Kit Circuit Board Assembly Turn Key PCB Assembly With Customer Supplied Parts

Some customers have already invested significant time and resources in building their component supply chain. They have established relationships with specific distributors, negotiated favorable pricing, and qualified components for their designs. For these customers, the ideal manufacturing solution is one that respects their supply chain investment while leveraging the advanced assembly capabilities of a professional EMS provider. Our Kit Assembly Turnkey PCBA with Customer-Supplied Parts is designed exactly for this scenario. You provide the components (the kit); we provide the assembly, soldering, inspection, testing, and final packaging.

When you ship your kit to us, we process it through our advanced manufacturing facility—12 fully automated SMT production lines, automated wave soldering, programmable robotic soldering, and a full suite of inspection equipment including AOI, SPI, 3D X-Ray, ICT, FCT, flying probe testers, and an accredited reliability laboratory. The result: your components, assembled to the highest standards, with full traceability back to your supplied parts.

Kit assembly—also known as consignment assembly—is a manufacturing model where the customer supplies all or most of the components required for assembly. The manufacturer is responsible for receiving, storing, and verifying the customer-supplied materials, then assembling and testing the boards using their production infrastructure.

At Studio, our kit assembly service includes:

• Receiving & Verification – We receive your kit, verify quantities against your BOM, and inspect components for damage or mislabeling

• ESD-Safe Storage – Your supplied components are stored in ESD-protected areas with environmental controls

• Incoming Inspection – We perform LCR testing and visual inspection on supplied components to confirm basic functionality and spec compliance

• Assembly Execution – Your components are placed and soldered using our 12 automated SMT lines and soldering systems

• Inspection & Testing – All assemblies undergo AOI, SPI, X-Ray, ICT, and FCT verification

• Remaining Balance Management – We return unused components or handle them per your instructions

Step 1: Kit Receiving & Verification

When your components arrive, we compare the shipment against your BOM and packing list. Quantities are verified, components are inspected for physical damage, and any discrepancies are flagged immediately. All components are logged into our MES system with lot numbers and supplier information.

Step 2: Incoming Component Inspection

Customer-supplied components undergo LCR testing and visual inspection before they are loaded onto our production lines. This step confirms that the parts you provided match their specifications and are suitable for the assembly process.

Step 3: ESD-Safe Storage & Kitting

Approved components are stored in our ESD-controlled environment until production begins. We kit components per your order, ensuring the correct parts are staged for each assembly run.

Step 4: Precision Assembly

Your supplied components are placed and soldered using our advanced SMT lines. Our 12 automated SMT production lines handle high-density designs with 01005, micro-BGA, and fine-pitch capability. Automated wave soldering and robotic selective soldering ensure consistent through-hole and mixed-technology assembly.

Step 5: Comprehensive Inspection & Testing

Every assembled board undergoes our full inspection and testing suite:

Step 6: Component Reconciliation & Return

After assembly, we reconcile your components: which parts were used, which parts remain. Any unused components are returned to you per your instructions, or stored for future orders.

• Respect for Your Supply Chain – We do not require you to use our procurement; we work with your supplied parts

• 12 Automated SMT Lines – Precision assembly for any board complexity

• Comprehensive Inspection – AOI, SPI, X-Ray, ICT, FCT on every board

• Full Traceability – Your supplied components tracked through our MES system

• Component Security – ESD-safe storage and careful handling of your parts

• Reconciliation & Return – Clear accounting of all supplied materials

You have already invested in your component supply chain. Let us provide the manufacturing excellence that completes the journey. With Studio's Kit Assembly Turnkey PCBA with Customer-Supplied Parts, your components are handled with care, assembled with precision, and tested to the highest standards.
