How to Measure
*1: For the reference value in the table, measure the length of the corresponding position on
the STP3600.

Measurement Item How to Measure
Lead Regi [mm] (P1 to P2) - Reference value *1
Side Regi [mm] (P7 to P8) - Reference value *1
Lead Skew (200 mm) [mm] (P5~P6)-(P3~P4)
Side Skew (400 mm) [mm] (P9~P10)-(P11~P12)
Horizontal R/E Precision (All
area) [%] [(P8~P13)-280]/280X100
Vertical R/E Precision (All area)
[%] [(P2~P14)-400]/400X100
Perpendicularity [mm] The shift between P14 and the perpendicular line that
extends from the intersection of the straight line connect-
ing P4 and P6 and the line A.
Linearity (Vertical) (400 mm)
[mm] The maximum shift between the intersections of the verti-
cal line B with the various horizontal lines and the straight
line connecting P10 and P12.
Linearity (Horizontal) (280 mm)
[mm] The maximum shift between the intersections of the hori-
zontal line C with the various vertical lines and the straight
line connecting P10 and P15.
Linearity (Diagonal) (280 mm)
[mm] The maximum shift between the intersections of the diag-
onal line D with the various lines and the straight line con-
necting P17 and P13, or the maximum shift of the
intersections of the diagonal line E with the various lines
and the straight line connecting P8 and P18, whichever is
larger.
Parallelism [mm] (P10~P12)-(P15~P16)
