In-Circuit Test Fixtures

Precision In-Circuit Testing Solutions for PCB Assemblies

At DOMUS Automation, we design and manufacture high-precision ICT (In-Circuit Test) Fixtures & Test Program for accurate, repeatable, and high-speed PCB testing in production environments.

Our fixtures ensure reliable electrical contact, long operational life, and stable performance for EMS and OEM manufacturers.

What is an ICT Test Fixture?

An ICT (In-Circuit Test) Fixture is a precision mechanical and electrical interface used to test assembled PCBs. It verifies:

  • Component placement accuracy

  • Open/short circuits

  • Resistor, capacitor, diode values

  • IC functionality

  • Signal integrity

  • Solder joint quality

ICT testing ensures product quality before final assembly or shipment.
