    Factor

    SMT (Surface Mount Technology)

    DIP (Dual In-line Package)

    Equipment Costs

    Significant upfront investment in machines costing tens to hundreds of thousands of dollars.

    Minimal equipment needed, lower initial costs.

    Labor and Production Costs

    Lower long-term labor costs due to automation, but higher per-unit costs for small batches.

    Higher labor costs for manual assembly, but lower setup fees.

    Productivity

    Automated lines produce thousands of PCBs daily, ideal for scaling production.

    Manual processes limit speed, suitable for small batches.

    Tip: Choose commercial secure pcba assembly secure​ when you need flexibility, strong security, and reliable quality for commercial, defense, and surveillance projects.
