What Are Multilayer PCBs?
Multilayer PCBs are printed circuit boards made up of three or more conductive layers, stacked and separated by insulating materials. These boards allow for more complex circuit designs in compact spaces, making them ideal for modern electronics where high performance and smaller form factors are essential.
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.

Where Are Multilayer PCBs Used?
Multilayer PCBs are used in a wide range of high-performance and compact applications, including:
Telecommunications – Routers, network switches, and signal processing equipment.
Medical Devices – Imaging systems, monitoring devices, and diagnostic tools.
Aerospace & Defence – Navigation systems, radar, avionics, and communications.
Industrial Automation – High-speed control units and embedded systems.
Consumer Electronics – Smartphones, tablets, and wearable tech.
Sectors we support.
Electronics manufacturing for applications where quality, reliability and consistent performance matter.
What Design Considerations Are Involved?
Designing multilayer PCBs requires careful attention to:
Signal Integrity – Stack-up and trace layout must support high-speed data without distortion.
Thermal Management – Heat dissipation must be factored in for dense or high-power circuits.
Manufacturability – Via types, drill tolerances, and material compatibility are reviewed to avoid production delays.
Cost Balance – Optimising layer count without compromising performance.
Altimex can review your design to identify any issues before production.

Frequently Asked Questions
Yes, Altimex offers design support. Whether you need help finalising a layout or reviewing it for manufacturing feasibility, the engineering team can assist.
Yes. Altimex can supply fully assembled PCBs, including both surface-mount and through-hole components. They also offer testing and inspection as part of the service.
Lead times depend on the complexity of the board and whether assembly is required. Simple bare boards can be produced in as little as 5–10 working days, with assembled boards typically taking longer.
No, Altimex accepts low-volume and prototype orders without a minimum quantity requirement.
Altimex supplies custom PCBs for industrial automation, medical devices, aerospace, defence, telecoms, automotive systems, and more.
Yes. All PCBs can be manufactured in accordance with RoHS (Restriction of Hazardous Substances) directives upon request.
