Pulse waveforms can be output freely!! Measured waveforms are beautifully reproduced on the monitor!!

- Editing and rearranging inspection steps is possible on the PC monitor. - Inspections combining different pulse output waveform patterns and power voltages can be performed. - Arbitrary pulse waveforms can be output. - A dedicated measuring device is used for thermal resistance, ensuring high precision (communicates with the thermal resistance meter via GPIB). - All inspection results can be saved in a log file. - Measurement waveforms can be viewed on the PC monitor. - Since it uses a Windows PC, the operation is easy to understand. - Simultaneous measurement on 2 channels is possible, allowing for judgment based on the interrelationship of the measurement waveforms.

basic information

◎Overview The device is a performance inspection machine for substrates. The substrates to be inspected drive the IGBT with an input signal and switch a 10A power supply. Each inspection involves verifying the operation of the IGBT based on the voltage of the input signal and measuring thermal resistance. The conditions for each inspection are set using a DA and PIO board built into a PC, and the voltage waveforms are determined using an AD board. The inspection software is an application running on a Windows PC, making modifications and changes easy. ◎Configuration ■PC - OS: Windows XP - AD: 12bit 16ch 10μs sampling - DA: 12bit 4ch 10μs sampling - PIO: 32 output points, 32 input points ■Inspection Machine Body - Power supply (0~20V) output: 1 point - Pulse (0~5V): 1 point - Voltage measurement input (±10V): 6 points ■Jigs - Work detection sensor - Press detection sensor - OK/NG stamping ■Thermal Resistance Meter ■DC Power Supply (20V 18A)
