Cap Air Systems is a UK-based electronics manufacturing partner, delivering precision, flexibility, and human-first support to innovators across Cambridge, the UK and beyond.
We assemble PCBs, cables and integrated systems, but what we’re really building is long-term trust.
We’ve got years of hands-on experience, and we’re still learning every day. We know how to deliver quality, and how to keep things moving when others stall.
Fast, flexible, and practical. We’ll adapt, problem-solve and communicate - without adding noise or nonsense.
We don’t just take a spec and build it. We ask the right questions, offer ideas, and work like we’re part of your team. Because that’s what partnership means.
We care about how we work. For your products, our people, our customers, our community, and our planet. Sustainability, in the truest sense of the word.
