SMT Production Cost Calculation: A Framework for Profitability

Accurately calculating your SMT Production Cost is essential for quoting, profitability analysis, and identifying areas for efficiency gains. Here’s a breakdown of the key cost components.

The Core Cost Formula

Total Cost per Board = (Equipment Cost + Labor Cost + Material Cost + Overhead Cost) / Number of Boards

1. Equipment (Capital) Cost

• Depreciation: Spread the purchase price of printers, placers, ovens, etc., over their useful life (e.g., 5-7 years).

• Maintenance & Repairs: Annual service contracts and spare parts.

• Utilities: Electricity and compressed air consumption.

2. Labor Cost

• Direct Labor: Wages for machine operators and line technicians.

• Indirect Labor: Engineering, programming, and management support.

3. Material Cost (Bill of Materials - BOM)

• PCB Cost

• Component Cost

• Consumables Cost: Solder paste, stencils, glue, nozzles.

4. Overhead Cost

• Factory Rent/Utilities

• Quality Control & Testing

• Administrative Expenses

Key Metrics for Efficiency

• Overall Equipment Effectiveness (OEE): A low OEE increases your effective cost per board.

• First-Pass Yield (FPY): Rework and scrap directly inflate material and labor costs.

Lowering your cost per board starts with efficient equipment. Discover high-OEE machines at SMTFullLine.com to optimize your bottom line.
