Printed Circuit Board

Design, Fabrication, Assembly and Testing

Course No. 472

(Course Outline shown below.)

For Whom Intended This course is intended for personnel involved in designing, testing and manufacturing printed circuit boards. Degreed engineers whose primary training is not in this field will benefit, as will technicians, quality assurance inspectors and manufacturing engineers. The course will also benefit managers and supervisors in charge of these functions.

Brief Course Description The course follows a step-by-step approach to the deve-lopment and manufacturing cycle of a printed circuit board. After an overview of standards and existing technology, the course discusses the various engineering functions involved in PCB design and manufacturing. Specific issues are addressed in the areas of manufacturing and assembly, before moving on to PCB testing and quality assurance. The course addresses the potential pollution and safety impacts of PCB manufacturing, as well as applicable standards.

Diploma Programs This course is a recommended optional course for TTi’s Electronic Design Specialist (EDS) Diploma Program, and may be used as an optional course for any other TTi Specialist Diploma Program. Any TTi course may be presented on-site, at your facility.

Related Courses TTi is developing a complete PCB design curriculum, including Course 473, on mechanical, structural and thermal considerations and layout, Course 474 on electrical considerations and layout, Course 475 on manufacturing, Course 476 on assembly and testing including quality assurance, and Course 477 on production including QA and screening.

Prerequisites Students should have completed TTi's Course No. 104-3, “Electronics for Non-Electronic Engineers” or the equivalent. This course is aimed toward individuals actively involved in related technical fields. An understanding of basic electrical theory is required.

Text Each student will receive a course workbook, including most of the viewgraphs used in the course presentation.

Course Hours, Certificate and CEUs Open courses meet seven hours per day. Upcoming presentation dates can be found on our current open course schedule. Class hours/days for on-site courses can vary from 14-35 hours over 2-5 days as requested by our clients. Upon successful course completion, each participant receives a certificate of completion and one Continuing Education Unit (CEU) for every ten class hours.
