In-Circuit Test (ICT) is a powerful tool in the automated testing of PCB. ICT uses the circuit nodes of a board to measure the performance of components regardless if other components are connected to them. Resistance, capacitance, inductance and others, can be measured for components and the connections between them.
Since most PCB problems are due to manufacturing reasons, ICT looks for the typical issues like short circuits, open circuits, and incorrect components. An in-circuit test does not test the functionality of a board, but test many of the components that make up the board.
Advantech has years of experience programming and using state-of-the-art ICT equipment as well as building the fixtures used for testing specific boards. Once fixtures are made and the equipment is programmed, the results provide immediate information that can be used by a range of technicians to quickly check and control design and quality.
In-Circuit Test Benefits Include:
- Automated board testing
- Catch design mistakes
- Catch manufacturing issues
- Easy to interpret test results
