What is a printed circuit board in PCB Design - Dashboard Concepts

Dashboard Mode - What is a printed circuit board

Business Question

Understand what a printed circuit board (PCB) is and how it is used in electronics manufacturing.

Sample Data: PCB Components and Attributes

Component	Type	Quantity	Function	Layer Count
Resistor	Passive	50	Control current	2
Capacitor	Passive	30	Store energy	2
Microcontroller	Active	5	Process data	4
Connector	Interface	10	Connect devices	2
LED	Active	20	Indicate status	2

Dashboard Components

• KPI Card: Total Components = SUM of Quantity = 115
• KPI Card: Average Layer Count = AVERAGE of Layer Count = 2.4
• Bar Chart: Quantity by Component Type (Passive, Active, Interface)
• Table: Detailed list of components with their function and layer count

Dashboard Layout

+----------------------+----------------------+
|  Total Components     |  Average Layer Count  |
|       [115]          |         [2.4]          |
+----------------------+----------------------+
|                                          |
|          Bar Chart: Quantity by Type     |
|                                          |
+------------------------------------------+
|                                          |
|      Table: Component Details            |
|                                          |

Interactivity

Filter by Component Type (Passive, Active, Interface) updates the bar chart, KPI cards, and table to show only selected types.

Self Check

If you filter to show only "Active" components, what is the new total quantity and average layer count?

Answer: Total Quantity = 25 (5 Microcontrollers + 20 LEDs), Average Layer Count = 3 (average of 4 and 2)

Key Result

A dashboard explaining what a printed circuit board is by showing component quantities, types, and layer counts.
