PCB Manufacturing Process

Turnkey PCB Assembly Process

Getting familiar with the process can help you understand what to expect and how it works.

1. Design Review and File Preparation

Before production begins, we conduct Design for Manufacturing (DFM) checks to ensure the PCB is optimized for efficient and cost-effective assembly. We require essential design files, including Gerber, ODB++, BOM, NC drill, and pick-and-place files. A thorough design review helps detect manufacturability issues early, avoiding costly delays.

2. Component Sourcing and Procurement

We handle component sourcing by selecting parts based on the BOM, balancing cost, availability, and lead time. Standard components speed up production, while hard-to-find parts may extend timelines. Our trusted supplier network ensures quality parts at competitive prices, helping reduce procurement risks and costs.

3. Material Preparation

Before assembly, we inspect and verify all components and materials to prevent defects. This includes checking for damage, ensuring part compatibility, and verifying inventory levels. Proper preparation ensures smooth production, reduces rework, and enhances final PCB quality by eliminating material-related issues.

4. PCB Fabrication

Once materials are ready, we begin PCB fabrication, which includes layer stacking, etching, drilling, solder masking, and surface finishing. We also perform quality control checks throughout the process to detect structural or electrical defects. This step ensures the PCB meets design requirements before assembly.

5. Assembly (SMT & Through-Hole)

During assembly, we use Surface Mount Technology (SMT) for high-speed, automated component placement. Through-hole assembly is used for components requiring stronger mechanical bonds. Both methods involve soldering, quality inspections, and reflow processes to ensure secure connections and structural integrity.

6. Inspection and Testing

To maintain high standards, we conduct multiple inspection and testing methods, including AOI, X-ray, ICT, flying probe, and functional testing. These tests identify potential defects before shipment, ensuring reliability, electrical performance, and compliance with industry quality standards.

7. Programming

For PCBs requiring embedded software or firmware, we program microcontrollers, FPGAs, and other ICs to perform their intended functions. Common applications include smart devices, medical equipment, and industrial automation, ensuring seamless integration and device functionality.

8. Conformal Coating

To protect the PCB from moisture, dust, and extreme conditions, we apply a thin conformal coating after assembly. This enhances durability, reduces environmental damage, and extends the PCB’s operational lifespan, especially for harsh environments or mission-critical applications.

9. Final Inspection and Packaging

Before shipping, we perform a final quality check to ensure the PCB is defect-free, fully functional, and meets customer specifications. Boards are packaged in antistatic bags, vacuum-sealed, and moisture-protected to prevent damage in transit, ensuring safe and reliable delivery.

What is the Cost of Turnkey PCB Assembly?

The cost of turnkey PCB assembly varies significantly based on several factors. For a rough estimate, the cost of manufacturing a printed circuit prototype ranges from $10 to $50, depending on size, material, and production labor costs. Assembly costs per square inch can range from $0.02 to $0.05, influenced by necessary assembly labor, labor rates, assembly time, overhead manufacturing expenses, and board design complexity.

Benefits of Turnkey PCB Assembly

Streamlined Supply Chain Management

Only one vendor provides your turnkey services, meaning other suppliers won’t need to get involved in all or a portion of the project. As a result, all the processes are easier to coordinate and manage.

Cost Efficiency

Customers can save with turnkey PCB assembly by relying on cost-effective suppliers. They take advantage of bulk ordering, supply chains, and economies of scale — making them more cost-efficient.

Reduced Time-to-Market

The end product will land on the market much faster due to the faster manufacturing that results from fewer collaborations between vendors.

Quality Assurance

Meeting consistent quality standards occurs when one supplier takes care of the production process. This also involves regularly focusing on quality control.

Turnkey PCB Assembly FAQs

When should you use Turnkey PCB Assembly?

You will want to use turnkey PCB assembly under these conditions:

Complex Designs: Without turnkey services, projects could see a high demand for in-house resources. So they’re perfect for handling high-density interconnections, sophisticated component integration, and complex designs. All of these rely on expertise, resource optimization, quality assurance, cost efficiency, risk mitigation, and time management.

Volume Production: Turnkey services can make large manufacturing runs cost-effective by saving money. This happens because one provider deals with production.

Lack of In-House Capabilities: If a manufacturer doesn’t have the right resources or in-house capabilities for assembly, outsourcing becomes a good option.

Focus on Core Competencies: Handing over the assembly job to a different provider can allow the company to focus on its core competencies. This means using resources/time to develop products and expand.

Effective Communication – We provide a dedicated point of contact, clear project timelines, and real-time updates to enhance collaboration and efficiency.

What is the Typical Lead Time for a Turnkey PCB Assembly Project?

A turnkey PCB project can take between 1 and 15 days to assemble. Of course, that length depends on how many components the project needs.

What File Formats do I need to provide for Turnkey PCB Assembly?

You will need the BoM, centroid data, and Gerber or ODB++ design files.

Can you make changes to the Design after the Turnkey PCB Assembly Process has Begun?

It’s expensive and hard to modify the design after assembly has started. Those costs decrease if you discuss any changes early.
