EMI reduction techniques in PCB Design - Dashboard Guide

Dashboard Mode - EMI reduction techniques

Goal

Understand which EMI reduction techniques are most effective in reducing electromagnetic interference in PCB designs.

Sample Data

Technique	Effectiveness Score (1-10)	Cost ($)	Implementation Time (hours)	Complexity Level
Ground Plane	9	50	2	Low
Shielding	8	120	4	Medium
Filtering	7	80	3	Medium
Twisted Pair Routing	6	30	1	Low
Component Placement	7	40	2	Low
Decoupling Capacitors	8	60	2	Low
Ferrite Beads	5	25	1	Low

Dashboard Components

• KPI Card: Average Effectiveness Score
  Formula: Average of Effectiveness Score column
  Result: 7.14
• KPI Card: Total Cost
  Formula: Sum of Cost column
  Result: 405
• Bar Chart: Effectiveness Score by Technique
  X-axis: Technique
  Y-axis: Effectiveness Score
  Shows which techniques have higher effectiveness.
• Pie Chart: Cost Distribution by Technique
  Shows how cost is spread across techniques.
• Table: Techniques Sorted by Implementation Time
  Sorted ascending by Implementation Time to see quickest methods first.

Interactivity

A filter for Complexity Level allows users to select Low, Medium, or all techniques. When filtered, all components update to show data only for selected complexity levels. For example, selecting 'Low' updates KPIs, charts, and table to reflect only low complexity techniques.

Self Check

If you add a filter for Complexity Level = Low, which components update and what changes occur?

• Average Effectiveness Score KPI updates to average of Low complexity techniques (Ground Plane, Twisted Pair Routing, Component Placement, Decoupling Capacitors, Ferrite Beads).
• Total Cost KPI updates to sum of costs for Low complexity techniques.
• Bar Chart shows only Low complexity techniques with their effectiveness scores.
• Pie Chart updates to show cost distribution only for Low complexity techniques.
• Table shows only Low complexity techniques sorted by implementation time.

Key Result

Dashboard shows effectiveness, cost, and implementation time of EMI reduction techniques with filtering by complexity.
