Prototype PCB Assembly with 3-5 Working Days Lead Time, 100% Electrical Testing, and Same Quality as Volume Production

Prototype PCB Assembly

Huayihai provides prototype PCB assembly for OEM customers who need to validate a new design before committing to volume production. Assemblies are built according to customer Gerber files, BOM, and technical specifications.

Prototype builds run through the same engineering review, assembly process, and inspection standards as volume production — including AOI, X-ray, and 100% electrical testing — so validation results reflect real production quality. After validation, projects continue into small batch and mass production under the same process.

Custom Manufacturing Only

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

Service Specifications

Key Features

• Prototype and small batch assembly for design validation

• Standard lead time of 3–5 working days for samples and small batches

• Same inspection standards as volume production: 3D SPI, AOI, X-ray

• 100% electrical testing on every prototype build

• Nitrogen reflow soldering for reliable SMT joints

• Continuous support from prototype to mass production

Manufacturing Highlights

Prototype assembly at Huayihai is not a separate low-standard process: validation builds run through the same engineering review, assembly, and inspection steps as volume production.

Key service elements include:

• Engineering review of Gerber files, BOM, and specifications

• SMT assembly with 3D SPI and nitrogen reflow soldering

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

• AOI and X-ray inspection, including hidden-joint verification

• 100% electrical testing on every board

• Smooth transition from validated prototype to volume production

Typical Applications

Prototype PCB assembly supports projects where design correctness must be confirmed before volume investment.

• Engineering Validation Builds

• New Product Introduction (NPI)

• Design Iteration Projects

• Functional Sample Builds

• Pre-Production Verification

• Other Prototype Assembly Projects

FAQ

Q1: What is prototype PCB assembly?

It is the assembly of a small quantity of boards to validate a new design before committing to volume production.

Q2: How fast can a prototype build be completed?

Standard lead time is 3–5 working days for samples and small batches, after file review is complete.

Q3: Do prototype builds receive the same inspection as production?

Yes, prototype builds pass 3D SPI, AOI, X-ray inspection, and 100% electrical testing under the same standards as volume production.

Q4: What files are required to start?

We need Gerber files, the BOM, technical specifications, and quantity requirements.

Q5: Can the project continue to mass production after validation?

Yes, the validated design continues into small batch and mass production under the same engineering and quality process.
