Why design review catches errors before fabrication in PCB Design - Dashboard Impact

Dashboard Mode - Why design review catches errors before fabrication

Goal

Understand how design reviews help catch errors before PCB fabrication to save time and cost.

Sample Data: PCB Design Errors and Costs

Design Stage	Errors Found	Cost per Error ($)	Total Cost ($)
Design Review	15	50	750
Fabrication	5	500	2500
Assembly	3	1000	3000
Testing	2	1500	3000
Field	1	5000	5000

Dashboard Components

• KPI Card: Total Errors Found in Design Review = 15
• KPI Card: Total Cost of Errors Found in Design Review = $750
• Bar Chart: Errors Found by Stage
  Formula: Use the 'Errors Found' column from the sample data
  Shows number of errors found at each stage
• Bar Chart: Cost per Error by Stage
  Formula: Use the 'Cost per Error ($)' column
  Shows how costly each error is depending on stage
• Stacked Bar Chart: Total Cost by Stage
  Formula: Use 'Total Cost ($)' column
  Shows total cost impact of errors at each stage
• Table: Detailed Error Costs by Stage
  Shows all columns from sample data for detailed view

Interactivity

A filter for Design Stage lets users select one or multiple stages.

When a stage is selected, all charts and KPIs update to show data only for that stage.

This helps focus on specific stages to see error counts and costs clearly.

Self Check

Add a filter for Design Stage = Fabrication. Which components update?

• KPI cards update to show errors and cost for Fabrication only (Errors = 5, Cost = $2500).
• Bar charts update to show only Fabrication data.
• Table filters to show only Fabrication row.

Key Result

Dashboard shows how design reviews catch more errors early at lower cost compared to later stages.
