Creating custom symbols in PCB Design - Dashboard Building Guide

Dashboard Mode - Creating custom symbols

Goal

Understand how to create custom symbols for PCB design to improve schematic clarity and reuse.

Sample Data

Symbol Name	Pin Count	Pin Names	Package Type	Description
OpAmp_1	5	IN+, IN-, VCC, VEE, OUT	SOIC-8	Operational Amplifier
Resistor_1	2	1, 2	0603	Fixed Resistor
Capacitor_1	2	1, 2	0805	Capacitor
LED_1	2	Anode, Cathode	LED-3mm	Light Emitting Diode
Microcontroller_1	32	VDD, VSS, GPIO1-GPIO30, RESET	QFP-32	Microcontroller Unit

Dashboard Components

• KPI Card: Total Symbols Created - Formula: COUNT(Symbol Name) Result: 5
• Table: Symbol Details - Shows all columns from sample data for reference.
• Bar Chart: Pin Count per Symbol - X-axis: Symbol Name, Y-axis: Pin Count
• Pie Chart: Distribution by Package Type - Shows percentage of symbols per package type

Dashboard Layout

+----------------------+-----------------------+
| Total Symbols Created | Pin Count per Symbol  |
|        (KPI)          |       (Bar Chart)      |
+----------------------+-----------------------+
|       Symbol Details Table                  |
|                                            |
+--------------------------------------------+
|        Distribution by Package Type (Pie)  |
+--------------------------------------------+

Interactivity

Filter by Package Type: Selecting a package type filters the Symbol Details Table and updates the Pin Count Bar Chart to show only symbols of that package. The KPI card updates to show the count of filtered symbols. The Pie Chart remains static as it shows overall distribution.

Self Check

If you add a filter for Package Type = '0603', which components update and what changes occur?

• KPI Card updates to show 1 symbol.
• Symbol Details Table shows only the Resistor_1 row.
• Pin Count Bar Chart shows only Resistor_1 with pin count 2.
• Pie Chart remains unchanged showing all package types.

Key Result

Dashboard shows custom PCB symbols with pin counts, package types, and symbol details for design clarity.
