• Sheet Layout

When the [Control Data] tab is pressed, the "Control Data" tab

sheet will appear.

••

• Sheet Composition

This tab sheet is used for indication or entry of each data.

Refer to "4.1 Basic Operations" in "Section 2" (the instruc-

tion manual (Vol. 3) of the main machine) for the detaild

information on how to enter parameters.

*1 V. bend DETN

Mode

V. bend detection function is set.

Enable : V. bend detection function is used.

Disable : V. bend detection function is not used.

Retry

The retry function is set.

The retry function is to detect a V. bend again, with a different

setting; this when the height for scanning is deviated or the

detection result is NG (no good), due to incorrect setting in V.

bend detection operation.

Lead coplanarity tol [mm]

The tolerance of the height deviation for the Iead is set. If the

V. bend is larger than the set value, it is judged as NG (no

good).

Error process

This function is set so that, after the V. bend detection shows

NG continuously, then the machine should be stopped due to

the error.

Data Setting Range: 1 to 9

1 : When NG occurs once in V. bend detection, the ma-

chine is stopped.

2 : When NG continuously occurs twice, the machine is

stopped.

n : When NG continuously occurs "n" times, the machine

is stopped.

Data set

Auto : Detailed settings are automatically performed.

Manual : Detailed settings can be performed manually.

*2 Items for Detailed Setting

When the V. bend detection data setting is set to "Manual", the

detailed setting items will be displayed.

Slant virtual plane detn

Disable (Default) :

The virtual plane inclination is not to be decided on the basis

of the heights of all leads.

Enable (Manual) :

The virtual plane inclination is to be decided manually on the

basis of the heights of all leads.

Slant virtual plane allowance

This is displayed when the slant virtual plane detection is set to

"Enable (Manual)". Enter the slant virtual plane allowance value.

When "0" is set, the slant virtual plane detection will

not be decided.

Accuracy

Auto (Default) :

The measurement accuracy (standard/high accuracy) is

automatically set, based on the component data.

Standard :

The test is performed at standard-resolution level.

SOP, QFP, Connector:

This is set when the lead pitch is 0.4 mm or more.

BGA, CSP :

This is set when the ball pitch is 0.8 mm or more and the

ball diameter is 0.5 mm or more.

High accuracy :

The test is performed at high-resolution level.

SOP, QFP, Connector :

This is set when the lead pitch is less than 0.4 mm.

BGA, CSP :

This is set when the ball pitch is less than 0.8 mm and

the ball diameter is less than 0.5 mm.

Luster condition

Auto (Default) :

The component characteristics (lead luster degree) are set

automatically. In the case of leaded components, the half-

luster lead is set. In the case of BGA and CSP, the luster

ball is selected.

Luster :

The component characteristics (lead or ball luster degree)

are set to "Luster". In the case of leaded component, when

the surface is palladium- or gold-plated, the lead is strongly

reflected, set it to "Luster". In the case of the ball, "Luster"

is usually set.

Half-luster :

The component characteristics (lead luster degree) are set

to "Half-luster". With a general leaded component, set it to

"Half-luster".

Non-luster :

The component characteristics (lead or ball luster degree)

are set to "Non-luster". When the lead or ball is not a

reflected component, set it to "Non-luster".
