Sovereign, trusted and well established with Aerospace, Defence and Security Primes and OEMs
Surface Technology International (STI) is a UK electronics manufacturing services partner specialising in complex, mission-critical systems. From our UK Sovereign accredited sites in Hook and Poynton, our engineers manufacture high-reliability electronic systems for defence, aerospace and security programmes.
Our capability spans PCB assembly, RF systems, wiring, environmental test and full product to systems build.
Chief Executive Officer, STI
STI has a heritage spanning more than three decades with well invested manufacturing facilities that deliver the highest quality production and testing in the UK.
Capabilities that deliver at every stage
We manage all stages involved in delivering complex electronic systems. Our teams validate design data, improve it for manufacture and test, source and control materials, build and integrate assemblies, verify performance and provide ongoing support. This joined-up approach reduces risk, shortens lead times and gives customers systems that work as intended from the start.

Life cycle process
Markets we serve
We work with defence, aerospace and security customers on programmes that depend on reliable electronic systems. Our teams deliver across land, air, sea and cyber, supporting applications such as sensing, communications and autonomous platforms.
Delivering critical and complex value
Our work supports advanced electronics across defence, aerospace and security. These brief case studies outline our role while respecting the confidential nature of the projects.
Re-engineering for urgent operational demand
We took an incomplete design that could not be built to print, strengthened the data pack, resolved component issues and delivered a manufacturable, tested system on an accelerated schedule.
Radar platform recovery
A complex radar subsystem was failing environmental and functional tests. Our teams reviewed the build approach, corrected wiring and RF issues, revalidated performance and returned the unit to service within the customer’s required window.
Obsolescence rescue
A mission system faced critical component obsolescence. We identified replacements, redesigned affected assemblies, secured the supply chain and extended the operational life of the system by several years.
Advanced UK capability for complex electronic systems
Qualified and experienced
All engineering and build carried out by qualified and experienced employees.
Complex builds under one roof
