DSAB-01C  ABB Diode Module

You can use the evaluation board provided by the manufacturer to verify the operation and performance of semiconductor integrated circuits (LSI and ics). In the product specification and application guide will provide the product test circuit diagram, film (circuit board layout diagram) and precautions, you can refer to.

The use method is: connect the power supply, input signal, control signal, etc., and observe the output signal with an instrument such as oscilloscope or spectrum analyzer. First, check whether the semiconductor integrated circuit (LSI, IC) is working as expected. When the logic is confirmed to work, if it is controlled in parallel, a High signal (H voltage) and a Low signal (L voltage) need to be applied to the control pin. If it is serial control, you need to prepare a separate data generator, etc., create a serial control signal and input. After the basic working condition is confirmed, the next step is to confirm the electrical characteristics. From confirming the main items in the product specification – input and output signals (large signals), to confirming noise levels and crosstalk (small signals), test as needed.

The electrical characteristics of semiconductor integrated circuits (LSI, IC) will show the best value if they are tested through the evaluation board provided by the manufacturer. This value is the value provided in the product specification. That is to say, for the “characteristic performance” in the product (supporting application), refer to the test value of its evaluation board and the standard value in the product specification. On the evaluation board, the negatives of the power and ground wires and the negatives of the input and output signal wires are ideal. Since the wiring, wiring width and wiring length of each wiring have been carefully considered, users can refer to the circuit board when making products (supporting applications).

In addition, because the evaluation board is basically equipped with only one semiconductor integrated circuit (LSI or IC), it can test electrical characteristics in a variety of situations. For example, it can be used to confirm the characteristic change when the supply voltage is changed from the standard voltage (within the recommended operating voltage range), and the characteristic change when the ambient temperature is raised or lowered in the thermostat (be aware of the short circuit caused by frost at low temperatures!). And connecting multiple different evaluation boards to create simple product prototypes.
