Garner Osborne Circuits

What Garner Osborne Circuits does

Garner Osborne Circuits Limited is a UK-based Contract Electronics Manufacturer (CEM) operating from a single factory in Newbury, Berkshire. The company provides a full vertical PCB service offering — printed circuit board manufacturing, PCB assembly, box build, and functional testing — from prototyping through mass production, with capabilities spanning rigid, flexible, and rigid-flex boards up to 8+ layers, surface mount technology assembly, and offshore-brokered high-volume production under Kanban arrangements.

The company differentiates on quality and certification rather than scale, holding AS9100D (since 2013), ISO 9001:2015, ISO 13485:2016 (since 2020), UL, and JOSCAR registration, which collectively qualify it for aerospace, defence, and medical device supply chains. In-house equipment investment includes the Altus X-Spection 6000 X-Ray Inspection system, Emma ELX6146 flying probe tester, Type IV solder paste as standard (claimed to drive a 100% PCB accuracy rate), and an 8-cell copper plating line with pulse engines. The company employs a B2B sales-led go-to-market with dedicated account managers and an online quote tool, generating revenue through one-time project fees for direct manufacturing plus transaction-fee brokerage for offshore-brokered Kanban volume.

In August 2025, Garner Osborne Circuits formed Agile Circuit Technology Group, a strategic alliance with Active-PCB Solutions Ltd that combines 62 years of heritage and over 1,000 years of cumulative PCB manufacturing experience while keeping both entities operationally independent. The group is led by Group CEO Dean Curran, Group COO Mark Aitken, and Group CFO Jamie Oldham, and serves customers across aerospace and defence, medical devices, IoT and electronics innovation, and industrial and automotive verticals — all within a UK-domiciled market footprint.

Revenue model

1. PCB Manufacturing: Full-service printed circuit board manufacturing from prototyping to mass production. Services include rigid boards, flexible boards, rigid-flex boards, and multilayer boards up to 8+ layers. Revenue generated through one-time project fees based on board complexity, quantity, and material specifications.
2. PCB Assembly (PCBA): PCB assembly services using state-of-the-art surface mount technology (SMT) capable of placing up to 10,000 components per hour. Includes box build and functional testing services.
3. Prototype and Low Volume Production: Quick-turn prototyping and low volume PCB production for product development and testing. One-off pieces or small quantities available.
4. Kanban/Brokerage Services: High volume PCB production using offshore partners operating within strict quality assurance procedures. Customers benefit from lower costs of offshore fabrication with UK-based quality oversight and customer service. Stock holding and Kanban services available.
