Millions of dollars’ worth of PWBs are scrapped each year due to tolerance errors in the final product. A good majority of these errors are due to incorrect tolerancing of holes, edges and other board features. This seminar will explain how GD&T can help you avoid high scrap rates and reduce overall cost due to improper dimensional tolerances. It will show how to apply GD&T to printed wiring boards without all the confusion found in complex mechanical objects such as gear trains and castings. The principles discussed follow the ASME Y14.5 standard, as well as IPC-2615, Printed Board Dimensions and Tolerances. Attendees will learn GD&T principles for printed wiring boards, appropriate symbology for drawings, and bilateral vs. geometric dimensioning.
