Electronics Repair and Testing Services in Ireland
RTR Electronics’ electronics repair and testing services help you get more life out of the boards and assemblies you already own. Our electronics repair technicians in Limerick diagnose faults, remanufacture worn or field-returned units, and functionally test every board before it goes back, supporting medical, automotive, aerospace and industrial customers under our ISO 9001:2015 system.
Services We Offer

Functional Testing & Quality Assurance
Failure Analysis
Advanced Testing Capabilities
Our state-of-the-art testing facilities ensure that each repaired or remanufactured electronic component meets the highest standards of quality, safety, and performance. We use rigorous testing protocols to validate reliability, helping our clients maintain optimal functionality across various applications. Our advanced testing capabilities include:
Electrical Testing & Signal Integrity
Our electrical testing services evaluate the performance of circuits and components under operational and maximum load conditions. We focus on parameters such as current leakage, voltage stability, and signal integrity, confirming that each device performs reliably without electrical interference or degradation in signal quality.
Performance Benchmarking
Our performance benchmarking tests measure the repaired or remanufactured components against industry and manufacturer specifications. We assess key metrics such as response time, processing power, and overall efficiency, ensuring that each component can perform as expected under actual use cases. This provides peace of mind that components are fully optimized and reliable.
Burn-In Testing
Burn-in testing subjects components to elevated temperatures and voltages over an extended period, identifying early-life failures and ensuring long-term reliability. By replicating prolonged operational stress, we catch potential weaknesses in components that might only surface after continuous use, enhancing durability and customer satisfaction.
Functional and End-of-Line Testing
Every repaired or remanufactured component undergoes functional testing to ensure that it operates correctly within its intended application. Our end-of-line testing protocols confirm that all repaired units are fully operational, verifying functionality before they leave our facility. This comprehensive approach minimizes field failures and guarantees that each component is ready for immediate deployment.
X-Ray and Imaging Inspection
For critical components like BGAs (Ball Grid Arrays) and other high-density interconnections, we use X-ray inspection to check for solder joint integrity, hidden defects, and structural anomalies. This non-destructive testing method allows us to identify hidden issues that might affect component performance or reliability, particularly valuable for high-complexity electronics.
Automated Optical Inspection (AOI)
Our Automated Optical Inspection system captures high-resolution images of repaired or remanufactured PCBs and uses advanced algorithms to detect even the smallest inconsistencies. AOI helps us catch potential errors or defects early in the process, ensuring each board is in top condition.
Failure Analysis and Root Cause Investigation
In cases where components have recurrent issues, we conduct a detailed failure analysis to identify the root cause. This involves a systematic examination, including thermal and mechanical stress testing, to determine why a failure occurred. Our findings often provide insights for design improvements and future preventive measures.
What We Repair and Test
Our electronics repair work covers assembly and board level, not just single components. Typical jobs that come through our Limerick workshop include:
- Complete PCBs and populated assemblies
- Sub-assemblies and modules pulled from larger systems
- Field-return units sent back by your customers
- Obsolete board remanufacturing, where the original is no longer available
- In-circuit and functional testing to confirm a board genuinely works
- Environmental and burn-in testing on request
Every repair is diagnosed, documented and in-circuit tested before it leaves us, so you know exactly what was wrong and what we did about it.
How We Differ From Simple Rework
Swapping a single part is rework. Our electronics repair and testing services go a step further: we take in a unit that has failed, find the root cause, remanufacture whatever needs replacing, and prove the whole board works before it ships. That full diagnose-repair-test loop is the difference between a board that limps along and one you can trust back in the field.
Industries We Repair For
We repair and remanufacture for the same regulated sectors we build for, including medical device, industrial electronics and automotive customers across Ireland, the UK and Europe.
Our Electronics Repair and Testing Process
Every job follows the same straightforward path, so you always know where your boards are:
- Intake and diagnosis — we log the unit, recreate the fault where we can, and trace it back to a root cause rather than guessing.
- Remanufacture — we replace failed parts, repair damaged tracks and pads, and bring the board back to a known-good state.
- Functional and in-circuit testing — we power the board up and test it the way it is actually used, not just visually.
- Reporting and return — you get the board back with a clear record of what failed and what we did about it.
It is the same disciplined flow whether you send us a single board or a tray of field returns.
Documentation, Traceability and Quality
Because so many of our customers work in regulated industries, our electronics repair and testing services run under an ISO 9001:2015 quality system. Each repair can be documented and traced, from the fault we found through to the parts we fitted and the tests the board passed. If you need a repair report for your own records or for your end customer, we can return one with the unit.
Turnaround and Low-Volume Support
Not every electronics repair job is a big batch. We are happy to take on a single high-value board, an ongoing trickle of field returns, or a short run of obsolete boards that you simply cannot buy new any more. Where a product has reached end of life, remanufacturing and testing the stock you already have is usually far cheaper than a redesign, and it keeps your equipment in service while you plan a longer-term replacement.
Why Choose RTR for Electronics Repair and Testing
We are the same Limerick team that assembles and builds electronics from scratch, so a board we repair is handled by people who understand how it was put together in the first place. You deal directly with the engineers doing the work, there is no offshore handover, and everything stays inside the EU. For Irish and UK customers that means quicker turnaround, easier conversations and full visibility of what is happening to your hardware.
Frequently Asked Questions
Can you repair field-return boards from end users?
Yes. We regularly take in units that have failed out in the field, diagnose what went wrong and remanufacture them so they can go back into service.
Do you provide repair reports with each unit?
What test equipment do you use?
Can you handle low-volume obsolete board remanufacture?
If you have boards stacking up that are too valuable to scrap, our electronics repair and testing services are an easy place to start. Talk to our Limerick team about a diagnosis and a quote.
