Single-layer vs multi-layer PCB in PCB Design - Dashboard Approaches Compared

Dashboard Mode - Single-layer vs multi-layer PCB

Goal

Compare the key features and costs of single-layer and multi-layer PCBs to help decide which type suits a project best.

Sample Data

PCB Type	Layers	Cost per Unit ($)	Signal Integrity	Manufacturing Time (days)	Typical Use Case
Single-layer	1	5	Low	3	Simple circuits
Double-layer	2	10	Medium	5	Moderate complexity
Multi-layer (4 layers)	4	20	High	7	Complex circuits
Multi-layer (6 layers)	6	30	Very High	10	High-speed circuits
Multi-layer (8 layers)	8	40	Very High	12	Advanced applications

Dashboard Components

• KPI Card: Average Cost per Unit
  Formula: Average of 'Cost per Unit ($)' column
  Result: (5+10+20+30+40)/5 = 21
• KPI Card: Average Manufacturing Time
  Formula: Average of 'Manufacturing Time (days)' column
  Result: (3+5+7+10+12)/5 = 7.4 days
• Bar Chart: Cost per Unit by PCB Type
  X-axis: PCB Type
  Y-axis: Cost per Unit ($)
  Shows increasing cost with more layers
• Line Chart: Manufacturing Time by Number of Layers
  X-axis: Layers
  Y-axis: Manufacturing Time (days)
  Shows longer time for more layers
• Table: Detailed PCB Comparison
  Shows all columns from sample data for reference

Interactivity

A filter for 'PCB Type' allows selecting single-layer, double-layer, or multi-layer types. When a type is selected:

• KPI cards update to show averages only for the selected type(s).
• Bar and line charts update to display data for the selected type(s).
• The detailed table filters rows to match the selection.

This helps focus analysis on specific PCB types.

Self Check

If you add a filter to select only 'Single-layer' PCBs, which components update and what changes?

• KPI cards show cost = $5 and manufacturing time = 3 days.
• Bar chart shows only the single-layer cost bar.
• Line chart shows manufacturing time for 1 layer only.
• Table shows only the single-layer PCB row.

Key Result

Dashboard compares cost, manufacturing time, and features of single-layer vs multi-layer PCBs.
