Why libraries ensure correct component mapping in PCB Design - Dashboard Impact

Dashboard Mode - Why libraries ensure correct component mapping

Business Question

How do libraries help ensure that components in a PCB design are correctly mapped to their physical parts, reducing errors and improving assembly accuracy?

Sample Data: Component Mapping Table

Component ID	Library Part Name	Footprint	Pin Count	Mapped Correctly
R1	Resistor_1k	0603	2	Yes
C1	Capacitor_10uF	0805	2	Yes
U1	Microcontroller_XYZ	QFP-64	64	Yes
LED1	LED_Red	1206	2	No
J1	Connector_USB	USB-B	4	Yes
Q1	Transistor_NPN	TO-92	3	Yes
L1	Inductor_10uH	0805	2	Yes

Dashboard Components

• KPI Card: Total Components - COUNTROWS('ComponentMapping') = 7
• KPI Card: Correctly Mapped Components - CALCULATE(COUNTROWS('ComponentMapping'), 'ComponentMapping'[Mapped Correctly] = "Yes") = 6
• KPI Card: Incorrectly Mapped Components - CALCULATE(COUNTROWS('ComponentMapping'), 'ComponentMapping'[Mapped Correctly] = "No") = 1
• Bar Chart: Components by Footprint
  Formula: SUMMARIZE('ComponentMapping', 'ComponentMapping'[Footprint], "Count", COUNT('ComponentMapping'[Component ID]))
  Shows how many components use each footprint type.
• Table: List of Incorrectly Mapped Components
  Filter: FILTER('ComponentMapping', 'ComponentMapping'[Mapped Correctly] = "No")
  Shows details of components with mapping issues.

Layout

+----------------------+----------------------+----------------------+
| Total Components (7) | Correctly Mapped (6) | Incorrectly Mapped (1) |
+----------------------+----------------------+----------------------+
|                      Bar Chart: Components by Footprint                      |
|                              (0603, 0805, QFP-64, etc.)                      |
+-----------------------------------------------------------------------------+
|                      Table: Incorrectly Mapped Components                    |
|                              (LED1 - LED_Red - 1206)                         |
+-----------------------------------------------------------------------------+

Interactivity

Applying a filter on the "Mapped Correctly" field updates the KPI cards, bar chart, and table. For example, selecting "No" in the filter shows only incorrectly mapped components in the table and updates KPIs accordingly. Selecting a footprint type filters the bar chart and table to show components with that footprint.

Self Check

If you add a filter to show only components with Mapped Correctly = No, which components appear in the table and how do the KPI cards update?

Answer: The table shows only LED1 with incorrect mapping. The KPI cards update to Total Components = 1, Correctly Mapped = 0, Incorrectly Mapped = 1.

Key Result

Dashboard shows how libraries ensure correct component mapping by tracking mapped components, footprint usage, and highlighting errors.
