UK PCB manufacturing for complex and high-technology electronics, from design validation through to production and time-critical delivery.
Accelerated PCB delivery for time-critical requirements, following the same inspection, process controls, and quality framework as standard manufacture.
DFM review carried out by our in-house engineering team, applying direct manufacturing knowledge to reduce risk and improve outcomes before production begins.
Exception PCB is a UK PCB manufacturer supporting complex, high-technology electronics across regulated and technically demanding programmes. We work alongside engineering, quality, and procurement teams, providing direct technical support from our UK facility.
Our services span UK manufacturing, quick-turn delivery, and design for manufacture, all supported by an in-house engineering team applying hands-on manufacturing knowledge. We work closely with customers to reduce technical risk and improve programme confidence at every stage.
Our enhanced solution search can help you to quickly find information about the service, technology, sector and resources you need.
Exception PCB provides a structured range of PCB manufacturing services for high-technology electronics. Each service is delivered with the same engineering discipline, quality framework, and commitment to technical accuracy.
From our 58,000 sq. ft facility in Tewkesbury, UK, we support high-technology PCB production for regulated and technically demanding applications.
Our controlled processes, embedded inspection, and full traceability support complex multilayer designs, advanced materials, and tight tolerances while maintaining consistency and audit readiness across every build.
UK-based manufacture reduces supply-chain risk, improves responsiveness, and supports secure handling of design data and materials. For customers in regulated and defence programmes, UK sourcing provides additional supply-chain assurance where country of origin matters.
Our Quick-Turn service provides accelerated delivery of high-technology PCBs for time-critical requirements across both prototype and standard builds.
This service is applied selectively where programme timelines require recovery or compression. Quick-Turn builds follow the same quality framework, inspection stages, and process controls as standard manufacture, ensuring predictability and traceability are maintained.
Quick-Turn is typically used to support urgent re-spins, compressed NPI schedules, or critical delivery deadlines, keeping programmes on track without increasing technical risk.
Our engineering team reviews designs against real manufacturing processes before production begins, assessing stack-up, materials, drill structures, impedance, and tolerances.
Review is carried out using In-Cam Pro, with direct input from engineers who work across lamination, drilling, plating, and inspection. This approach identifies manufacturability risks and confirms the right build route before fabrication begins.
For manufacturing customers, DFM is embedded in the production workflow as standard. For those at an earlier stage, it is available as a standalone review, providing structured recommendations before significant programme investment is committed.
We support a range of advanced PCB technologies used in complex and technically demanding electronics. Each technology is delivered using controlled processes and engineering oversight, with clear pathways into production.
Complex flex and rigid-flex PCB constructions for space-constrained and dynamic applications, built with reliability and repeatability in mind to support confident integration where weight, form factor, or movement are critical.
High-density interconnect PCBs for fine features, microvias, and complex multilayer designs, manufactured using production-ready processes with full engineering oversight to ensure reliable and repeatable fabrication of the most demanding constructions.
Support for specialist and hybrid PCB materials selected to meet thermal, electrical, and environmental performance requirements in applications where standard FR4 or conventional laminate systems cannot deliver the required performance.
RF and high-frequency PCBs built to support controlled impedance, low-loss materials, and consistent signal integrity in demanding applications where dielectric performance, layer registration, and material choice directly affect circuit behaviour.
Copper via filling for blind, buried, and through-hole vias, supporting HDI constructions, via-in-pad designs, and thermally demanding multilayer PCBs where electrical continuity, thermal performance, and consistent fill quality are required.
Resin via fill for blind, buried, and through-hole vias, providing consistent surface planarity to support via-in-pad designs, fine-pitch assembly, and sequential lamination builds where assembly quality and via integrity matter.
We work across sectors where reliability, traceability, and delivery confidence are critical. Our customers operate in some of the world’s most regulated environments and technically demanding programmes. Explore how we work across each sector.
Exception PCB brings together decades of manufacturing experience with ongoing investment in capability, people, and process. Our ten-strong engineering team works directly with customers, applying hands-on manufacturing knowledge to ensure designs are built correctly, risks are addressed early, and outcomes remain predictable.
As part of the Connexion Technologies group, a privately owned, UK-based business, we help strengthen UK manufacturing while supporting customers who value engineering ability, transparency, and reliable delivery.
Our manufacturing processes are supported by inspection at key stages, defined controls, and full traceability, backed by AS9100 and ISO 9001 certification.
We share updates on investment, capability, and industry insight to keep customers informed and support better decision-making across the PCB lifecycle.
UK-based PCB manufacturing is no longer just a sourcing choice, it is a strategic way to reduce supply chain risk, protect sensitive programmes, improve lead times and strengthen sovereign capability in high-technology electronics.
Chinese New Year supply chain shutdowns can affect PCB material availability globally. Exception PCB manufactures in the UK year-round, but early planning on materials, lead times, and substitutions protects time-critical programmes from disruption.
Wright Industries has acquired Exception PCB, returning the Tewkesbury-based PCB manufacturer to UK ownership as part of the Connexion Technologies group, strengthening national manufacturing resilience.
