Common PCB design mistakes - Dashboard Guide

Dashboard Mode - Common PCB design mistakes

Goal

Understand the most frequent mistakes in PCB design and their impact on production and performance.

Sample Data: Common PCB Design Mistakes

Mistake	Frequency (%)	Impact Level	Cost Impact ($)	Detection Stage
Incorrect trace width	25	High	1500	Manufacturing
Insufficient clearance	20	High	1800	Testing
Wrong component placement	15	Medium	900	Assembly
Missing vias	10	Medium	700	Manufacturing
Improper grounding	12	High	1600	Testing
Silkscreen errors	8	Low	300	Assembly
Thermal issues	10	High	1400	Testing

Dashboard Components

• KPI Card: Total Cost Impact
  Formula: SUM of Cost Impact ($) = 1500+1800+900+700+1600+300+1400 = 8200
• Bar Chart: Frequency of Mistakes (%)
  Shows each mistake's frequency as bars for easy comparison.
• Pie Chart: Impact Level Distribution
  Shows percentage of mistakes by impact level (High, Medium, Low).
• Table: Detailed Mistakes Data
  Shows all columns from sample data for reference.

Interactivity

Filter by Detection Stage (Manufacturing, Testing, Assembly):

• Updates Bar Chart to show frequencies only for selected stage.
• Updates Pie Chart to reflect impact levels for filtered data.
• Updates Table to show only rows matching the selected stage.
• KPI Card updates total cost impact for filtered mistakes.

Self Check

If you add a filter for Detection Stage = Testing, which components update and what changes occur?

• KPI Card: Total Cost Impact updates to 1800 + 1600 + 1400 = 4800
• Bar Chart: Shows frequencies for Insufficient clearance (20%), Improper grounding (12%), Thermal issues (10%) only.
• Pie Chart: Reflects impact levels for these three mistakes (High impact mostly).
• Table: Displays only rows where Detection Stage is Testing.

Key Result

Dashboard shows common PCB design mistakes with their frequency, impact, cost, and detection stage, enabling focused quality improvements.
