Consignment PCB Assembly (Customer-Supplied Components)

Huayihai provides consignment PCB assembly for customers who supply their own components. In a consignment assembly project, the customer manages component procurement while Huayihai handles PCB fabrication, incoming material verification, SMT and through-hole assembly, inspection, and testing.

Consignment suits customers with locked component sources, approved supplier lists, or inventory already in stock. Materials arrive at Huayihai, are verified against the BOM before assembly, and every finished board passes the same inspection and 100% electrical testing as turnkey builds.

Custom Manufacturing Only

We provide consignment PCB assembly according to customer Gerber files, BOM, and technical specifications. We do not supply ready-made or standard products.

Service Specifications

Key Features

• Assembly with customer-supplied components

• Incoming material verification against the approved BOM

• PCB fabrication and assembly from one partner

• Same inspection and testing standards as turnkey builds

• 100% electrical testing on every assembly

• Controlled storage of customer materials before assembly

Manufacturing Highlights

In consignment builds, component quality depends on the customer's supply chain — so the process protects it with verification at the boundary: materials are checked against the BOM on arrival, stored in controlled conditions, and only released to the line after verification.

Key service elements include:

• Receiving and BOM verification of customer-supplied components

• Controlled storage before assembly

• PCB fabrication available from the same partner

• SMT and through-hole assembly with nitrogen reflow

• Multi-stage inspection: 3D SPI, AOI, 3D-AOI, X-ray

• 100% electrical testing of every board

Typical Applications

Consignment assembly fits programs where the customer owns the component supply:

• Approved Supplier List (ASL) Programs

• Locked or Allocated Component Sources

• Existing Component Inventory to Consume

• Long-Term Small Batch Supply

• Cost-Controlled Component Purchasing

• Other Consignment Assembly Projects

Why Choose Huayihai

• Over 20 years of PCB and PCBA manufacturing experience

• Same inspection and testing standards as turnkey builds

• Quality management based on ISO 9001, ISO 13485, IATF 16949 and UL

• Prototype, low-volume, and mass production support

Manufacturing Process

• Gerber file, BOM, and engineering drawing review

• Customer component delivery and incoming verification

• Controlled storage until production

• SMT assembly: 3D SPI, placement, nitrogen reflow, AOI

• Through-hole assembly: wave, selective wave, or DIP soldering

• X-ray inspection and 100% electrical testing

• Final inspection and shipment

FAQ

Q1: What is consignment PCB assembly?

The customer supplies the components; Huayihai handles PCB fabrication, verification, assembly, inspection, and testing.

Q2: How are customer-supplied components handled?

They are verified against the BOM on arrival, stored in controlled conditions, and released to the line after verification.

Q3: Can Huayihai also supply the bare PCBs?

Yes, PCB fabrication is available from the same partner under the same quality process.

Q4: What happens if components are missing or mismatched?

The discrepancy is reported against the BOM before assembly starts.

Q5: What is the standard lead time?

3–5 working days for samples and small batches, counted after materials arrive and file review is complete.

Q6: Can customer-supplied components be shipped in multiple deliveries?

Yes. Components can be received according to the agreed delivery plan before production.

Q7: Can consignment assembly include PCB fabrication?

Yes. Huayihai can manufacture the bare PCB and complete assembly while the customer supplies the components.
