The economics of electronics and embedded system development have changed significantly over the last decade. Many local industries which do not maintain full-time electronics development staff have demanded that electrical engineering graduates support small-scale custom electronic development efforts, and projects that previously would have been contracted are increasingly handled internally. The same developments that have driven demand for custom electronics in industry have made it flexible and affordable to deliver a project-based PCB design course in a single semester. XXX University offers an electrical engineering senior elective course covering project specification, software/firmware development, CAD layout, PCB fabrication, surface-mount (SMT) assembly, circuit testing, remediation, integration, and packaging. Over the course of a semester, student teams design, assemble, test, package, and demonstrate unique embedded system projects.
This paper presents the benefits and challenges of teaching and administering a design-build-test embedded system project course in electrical engineering and addresses plans for ongoing improvement. The course instructs students in each element of an electronics development project. This starts with recognizing electronics problems, specifying critical design functionalities, identifying constraints, anticipating risks and failure modes, and designing for test and remediation. During the course, students receive instruction in proper firmware coding techniques, common electronic circuits and practices, component selection, power regulation, ADC functionality, transmission line theory, signal integrity, layout guidelines, and PCB fabrication techniques each of which the students apply to a semester-spanning project. Student teams order custom PCB boards from commercial vendors, assemble circuits with SMT technology, program, test, and remediate their electronic projects. This paper analyzes the effectiveness of this course, considers feedback, and makes recommendations for future offerings.
