About Us

GSPK Circuits Ltd is the largest privately owned UK manufacturer of printed circuit boards. We have been proudly serving the global electronics industry for over 60 years. Our long-standing experience and technical expertise enable us to deliver high-quality engineering and manufacturing processes you can rely on. While we are proud of our heritage, we’re equally excited about the future.

We operate using world-class operational management systems, allowing us to deliver on time, every time—with quality built into every step of the process.

Driven by customer demand, our agile and responsive manufacturing capabilities allow us to handle high-mix, low-to-medium volume requirements with some of the shortest lead times in the industry.

For rapid PCB prototyping, GSPK Circuits offers a comprehensive range of surface finishes including lead-free HASL, immersion silver, ENIG, and ENEPIG. We are the only UK circuit manufacturer with an in-house ENEPIG line, allowing us to control quality, shorten lead times, and crucially—eliminate the need to send boards to external subcontractors.

We manufacture, test, and despatch conventional, double-sided plated through-hole, and multi-layer PCBs with speed and reliability—delivering to your schedule without compromising on performance.

As a specialist in application-specific PCBs, GSPK Circuits is the UK’s leading manufacturer of heavy copper boards for power electronics. Our proprietary processes support the growing demand for high-current solutions. For effective thermal management, we offer copper coin technology and advanced DTE (Direct Thermal Exchange) techniques that bond copper directly to aluminium substrates. We also manufacture HDI, RF/microwave, IMS, flex and rigid-flex boards, and embedded component PCBs—all produced in our North Yorkshire facility.

While our core strength lies in UK-based PCB manufacturing for high-volume production, we also operate dedicated offshore sourcing teams to deliver competitive pricing when required. These teams manage local quality assurance and logistics, ensuring a seamless service from factory to final delivery. We’ve developed long-standing partnerships with world-class PCB manufacturers, all of whom meet the exacting quality and technology standards our customers rely on.

Every project undergoes a full design-for-manufacture review to ensure the board is optimised for both performance and production. We’re known for our practical, problem-solving mindset—working closely with customers to deliver tailored solutions for demanding applications.
