The Electroglas Horizon 4080 X is a wafer prober from Electroglas. The Horizon 4080X supports an optional Bottom Probe Card Changer for rapid changing of probe cards. The Horizon 4080X's Bottom Probe Card Changer provides quick and easy front-loading and unloading of probe cards without undocking the test head.[1][2][3]
What it is
How it works
General reference — not yet source-verifiedWafer probers move a wafer so each die can be brought into alignment with a probe card. The probe pins contact the die pads and route signals between the wafer and the attached test system. Wafer probers generally combine wafer handling, positioning, alignment, and contact sequencing so repeated electrical measurements can be performed across the wafer.
