How PCB Design Decisions Can Affect Manufacturing
PCB design decisions, from via placement to material selection, can significantly affect manufacturing time, complexity and efficiency, making early DFM input essential.
UK PCB MANUFACTURING
High-technology PCB manufacturing from our facility in Tewkesbury, combining rigorous process control, experienced engineers, and the resilience of UK supply-chain manufacture.
WHAT WE MANUFACTURE
Exception PCB manufactures complex printed circuit boards at our 58,000 sq. ft UK facility in Tewkesbury, supporting customers across regulated and performance-critical sectors.
We build our manufacturing capability around process control, repeatability, and full visibility throughout production. Whether we are supporting early-stage prototypes or stable production volumes, the same engineering disciplines apply.
Our engineers bring deep process knowledge to every build, giving customers direct access to the expertise behind the manufacturing capability.
LET OUR ENGINEERS REVIEW YOUR DESIGN
Whether you are preparing for prototype or moving into production, our team will confirm the right manufacturing route and identify any risks before your build begins.
PCB MANUFACTURING PROCESS
Every PCB we manufacture follows a defined route, with inspection and verification integrated at each stage from design review through to dispatch.
QUALITY AND ASSURANCE
We support manufacturing quality through documented procedures, controlled process routes, and full traceability across production.
Our systems support:
- AS9100 and ISO 9001 manufacturing standards
- IPC Class 2 and Class 3 manufacture
- Material and process traceability
- Structured inspection and reporting
- Controlled documentation
Customers benefit from clear visibility into how boards are manufactured, inspected, and released.
ADVANCED PCB MANUFACTURING TECHNOLOGIES
Our manufacturing capability covers a broad range of PCB technologies, from standard multilayer construction through to HDI, flex, rigid-flex, RF materials, and hybrid builds. Detailed information on each technology area, including materials, construction approaches, and manufacturing considerations, is available on the pages below.
Flex & Rigid-Flex
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.
HDI
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.
Advanced Materials
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 Fill
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.
RF
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.
Resin Via Fill
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.
WHY UK MANUFACTURING MATTERS
For many customers, PCB manufacture is about more than lead time alone.
UK PRODUCTION PROVIDES:
- Reduced geopolitical and logistics risk
- Greater visibility across the supply chain
- Faster engineering communication
- Improved protection of sensitive data
- Support for reshoring and sovereign capability strategies
This gives our customers greater confidence at every stage of the programme.
OUR INVESTMENT IN UK MANUFACTURING
We continue to invest in equipment, automation, and process capability to improve repeatability and manufacturing control.
RECENT INVESTMENTS INCLUDE:
- Automated plating systems
- Advanced imaging equipment
- Flying probe test systems
- X-ray registration technology
- Process monitoring systems
This investment strategy supports both rapid development and long-term production scalability.

How Exception PCB Supports Customers Through the PCB Materials Supply Pressures
PCB supply chain disruption is pressuring FR4 laminate availability, lead times, and pricing. AI and data centre demand is absorbing glass fabric capacity, putting standard FR4 at risk of allocation.
Why UK Manufacturing Matters for Sovereign Capability
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.
