ICT (In-Circuit Test) fixtures are essential tools used in the electronics manufacturing industry for testing printed circuit boards (PCBs). These fixtures securely hold PCBs in place while conducting electrical tests to verify the functionality of each component and connection. By using pinpoint probes that make contact with test points on the board, ICT fixtures can quickly identify defects such as shorts, opens, or incorrect component values. This precise testing method ensures high-quality, reliable products by catching issues early in the production process, thereby saving time and reducing costs associated with faulty electronics.
ICT test fixture is the abbreviation of InCircuitest test fixture, which is online detection and test fixture. It is a standard test equipment for testing the electrical properties and electrical connections of online components to check manufacturing defects and defective components.
ICT test fixture is mainly used to check the open and short circuit of single online components and each circuit network. It has the characteristics of simple operation, fast and rapid, accurate fault location, etc. ICT test fixture can test the functions of simulators and digital devices logic functions, and has high fault coverage rate. Special needle bed needs to be made for each single board. This needle bed is called ICT test fixture in industrial production.

It is mainly used to check the online single components and the open and short circuit of each circuit network, with simple operation, fast and rapid, accurate fault location and so on.
Features: ICT test fixture is the first test process in production, which can timely reflect the production and manufacturing conditions, so as to use process improvement and promotion. The fault board measured by the ICT test fixture, because of accurate fault location, the maintenance of the fault does not require more professional knowledge, easy maintenance can greatly improve production efficiency and reduce maintenance costs.
ICT test fixture uses program control automation test, simple operation, fast and rapid test, the test time of the board is generally in a few seconds to tens of seconds can be completed. Greatly reduced test time.
