Probe Tip Cleaning Methods
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.

Learn more →Stable contact requires clean probe tips, correct overdrive, accurate planarity, controlled force, and repeatable wafer positioning. Trend data can reveal degradation before it becomes a yield event.
Learn more →Intermittent contact, excessive resistance, pad damage, alignment drift, and temperature instability can create false results. Troubleshooting should separate probe-card, prober, tester, wafer, and recipe causes.
Learn more →A typical flow includes wafer alignment, touchdown, parametric and functional tests, binning, map review, and data transfer. Yield, contact resistance, retest rate, throughput, and false-fail rate are key metrics.
Learn more →Uniform treatment depends on electric-field distribution, gas flow, part spacing, chamber loading, and fixture design. Mapping results across the work area reveals local weak zones before production release.
Learn more →Contact angle and surface-energy measurements provide fast evidence of treatment effectiveness. Consistent liquids, timing, temperature, cleanliness, and measurement locations are needed for useful comparisons.
Learn more →Polymers often need activation without excessive etching, while metals may require oxide or organic removal. Recipe selection should reflect the surface chemistry and the next adhesive, coating, or bonding step.
Learn more →Under-cleaning, over-etching, poor uniformity, redeposition, and surface damage usually point to an unstable recipe, chamber condition, loading pattern, or material mismatch.
Learn more →Oxygen, argon, nitrogen, hydrogen-containing blends, and fluorine chemistry produce different reactions. Gas choice depends on the contamination, substrate, downstream process, and safety requirements.
Learn more →Power, pressure, gas flow, treatment time, and chamber geometry determine cleaning rate and surface impact. These settings should be developed as a connected process window rather than adjusted independently.
