A Step-by-Step Guide from Poly Electronics

As global supply chain dynamics continue to shift, many companies are reevaluating their reliance on overseas suppliers—particularly in the area of printed circuit board assembly (PCBA). Common concerns such as lead time variability, rising tariffs, IP protection, and logistics disruptions are prompting organizations to bring assembly operations closer to home.

At Poly Electronics, we specialize in helping companies make this transition efficiently and confidently. Whether you’re preparing for your first domestic build or looking to replace an offshore supplier, our team ensures that the process is streamlined and supported every step of the way.

Below is a clear roadmap for transferring your PCB assembly from China to a trusted U.S.-based partner like Poly Electronics.

Step 1: Prepare a Complete Manufacturing Package

The foundation of a smooth transition begins with documentation. Providing a comprehensive and well-organized manufacturing package reduces delays and enables a more accurate quote and build process.

Essential Files Include:

• Gerber Files (all layers and drill data)
• Bill of Materials (BOM) with part numbers, manufacturers, designators, and quantities
• Pick-and-Place File (Centroid)
• Assembly Drawings with notes on polarity, special placements, or no-stuff components
• Testing Requirements or procedures (if applicable)
• 3D CAD Files (optional but recommended for mechanical verification)
• Approved Vendor List (AVL) (if preferred suppliers are already established)

How We Help: At Poly Electronics, our engineering team will review your files for completeness and notify you of any missing elements or potential issues before the quoting stage begins.

Step 2: Request a Quote from Our Team

Once your documentation is ready, we invite you to submit your project by contacting us directly at info@polyelectronics.us. Our quoting process is fast, transparent, and handled by real engineers—not automated systems.

We’ll assess your files thoroughly and return a detailed quote, typically within 24–72 hours, including lead time, material availability, and any immediate recommendations.

Step 3: Onboarding and Engineering Review

Transitioning from an overseas supplier often presents opportunities to improve quality, reduce complexity, or address sourcing issues. As part of our onboarding process, we offer:

• Design for Manufacturability (DFM) Reviews
• Component Sourcing Audits
• Process Compatibility Checks (e.g., for special finishes, solder types, or unique components)

Our goal is to help you avoid delays and optimize for domestic production—without requiring major design changes.

Step 4: Strategic Component Sourcing

One of the most common challenges when transitioning from China is the difference in component sourcing channels. Components that were readily available through your offshore supplier may now require new sourcing strategies or substitutions.

Poly Electronics provides:

• Access to a broad network of U.S. distributors
• Alternate part recommendations for hard-to-source or obsolete components
• Full or partial turnkey solutions (including consigned kits, if preferred)

By aligning your BOM with domestic availability, we reduce risk and help keep production timelines intact.

Step 5: Prototype and First Article Validation

We strongly recommend starting with a pilot run or first article build to validate assembly quality, ensure alignment with design intent, and identify any adjustments needed prior to full-scale production.

At this stage, Poly Electronics provides:

• Thorough inspection reports
• Photographic documentation
• Optional customer-supplied acceptance criteria

Once approved, the transition to volume production is immediate and seamless.

Step 6: Full Production and Ongoing Support

With the prototype phase complete, we move forward with full production, tailored to your volume and scheduling requirements. Poly Electronics offers:

• Consistent lead times
• Quality assurance at every stage
• Real-time communication and project updates
• Scalable production capabilities

We act as an extension of your engineering and operations team—ensuring that every build meets your specifications, schedule, and quality standards.
