S2
Flip Chip and CSP Technologies – Constructions, Materials, Assembly and Reliability
Course Leader:
R. Wayne Johnson, Ph.D., Auburn University

Course Description:
The increasing number of I/O per semiconductor chip combined with the product driven requirements of thinner, smaller and lighter weight have lead the electronics packaging and assembly industry to chip scale packages and flip chip (Flip Chip in Package (FCiP) and Flip Chip on Laminate (FCoL)) technologies. In fact, many CSPs use FCiP constructions. This course will begin by examining the drivers for flip chip and CSP technologies, then examine the options, their construction and trade-offs. 3-D CSPs will also be examined. Substrate design requirements will be discussed including routing, and pad design. Major assembly issues are flux selection for flip chip, solder paste printing for CSPs, underfilling, if necessary, and inspection. Underfilling which is not a traditional SMT assembly process is required for flip chip and often for CSPs. The underfill process and material options for flip chip and CSP will be examined. Recently, wafer applied underfill material concepts for FCoL assemblies have been discussed and this new technology concept will be explored. The replacements of leads by solder spheres impacts reliability, particularly in thermal cycling and bending, and must be considered prior to implementing these technologies. The course will conclude with a discussion of reliability.

Who should attend?
This course is intended for those individuals soon to be responsible for implementing flip chip assembly, suppliers of materials and equipment for flip chip assembly and others interested in flip chip implementation.

S3
The Integrated Circuit – The Packaging, Assembly, and Interconnections
Course Leader:
William J. Greig, Greig Associates

Course Description:
This course provides an overview of electronics/microelectronics manufacturing and addresses the impact of both the Integrated Circuit and End Product, i.e., “smaller, better, cheaper.” It covers IC packaging, chip assembly, and HDI packages and substrates. It focuses on packaging trends, in particular area array, namely the BGA, the CSP, and the Flip Chip. Flip Chip and its counterpart the Wafer Level CSP, are discussed and evaluated as an IC “package” and an assembly technology. It discusses advantages of alternative packaging options including multichip packaging (MCP), and Chip On Board (COB). Emerging 3-D packaging initiatives rapidly entering mainstream are examined at both the chip and package levels, i.e., both die and package stacking.

High Density Interconnect (HDIs) packages/substrates manufacturing process technologies are reviewed including Thick Film, Co-fired Ceramic, and Thin Film that support Level 1.0 SCP and MCP and Level 2.0 PWBs. In the later case, significant developments in the PWB process technology are presented including Build Up Technologies (BUT) that offer increased wiring density, fine lines and spaces, and microvias.
Throughout the course, technical issues will be emphasized and reliability concerns addressed where appropriate.

Who should attend?
The course is effectively a primer covering primarily the microelectronic packaging arena. It is intended for a variety of individuals, technical and non-technical, whether directly or indirectly involved with electronic product manufacturing. It will serve as a review of current and emerging technologies for the experienced engineer and technician or as an introduction to the various technologies for anyone new to the industry. It should be of particular interest to those in support activities, such as procurement, quality assurance, marketing and sales, by providing an adequate technology base for evaluating, planning or implementing.

S4 - New Course
Microwave & Millimeter Wave Packaging; Basics, Materials and Processes
Course Leader:
Aicha Elshabini & Fred Barlow, University of Arkansas

Course Description:
Today a wide range of applications require circuits or circuit elements which process high frequency information in the radio wave frequency band, as well as in the microwave range (300 MHz-30 GHZ) and the millimeter wave frequency range (30 GHz-300 GHz). These applications are rapidly growing and include communication devices such as cell phones, wireless networking, as well as a wide range of radar and electronic warfare applications. These types of applications often are associated with unique challenges not found in digital or low frequency circuits. In many cases the packaging considerations are fundamentally different in these frequency ranges.

This course will serve as an introduction to package design, fabrication, and testing for microwave and millimeter wave applications. It will cover the basic issues that make high frequency circuits unique, as well as planar transmission line structures; their design, and behavior. Materials and fabrication technologies applicable to high frequency circuits will be discussed in detail. In addition, the design of passive structures to achieve common electrical functions such as filters, couplers, inductors, capacitors, etc., will be covered. Finally, methodologies for the design and simulation of structures and circuits will be described as well as methods for the measurement and characterization of their electrical properties.

The course will also touch on the latest trends in this area such as MEMS switches, and the latest advances in MMIC and wideband gap semiconductors such as GaN.

Who should attend?
Engineers, managers, and technicians, who wish to expand their background or strengthen their understanding of the Microwave and Millimeter Wave technology. The course will not assume any prerequisite background.
