| titleOfInvention | Calculator chip inspection device |
| abstract | The inspection device of the conventional calculator chip is the inspection device of the general chip, which is equipped with all the functions of the inspection device, which is expensive, and requires much manpower and time for its maintenance. There is a disadvantage of lowering productivity. Accordingly, the present invention provides a control unit for outputting a mode control signal and comparing all detected values to a reference value stored therein, and performing a non-payment determination of an input value, an output buffer unit connected to the control unit to temporarily store an output value of the control unit; A decoder connected to the control unit for decoding the edge signal of the control unit, an output port expansion unit connected to the output buffer unit, a signal converter for converting an analog signal into a digital signal or a digital signal into an analog signal, and a signal converter And a power supply and current measurement unit connected to the calculator chip to supply power voltage to the calculator chip and detecting the output current signal of the calculator chip, and a key simulator unit connected to the output port extension unit to input a key code to the calculator chip. A level comparator connected to the calculator chip for detecting the level of the output signal of the calculator chip, and a decoder section A frequency measuring unit connected to the decoder and the clock generator and the level comparator to determine the frequency of the output signal of the calculator chip, and connected to the decoder and the calculator chip to detect the output waveform of the calculator chip. An input port extension unit connected to an output waveform detector, a signal converter, a frequency measuring unit, and an output waveform detector to input values input to the controller, and an input buffer connected to the input port extension unit to temporarily store input values of the controller It consists of a part and a tower needle interface connected to the output port extension part.It is a function that inspects only the calculator chip among all the functions provided by the general inspection device, that is, the DC measurement unit which measures the current consumption and each output waveform when the function of the calculator is operated. It consists of a functional inspection section that determines whether a function is normal by measuring it, reducing inspection costs. Also reduced by the size of four plant relates to an inspection system for a calculator chip solve the conventional disadvantages. |
