Thermal spoke connections in PCB Design - Dashboard Guide

Dashboard Mode - Thermal spoke connections

Goal

Understand how thermal spoke connections affect heat dissipation in PCB designs by analyzing thermal resistance and temperature data.

Sample Data

Spoke Count	Spoke Width (mm)	Thermal Resistance (°C/W)	Max Temperature (°C)	Heat Dissipation (W)
4	0.5	15	85	2
6	0.5	12	78	2
8	0.5	10	75	2
6	1.0	9	72	2
8	1.0	7	68	2
10	1.0	6	65	2

Dashboard Components

• KPI Card: Average Thermal Resistance
  Formula: AVERAGE([Thermal Resistance (°C/W)])
  Result: 9.83 °C/W
• KPI Card: Minimum Max Temperature
  Formula: MIN([Max Temperature (°C)])
  Result: 65 °C
• Bar Chart: Thermal Resistance by Spoke Count and Width
  Description: Shows how thermal resistance decreases as spoke count and width increase.
  X-axis: Spoke Count
  Y-axis: Thermal Resistance (°C/W)
  Series: Spoke Width (0.5 mm, 1.0 mm)
• Line Chart: Max Temperature vs Spoke Count
  Description: Displays max temperature trend for different spoke widths.
  X-axis: Spoke Count
  Y-axis: Max Temperature (°C)
  Lines: Separate lines for each Spoke Width
• Data Table: Detailed Thermal Data
  Shows all columns from sample data for reference.

Interactivity

Filter by Spoke Width: Selecting a spoke width (0.5 mm or 1.0 mm) updates the bar chart, line chart, and data table to show only data for that width. The KPI cards recalculate averages and minimums based on the filtered data.

Filter by Spoke Count: Selecting a specific spoke count filters the charts and table to that count, updating KPIs accordingly.

Self Check

If you add a filter for Spoke Width = 1.0 mm, which components update?

• Bar Chart updates to show thermal resistance only for 1.0 mm width.
• Line Chart updates to show max temperature trend only for 1.0 mm width.
• Data Table filters to rows with 1.0 mm width.
• KPI Cards recalculate average thermal resistance and minimum max temperature for 1.0 mm width data.

Key Result

Dashboard shows how thermal spoke count and width affect thermal resistance and max temperature in PCB designs.
