1. What is PCB Panel Array Calculation?

PCB Panel Array calculation determines how many individual printed circuit boards can fit efficiently on a manufacturing panel. This optimization helps maximize production efficiency and minimize material waste in PCB fabrication.

2. How Does the Calculator Work?

The calculator uses the PCB Panel Array formula:

\[ Panels = \left( \frac{\text{Board Length}}{\text{Panel Length}} \right) \times \left( \frac{\text{Board Width}}{\text{Panel Width}} \right) \]

Where:

\( Board Length \) — Length of individual PCB board (mm)
\( Panel Length \) — Length of manufacturing panel (mm)
\( Board Width \) — Width of individual PCB board (mm)
\( Panel Width \) — Width of manufacturing panel (mm)

Explanation: The calculation determines the maximum number of PCBs that can be arranged in a rectangular grid pattern on the manufacturing panel.

3. Importance of Panel Optimization

Details: Proper panel optimization reduces material waste, lowers production costs, increases manufacturing throughput, and improves overall production efficiency in PCB fabrication.

4. Using the Calculator

Tips: Enter all dimensions in millimeters. Ensure board dimensions are smaller than panel dimensions. Consider adding spacing between boards for routing and handling in actual production.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between board and panel dimensions?
A: Board dimensions refer to the individual PCB size, while panel dimensions refer to the larger manufacturing substrate that holds multiple boards.

Q2: Why are the results sometimes fractional?
A: The calculation shows theoretical maximum. In practice, you'll use the integer portion, as you cannot have fractional PCBs on a panel.

Q3: Should I account for spacing between boards?
A: Yes, in actual production, you should include routing channels and clearance between boards, which will reduce the effective panel area.

Q4: What are common panel sizes in PCB manufacturing?
A: Common panel sizes include 18×24 inches (457×610 mm), 21×24 inches (533×610 mm), and various metric sizes like 300×400 mm or 400×500 mm.

Q5: Can I use this for irregular board shapes?
A: This calculator assumes rectangular boards. For irregular shapes, the actual panel utilization may be lower due to wasted space.
