Small PCBs: They are categorized into 2x2 to 4x4 inches, being the most cost-effective. If you go for them, you'll be spending around $5 to $20 per board, depending on complexity.
Medium-Sized PCBs: They are of moderate pricing from $10 to $30, depending on your specification type. You can easily get them in 4x4 to 6x6 inches.
Moreover, every quantity order (except bulk orders) has a set price per square inch. As a result, the price per unit will decrease the more units you order. Once you know how much things will cost, you can make a project budget and determine how much profit you need to include in your PCB assembly price. It will then be simple to choose the costs for each item your business produces.
Component Cost: Begin by determining the cost of individual components. For example, resistors ($0.1-$1), integrated circuits ($1-$10 per chip), connectors and switches ($0.10-$5 each). You can obtain this information from suppliers or distributors. Sum up the prices of all components required for the PCB assembly.
Labor Costs: Calculate labor costs based on the time required for assembly. This depends on the complexity of the design and the assembly method used. When you opt for SMT assembly, the labor cost would be $15-$30 per hour. Similarly, if you go for specialized or prototype assembly, labor costs will range from $20-$50 per hour. Moreover, skilled technicians may charge higher hourly rates.
Overhead Costs: Consider overhead costs, including rent for the assembly facility, utilities, maintenance, and equipment depreciation. These costs are typically spread across the total production volume and will charge you about 20% to 40% of the total cost.
Materials: Account for the cost of materials such as the PCB substrate, solder paste, and any specialized materials required for the assembly.
Testing and Inspection: Include the cost of testing and inspection equipment, labor, and necessary rework or repairs. The basic functional testing is $0.10-$2 per board.
Quality Assurance: Factor in the cost of adhering to industry standards or certifications, which may involve additional testing and documentation.
