Internally designated Modern Universal Automatic Test Equipment (MUATE-A3480), the test bench is an automatic test equipment (ATE) system and PCBA functional tester that performs automatic measurements on the unit under test (UUT) / device under test (DUT), and evaluates the results against expected values. A computer-controlled system houses multiple complex test instruments capable of automatically testing and diagnosing faults in intricate electronic components, PCBs, and integrated circuits.

As PCB test equipment, it can test a large range of electronic devices and systems — from discrete components like resistors, inductors, and capacitors, to complex compiled electronic systems, modules, and LRUs — harnessing purpose-built JIGs, fixtures, and ITAs (interface test adapters) to reduce the test time needed to verify a particular PCB, component, or LRU.

Five integrated subsystems, one control loop — JTAG, boundary scan, data acquisition, controller, and COTS instruments.

The bench has been used to validate LRUs and modules for front-line aircraft and platform programs, with test-program development and JIG/ fixture engineering carried out in-house at Neometrix's Noida facility.

Test Coverage

Seven checks, one pass/fail call.

Every board that goes through the MUATE-A3480 is run through the same seven-point coverage envelope before it's cleared for deployment.

T · 01Continuity & isolation — verify electrical connectivity and isolation between traces using in-circuit testing (ICT) and flying-probe testing to check for opens and shorts.

T · 02Impedance — match measured impedance of traces and interconnects to design values to prevent signal degradation.

T · 03Power integrity — check PCB operation under different power conditions to avoid errors from insufficient power delivery.

T · 04Signal integrity — examine signal quality under high-speed conditions to prevent distortion and interference.

T · 05Functionality — stimulate the PCB with input signals and power to check outputs match expected responses based on design.

T · 06Robustness — subject the PCB to temperature cycling, vibration, and shock to validate resilience and durability.

T · 07Regression — retest functionality after modifications to ensure no side effects were introduced.
