Cambridge Circuit

What Cambridge Circuit does

Cambridge Circuit Company Limited is a privately held UK printed circuit board (PCB) manufacturer founded in 1994 and headquartered in Cambridge, England, operating from a single facility at 4 Winship Road, Milton. Its primary offering is complete PCB manufacturing services covering multilayer (4–12 layer at 1.6mm), flex, flex-rigid, plated through-hole (PTH), single-sided, and controlled impedance PCBs, all produced in-house. The company also supplies blind and buried via constructions and complements in-house capacity with trusted overseas partners for mass-volume production and UK assembly partners for end-to-end PCB assembly. The technology stack centers on Polar Instruments' CITS880s controlled impedance test system, Polar Speedstack PCB stackup software, and CGEN test coupon software for impedance verification, alongside a Penta 550 Hot Air Solder Leveller and Pure Water Recovery Systems on plating, immersion silver, and ENIG lines. All manufacturing processes are integrated within an ISO 9001:2015 quality management system, and the company additionally holds ISO 14001:2015 environmental management certification, UL certification for Type 1 and Type 2 printed wiring boards, RoHS and REACH compliance, and a conflict minerals statement.

Cambridge Circuit generates revenue through project-based, quote-driven one-time manufacturing fees for prototypes and production runs, with no subscription or recurring component. Pricing is not publicly listed; customers request quotes via an online quotation form, telephone (01223 423100), or email, and lead times start at 8 hours for prototypes with 5-day delivery as standard. Its target customers are B2B electronics manufacturers requiring custom PCBs from prototype through production, with named clients historically including Tyco, Toshiba, and Phillips, and a documented current testimonial relationship with SIL (enLight). The go-to-market is sales-led, supported by content marketing through a company blog, LinkedIn, X, Facebook, and YouTube, plus community sponsorships with Milton Football Club, Cambridge University Space Flight, Cambridge University Eco Racing, and the Cambridge Autonomous Underwater Vehicle project.

The company is family-led, with founder Phil Sanford and Managing Director Mark Sanford (also Data Protection Officer) at the helm, alongside a Director named Guy and a workforce of 11–50 employees. Cambridge Circuit has remained privately held with no disclosed external investors, no funding rounds, and no M&A activity; it has navigated operational setbacks including a February 2017 factory fire from which it recovered to full capacity by May 2017, and it continues to operate actively as of September 2025 per recent blog posts.

Revenue model

1. PCB Manufacturing (In-house): Manufacture and sale of printed circuit boards including multilayer, flex, flex-rigid, PTH, and single-sided PCBs. Prototypes and fast turnaround are a specialism, with lead times from 8 hours and 5-day delivery as standard. Revenue is generated through one-time project-based manufacturing fees, with no subscription component.
2. Mass-Volume Production via Overseas Partners: Efficient mass-volume PCB production is outsourced to trusted strategic overseas partners for larger volume orders, complementing in-house capabilities.
3. UK Assembly Service: Assembly service via UK assembly partners, providing a complementary end-to-end offering for customers requiring fully assembled PCBs.

Functional benefit

Products and services

• Multilayer PCB Manufacturing Manufacture of multilayer printed circuit boards including 4, 6, 8, 10, and 12 layer configurations at 1.6mm thickness, produced entirely in-house for B2B electronics manufacturers and product developers.
• Flex and Flex-Rigid PCBs Flexible printed circuit boards and combined flex-rigid constructions that can bend or flex during use, enabling complex 3D configurations and dynamic form factors for B2B electronics manufacturers.
• PTH (Plated Through Hole) PCBs Standard through-hole PCBs with plated through-holes providing reliable electrical connections between layers, manufactured in-house for B2B electronics customers.
• Single-Sided PCBs Basic single-layer printed circuit boards with components mounted on one side, suitable for simple electronic applications, produced in-house.
• Controlled Impedance PCBs PCBs designed with precise impedance control for high-frequency applications, manufactured in-house and verified using Polar Instruments CITS880s, Speedstack PCB software, and CGEN test coupon software; for B2B electronics customers needing signal integrity.
• Blind & Buried Via PCBs Advanced PCB via structures — buried vias connect inner layers without penetrating the entire board, and blind vias connect outer to inner layers without going through the full board — enabling higher density designs for B2B electronics manufacturers.
• PCB Prototyping Service Fast-turnaround PCB prototyping service with lead times from 8 hours and 5-day standard delivery, enabling rapid design iteration and testing for B2B electronics developers.
• Mass-Volume PCB Production (via Overseas Partners) Efficient mass-volume PCB production outsourced to trusted strategic overseas partners, complementing in-house capabilities for larger volume orders placed by B2B electronics customers.
