Layer stack configuration in PCB Design - Dashboard Guide

Dashboard Mode - Layer stack configuration

Goal

Understand the layer stack configuration of a PCB to analyze signal integrity and manufacturing complexity.

Sample Data: PCB Layer Stack

Layer Number	Layer Name	Material	Thickness (mil)	Type
1	Top Signal	Copper	1.4	Signal
2	Prepreg	FR4	3.5	Dielectric
3	Inner Signal 1	Copper	1.4	Signal
4	Core	FR4	6.2	Dielectric
5	Inner Signal 2	Copper	1.4	Signal
6	Prepreg	FR4	3.5	Dielectric
7	Bottom Signal	Copper	1.4	Signal

Dashboard Components

• Total Layers: KPI card showing count of layers.
  Formula: COUNT([Layer Number]) = 7
• Total Signal Layers: KPI card showing count of signal layers.
  Formula: COUNTIF([Type], "Signal") = 4
• Total Dielectric Thickness: KPI card showing sum of thickness for dielectric layers.
  Formula: SUMIF([Type], "Dielectric", [Thickness (mil)]) = 10.7 mil
• Layer Thickness Bar Chart: Bar chart showing thickness by layer name.
  X-axis: Layer Name, Y-axis: Thickness (mil)
• Layer Type Pie Chart: Pie chart showing proportion of Signal vs Dielectric layers.
  Signal: 4 layers, Dielectric: 3 layers
• Layer Details Table: Table listing all layers with their properties for detailed view.

Interactivity

Filter by Layer Type (Signal or Dielectric):

• Updates KPI cards to show counts and thickness only for selected type.
• Bar chart updates to show thickness of filtered layers.
• Pie chart updates to reflect filtered data proportion.
• Layer details table filters to show only selected layer types.

Self Check

If you add a filter for Layer Type = "Signal", which components update and what are their new values?

• Total Layers KPI updates to 4.
• Total Signal Layers KPI updates to 4.
• Total Dielectric Thickness KPI updates to 0 mil.
• Bar chart shows thickness for Top Signal, Inner Signal 1, Inner Signal 2, Bottom Signal layers only.
• Pie chart shows 100% Signal.
• Layer details table shows only signal layers.

Key Result

Dashboard showing PCB layer stack details including counts, thickness, and layer types with interactive filtering.
