About PCB Copper Weight Calculator:
This calculator helps determine the total copper weight in PCB designs based on board dimensions and layer configuration.
Formula Used:
- Area (m²) = Length × Width
- Copper Weight per Layer = Area × Copper Weight × Coverage
- Total Weight = Weight per Layer × Number of Layers
- Where:
- 1 oz/ft² = 305.15 g/m²
- Coverage = Percentage of area covered by copper
- Copper density = 8.96 g/cm³
PCB Design Guide: Calculating Copper Weight for Cost-Effective PCB Manufacturing
In professional PCB design and PCB manufacturing, accurate copper weight calculation is crucial for cost estimation and PCB fabrication planning. This PCB Copper Weight Calculator streamlines the PCB layout process by helping engineers determine precise material requirements for multilayer PCB design.
How to Use the PCB Copper Weight Calculator:
Follow these steps for PCB prototyping and PCB assembly planning:
- Enter board dimensions (length and width in mm)
- Select copper weight (commonly 1 oz/ft² for standard PCB fabrication)
- Choose number of layers for multilayer PCB manufacturing
- Specify copper coverage percentage (typically 80% for standard designs)
Example PCB Design Case:
Consider a 4-layer PCB design for a power supply:
- Board dimensions: 100mm × 80mm
- Copper weight: 2 oz/ft² for power planes
- Layers: 4 (power, ground, and signal layers)
- Coverage: 85% for optimal power distribution
