8 12 0 RC1 504 RC2 The system failed to detect
any ball.
− This error occurs due to a wrong component
type.
− This error occurs also when a component is
not picked up.
− This error occurs also when a ball(s) is (are)
not displayed clearly due to its (their) stains
or oxidation.
− This error occurs also when the light does
not turn on.
− This error occurs also when contrast
between a ball and its background is low.
− This error occurs also when there are many
balls and many substances similar with a ball
on a component.
8 12 0 RC 508 RC2 The system failed to
position a component.
− The ball assignment setting is not correct.
− A wrong ball diameter is entered.
− This error occurs also when a ball(s) is (are)
not displayed clearly due to its (their) stains
or oxidation.
− This error occurs also when contrast
between a ball and its background is low.
− This error occurs when there are many
marks or other substances similar with a ball
on a component.
8 12 0 RC1 510 RC2 Time-out error (It takes four
seconds or more for the
system to recognize a
component, then the
system interrupts
recognition of the
component. This error
occurs at the VCS whose
version is 1.11AF or later.)
− The ball assignment setting is not correct.
− A wrong ball diameter is entered.
− This error occurs also when a ball(s) is (are)
not displayed clearly due to its (their) stains
or oxidation.
− This error occurs also when contrast
between a ball and its background is low.
− This error occurs when there are many
marks or other substances similar with a ball
on a component.
8 12 5 Raw Col The system failed to find
any ball.
− The ball pitch or diameter is not entered
correctly.
− This error occurs also when there is a
substance that reflects light easily such as a
mark around the perimeter of the package.
− The system has not performed calibration
(setting of the pixel rate).
8 12 6 Raw Col S ErLv
(ABS)
The ball area error occurs.
− This error occurs when a ball is chipped.
− This error occurs also when a ball(s) is (are)
displayed clearly due to its (their) stains or
oxidation.
This error occurs also when a ball is deformed
entirely.
8 12 7 Raw Col D ErLv
(ABS)
The ball diameter error
occurs.
− This error occurs when a ball is chipped.
− This error occurs also when a ball(s) is (are)
displayed clearly due to its (their) stains or
oxidation.
− This error occurs also when a ball is
deformed entirely.
8 16 Xd Yd The correction amount
between divided views is
abnormal.
− The distance between views is not set
correctly.
− The view angle is not set correctly.
Pitch: Detected ball pitch (mm)
Row: Row number of a ball at which the system detected an error
(0, 1, 2 … viewed from the top of the screen)
Col: Column number of a ball at which the system detected an error
(0, 1, 2 … viewed from the left side of the screen)
S: Area of a ball at which the system detected an error (mm2)
D: Diameter of a ball at which the system detected an error (mm)
ErLv: Error ratio of a ball at which the system detected an error (%)
(ABS): Difference between the average value of all ball dimensions and those already set
(%)
Rc1: Main error code internally processed with VCS
Rc2: Sub error code internally processed with VCS
“Rc1” and “Rc2” show the internal recognition block or internal evaluation parameter used with
VCS. These do not show the direct (physical) cause of an error, but are necessary for
analyzing the error. Let us know these numbers when you contact us.

Example
RES 1 1 PBGA_ALL 0 8 7 0 2 0.6 65.0
Description of the error: The diameter of a ball located at the
Row 0 and Column 2 of a BGA
component whose ID is “0” is abnormal
by 65 %.
(When the system detected the ball diameter as 0.99 mm
although the value already set is 0.6 mm.)
Dir: Direction of a ball at which the system detected an error
(0: upper or lower direction 1: left or right direction)
L: Brightness of a ball at which the system detected an error (0 to 255)
Lth: Judgment value of the ball brightness (0 to 255)
En: Ball number at which the system detected an error with its ball existence check
Dia: Diameter of a ball at which the system detected an error first with its ball existence check
(Pixel).
V: Luminance of a ball at which the system detected an error first with its ball existence
check.
Vth: Judgment value of the ball luminance used for ball existence check
Xd: Horizontal correction amount for an error
Yd: Vertical correction amount for an error
The values “V” and “Vth” are used to judge the average luminance value (0 to 255) in some
cases, or used to judge the total luminance value in other cases.
If either “V” or “Vth” exceeds 255, these values are used to judge the total luminance value.

the component perimeter is not clear.
