④ Ball Pattern
Set a ball arrangement pattern here.
Combination of a base style and a ball pattern is used as a recognition pattern.
Choice
Remarks
Standard BGA
Peripheral BGA
Staggered std. BGA (More out) You can select this only when the pitch is from 2.00 mm to 3.00 mm.
Staggered per. BGA (More out)
You can select this only when the pitch is from 2.00 mm to 3.00 mm.
Staggered std. BGA (Fewer out)
You can select this only when the pitch is from 2.00 mm to 3.00 mm.
Staggered per. BGA (Fewer out)
You can select this only when the pitch is from 2.00 mm to 3.00 mm.
⑤ User pattern name
If you already created and registered a ball pattern(s) with the BGA editor, which is
described later, you can select a registered pattern here.
⑥ Peripheral Line
When you select “Peripheral BGA,” “Staggered per. BGA (More out)” or “Staggered per.
BGA (Fewer out) as a ball pattern, set the number of lines on which balls are located by
counting them from the outer periphery.
When you select any other type of ball pattern, “0” is displayed here, and this item is
disabled.
Example: When “4” is set as the Peripheral Line
⑦ Diameter check level
⑧ Variant check level
When “All balls-PWB” or “All balls-Ceramic” is selected as the “Contrast,” you can specify
whether to check the diameter/variant or not and the threshold value.
The input range of the level is from 1 to 100 %. The default value is 50 %.
When you specify the stricter check (by setting the smaller value), the rate of error becomes
higher.
- Diameter check level: The system measures the length and the width of each ball, and if
either of them exceeds (falls below) the set value, the system handles this as a recognition
error. It is recommended to specify 40 % or a bigger value.
- Variant check level: When the number of counted pixels per area of a ball that is
converted from the entered ball diameter is less than or greater than the set value, the
system handles this as a recognition error. It is recommended to specify 45 % or a bigger
value.

If either “1-(H/R)” or “1-(V/R)” is greater or less than the
set value (%) on the supposition that the entered
diameter value is “R,” the system will regard it as an
error.
