Revolutionizing PCB Testing: RoBAT's Journey from S1 to SCARA
January 7, 2025 | Marcy LaRont, PCB007 MagazineEstimated reading time: 1 minute

From the early days of simple continuity testers to the advanced SCARA machines, RoBAT's evolution in time-domain reflectometer (TDR) and test technology is a testament to the company's commitment to excellence and adaptation in a rapidly changing industry. In this discussion, RoBAT’s Bruce Nockton discusses the journey, challenges, and importance of automating testing solutions, and highlights how RoBAT has become a frontrunner in delivering high-precision testing equipment, setting new standards for the industry.
Marcy LaRont: Bruce, I am struck by what appears to be a culture of continuous innovation at RoBAT. From your first S1 machine to today’s suite of SCARA machines, what strikes you most about that journey and where you find yourselves today?
Bruce Nockton: Looking back, it seems like a long journey from our early S1 machines, which weren’t much more than continuity testers, to the latest TDR machines, but I think the most striking thing for me is how quickly we have had to adapt/develop our test equipment to keep pace with and try to stay ahead of PCB technology. As I mentioned when Pete Starkey visited our facility, we did not initially plan to develop a machine to carry out a fully automatic TDR test of high-speed PCBs.
For many years, RoBAT developed machines for testing assembled backplanes from shorts/continuity/AOI, then X-ray, and more recently, TDR. It was the test results from these machines that really surprised us. Whilst our assembly house customers were happy with the faults we were finding that were created in the process of assembling the PCB, the majority of failures the machines found were caused during the manufacturing process of the PCB. It was at this point we started to explore what high-speed TDR test equipment was available for bare PCBs, only to find it was very limited.

Smart Automation: The Power of Data Integration in Electronics Manufacturing
06/24/2025 | Josh Casper -- Column: Smart AutomationAs EMS companies adopt automation, machine data collection and integration are among the biggest challenges. It’s now commonplace for equipment to collect and output vast amounts of data, sometimes more than a manufacturer knows what to do with. While many OEM equipment vendors offer full-line solutions, most EMS companies still take a vendor-agnostic approach, selecting the equipment companies that best serve their needs rather than a single-vendor solution.

Smart Automation: AI—Revolutionizing Inspection in Electronics Manufacturing
05/27/2025 | Josh Casper -- Column: Smart AutomationArtificial Intelligence (AI) is rapidly becoming a staple in our personal and professional lives. In electronics manufacturing, integrating AI to combat common inefficiencies and to contextualize data will open new doors into how we supplement our traditional processes. In some specific areas of the electronics manufacturing process, integration of AI on the factory floor is already having a tremendous effect. One such area is PCBA inspection, particularly 3D automated optical inspection (AOI) systems.
