Dispense parameters
64523-N7-00
A: Required Nozzle
Select the nozzle to be used for dispense.
B: Dispense Nozzle
Select the nozzle type from "1 SHOT Type" or "2 SHOT Type".
C: Dispense Unit
Set the quantity of adhesive to be dispensed.
D, E: Ref. Pos. X (mm), Ref. Pos Y (mm)
In the case of bond type adhesive, set the deviation between the center of dispense and that of the component.
In the case of solder type adhesive, set the offset from the outer line of the component.
F, G: Dot Extent X (mm), Dot Extent Y (mm)
Set the dispense area (dot extend).
This parameter will be ignored if solder type adhesive is used.
H, I: Dot Amount X, Dot Amount Y
Set the number of dots to be dispensed in X and Y directions within the specified dispense area (Dot Extent).
This parameter will be ignored if solder type adhesive is used.
J: Angle Offset
Set the dispense angle. An angle between 0 and ±90° can be set in 5° steps.

5.3 IC components
5.3.1 Mini-mold transistors and SOT
Parameter examples for mini-mold transistors and SOT are given below. For parameters not explained here,
refer to the description in "5.2 Chip Components" of this chapter.
Mini-mold transistor parameters
Basic Shape Dispense
64524-N7-00
Basic parameters
A: Alignment Group
Set this parameter to “IC”.
B: Alignment Type
Set this parameter when creating data for solder type. Set to “Mini Tr/SOT” when the shapes of the opposing leads are
identical, and set to “P-Tr” when not identical.

Shape parameters
Set these parameters after specifying “Alignment Type”. If “Alignment Type” is undefined, the following parameters are
not displayed.
A, B: Body Size X, Body Size Y
Enter the correct dimensions (mm) including the leads, measured with a vernier caliper or micrometer.
D: Ruler Offset (Not used with this machine.)
E: Ruler Width (Not used with this machine.)
F, G: Lead Number NS
Enter the number of leads existing in the N and S directions.

J: Lead Width (Not used with this machine.)
Enter the correct lead width.
K: ReflectLL (Not used with this machine.)
Enter the projected length of leads which reflect light during recognition. Use the default setting in most
cases.
