Four-layer stack-up design in PCB Design - Dashboard Guide

Dashboard Mode - Four-layer stack-up design

Goal

Understand the cost, signal integrity, and manufacturing time impact of different four-layer PCB stack-up designs.

Sample Data

Stack-up Name	Layer 1 (Top)	Layer 2	Layer 3	Layer 4 (Bottom)	Cost ($)	Signal Integrity Score (1-10)	Manufacturing Time (days)
Standard	Signal	Ground Plane	Power Plane	Signal	120	8	7
High-Speed	Signal	Ground Plane	Ground Plane	Signal	150	10	9
Cost-Optimized	Signal	Signal	Power Plane	Signal	90	6	5
Balanced	Signal	Ground Plane	Power Plane	Signal	110	7	6
Power-Focused	Power Plane	Ground Plane	Power Plane	Signal	130	7	8

Dashboard Components

• KPI Card: Average Cost
  Formula: Average of Cost column
  Result: (120+150+90+110+130)/5 = 120
• KPI Card: Highest Signal Integrity
  Formula: MAX of Signal Integrity Score
  Result: 10 (High-Speed stack-up)
• Bar Chart: Manufacturing Time by Stack-up
  X-axis: Stack-up Name
  Y-axis: Manufacturing Time (days)
  Shows how long each design takes to manufacture
• Table: Stack-up Details
  Shows all columns from sample data for detailed comparison
• Line Chart: Cost vs Signal Integrity
  X-axis: Cost ($)
  Y-axis: Signal Integrity Score
  Shows trade-off between cost and signal quality

Interactivity

A filter dropdown lets you select one or more stack-up designs by name.

When you select stack-ups, all components update to show only the selected designs:

• KPI cards recalculate averages and max for selected designs.
• Bar chart shows manufacturing times for selected stack-ups.
• Line chart updates cost vs signal integrity points.
• Table filters to show only selected stack-ups.

Self Check

If you add a filter to show only the 'Cost-Optimized' and 'Balanced' stack-ups, which components update and what are their new values?

• KPI Average Cost: (90 + 110) / 2 = 100
• KPI Highest Signal Integrity: MAX(6,7) = 7
• Bar Chart: Manufacturing Time shows 5 and 6 days
• Line Chart: Points at (90,6) and (110,7)
• Table: Shows only rows for 'Cost-Optimized' and 'Balanced'

Key Result

Dashboard compares cost, signal integrity, and manufacturing time across four-layer PCB stack-up designs.
