What Is Turnkey PCB Assembly?
Turnkey PCB assembly is a complete manufacturing service that manages the full production process, from component sourcing and procurement through to PCB assembly, inspection and testing. It allows businesses to work with one experienced supplier rather than coordinating separate companies for parts, assembly and quality control.
Altimex has more than 30 years of experience in PCB assembly and bespoke electronic production. From its Cheshire facility, the team delivers surface mount, through-hole and mixed technology assemblies for sectors including aerospace, automotive, telecommunications, defence and maritime. Each project is managed through component verification, controlled assembly, inspection and testing to maintain quality, traceability and reliable production outcomes.
Our Mixed Technology PCB Assembly Capabilities
Altimex combines surface mount and through-hole assembly processes to manufacture PCB assemblies containing a wide range of component types. Each stage is planned around the board layout, component requirements and expected production volume, supporting accurate assembly from prototypes through to repeat production.
Altimex uses automated surface mount assembly equipment for the accurate placement of compact and fine-pitch components. Controlled solder paste application, component placement and reflow soldering support consistent results across prototypes, low-volume batches and repeat production.
Through-hole components are inserted and soldered using controlled manual or automated processes. This method is suited to connectors, transformers, larger components and parts that require strong mechanical connections or additional support.
Surface mount and through-hole components are assembled on the same PCB using a planned production sequence. Our engineers review component placement, soldering requirements and thermal considerations to reduce manufacturing risks and maintain consistent assembly quality.
Mixed technology PCB assemblies are inspected throughout production using visual checks, automated inspection and testing options based on the project requirements. Work is completed in line with IPC-A-610 and IPC-J-STD-001 standards.
Component Sourcing for Turnkey PCB Assembly
Altimex provides component sourcing for turnkey PCB assembly, covering surface mount, through-hole and mixed technology production. Components are sourced through established suppliers, with checks carried out on specification, compliance, availability, lead times and traceability before assembly begins.
Customers can choose full turnkey sourcing, partial component supply or provide their own parts. Our team reviews the bill of materials, identifies shortages and confirms approved alternatives with the customer before production moves forward.

What Is Turnkey PCB Assembly Used For?
Turnkey PCB assembly is used when a business wants one supplier to manage the full process, from component sourcing to assembly, inspection and testing. This makes production easier to manage and can reduce delays between different suppliers.
It is often used for new products, repeat orders and low to medium volume production across industrial, medical, automotive, aerospace and defence sectors. Altimex manages each stage to support consistent quality and reliable delivery.
Frequently Asked Questions
What is turnkey PCB assembly?
Turnkey PCB assembly is a complete service covering component sourcing, PCB assembly, inspection and testing. It allows one supplier to manage the project from approved design files through to finished PCB assemblies.
What is included in a turnkey PCB assembly service?
The service can include bill of materials review, component sourcing, surface mount assembly, through-hole assembly, soldering, inspection, testing and final quality checks.
Can Altimex source all the required components?
Yes. Altimex can source components through established suppliers and check part specifications, availability, lead times, compliance and traceability before production begins.
Can I supply my own components?
Yes. Customers can provide all components, supply selected parts or ask Altimex to manage the full sourcing process. This can be agreed during the project review.
Which PCB assembly methods are available?
Altimex supports surface mount technology, through-hole assembly and mixed technology PCB assembly. The production method is selected based on the board design and component types.
Does Altimex support low-volume and repeat production?
Yes. Turnkey PCB assembly can be used for low-volume production, repeat orders, product updates and ongoing manufacturing requirements.
How are finished PCB assemblies checked?
Assemblies are inspected and tested against the agreed project requirements. Checks may include component verification, solder joint inspection, visual inspection and functional testing.
What information is needed for a turnkey PCB assembly quote?
You will usually need to provide Gerber files, a bill of materials, pick-and-place data, assembly drawings, required quantities and any testing requirements. Project timescales should be included where possible.
