Field: Testing and inspection
Probe card in the explanations
A probe card is a fixture used in wafer test, with many needles (probes) arranged to match the layout of the chip's bond pads.
Which correctly describes a probe card?In wafer testing, the many needles of a probe card contact electrode pads arranged around each chip, and the tester applies power and signals and measures the responses.
