The over $1.2M order includes a FOX-CP System configured with 2,048 independent universal test resources, multiple proprietary high-power WaferPak contactors and an integrated high power and fully automated high force chuck wafer prober. The shipment is expected during Q2.
The testing is carried out using an equipment called a wafer prober or handler.
Generally, hundreds or thousands of probe needles are assembled into an array on a device called a probe card, which is tailored to interface between the specific type of IC being tested and the wafer prober. During testing, precise needle geometry is essential to ensure test data reliability and consistency for several reasons:
In the latter case, the instruments are integrated with a wafer prober. For high-efficiency testing on multiple DUTs, a switching matrix would also be part of an integrated test system.
"For an AX-Series [system], we typically use hard docking to a wafer prober or IC handler, just as conventional ATE would."
The system consists of a network analyzer, wafer prober, two power supplies and a computer.
Just as tester manufacturers have defined an interface to the probe card, so too, wafer prober companies have specified the interface between the probe card and the prober.
