ATNET

Modular, standalone functional test systems that slot into your production line, whoever builds your boards.

Why functional testing?

It is the final quality step in manufacturing, for bare PCBs before delivery and for fully assembled products.

Tested as designed: Tests follow the product specification and intended behaviour, instead of checking components one by one.
High coverage: Goes beyond optical inspection and connectivity checks, and verifies that coupled components actually work together.
Program, configure, calibrate: The natural moment to flash firmware, apply device-specific configuration and calibrate on-board systems before final assembly.
Automated: Frees up operator time and removes the dependence on manual input.
Traceable: Every test run can log more than pass or fail: PCB assembly trace, component IDs, MAC addresses and more.

Who is it for?

Product owners and OEMs

Own quality at the source and catch issues in production before they reach the field. Functional test is also the ideal place to program firmware, apply configuration and provision devices.

EMS providers

Standardize testing across your clients with one flexible architecture. No more setups with poor reliability, repeatability or maintainability. Faults show up sooner, so repairs cost less.

How ATNET is built

Modular

Recurring test functions are interoperable modules that can be swapped for maintenance, recalibration or reuse.

Confined customization

The only product-specific part is a simple, low-cost interconnect PCB. That keeps turnaround, cost and risk down.

WebSocket API

The rig is a server that answers test requests over a fully specified WebSocket interface. A Python client is available and proven in production with NI TestStand.

Fully standalone

All test functions live inside the rig. It is compact, shippable and easy to duplicate when volumes grow.
