Rule 107: Planarity Requirements
During probing, non-planarity between the probe contacts and the pads should not exceed 2000 ppm or 0.1°. Non-planarity
can be compensated by using the Cascade Microtech RF positioner; which can be adjusted over ± 3.5°.
Rule 108: Pads at 90° Only
Rows of pads meeting at an angle must be orthogonal (at 90°).
Rule 109: Pads are collinear
All pads contacted by an individual probe must be collinear.
Rule 110: Pads Have Equal Pitch
All pads contacted by an individual probe must have constant pitch or multiples of the constant pitch.
Rule 111: Pads on Top
All probe pads must be on the substrate top.
Multiples of the constant pitch
