EEE 498/598Overview of Electrical Engineering Lecture 1: Introduction to Electrical Engineering Lecture 1 Objectives To provide an overview of packaging. To review the electrical functions of a package. To understand the foundations of electrical engineering. To become aware of the topics that will be covered in this class. To define the coordinate systems that will be used in this class. Overview of Packaging Overview of Packaging Overview of Packaging “Packaging engineers today must solve complex, coupled problems that require fundamental understanding of electrical, thermal, mechanical, material science, and manufacturing principles.” Dr. Nasser Grayeli, Intel Corporation This course focuses on preparing students to understand the electrical principles. Electrical Functions of the Package Power Delivery Supply a clean power and reference voltage to active devices on the die. Signal Input/Output Transmit signals from the die to the motherboard faithfully and in minimum time. EMI/EMC Minimize radiation of electromagnetic energy into the environment, and the impact of ambient electromagnetic energy on circuit performance. Foundations of Electrical Engineering Electrophysics. Information (Communications) Theory. Digital Logic. Foundations of Electrical Engineering Electrophysics: Fundamental theories of physics and important special cases. Phenomenological/behavioral models for situations where the rigorous physical theories are too difficult to apply. Hypothesis, Model, and Theory A hypothesis is an idea or suggestion that has been put forward to explain a set of observations. It may be expressed in terms of a mathematical model. The model makes a number of predictions that can be tested in experiments. After many tests have been made, if the model can be refined to correctly describe the outcome of all experiments, it begins to have a greater status than a mere suggestion. A theory is a well-tested and well-established understanding of an underlying mechanism or
