The scope and characteristics of ICT online inspection

- Sep 29, 2017-

Check the electrical performance of the online components on the finished board and the connection of the circuit network. It can quantitatively measure devices such as electric resistance, capacitance, inductance, crystal oscillator, etc., and perform functional tests on diodes, triodes, diaphragms, transformers, relays, operational amplifiers, power modules, etc., and perform functional tests on small and medium-sized integrated circuits. Such as all 74 series, Memory class, common driver class, switching class and other IC. It finds defects in manufacturing process and component defects by directly testing the electrical performance of online devices.

The component class can check for the tolerance, failure or damage of the component value, the program error of the Memory class, and the like. For the process class, defects such as solder short circuit, component insertion, plugging, missing, pin lift, solder joint, PCB short circuit, disconnection, etc. can be found. The faults of the test are directly located on specific components, device pins, and network points, and the fault location is accurate. No more professional knowledge is required for the repair of the fault. The program-controlled automated test is simple and quick to test. The test time of the board is usually from a few seconds to several tens of seconds.
