Top 10 PCBA Test Suppliers in Luxembourg

Founded in 2005, LuxTest Solutions has grown from a small local lab to a regional leader in PCBA testing, known for its innovative use of artificial intelligence to streamline the pcba testing process. What sets them apart is their ability to handle high-complexity boards—think 10-layer PCBs with thousands of components—with speed and accuracy that traditional methods can't match.

Their service portfolio includes in-circuit testing (ICT), functional testing, and automated optical inspection (AOI), but their crown jewel is their proprietary AI-driven test analytics platform. This tool learns from past test data to predict potential failures, reducing false positives by up to 35% and cutting testing time for high-volume orders by nearly half. "We once had a client in the aerospace industry with a PCB that kept failing functional tests," says Marie Dubois, LuxTest's lead engineer. "Our AI tool flagged a microscopic solder bridge that human inspectors had missed—saving them weeks of rework and ensuring their satellite communication module met launch deadlines."

LuxTest serves clients across aerospace, defense, and industrial automation, holding ISO 9001 and AS9100 certifications to meet strict industry standards. Their team of 45 engineers, many with backgrounds in electronics and software development, works closely with clients to design custom test sequences tailored to each product's unique requirements. For companies prioritizing cutting-edge technology and reliability, LuxTest is a top choice.

EuroPCB Test Labs, based in Esch-sur-Alzette, has built its reputation on one core promise: "If you can design it, we can test it." Since 2010, they've focused on creating custom pcba test systems for clients with unique or highly specialized PCBs, from medical devices with micro-sized components to ruggedized industrial controllers.

Unlike suppliers that rely on off-the-shelf test equipment, EuroPCB designs and builds custom test fixtures in-house, using 3D printing for rapid prototyping and CNC machining for high-precision parts. Their engineering team collaborates with clients from the PCB design phase, providing input on testability (DFT) to ensure that even the most compact boards can be thoroughly inspected. "A client came to us with a PCB for a portable ultrasound machine—so small it fit in the palm of your hand," recalls Tom Schmitz, EuroPCB's founder. "We designed a custom fixture with micro-probes that could access 0.2mm pitch components, something standard fixtures couldn't handle. Now, that PCB is used in hospitals across Europe."

In addition to custom fixtures, EuroPCB offers environmental testing—temperature cycling, humidity resistance, and vibration testing—to simulate real-world conditions. They're particularly strong in the medical device sector, holding ISO 13485 certification, and work with clients like MedTech Luxembourg and Philips Healthcare. For companies with non-standard PCBs that demand tailored solutions, EuroPCB is a go-to partner.

For companies looking for a one-stop shop, Luxembourg Electronics Testing Services (LETS) delivers end-to-end testing solutions, from prototype validation to mass production inspection. Founded in 2012, LETS has positioned itself as a "turnkey" partner, handling everything from test plan development to data analysis and reporting—so clients can focus on design and manufacturing.

This platform combines test execution, data logging, and client portals, allowing customers to monitor test results in real time from anywhere in the world. "A client in Germany once logged in to our portal at 2 AM to check on a batch of PCBs for their smart home devices," says LETS CEO Marco Weber. "They saw that 99.8% passed and approved shipment on the spot—no waiting for morning reports."

LETS serves a diverse range of industries, including consumer electronics, automotive, and IoT, and prides itself on quick turnaround times. Their 10,000 sq. ft. facility in Differdange is equipped with 12 testing stations, including a dedicated line for low-volume prototype testing and a high-speed line for mass production (up to 10,000 PCBs per day). They're ISO 9001 certified and RoHS compliant, ensuring their processes align with global environmental and quality standards.

When it comes to medical devices, there's no room for error. A faulty PCB in a pacemaker or insulin pump can cost lives, which is why Precision Test Luxembourg has carved out a niche as the go-to testing partner for medical electronics companies. Founded in 2010 by a team of ex-medtech engineers, the company combines deep industry knowledge with rigorous testing protocols to ensure PCBs meet the strictest safety standards.

Precision Test's services are tailored to medical applications: they offer biocompatibility testing for PCBs used in implantable devices, EMC testing to ensure compliance with IEC 60601, and functional testing under simulated clinical conditions. Their facility includes a Class 7 cleanroom for handling sensitive components and a specialized lab for testing PCBs in extreme environments (e.g., high humidity for wearable health monitors). "We recently worked on a PCB for a portable ECG machine," explains Dr. Elena Kovac, Precision Test's quality director. "Not only did we test its electrical functionality, but we also subjected it to 1,000 hours of simulated sweat exposure to ensure the components wouldn't corrode—a critical factor for a device worn on the skin."

Certifications are a cornerstone of their business: they hold ISO 13485, ISO 14644 (for cleanroom standards), and FDA registration, making them a trusted partner for companies seeking market approval in Europe and the U.S. Their client list includes major medical device manufacturers like Medtronic and local startups developing next-gen diagnostic tools. For medical PCBs, where precision and compliance are non-negotiable, Precision Test delivers peace of mind.

Electromagnetic interference (EMI) is the silent enemy of electronics. A PCB that works perfectly in the lab might fail in the field due to interference from other devices, making electromagnetic compatibility (EMC) testing a critical step—especially for automotive and industrial electronics. LuxEMC Testing, founded in 2015, specializes in EMC and radio frequency (RF) testing for PCBs, helping clients ensure their products work reliably in noisy electromagnetic environments.

Located in Mamer, LuxEMC's facility features a 10m anechoic chamber—the largest in Luxembourg—equipped with state-of-the-art EMI receivers, signal generators, and antenna systems to test PCBs up to 40 GHz. Their services include radiated emission testing (to ensure the PCB doesn't emit excessive EMI), radiated immunity testing (to check if it can withstand external interference), and electrostatic discharge (ESD) testing. "We had a client in the automotive sector with a PCB for a driver assistance system," says Patrick Meyer, LuxEMC's EMC engineer. "Their initial design failed immunity testing when exposed to the radio frequencies from nearby cars. We helped them redesign the grounding layout and add ferrite beads, bringing the PCB into compliance with CISPR 25 standards."

LuxEMC works with clients in automotive, IoT, and telecommunications, holding ISO 17025 accreditation for their testing methods. They also offer pre-compliance testing, allowing clients to identify EMC issues early in the design phase and avoid costly redesigns later. For companies developing wireless or high-frequency PCBs, LuxEMC's expertise is invaluable.

Not all PCBA testing needs are high-volume. Startups, research labs, and companies developing prototypes often require testing for small batches of highly specialized PCBs—and that's where MicroTest Luxembourg shines. Founded in 2018, MicroTest focuses on low-volume, high-precision testing, catering to clients in robotics, drones, and academic research.

What makes MicroTest unique is their flexibility. They don't require minimum order quantities, making them ideal for prototype testing or small production runs (as low as 10 PCBs). Their services include manual and automated testing, with a focus on quick turnaround—most prototype tests are completed within 48 hours. "We understand that startups need to iterate fast," says CEO Lucas Schmidt. "A client once came to us with a drone flight controller PCB at 3 PM; by 9 AM the next day, we'd completed functional testing, identified a faulty sensor, and provided a detailed report. They had a revised prototype by the end of the week."

MicroTest's team of 15 engineers includes specialists in embedded systems and robotics, allowing them to test not just the PCB itself but also its integration with software. They offer "test as you design" packages, where they work with clients during the prototyping phase to provide feedback on component placement, solder joint reliability, and potential failure points. While they don't handle ultra-high-volume orders, their expertise in complex, low-volume PCBs has made them a favorite among innovators.

For companies with global supply chains, a testing partner that understands international standards is essential.

A great test is only as good as its fixture. Automated Test Systems (ATS) Luxembourg has built its reputation on designing and manufacturing custom pcba test fixtures that make testing faster, more accurate, and repeatable. Founded in 2003, ATS started as a fixture supplier but has since expanded to offer full testing services, combining their fixture expertise with testing execution.

ATS's fixtures are known for their durability and precision. They use advanced materials like carbon fiber and titanium for lightweight, rigid designs, and employ CNC machining and 3D printing to create custom probes and alignment tools. "We once built a fixture for a client with a PCB that had 2,000 test points on a 5cm x 5cm board," says ATS's fixture design lead, Jean Dupont. "The probes had to be spaced 0.2mm apart—something most suppliers said was impossible. Our engineers spent three weeks designing a micro-probe array, and now that fixture is used in their production line, testing 10,000 PCBs per month with zero failures."

In addition to fixtures, ATS offers testing services using their own equipment, including ICT, functional testing, and AOI. They work with clients in automotive, aerospace, and consumer electronics, and their fixtures are exported worldwide—even to companies that handle their own testing in-house. For businesses looking to build their own testing capabilities, ATS's fixtures are a game-changer.
