What Is Mixed Technology PCB Assembly?

Altimex is a UK electronics manufacturer with more than 30 years of experience in PCB assembly and bespoke electronic production. From its Cheshire facility, the company provides mixed technology PCB assembly for organisations across aerospace, automotive, telecommunications, defence and maritime, supporting projects from early prototypes through to repeat production.

By combining surface mount and through-hole assembly within controlled manufacturing processes, Altimex can produce complex PCB assemblies with consistent quality and traceability. Experienced engineers and technicians oversee each stage of production, helping clients meet technical requirements, manage component sourcing and maintain reliable delivery schedules.

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.

Surface Mount Assembly

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.

Plated Through-Hole Assembly

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.

Combined Assembly Processes

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.

Inspection and Quality Control

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 Mixed Technology PCB Assembly

Altimex provides component sourcing for mixed technology PCB assembly, covering both surface mount and through-hole components within one managed procurement process. We work with established suppliers to source parts that meet the required specification, availability and compliance criteria, with close attention to lead times, component lifecycle and supply risk.

Customers can choose full turnkey sourcing or supply selected components themselves. Our team reviews bills of materials, identifies potential availability issues and assesses suitable alternatives for customer approval. Components are checked before production to support traceability, reduce delays and maintain consistent assembly quality across prototype and repeat builds.

What Is Mixed Technology PCB Assembly Used For?

Mixed technology PCB assembly is used in electronic products that require both surface mount and through-hole components on the same printed circuit board. This method combines compact, high-density circuitry with larger or mechanically secure parts such as connectors, transformers, relays and switches.

Common applications include control systems, communications equipment, LED lighting, medical electronics, industrial machinery, automotive systems, aerospace technology and defence equipment. By selecting the correct assembly method for each component and applying controlled soldering, inspection and testing procedures, Altimex produces reliable PCB assemblies that meet demanding performance, durability and compliance requirements.

Frequently Asked Questions

What is mixed technology PCB assembly?

Mixed technology PCB assembly combines surface mount technology and through-hole assembly on the same printed circuit board. It is used when a design includes compact surface-mounted parts alongside larger components such as connectors, transformers, relays or switches.

What are the benefits of mixed technology PCB assembly?

Mixed technology assembly allows manufacturers to use the most suitable mounting method for each component. Surface mount parts support compact board layouts and automated placement, with through-hole components providing strong mechanical connections for larger or frequently handled parts.

Can Altimex support prototype and production quantities?

Yes. Altimex supports prototype, low-volume and repeat production requirements. The manufacturing process can be planned around the board design, component availability, testing requirements and expected production quantity.

Can Altimex source components for mixed technology assemblies?

Yes. Altimex offers full turnkey and partial component sourcing options. The team can review the bill of materials, source surface mount and through-hole components, identify supply risks and assess possible alternatives for customer approval.

What information is required before PCB assembly can begin?

Customers will usually need to provide Gerber files, a bill of materials, component placement data, assembly drawings and any testing or quality requirements. Clear revision details help maintain traceability throughout production.

How are mixed technology PCB assemblies inspected?

Assemblies can be checked through visual inspection, automated optical inspection and project-specific testing. Inspection requirements are selected according to the board layout, component types, production quantity and intended application.

Which industries use mixed technology PCB assembly?

Mixed technology assemblies are used across aerospace, automotive, defence, telecommunications, maritime, industrial control, medical electronics and LED lighting. They are common in products that need compact circuitry combined with durable connectors or larger components.

Are mixed technology assemblies completed to IPC standards?

Altimex uses controlled assembly practices aligned with recognised standards, including IPC-A-610 and IPC-J-STD-001. Project requirements should be discussed at the quotation stage so the correct workmanship, inspection and documentation criteria can be agreed.

How long does mixed technology PCB assembly take?

Lead times depend on board complexity, component availability, production quantity, inspection requirements and testing needs. Altimex reviews these factors before production and provides a realistic schedule based on the project specification.
