(B02_14) Electd Size Detn/Electd Size Tol [mm]
Select whether or not the Electrical Contact Size Judgement is per-
formed. If it is, select the allowance from the following options.
Disable : Select this when the electrode size determination
is not to be made.
Enable (Auto) : Select this when the electrode size determination
should be made. The automatically set default
value is used for the electrode size tolerance.
Enable (Mnl) : Select this when the electrode size determination
should be made. The arbitrary set value is used
for the electrode size tolerance.
Unit: mm
Data Input Range: 0 to 9.999
(a) Select this only when the "Manual" is set in the "Recognition data set"
data box.
(b) When "Enable (Auto)" is set in the "Electd size detn" text box, the
value indicated in the "Electd size tol [mm]" text box is used.

(B02_16) Polarity detn Data
Set the determination way for the component polarity (direction).
Fig. B208 Edit Window (Example)
Applicable Components : BGA/CSP
(1) Polarity detn
Select one of the following options to ascertain whether or not the
polarity determination function should be implemented.
Disable : Select when the polarity determination function is
not implemented.
Enable (Discard) : Select when the polarity has been checked and
found to be different, and is to be determined as
an error.
Enable (Placement) : Select when the recognition function is re-performed
according to the determined polarity after the po-
larity is checked and determined.

(a) When "Enable (Placement)" is selected, the recognition processing
time becomes twice or more than usual.
(b) When it is required to check whether or not a component has a polar-
ity (when components are not fed in the specified direction), "Enable
(Discard)" or "Enable (Placement)" must be set in the text box. The
machine performs the recognition operation after checking the polar-
ity.
(c) The following requirements must be met when "Enable (Discard)" or
"Enable (Placement)" is selected.
• With BGA/CSP components, the center of the ball grid should agree
with the center of the mold.

(2) Inspection method
Select one of the following options for the number of points to be in-
spected for polarity determination.
4-Point Insp : Inspect four points which overlap when each mold is
turned to an angle of 90
°, using the center of the mold
as the reference.
Select when the mold shape is square.
2-Point Insp : Inspect two points which are positioned diagonally when
the mold is turned through 180
°, using the center of
the mold as reference.
Select when the mold shape is rectangular.
