of Electronic Products 
Electronics can experience a range of environments subsequent to manufacture and prior to disposal. Non-operating electronics do not necessarily experience benign environments. The potential environmental stresses on non-operating electronics can be natural, such as those due to climatic conditions, or can be induced by humans. This book examines non-operating electronics reliability issues, outlining and discussing storage conditions, the stresses that can arise in these conditions, and the failure mechanisms that can cause a failure.

This book addresses the major facets of modern soldering technology and the science behind that technology. Contact: Dr. Michael Pecht [books chapters with references].

Rating and Uprating of Electronic Parts
Uprating is a process to assess the capability of an electronic part to meet the functional and performance requirements of an application in which the part is used outside the manufacturers' specified operating conditions. In an ideal world, there would not be a need for a book on uprating. The part manufacturers would supply parts with appropriate ratings, for all products and systems. One would not have to be concerned about using any part beyond its ratings. Also performance, cost, assembly, test and obsolescence would not be factors of concern. However, the ideal world does not exist. Contact: Dr. Diganta Das, [book chapters and references].

Wiring Harness Failure Mechanisms 
This document considers mostly wires for electronics rather than wires used for the conduction of electrical power (in such applications as power distribution, home and building service, and appliance and machine wiring). Although the products for these two general applications areas are quite similar, wires for electronics must be functional over a wide range of frequencies from direct current well into the millimeter wavelengths. By contrast, power distribution wires are primarily intended to carry direct current or alternating current at 50/60 Hertz. Certain kinds of products (such as flat ribbon wiring, coaxial cable, and fiber-optic cable) are used exclusively in the domain of electronics, and power cords are common to both market divisions. However, as electronics invades more products and applications, the distinctions begin to diminish, as wires that carry both power signals become more prevalent.
