QUALITY CONTROL

Description: Functional test refers to various necessary logic or signal state tests under specific working conditions (that is, the normal use environment of the device, usually at room temperature) and the normal working state of the device. This test is based on the original factory specifications and industry standards or specifications, and designs a feasibility test vector or a special test circuit, applies a corresponding signal source input to the test sample, and analyzes specific conditions such as the adjustment control of the peripheral circuit, signal amplification, or conversion matching. The logical relationship of the signal and the change state of the output waveform are used to detect the functional characteristics of the device.

Applications: Critical functional verification of all semiconductor devices.
