摘要： A probe card is provided. The probe card can serialize, analogize and divide a digital signal by a analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a power divided unit respectively. The probe card can increase signal channels, and is not restricted by signal channels of a tester to test more DUTs simultaneously. Moreover, the probe card has fine impedance matching and channels separating to raise testing efficiency and reduce signal loss.
