EMI Bites: Why Components Placement Matters for EMC
A common PCB design mistake?
Placing components like the crystal oscillators too far from the pins they feed.
Crystal clock signals, with sharp edges, carry high-energy harmonics.
When traces are long, these harmonics can couple to nearby signals or the power net, spreading interference across or beyond the board, causing EMI issues.
The solution: position crystals as close as possible to their pins to shorten traces and minimize coupling risks.
Apply this to enhance EMC performance.
