This knowledge includes details concerning printed circuit board materials, compo- nents, manufacturing processes, allowances, and limitations. The final product should have high producibility, reliability, and yield. This should all be confirmed by quality assurance and compliance. The Printed Circuit Engineering Association is structured for these challenges." The PCEA's Objectives The PCEA's objectives include: 1. Stimulating communication among and between printed circuit designers and others in related engineering disciplines. 2. Disseminating information regarding current activities and new developments in design technology via newsletters. 3. Maintaining a communications link between standards bodies related to printed circuit engineering and manufac- turing. Coordination includes, but is not limited to, the activities of government, industry, trade associations, and special interest groups. 4. Coordinating the compilation of design standardization issues in printed circuit fabrication and assembly with related design technologies. 5. Encouraging and coordinating the com- pilation of design information, including equipment, equipment capability (tools and technologies), and related information. 6. Promoting the necessity of early collabo- ration between engineering, fabrication, assembly, test, and field service. 7. Assisting in the participation of suppliers and OEMs in chapter programs. Steph thanked the audience and our sponsors before Rick Hartley was introduced, including instructions for submitting questions and how to participate in online polling throughout the webinar. Rick Hartley's Webinar Presentation I've been to many p re s e n t a t i o n s by Rick Hartley. Over t h e y e a r s , I ' v e attended multi-hour presentations, half- day presentations, a n d f u l l - d ay p re - sentations. Regard- less of the length of the presentation or the venue, I always enjoy the points Rick makes and the way he makes them. Hartley's emphasis on subject matter runs in a scale of magnitude from simple and personal to flat-out, in-your-face tangible. The one-hour webinar hosted by the PCEA featured Rick's topic, "Power Distribution Tips to Control SI, EMI, and Noise," did not dis- appoint. Rick is a master of making strikingly good points while explaining anything related to electronic performance on PCBs. I hope that all of our readers had the time to tune in. In case you didn't, here are a few excerpts from the presentation. Regarding energy in a PCB, Rick said, "Energy in a circuit is not in the voltage or the current. Energy is in the electric and magnetic fields." He continued, "Energy does not travel in the copper elements, such as traces and planes. Energy travels in the space between these cop- per elements." Rick went on to discuss many tips for SI and EMI control. He emphasized the importance of keeping inductance low and offered a few con- siderations for placement of vias in relationship to the positive and negative ends of a decou- pling capacitor. When designing for high-speed signal integrity, Rick explained the "mounted inductance" of capacitors. He showed how to lower inductance by adding a pair of vias to each end of the caps and explained the best Rick Hartley
