High-technology PCB manufacturing from our facility in Tewkesbury, combining rigorous process control, experienced engineers, and the resilience of UK supply-chain manufacture.
Exception PCB provides DFM review embedded in the manufacturing process and as a standalone service for customers at earlier stages of development. Review is carried out by our in-house engineering team using In-Cam Pro, the industry-leading PCB layout analysis software.
Our engineers understand how PCBs behave in production, drawing on direct experience of lamination, drilling, plating, and inspection, and apply that knowledge to every review.
The service covers all PCB types, with particular specialism in HDI, flex, controlled impedance, and advanced material stack-ups.
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.
Exception PCB's DFM service is structured to support customers at different stages of their programme.
For customers placing manufacturing orders with Exception PCB, DFM is embedded in the production workflow as standard. Before any board reaches the production floor, our engineering team reviews design data, confirms production intent, and identifies areas of risk.
There is no separate process to initiate and no additional step to request. It is part of how we manufacture.
For customers at an earlier stage of development, DFM is available as a standalone service. This is suited to teams who want to validate designs before committing time and budget to production, whether at design freeze, pre-NPI, or during active development.
We provide a structured review and written report. No manufacturing order is required, and the service can be used as a one-off engagement or as part of an ongoing development programme.
Design errors that reach manufacture cost far more to resolve than those caught during review. For complex PCB programmes, the gap between a DFM change and a production re-spin can mean weeks of delay and significant additional expenditure.
Our engineering team works with customers to close that gap early. Customers typically benefit from:
DFM review applies to all PCB construction types but delivers the greatest value for complex and advanced designs, where the consequences of a design-to-manufacture conflict are most significant.
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.
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.
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.
READY TO DISCUSS YOUR DESIGN?
Whether you are at early design stage or preparing to move into production, 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.
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.
Exception PCB has installed the Orbotech Nuvogo 1000R, a laser direct imaging system that strengthens our capability for fine line, HDI, flex and rigid-flex PCB production at our Tewkesbury facility.
Exception PCB provides comprehensive engineering-led R&D support for new PCB materials and novel stack-ups. Our dedicated R&D team guides customers from initial requirements through to production-ready qualification and UL certification.
