Note 1 : To be valid, reported Spec. Limits must not exceed the Spec. Limits of the CMM capability reported in
form IPC-9850-F3.
Note 2: Termination-to-Land evaluation for 1608 components is not required. See Section 3.4.3.2.2 for details.

Note 1: To be valid, reported Spec. Limits in form IPC-9850-F1 must not exceed worse case Spec. Limits of the CMM
capability per component type.
Note 2: Since the CMM utilizes the fiducial markings on all glass slugs, regardless of the specific component image, it is only
necessary to evaluate the CMM’s ability to measure the slugs using the fiducial markings.
