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.
