A PCB Calculator is an online tool that computes essential parameters for PCB design and production. It calculates trace width, impedance, via current capacity, and costs, ensuring your PCB meets electrical, thermal, and manufacturing standards (e.g., IPC-2152, IPC-2221). Whether you’re prototyping a hobby project or ordering PCBs online in India, our calculator provides accurate, real-time results to save time and reduce errors.

Use our integrated PCB Calculator and order form to design and quote your PCB in one place. Input your specifications, get instant cost estimates for different lead times, and submit your order seamlessly.

Our PCB Calculator goes beyond cost estimation, offering technical tools to optimize your design:

Trace Width Calculator

• Computes minimum trace width based on current, copper weight, and temperature rise (IPC-2152).
• Ideal for power supplies, LED drivers, and high-current circuits.
• Example: For 3A on 1 oz copper (external layer, 10°C rise), trace width is ~1.2 mm.

Impedance Calculator

• Calculates trace impedance for microstrip or stripline (e.g., 50Ω for RF, 90Ω for USB).
• Ensures signal integrity for high-speed circuits like HDMI or USB.
• Supports FR-4 and other substrates with customizable dielectric constants.

Via Current Calculator

• Estimates via current capacity based on diameter and plating thickness.
• Perfect for multilayer PCBs requiring robust power delivery.
• Example: A 0.4 mm via with 25 µm plating handles ~3A safely.

Thermal & Power Loss Calculator

• Estimates heat dissipation and power loss to prevent overheating.
• Recommends thermal management solutions, like heat sinks, for high-current designs.

Additional Calculators

• Copper Thickness & Resistance Computes trace resistance to manage voltage drops.
• Component Spacing Ensures IPC-compliant spacing to avoid crosstalk and EMI.
• Gerber File Validation Checks for errors before manufacturing.

PCB Price in India: Key Factors

PCB prices in India vary by location, materials, and order size. For example, the PCB price in Ahmedabad may differ from Bangalore or Mumbai due to local manufacturing hubs. Our calculator provides real-time cost estimates, factoring in:

• Board size and layer count
• Material (FR-4, Polyimide, Rogers)
• Surface finish and solder mask
• Lead time (1 to 10 days)

Secondary factors like soldering costs or component availability are also considered, ensuring you get a clear picture for your online PCB order in India.

Best Practices for PCB Design and Ordering

• Start with a Prototype: Test a small batch to identify design flaws early.
• Check Trace Width Early: Ensure current capacity to avoid overheating.
• Compare Materials: Balance cost and performance with FR-4 or Rogers.
• Optimize Board Size: Smaller boards reduce material and manufacturing costs.
• Plan for Thermal Management: Calculate heat dissipation for reliability.
• Test Surface Finishes: Compare HASL, ENIG, or OSP for durability and cost.
• Leverage Online Ordering: Use our platform for competitive pricing and fast delivery.
