Teradyne has introduced Omnyx Edge, an automated inline testing platform for complex printed circuit board assemblies used in robotics, industrial computing, automotive electronics, and other equipment incorporating edge artificial intelligence.
The system extends Teradyne's existing Omnyx product family beyond data centre hardware, providing a combination of in-circuit testing, boundary scan, device programming, contactless power-stage measurements, and optical inspection of onboard LEDs.
Omnyx Edge targets three broad categories of assembly: computing boards containing processors and associated memory, sensing boards carrying measurement and interface electronics, and motion-control boards incorporating power converters, motor drivers, and actuator circuitry.
These assemblies frequently combine dense electronic packaging with limited access to individual connections. High component counts, fine-pitch devices, and multilayer PCB routing can make it difficult to inspect or test every relevant circuit using conventional physical probes.
Automated in-circuit testing uses electrical access points to investigate the characteristics of components and interconnections on a populated board. Depending on the test arrangement, measurements can identify incorrect component values, open circuits, short circuits, and other assembly defects.
The technique requires a suitable fixture and access to the electrical nodes being measured. As board density increases, the number of accessible test points may become restricted, particularly beneath advanced integrated circuit packages or within tightly arranged processing modules.
Teradyne addresses part of this constraint by integrating boundary scan. The technique uses test circuitry incorporated into compatible semiconductor devices to observe or control selected connections without requiring an external probe on every relevant signal.
Boundary scan can extend interconnect fault coverage where direct probing is impractical. Its usefulness depends on the installed devices, their supported test functions, and whether the board design provides the necessary test access and interconnection arrangements.
It does not replace every analogue or functional test. Power rails, passive components, and other circuits may still require conventional electrical measurements, while some faults only become apparent when the completed assembly is operated under representative conditions.
Omnyx Edge combines these methods within a common test environment. Its updated system controller also supports device programming, including integration with compatible third-party programming tools.
Programming devices during board test can reduce the number of separate manufacturing operations, provided the programming process can be incorporated into the inspection sequence without introducing unacceptable cycle time or production constraints.
PowerSense provides a further testing option for assemblies containing switching power electronics. The technology uses contactless sensing of pulse-width modulation behaviour to assess suitable DC-DC converters and power stages supplying processors, controllers, or electric motors.
Switching converters regulate electrical power by repeatedly turning semiconductor devices on and off. Their switching frequency, duty cycle, and timing influence the energy transferred through the converter and the resulting voltage or current supplied to the load.
Examining the relevant PWM behaviour can help determine whether a power stage is operating in accordance with its expected control pattern. The result must be interpreted alongside the converter architecture and the test limits established for the specific assembly.
Contactless sensing is useful where attaching a probe directly to a switching node would be difficult or undesirable. However, PowerSense does not make the entire board test contactless, and its ability to detect a particular fault depends on the electrical behaviour available for measurement.
For boards containing indicators or other light-emitting devices, Teradyne has added LEDSense. This optical testing function can check supported LEDs within the production fixture, extending inspection beyond the electrical measurements used to determine whether the associated driving circuit is connected correctly.
An LED may receive the expected electrical drive while failing to produce the intended optical output. Optical measurement can identify certain faults that would not necessarily be established through an electrical test of the driver alone.
The required inspection method depends on the function of the lighting device. A status indicator may require a presence check, while equipment using illumination as part of a sensing or communications function can require more detailed optical verification.
Three Omnyx Edge configurations address different board complexity and production requirements. The Edge 25 provides approximately 2,500 test pins in a single-site arrangement, while the Edge 50 offers around 5,000 pins divided between two test sites.
The larger Edge 65 provides approximately 6,500 test pins in a single-site configuration. Test capacity determines the number of available electrical connections, but the required configuration also depends on the fixture, measurement sequence, and structure of the board being inspected.
Multiple test sites can allow more than one assembly to be processed within the equipment, subject to the selected configuration and production workflow. The resulting throughput depends on the duration of the test programmes and the time required to move boards into and out of position.
Teradyne specifies a maximum supported PCB footprint of 530 × 508mm and a board weight of up to 5kg. The equipment is also compatible with existing TSH and TSHL fixtures, providing a potential migration route for manufacturers with suitable tooling already in use.
Automated handling is supported through a programmable logic controller, touchscreen human-machine interface, and SMEMA-ready conveyance. These functions allow the tester to exchange boards with compatible assembly-line equipment rather than requiring a separate manual loading operation for every inspection cycle.
Integration with production handling systems must account for board orientation, transfer timing, fixture loading, and the response to unsuccessful tests. A tester's electrical capacity alone does not establish the number of assemblies a production line can inspect per hour.
The platform also incorporates AI-based preventive maintenance functions intended to monitor equipment condition and reduce interruptions. Teradyne has not disclosed measured improvements in equipment availability, yield, or production throughput attributable to these functions.
Omnyx Edge will be demonstrated at electronica 2026 in Munich from 10 to 13 November, including PowerSense, boundary scan, and automated line integration. The manufacturer has published the principal system configurations and technical limits but has not disclosed pricing, initial shipment volumes, or customer production results.
