Semiconductor refers to the material whose electrical conductivity is between conductor and insulator at normal temperature. Semiconductor products are mainly divided into four categories, including integrated circuits (IC), optoelectronic devices, discrete devices and sensors. ITECH provides comprehensive solutions which are suited for various applications in areas such as packaged IC, semiconductor laser, optoelectronic lighting device, diodes, transistor, FET, thyristor, IGBT, fuse, relay and other discrete device and sensor. Among them, such as IC aging test, power supply test, continuity test of discrete devices, especially semiconductor laser test, relying on IT6000C CC/CV priority setting function and loop speed adjustable function, can effectively suppress boot overshoot.
