Full Wafer Level Test
FWLT is a probing technique that tests an entire silicon wafer at once (one touch down) allowing reductions in test time and cost.
Our FWLT Probe Card features a controlled CTE (Coefficient of Thermal Expansion) probe head housing (developed in-house) to operate under a wide temperature range, utilizing our fine pitch, compliant vertical probe pin.
