When sourcing electronics manufacturing services, a PCBA quotation can often look complex. What exactly are you paying for? At Fully Hong, we believe in 100% transparency. In this guide and the accompanying video, Cosin Li breaks down every cost item on a PCBA quote, ensuring you understand where every penny of your budget is invested.

1. Electronic Component Cost (BOM)

The first and usually largest part of the quote is the component cost. This covers all the active and passive parts listed in your Bill of Materials (BOM).

• Quality Assurance: We only use qualified components.

• Incoming Inspection: Every batch undergoes a strict IQC (Incoming Quality Control) process before it reaches the production line.

2. PCB Bare Board Manufacturing

This is the cost of producing the empty circuit boards. It’s not just about the material; it also includes:

• Standard board fabrication (FR4, Aluminum, etc.)

• Electrical testing (E-test) to ensure 100% connectivity before assembly starts.

3. Assembly Processing Fees

This fee covers the labor and machine time involved in the full production cycle:

• SMT & DIP Soldering: High-speed placement and wave soldering.

• Cleaning & Inspection: Removing flux residues and visual/AOI inspection.

• Function Testing: Ensuring the assembled board works exactly as designed.

4. One-Time Tooling & Setup Charges

New projects often involve "One-Time" fees. Once paid, these are usually waived for repeat orders (unless the design changes).

• SMT Stencil Charge: A custom laser-cut stencil for precise solder paste printing.

• Fixture Fee: Customized reflow carriers, coating jigs, and testing fixtures to ensure stable mass production.

• SMT Line Opening Fee: Covers machine setup, program debugging, and the critical First Article Inspection (FAI).

5. Understanding Production Lead Times

Managing expectations on delivery is crucial for your product launch. At Fully Hong, our typical schedule is:

• Material Preparation: 1-2 weeks (Components + Bare PCBs).

• Mass Production & Assembly: After materials arrive, the final assembly takes place.

• Total Delivery: Generally 3 to 4 weeks for a complete turnkey project.

• Note: Lead times may vary if the BOM contains long-lead-time (non-cycle) components.

Conclusion

Every cost on a Fully Hong quotation corresponds directly to a value-added step in our production process. Our goal is to provide stable quality and professional service that justifies your investment.
