Professional engineer review; strict quality control for each process.

Advanced Testing Technology To Ensure the Quality such as AOI Test, E-Test, X-RAY, Impedance Control.

We committed to helping customers get the highest quality products and services with competitive prices (especially multilayers PCBs).

Like high-volume PCB assembly, low-volume PCB assembly services include bare board fabrication, component placement, soldering, testing, and delivery. The only difference is the order quantity.

We can handle both types of orders, so if you need low-volume PCB assembly, contact us to get free quotes with reasonable pricing for your prototypes, specialized projects, and small batches.

What is Low Volume PCB Assembly?

Low-volume PCB assembly refers to manufacturing and assembling circuit board orders that typically range from only 25 pieces to 5,000 units.

You might need such low order quantities if you’re starting an electronics project/business, testing a new product line before launch (prototyping), or have a small niche market, especially if the complete device is expensive and high-end.

Benefits of Low-Volume PCB Assembly

Low Volume PCB Assembly Benefits

Low-volume PCB assembly introduces several benefits to the electronics business environment, including:

Cost Effectiveness

Mass or high-volume production of a new, untested design or circuit upgrade can be buggy. Such products are likely to have negative feedback from the market, resulting in expensive recalls and market share losses that will affect cash flow in the future.

Low-volume PCB production might seem expensive at first, but it’s a cost-effective part of the RnD process that enables prototyping and fine-tuning. This ensures that the product that ends up in the market is the best possible version.

Quick Turnaround

Low-volume production is synonymous with prototyping and falls in the same category as quick-turn PCB manufacturing. Therefore, you’ll get your PCBs in 1 to 7 days, depending on the board’s complexity and the exact number of pieces.

This quick turnaround helps you fine-tune the product quickly and launch the final device in the market within a reasonable timeline.


With the quick turnaround and cost-effectiveness, low-volume production makes it possible to alter the design and change electronic component specifications quickly to improve performance. You can even do tweaks in several prototyping iterations/versions because the cost is manageable.


Each PCB in the low-volume assembly batch undergoes various checks and rigorous tests to produce the highest-quality product. And since they are few, we’ll be able to commit more resources (time and components) to each piece, which will have a positive impact on quality.


Since we’ll be able to commit more resources to low-volume assembly, the resulting high-quality PCBs will be more reliable. The risk of making mistakes will be lower than when handling large orders in the same time frame.

PCB Design and Layout

We provide a PCB layout design service for low-volume circuit board assembly, which is handy if you only know little about electronic product design. All you have to do is give us the information about your product, including its functionality and installation environment.

Our team of engineers and designers will build and optimize the layout for manufacturing and efficiency. We’ll send you the design files and prototypes later for testing and fine-tuning.

We have experience in various fields, including:

  • Real-time control
  • Network remote control
  • Smart home devices
  • Solar and wind (clean energy devices)
  • Game consoles
  • Embedded systems
  • Video sampling
  • And many others

Therefore, we can design all types of boards with complex configurations and multiple layers, then customize them to meet your specific requirements.

Design for Manufacturability (DFM) Review

If you can handle the design process yourself, the first step is to send us your files for a DFM analysis. This process helps to identify potential bottlenecks that could lead to manufacturing failures, production delays, or high fabrication costs.

We use tools like signal, plane, and solder mask checks, then recommend the best changes to make.

PCB Fabrication

Once the design passes the DFM review and we get your approval, we’ll begin manufacturing. Our experts can build PCBs with various substrate materials like metal (usually aluminum), ceramic, and the most popular one, FR4.

We can fabricate these boards as single-sided (single-layer) or double-sided (multilayer), with the latter having up to 50 layers that can form a dense, complex assembly.

Electronic Component Sourcing

We stock the most common components, such as resistors, transistors, diodes, and capacitors, for quick assembly. If it’s a unique part, we have a global sourcing network that boasts of partnerships with authorized distributors like Avnet, Arrow, Mouser, and Future Electronics.

This network gives us access to high-quality electronic components at competitive prices, which will help lower the overall cost of your project.

These components undergo verification and testing to check their authenticity and functionality, which will reduce or eliminate reliability issues in the prototypes and final products.

Conformal Coating

A conformal coat is a moisture-proof layer that’s necessary for waterproof PCBs. It protects them from dust, water, and temperature extremes when installed outdoors in aerospace or automotive applications. This agent can be materials like epoxy, silicone, urethane, and acrylic.

Epoxy is super adhesive and can handle high temperatures (205°C/401℉ max), making it ideal for automotive applications. On the other hand, silicon is soft and pliable, while urethane is flexible, stretchable, and abrasion-resistant. Acrylic provides some level of chemical resistance, and these properties make the materials suitable for unique applications.

IC Programming

Programming chips from the factory or distributor reduces the assembly time because we only have to solder these parts. But we can also program these boards during assembly using universal or dedicated headers, manufacturing/test jigs, or offline and online methods.

Either way, we’ll customize this IC programming to meet your specifications for the final product to ensure it is fully functional.

Testing Services

With the PCB fabricated, we test it before assembly using these methods.

  • Functional Jig Tests: A test jig contains pogo pins that contact the test points on the board to inject power and test its functionality (real-world operating conditions).
  • Burn-in Tests: This process pushes the PCB to its limits by subjecting it to abnormal conditions like high temperatures for a specified time. The goal is to detect early failures and ensure long-term reliability.
  • Comprehensive Testing Capabilities: Other tests, like solderability and contamination, are necessary for boards made for demanding tasks in aerospace, military, satellite, and telecommunication applications. These must be highly reliable.

Prototype Assembly

To speed up the prototyping process, we use techniques like CNC machining and quick turnaround services (with chemical etching, not machining) to build the test board. 

Whatever your PCB needs, we’re here to help. We’ll optimize the process to meet your project requirements. Reach out today to get started.

Assembly Technologies Used in Low-Volume PCB Assembly Services

Assembly Technologies Used in Low-Volume PCB Assembly Services
Low-Volume PCB Assembly Services Technologies
  • Surface Mount Technology (SMT): This technology involves mounting tiny components on the PCB surface (copper pads), which makes it possible to create miniaturized circuits.
  • Thru-Hole Technology (THT): Thru-hole components are large, and this technology mounts their leads inside plated holes on the PCB to hold them firmly.
  • Mixed Technology: A mixed assembly has both SMT and THT, which makes the PCB more robust because it can have the most optimal hardware, be it large or small.

Low Volume PCB Assembly Services FAQs

We can handle all component sizes, including the fine-pitch type (as small as 8 mils), passive parts like the 0201 (20×10 mils), BGA, and all chip carriers (leadless and leaded).

We can use leaded or lead-free solder, depending on your requirements. For instance, if you want to make consumer electronics, we use lead-free solder for RoHS compliance. But for applications that require high reliability, such as in military electronic devices, leaded solder might be better.
