Learn more →Alignment and planarity determine whether probes contact the intended pad locations with balanced force. Optical inspection, scrub-mark review, and metrology help identify bent, worn, or shifted probes.
Learn more →Probe tips collect oxide, metal transfer, and organic residue during testing. Cleaning method, media, force, frequency, and validation must match the probe technology and pad metallurgy.
