Turning complex circuit board designs into reliable, high-quality products requires an efficient and detail-oriented process. Our step-by-step approach eliminates common manufacturing obstacles, ensuring smooth production, superior quality, and on-time delivery. Each stage is designed to tackle potential pain points, giving you confidence that your PCB assembly project will be handled with precision and expertise.
Every successful project starts with a strong foundation. Our engineers work closely with your team to review your design files, providing Design for Manufacturability (DFM) feedback. This early-stage consultation helps prevent costly revisions and optimizes your design for a seamless transition to production.
Component sourcing can be challenging, especially when balancing cost and lead times. Our experienced procurement team handles all aspects of materials procurement, ensuring that the best-quality components are used and that your project stays on schedule, even for complex printed circuit board designs.
We use state-of-the-art surface mount technology (SMT) and through-hole assembly techniques to build your circuit boards with the highest accuracy and consistency. Our advanced equipment and skilled technicians ensure precise placement of even the smallest components for a robust, reliable build.
Quality is our top priority. Each assembly goes through multiple inspection stages, including Automated Optical Inspection (AOI), X-ray testing, and comprehensive functional testing. This ensures every circuit board meets stringent standards and performs as expected.
Once testing is complete, your product is prepared for delivery. Whether you need full box builds, special packaging, or local delivery, our logistics team ensures that each project arrives on time and ready for deployment.

Full Reels Preferred: Whenever possible, provide full reels to minimize machine downtime and ensure uninterrupted production.
Cut Tape: If cut tape is necessary, it must be at least 5 inches long for proper feeder handling.
Machine Loss: Add 2% for all passive components to account for machine loss, and 4% for 0402 caps and resistors.
Loose Components: Loose parts must be hand-placed, which increases time and cost—please avoid whenever possible.
Labeling: Clearly label reels or trays with the customer part number and a complete component description, including value and part type.
IC Packaging: Integrated Circuits (ICs) should ideally be on tape and reel; however, if tubes are used, ensure all components face the same direction and the tube is properly labeled.
Boards must include fiducials, silkscreen reference markers, and adequate component clearance. Consider panelizing for smaller boards to maximize efficiency.

Fiducials: Boards and panels must include fiducials for accurate alignment during assembly.
Silkscreen: Ensure reference designators and polarity markers are visible on the silkscreen.
Component Clearance: Components should not be placed within 0.080 inches of the edge of the board to avoid damage.
Panelization: For boards smaller than 3x4 inches, consider panelizing. Ideal panel size is approximately 8x10 inches with a 0.25” border.
Double-Sided Boards: For double-sided assemblies, passive components should be placed on the bottom side when possible.
Submit Gerber files, a current BOM, and CAD data for machine programming. Include an audit sheet for any shortages, and consider providing a sample board.

Gerber Files: Gerber data is required to produce the stencil and ensure proper layout for panelized boards.
BOM (Bill of Materials): Provide an accurate BOM for the current build, including all parts and values, for assembly accuracy.
CAD Data: CAD data is required for machine programming and ensuring precise component placement.
Audit Sheet: Include an audit sheet listing all shortages and discrepancies in the provided parts to avoid delays in the assembly process.
Sample Board (Optional): Providing a sample board can greatly aid in the accurate assembly of your production run.
To guarantee a smooth and efficient assembly process, it's essential to follow these kitting guidelines. By properly preparing your parts, boards, and data, we can ensure accurate and timely production while minimizing delays and errors.
