Secure, UK-based PCB manufacturing for defence and security applications, delivering controlled processes, traceability and reliable performance for mission-critical systems.
Exception PCB provides defence PCB manufacturing services for companies across the UK and Europe, producing high-reliability printed circuit boards for security and defence applications where performance, confidentiality and manufacturing control are critical.
We support customers developing systems across air, land, naval, surveillance, communications and electronic warfare programmes. Manufacturing takes place within our UK facility in Tewkesbury, providing customers with greater control over sensitive technologies and supply chain risk.
Our engineers work with defence customers from initial design review through to production, supporting traceability, qualification, and supply-chain assurance at every stage.
Defence organisations increasingly require trusted UK manufacturing capability to support programme security and long-term resilience.
EXCEPTION PCB PROVIDES:
This helps reduce exposure to offshoring risk while supporting sovereign capability objectives.
We support a broad range of defence and security systems.
TYPICAL APPLICATIONS INCLUDE:
Modern defence electronics rely on increasingly compact, high-density and high-frequency PCB architectures.
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.
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.
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.
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.
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 support defence programme teams that require clear, documented evidence of manufacturing discipline, process stability, and repeatability.
Defence development programmes often move quickly through design refinement, testing and validation phases.
We support:
This allows engineering teams to maintain programme momentum without compromising manufacturing control.
Environmental requirements vary significantly across defence applications, depending on the operating environment, material selection and system architecture.
This provides engineers and quality teams with confidence in structural and electrical performance.
Defence programmes often extend across many years, requiring stable supply and manufacturing consistency over time.
Customers value:
We work closely with programme teams to support both immediate development requirements and long lifecycle manufacturing needs.
SPEAK TO OUR ENGINEERING TEAM
If you are developing defence electronics and require secure, UK-based PCB manufacturing, our engineers are ready to support your programme.
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.
