Recommended Offline Cleaning Methods and Materials
Brush Cleaning
Refer to the Cascade Microtech Application Note, Pyramid Probe Core Off-line Cleaning With a Brush for a complete
brush-cleaning procedure.
Abrasive Cleaning
Extreme resistive-buildup contamination can be removed by abrasively cleaning the probe tips. This cleaning process is
identical to the online process described above, except that the number of touchdowns is higher.
In most cases resistive tips can be cleaned up with only 150-200 touchdowns on the cleaning film. However, sometimes
more aggressive cleaning is required. In these instances, up to 1000 touchdowns may be necessary to remove the
contamination. Accumulation of contamination this tenacious usually indicates other problems in the probing environment.
High current, residue on bond pads, insufficient online cleaning, and hot probing (making or breaking contact with power
applied) can all contribute to abnormal accumulation of resistive films on Pyramid Probe tips.
Service
