Note 1: A0, B0, and K0 are determined by component size. The clearance between the components and the cavity must be
within 0.05 mm min. to 0.5 mm max. The component cannot rote more than 10o within the determined cavity.
Note 2: If B1 exceeds 4.2 mm(0.165'') for 8 mm embossed tape, the tape may not feed through all tape feeders.
