When people think about electronics manufacturing, they often picture huge production lines manufacturing thousands or even millions of identical products.
In reality, many industries work very differently.
A large proportion of modern electronics manufacturing, particularly in sectors such as aerospace, defence, industrial equipment, medical technology, and specialist engineering, falls into what is known as “low volume, high mix” manufacturing.
But what does it actually mean?
What Is Low Volume, High Mix Manufacturing?
Low volume, high mix manufacturing refers to producing relatively small quantities of products, but with a large variety of different assemblies or configurations.
For example, instead of manufacturing 100,000 identical PCBs, a manufacturer like Active-PCB Solutions may produce 20 assemblies for one customer, 50 prototypes for another, a revised design iteration and several completely different products in the same production week.
It’s rarely the same from one day to the next and this type of manufacturing requires a very different approach compared to large-scale mass production.
Why Is Low Volume, High Mix PCB Assembly More Complex?
Every PCB assembly project comes with its own BOM requirements, assembly instructions, testing procedures, component availability, programming needs, inspection requirements and customer specifications.
In a high mix environment, production teams may move between completely different products several times a day.
That means success relies heavily on:
- Strong process control
- Detailed documentation
- Flexible manufacturing systems
- Skilled operators
- Accurate setup procedures
- Clear communication throughout the project
Without those things, errors, delays, and quality issues become far more likely.
Which Industries Use Low Volume, High Mix PCB Assembly?
Low volume, high mix manufacturing is common in industries where products are technically complex, frequently updated, and built in specialist quantities. The might be highly regulated or customised for specific applications.
This includes sectors such as:
- Aerospace
- Defence
- Industrial electronics
- Medical devices
- Scientific instrumentation
- Marine electronics
- Automotive development
- Communications equipment
These industries often prioritise reliability, traceability, flexibility, and engineering support over simply achieving the lowest possible unit cost.
Why UK PCB Assembly Is Well Suited to High Mix Manufacturing
UK manufacturers are often particularly well suited to low volume, high mix projects because they can offer faster communication, with easier collaboration and hand-on support throughout the production process. Because of their location they are often able to offer greater flexibility and better visibility.
For many companies, particularly those managing ongoing design revisions or complex supply chains, this level of responsiveness is critical.
While very high-volume manufacturing may suit large offshore facilities, low volume, high mix assembly often benefits from a more agile and collaborative manufacturing partner.
Inspection and Quality Control Matter Even More
In high mix environments, inspection and testing become even more important.
With multiple product types moving through production, manufacturers need robust systems to maintain quality and consistency across every build.
This can include Automated Optical Inspection (AOI), X-ray inspection, flying probe testing, functional testing as well as manual inspection.
At Active-PCB Solutions, we invest heavily in inspection technology and process control to support complex, high-reliability PCB assembly projects across a wide range of industries.
Communication Is a Major Part of Success
One of the most overlooked aspects of low volume, high mix manufacturing is communication. Because projects often evolve throughout production, maintaining close communication with customers is essential.
Lead times can change, components may become unavailable, and design revisions may need to be implemented quickly. A proactive manufacturing partner can help identify potential risks early and keep projects moving efficiently. Our account managers keep you in the loop, every step of the way.
Supporting Projects From Prototype to Production
Many low volume projects begin at prototype stage before progressing into repeat or scaled production.
Having a manufacturing partner capable of supporting this entire process can simplify project management, improve consistency, and reduce delays as products evolve.
At Active-PCB Solutions, we support customers from prototype PCB assembly through to full production, testing, box build, and system integration.
