Low Volume PCB Assembly

Low Volume PCB Assembly Services

When you need assembled PCBs without committing to a large production run, our low volume PCB assembly services give you the flexibility to build the quantity your project requires. As a low volume PCB manufacturer, we support prototype builds, pilot runs, product revisions, and limited production requirements based on your PCB design, BOM, assembly requirements, and schedule.

Our Chino, California facility provides U.S.-based engineering support, backed by 30+ years of industry experience, ISO 9001:2015 and AS9100D certifications, and ITAR registration. For qualifying projects, 24-hour turnaround may be available for qualifying projects after reviewing your assembly requirements and production schedule.

Low Volume PCB Assembly for Your Production Requirements

Low-volume assembly is useful when you need a limited number of boards without committing to a large production run. Our small volume PCB assembly services support:

• Prototype and engineering builds
• Pilot and pre-production runs
• Small-batch production
• Product revisions
• Repeat low-volume builds
• Specialized electronic assemblies

Each project is reviewed according to its board design, components, quantity, and production requirements.

Our Low Volume PCB Assembly Capabilities

 Engineering Review Before Assembly

Your assembly files need to provide the information required for production. Our engineering team reviews the available documentation before assembly to identify manufacturing questions that may need to be resolved. Depending on your project, we may review:

• Gerber or ODB++ files
• Bill of Materials (BOM)
• Pick-and-place data
• Schematics
• Assembly drawings
• Component requirements
• Testing requirements

This review gives you an opportunity to address manufacturing issues before your boards move into assembly. Have your files ready? Send us your PCB assembly requirements for review and a quote.

Component Sourcing Support

If you need help obtaining components, our team can support sourcing based on your approved BOM and project requirements.
If you prefer to supply the components yourself, we can work with customer-supplied materials where applicable. Component availability is considered when we review your project schedule.

SMT, Through-Hole, and Mixed-Technology Assembly

Your low volume PCB design determines the assembly method required. We support SMT, through-hole, and mixed-technology PCB assembly for applicable projects.
SMT is commonly used for surface-mount components and compact board designs. Through-hole assembly is used where the design calls for through-hole components. If your board uses both, we can support the required mixed-technology assembly process.

Inspection and Testing

The inspection and testing required for your assembly depend on the board design, components, and application.

 
We can review your testing requirements and determine which inspection or testing processes apply to your project.

Benefits of Low Volume PCB Assembly

Our low-volume approach can be useful when you need to:

• Limit Initial Inventory: Build only the quantity required for your current project stage.
• Validate a Design: Assemble boards for evaluation before moving to larger production quantities.
• Manage Design Changes: Make revisions without committing to a large existing inventory.
• Support Pilot Builds: Produce a limited quantity for product or customer evaluation.
• Continue Limited Production: Maintain repeat builds when your product does not require high-volume manufacturing.

24-Hour Turnaround for Qualifying Projects

If your project has a tight schedule, we may be able to support 24-hour PCB assembly turnaround for qualifying projects.
We confirm turnaround after reviewing factors such as component availability, board complexity, quantity, materials, testing requirements, and other project-specific requirements.
If you need an urgent build, send us your project files and required delivery date so we can review the available schedule.

Frequently Asked Questions

1. What information should I include in my BOM for a low volume PCB assembly quote?
Ans: Provide the component part numbers and required quantities. Include approved alternatives when they are part of your project requirements.

2. Should my PCB design and BOM be from the same revision?
Ans: Yes. Your PCB files, BOM, placement data, and assembly drawings should correspond to the same design revision to help prevent assembly errors.

3. When should I request DFM review?
Ans: Request DFM review before assembly begins. This allows potential manufacturing concerns to be identified while changes can still be made.

4. Can a low volume PCB use both SMT and through-hole components?
Ans: Yes. A board can use both technologies. The required assembly process depends on the component types and PCB design.

5. What can cause a PCB assembly schedule to change?
Ans: Component availability, board complexity, quantity, material requirements, testing, and other project-specific requirements can affect the production schedule.
