Over 35 Years of Precision PCB Assembly & UK Electronics Manufacturing
Your products. Our engineering. Built with care, accuracy and pride.
Since 1988, Phase One Electronics has supported UK businesses with dependable PCB assembly, electronic manufacturing, prototyping and complete system builds. With more than three decades of experience, our team delivers consistent quality, reliable lead times and engineering-focused support for marine, medical, automotive, defence, communications and industrial sectors.
A Legacy Built on Engineering Excellence
Phase One Electronics was founded in Portsmouth in 1988 by Tony Stanley, an experienced engineer with a background in Commercial, Military and Space industries. From the beginning, Tony recognised that many UK businesses depended on overseas PCB assembly and often faced long lead times, communication challenges and inconsistent quality.
Phase One was created to offer something different: a skilled, local electronics manufacturing partner that could support British engineering with reliable build quality, transparent communication and genuine technical understanding. Over more than three decades, that vision has grown into a respected, long-standing electronics manufacturer that many customers have trusted for years.
Today, Tony’s passion for precision and workmanship still sits at the heart of our business. His belief in high-skill UK manufacturing and investment in people has shaped Phase One Electronics into:
- A team of experienced engineers and assembly specialists
- A facility equipped for SMT, through-hole, prototyping and cable assembly
- A business built on strong relationships and long-term customer trust
- A trusted partner known for reliability, technical understanding and consistent results
More than thirty five years later, our ethos remains unchanged: skilled people, reliable processes and products built properly.


A Team Built on Skill, Care and Professionalism
Our employees are the reason Phase One Electronics has earned a reputation for consistent, high-quality electronic assembly. Many of our engineers and technicians have been with us for years, bringing valuable experience and deep attention to detail to every build.
We approach each PCB with the mindset that someone’s equipment, system or product depends on it performing correctly. This culture of care is what makes the difference between an assembly line and a professional electronics manufacturing team.
