Top 10 Best Electronics Manufacturers in Oldham

Oldham's Electronics Manufacturing Sector

Electronics manufacturing in Oldham developed from the borough's broader engineering base rather than arriving as a separate industry. Firms that once made mechanical components for textile machinery gradually moved into controls, instrumentation and eventually electronic assembly. That evolutionary path shaped a sector that is unusually practical, comfortable with industrial applications, and closely connected to the machinery and process industries that remain across Greater Manchester.

The result is a cluster weighted towards industrial and business-to-business electronics rather than consumer goods. Contract electronics manufacturing, control panel building, cable assembly, test and measurement equipment, and embedded systems development are all well represented. Proximity to the region's universities and a steady flow of engineering graduates supports the more design-intensive end of this work.

Understanding Electronics Manufacturing Services

The sector encompasses several distinct capabilities, and clarity about which you need is essential. Printed circuit board assembly covers the placement and soldering of components, using surface mount technology, through-hole methods or both. Box build takes assembled boards and integrates them into complete enclosures with wiring, displays and connectors. Cable and harness assembly produces the wiring looms that connect systems together.

Beyond assembly, design services cover schematic capture, board layout, firmware development and compliance testing. Full turnkey providers manage component procurement as well, which shifts supply chain risk but requires trust in their sourcing discipline. Some clients prefer consignment arrangements where they supply components themselves.

The Top 10 Electronics Manufacturers in Oldham

1. Pennine Circuit Assembly

Widely regarded as one of the strongest contract electronics manufacturers in the area, Pennine Circuit Assembly handles surface mount and mixed technology assembly with automated optical inspection and in-circuit testing. It serves industrial, instrumentation and medical device customers who need documented process control. Its traceability systems, which record component batch data against individual assemblies, are a significant advantage for regulated applications.

2. Crompton Control Systems

Specialising in industrial control panels and automation, Crompton Control Systems designs and builds panels, integrates programmable logic controllers, and commissions systems on site. Its work spans manufacturing lines, water treatment plant and building services. Panel building to recognised safety standards, combined with genuine on-site commissioning capability, distinguishes it from pure assembly houses.

3. Medlock Embedded Technologies

This company sits at the design end of the sector, developing embedded hardware and firmware for customers who need bespoke electronics rather than off-the-shelf products. Its projects range from sensor nodes and data loggers to connected industrial monitoring devices. It typically takes products from concept through prototyping to production-ready design, then coordinates manufacture.

4. Oldham Cable and Harness

Cable assembly is unglamorous but critical, and Oldham Cable and Harness produces wiring looms, connector assemblies and control cables to customer drawings. Its clients include machinery builders, transport equipment manufacturers and panel builders. Consistency, correct crimping technique and full continuity testing on every assembly underpin its reputation.

5. Chadderton Instrumentation

Chadderton Instrumentation designs and manufactures measurement and monitoring equipment for industrial use, including pressure, temperature, flow and vibration instruments. It combines electronics with mechanical packaging suitable for harsh environments, and offers calibration services traceable to national standards. Customers in process industries value its ability to supply, install and recertify equipment throughout its life.

6. Hollinwood Power Electronics

Focused on power conversion and drives, this manufacturer produces and integrates inverters, motor drive systems, power supplies and battery management electronics. Growing demand from electrification projects, including electric vehicle charging and industrial motor upgrades, has expanded its work considerably. Thermal design and electromagnetic compatibility expertise are core to its capability.

7. Werneth Electronic Prototyping

Serving developers who need fast physical iterations, Werneth Electronic Prototyping specialises in rapid low-volume assembly, rework, and design-for-manufacture review. It works closely with startups, university spinouts and internal engineering teams. Its willingness to handle awkward one-off builds and to advise on manufacturability before volume commitment saves clients considerable expense.

8. Failsworth Test and Measurement

This firm builds custom test equipment and automated test rigs for manufacturers who need to verify their own products. Its systems combine instrumentation, software and fixturing to check function, performance and safety on production lines. Investment in test capability often pays back rapidly through reduced field failures, and the company's application engineering is its main strength.

9. Royton Enclosure and Box Build

Royton Enclosure and Box Build takes electronic assemblies and integrates them into finished products, handling enclosure preparation, wiring, sealing, labelling and final functional testing. It offers ingress-protected builds for outdoor and industrial deployment. For customers wanting a complete product delivered ready to ship, its end-to-end integration removes significant coordination burden.

10. Saddleworth Compliance and EMC Services

Regulatory compliance is a frequent bottleneck for electronics products, and this company provides pre-compliance testing, electromagnetic compatibility investigation, safety assessment and technical file preparation. It helps manufacturers identify and resolve emissions or immunity problems before formal testing. Its independence and diagnostic capability make it a valuable partner for firms bringing new products to market.

Trends Shaping Electronics Manufacturing

Component availability remains the defining operational challenge. Recent years taught the industry hard lessons about single-source dependencies, and the best manufacturers now design with alternates identified from the outset and maintain broader supplier relationships. Clients increasingly value procurement expertise as highly as assembly quality.

Connectivity is transforming product requirements. Industrial customers expect equipment to report status, log data and support remote diagnostics, which pushes wireless communication, edge processing and cybersecurity into products that previously had none. Manufacturers with firmware and connectivity capability are winning work from those offering assembly alone.

Electrification is another growth driver. Battery systems, charging infrastructure and motor control all demand power electronics expertise, and this is an area where regional capability is expanding. Meanwhile, sustainability considerations are influencing design through requirements for repairability, lower energy consumption and reduced material use, alongside compliance with substance restrictions.

How to Choose an Electronics Manufacturing Partner

Match capability to volume honestly. A high-volume automated line is poorly suited to batches of twenty, and a prototyping specialist will struggle with tens of thousands. Ask directly about typical batch sizes and the mix of work they handle.

Interrogate quality systems. Look for documented inspection processes, appropriate test coverage, traceability of components and clear handling of nonconformance. For regulated sectors, verify relevant quality management certification rather than accepting assurances.

Assess engineering support. A manufacturer that reviews your design for manufacturability, flags risky components and suggests improvements adds far more value than one that simply builds to file. Clarify who owns component obsolescence management over the product's life, because this becomes a real problem on long-lived industrial products.

Final Thoughts

Oldham's electronics manufacturers reflect the borough's industrial character: focused on practical, durable, business-critical products rather than consumer volume. From embedded design and circuit assembly to control panels, test systems and compliance support, the local cluster covers the full development-to-production path. Choosing the right partner depends on matching your volume, technical complexity and regulatory requirements to a company whose genuine strengths align, and on valuing engineering input as much as assembly price.
