Probe Contact Force and Resistance Measurement

The customers are required to provide the following information:

• PA file (must include: ID, probe coordinates, and pin assignment)
• Desired probe downward pressure for measurement
• Design value for probe probe contact force
• Type of probe (cantilever, vertical, etc.)
• Measurement method (equal OD downforce or downforce based on a common plane with four corners as reference)
• Number of probes to be measured (full inspection or specific probe check)

Measurement limitations:

• The pitch value should be 20 or above
• Probe contact force should be 14g or below
• The maximum allowable probe height difference is 60 um

Estimated working days:

• Depending on the scale of the probe, the estimated working days range from 2 to 4 days.
