Automotive Electronics Manufacturing in Ireland
RTR Electronics partners with automotive innovators on the electronics behind ADAS, infotainment, electric vehicle and powertrain platforms. From our ISO 9001:2015 facility in Limerick, we deliver PCB assembly, cable harness assembly and box build that meets the durability, traceability and quality expectations of automotive OEMs and tier-1 suppliers.
Key Services for the Automotive Sector:
Precision PCB Assembly: Our PCB assemblies are crafted to withstand the challenging conditions in automotive environments, including exposure to extreme temperatures, vibrations, and humidity.
Prototyping and Testing: We provide comprehensive prototyping and testing to ensure each component meets automotive-grade requirements before entering full production.
Advanced Cable Harness Assembly: Our custom cable harness solutions support the complex electrical systems within modern vehicles, ensuring reliable connectivity and efficient performance.
Electronics Repair and Remanufacturing: We extend the lifecycle of automotive electronics through expert repair and remanufacturing services, helping reduce costs and promote sustainability.

Automotive Capabilities
Automotive electronics have to work first time, every time, often in tough conditions. Our build covers:
- Automotive-grade SMT and through-hole PCB assembly
- Conformal coating for under-bonnet heat, vibration and moisture
- Cable harness assembly for in-vehicle wiring
- Box build of complete electronic modules
- Functional and burn-in testing
- IPC-A-610 Class 2/3 workmanship and full lot traceability on request
ADAS, EV and Powertrain Electronics
From driver-assistance sensors and infotainment boards to battery-management and powertrain control electronics, modern vehicles carry more electronics than ever. We help automotive OEMs and tier-1 suppliers move these designs from prototype into reliable production, with the documentation and repeatability the sector demands. Whether it is a low-volume ADAS pilot or a steady EV sub-assembly run, the same Limerick team handles your build end to end.
Quality Standards for Automotive Work
Every assembly is built under our ISO 9001:2015 quality system and inspected to IATF 16949 and IPC-A-610 expectations where your programme requires it. We maintain full lot traceability and can meet customer-specific process and documentation requirements, so your automotive electronics arrive audit-ready.
Why Automotive Customers Choose RTR
Automotive programmes live or die on consistency, so our customers value the fact that the same Limerick team builds every batch under one quality system. You deal directly with the engineers on the line, design and traceability data stay in one place, and there is no offshore handover to introduce variation between runs. For OEMs and tier-1 suppliers serving the Irish, UK and EU markets, that means shorter feedback loops, faster corrective action and electronics you can defend in an audit. Whether you are validating a new automotive electronics design or holding a proven product in steady production, you get a partner who treats your programme as a long-term relationship rather than a single purchase order. That continuity is exactly what keeps automotive electronics reliable from the first prototype to the ten-thousandth unit.
