Learn about EMI control with Rick Hartley

EMI occurs when a physical structure resonates, causing radiation of electromagnetic fields from the structure, at one or more frequencies. This usually results from improper design of the PC board(s), or the enclosure, or the cabling, and is typically NOT from an issue in the schematic.

Many engineers design PC boards and their surrounding structures, hoping to NOT fail EMI testing, but knowing they likely will. With an understanding of proper PC board, enclosure and cabling design, failing compliance testing is very avoidable. The key to success is knowing how to design these structures to properly control and contain the electric and magnetic fields.

The knowledge gained from this two-day seminar WILL reduce product develop time and cost and WILL vastly improve product performance.

Items discussed are:

  • Energy movement in PC boards and how to control it
  • Driving factors behind frequency in digital and analog circuits
  • Common grounding problems that lead to EMI
  • Improper use of planes in a printed circuit board
  • Proper design and termination of transmission lines
  • Routing techniques that cause EMI and how to avoid them
  • Why some commonly used PCB design techniques cause EMI
  • Component placement to prevent EMI
  • Cross talk in single-ended lines and differential lines
  • Proper setup and routing of differential Pairs
  • Impact of IC package design on EMI
  • Problems caused by poor connector pin assignment
  • Problems caused by improper I/O connector location
  • PDN design and decoupling for low, medium and high-layer PCBs
  • Proper PCB layout of switch mode power supplies
  • Ground planes- to split or NOT to split… that is the question
  • Board stack-ups that cause EMI and those that resolve noise and EMI
  • Problems with LCD displays
  • Setup of the I/O structure to prevent EMI
  • Proper shielding of I/O cables
  • Proper chassis design to prevent EMI

 

This seminar is intended for PC board design engineers, electronic engineers and system engineers, as well as technicians and managers interested in EMI control at the PC board, enclosure and I/O cable levels.
