The DUT side tip design accurately maintains its 100 \u00b5m spacing for the life of the probe. Customers report typical probe life of 500 k to 800 k package insertions, or over 2M touchdowns at wafer-level test. The offset tip allows manageable board layout with a board-side spacing of 0.4 mm.<\/p>\n<div  class='avia-button-wrap av-18a7y4-308ee268d1c35757d79153495d048738-wrap avia-button-left
