1. What is a PCB Panel Array Calculator?

Definition: This calculator determines how many PCB panels can fit in a given total area based on individual panel dimensions.

Purpose: It helps electronics manufacturers and PCB designers optimize panel utilization during production.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Panels — Number of PCB panels that fit
• Total Area — Available manufacturing area (m²)
• Panel Area — Area of one PCB panel (m²)

Explanation: The total available area is divided by the area of one panel to determine how many panels can fit.

3. Importance of PCB Panel Calculation

Details: Accurate panel counting maximizes production efficiency, reduces material waste, and helps in cost estimation for PCB manufacturing.

4. Using the Calculator

Tips: Enter the total available area in m² and the area of one PCB panel in m². All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Should I account for spacing between panels?
A: Yes, either include spacing in your panel area measurement or reduce the total available area accordingly.

Q2: What's a typical panel size?
A: Common panel sizes are 457×610 mm (18×24 in) or 508×508 mm (20×20 in), but this varies by manufacturer.

Q3: How do I calculate panel area for irregular shapes?
A: For non-rectangular PCBs, use the maximum length × width or CAD software to determine exact area.

Q4: Does this account for panel utilization efficiency?
A: No, this gives theoretical maximum. Actual yield may be lower due to array arrangement constraints.

Q5: Should I round up or down the result?
A: Typically round down as partial panels aren't usable. Some designs may allow for partial panels.
