Calculate Custom PCB Board Cost by Size
One of the most straightforward methods for calculating the cost of custom PCBs, especially for small batches and prototypes, is the area-based pricing approach. This technique allows PCB manufacturers to provide a cost estimate based on the physical dimensions of the board, offering a quick and convenient way to obtain custom PCB pricing.
- How Area-Based Pricing Works
In this pricing model, the PCB manufacturer determines a unit price per square centimeter (or inch) based on the number of layers and specific manufacturing processes required. Customers simply need to provide the board dimensions, and the total cost is calculated by multiplying the area by the predetermined unit price.
For example, if the manufacturer’s price for a 4-layer board is $0.05 per square centimeter, and your custom PCB measures 10cm x 15cm, the estimated cost would be:
Board Area = 10cm x 15cm = 150 sq.cm Custom PCB Cost = 150 sq.cm x $0.05/sq.cm = $7.50
- Ideal for Prototyping and Low Volumes
The area-based pricing approach is particularly well-suited for prototyping and low-volume custom PCB orders. It offers a straightforward and accessible way to obtain cost estimates quickly, without the need for detailed design specifications or a complex quoting process. - Advantages and Limitations Advantages:
