Advanced product testers and LabVIEW solutions

We build advanced testers for PCBAs and electro-mechanical products, on high-performance controllers for tasks too fast and too complex for a regular PLC. Our LabVIEW solutions, advice and courses back them up.

What we do best

Advanced product testers

Fast, cost-effective test systems for PCBAs and electro-mechanical products. Our high-performance testers handle high-speed, complex and parallel tasks where standard PLCs are not fast or strong enough. We design the hardware, fixtures and software in-house.

Advanced LabVIEW solutions

Complex LabVIEW systems on various architectures: real-time, FPGA and desktop. We also review code, advise developers, teach LabVIEW and give expert opinions, for example for court cases.

    Hands-on training and guidance, from good habits to advanced architectures.

Case studies

isolated from the network

Marshalling yard control system

A control system for safety-critical railway infrastructure, built as a standalone hardware solution with no connection to any network.

  • Several high-performance controllers run a real-time operating system, backed by an FPGA unit.
  • Network isolation removes remote access as an attack path.
  • High-speed dataloggers record events, so any problem can be diagnosed afterwards.

−20+20+40 −20 °C +40 °C

Thermo-regulation for a leading industrial partner

A compact environmental test system that simulates temperatures from −20 °C to +40 °C, developed for a global leader in climate and energy technology. Very small, complex electronics and actuators let us fit several independent chambers into the size of a briefcase.

  • Solid-state Peltier heating and cooling means no compressor and no refrigerant.
  • A custom controller, heat exchanger and custom sensors regulate the whole range.
  • All electronics and mechanics are custom-made, so the solution fits the product, not the other way round.

Electronics and PCBA testers

Fast, cost-effective testers for electronics, manufactured by us for leading companies in Austria and Slovenia. A few hundred tests run in a few seconds.

  • Short test time lowers the cost of testing each board.
  • Advanced function tests capture signals in the gigasample range to measure phenomena lasting only a few nanoseconds.
  • Faults that ordinary testers miss show up before the product ships.

Camshaft sensor tester

An end-of-line tester for an automotive camshaft sensor, built for an industrial partner. The in-circuit and the functional test are merged into one station and finish in about 10 seconds.

  • Resistance, capacitance and inductance, then a functional test with a rotating magnet, all from one contact.
  • Signal edges around 100 ns and switching angles measured against a high-precision encoder with 40,000 positions per turn.
  • Each part is checked in the ERP system first, and the results are stored and sent to the server.

Programming and test stations

A family of compact benchtop stations for appliance control boards: they flash the firmware, test the relays and the power, and print the label. One LabVIEW application runs them all.

  • Single and dual socket programmers, with a relay and power tester for the finished board.
  • Safety circuit with emergency stop, and two user levels: operators test, administrators manage recipes.
  • Every board is recorded, and a new product needs a recipe, not new software.

Computer vision inspection

Universal inspection software that the user configures for a particular part, whether a PCBA or an electro-mechanical product. Used by partners in PCBA manufacturing, LED lighting manufacturing and the automotive sector.

  • One configurable software solution covers many different parts.
  • A 24 MP camera inspects fine details on the part.
  • Repeatable, automated inspection takes the place of slow visual checks.

Railway trackside electronics

Electronics for railway trackside systems: we service and renew rockfall and landslide detection, and we keep old systems running when their sensors are no longer made.

  • We service older Slovenian and French rockfall and landslide detection systems across Europe. Our new generation has improved noise immunity, signal stability and detection precision.
  • Our own electronics connect modern sensors from proven manufacturers, such as Frauscher RSR180, ALTPRO ZK 24-2 FM and Honeywell, to old systems whose original sensors are no longer available.
  • It replaces the discontinued GAT electronic railway switch, and it is approved for use on railways in the EU.

Why work with us

Experience across industries

Over the years we have developed for partners all around the globe, from heating to automotive, aerospace and railway. Versarum is run by its founder, a certified programmer and developer, and takes on larger projects together with trusted partner companies.

We keep improving a solution until the customer is more than impressed, and every challenge adds to what we know. The higher the challenge, the greater the passion.

The right technology for the job

We choose the technology that fits the task. Sometimes that’s a multi-core processor, an FPGA or a real-time system. Sometimes it’s a simple, well-proven design with very few bugs, which is exactly what a robust product needs.

A customer once asked for a datalogger that records events in the microsecond range. We built one in nanoseconds, and they called it nonsense. A year later they phoned to say thank you: without it, they could not have diagnosed their problem.

About

Mitja Gliha, founder of Versarum

Mitja Gliha

Founder and head of R&D

I build the electronics and software that test, control and protect real systems. I founded Versarum in 2013 and run it myself, with trusted partner companies on the larger projects.

I studied electronics at the Faculty of Electrical Engineering, University of Ljubljana, and started with LabVIEW as a student researcher in the biocybernetics laboratory. I was an NI LabVIEW Student Ambassador for Slovenia and Croatia, teaching students and engineers, and an applications engineering intern at NI in Budapest, supporting customers in the region.

Recent work includes a full control system for a hump marshalling yard with hot-swap redundancy, a universal PCBA tester that runs hundreds of measurements in seconds, a Peltier thermal simulator that reaches −20 °C, and a 1960s rockfall-detection transmitter repaired and back on the track in five days.

I am an NI Certified Professional Instructor and LabVIEW developer. If standard PLCs and off-the-shelf testers cannot solve your testing, control or legacy-electronics problem, send me a message.
