Sum of the parts. Briton EMS and Union Four Electronics became OSI Electronics UK in 2017.

About

We make electronic products – any volume, size, shape or function – for other people in the UK, USA and Asia.

Our manufacturing skills put quality and efficiency first, allow for flexibility in your product mix and spec and help to speed your product to market.  These skills are the building blocks to successful electronics production.

We are part of California based OSI Systems – see our OSI family page.  OSI Electronics (UK) Limited was incorporated in August 2017 – after uniting the highly experienced CEMS companies Briton EMS and Union Four Electronics several months earlier.

With a strong financial base, OSI Electronics UK is a £20m and growing global player of contract electronics manufacturing services (CEMS) – including advanced PCB assembly, full box build, rigorous testing, CE marking and shipping to anywhere in the world.

We will work with you on your new product introduction (NPI) and device programming or help you to upgrade an existing product.  Do have a look at our NPI + DfM as well as the Electronic design services pages.

HQ and customer base

Our headquarters and PCB / sub-assembly / box build manufacturing centre is in our newly enlarged St Neots facility.

Who are our customers?  They are mainly in the broadcast, industrial, instrumentation, medical, oil and gas, aerospace, security, counter terror, agricultural, telecoms and transport electronics and infrastructure sectors.

That’s quite a broad base – which has expanded since we added ISO 13485 for medical devices to complement our ISO 9001 and ISO 14001 (environmental management) accreditations, and the filtering through of opportunities from international collaboration.

We are also an approved sub-contractor under the ATEX Directive and a certified sub-contractor for UL Approved Products.

Our PCB manufacturing process is certified IPC-A-610 Class 3, Acceptability of Electronic Assemblies.  Class 3 is the highest class.

Complete contract electronics
Our focus is on complete manufacturing services, including mechanical, electro-mechanical and electronics box build from prototype to testing, packaging and shipping to anywhere in

Our focus is on complete manufacturing services, including mechanical, electro-mechanical and electronics box build from prototype to testing, packaging and shipping to anywhere in the world.

We offer turnkey electronic assembly, design for manufacturing advice, multiple PCB assembly lines and outstanding test resources for the demanding customer, whether a tier 1, 2 or 3 supplier.

And whether for RF systems, sensors, high speed data, medical, instrumentation, security or transport applications, our expertise and experience will get the job done for you on time and within budget.

High volumes

Investment in our UK operation by our parent company OSI Electronics enabled us to consolidate our Briton EMS and Union Four operations on the Union Four site in St Neots.

The site has more than doubled in the size, enabling us to streamline operations, maximise efficiencies and improve communications – and be competitive with our pricing.

It also means we can produce a wider variety of sub-assemblies, complete products and PCBs in the UK at an equally wide variety of volumes from low to medium-high, depending on the type of product and your requirements.

These changes further strengthen the case for reshoring some higher value products to the UK.

For very high volumes, we have direct access to manufacturing in Indonesia and Malaysia – see below.

Prototypes in days
Competitors say ‘rapid prototyping’. We say ‘fast prototyping’ – your prototype can be delivered and ready for field testing by you in days from receipt

Competitors say ‘rapid prototyping’.

We say ‘fast prototyping’ – your prototype can be delivered and ready for field testing by you in days from receipt of engineering data.

Once we have all the components – either free issued from yourselves or sourced by us – we’ve a line in St Neots dedicated to prototype production, including full quality inspection to the same standards as for series production.

This allows you to test functionality with your customers – and not worry whether the quality of manufacture is good enough. There’s more about this service on our Fast prototyping page.

Lower cost overseas manufacturing, too
Through OSI Electronics, we have access to lower cost manufacturing sites in Indonesia and Malaysia and specialist facilities in the USA – we would

Through OSI Electronics, we have access to lower cost manufacturing sites in Indonesia and Malaysia and specialist facilities in the USA – we would manage the transition from the UK on your behalf, integrating your electronics manufacturing requirements through one source.

It enables us to work with you in the UK to develop your products and run trial quantities locally before switching production overseas.

For example, if it’s a product destined for sale in the USA, production can switch to OSI’s factory in Hawthorne, California.

In addition to ISO 9001, ISO 13485 and ISO 14001 approvals, the plants have AS 9100 certification for aerospace, defence and military work and ISO/TS 16949 for automotive applications.
