The VTV-9000 series includes a "BGA inspection tool" as a visual inspection tool for BGA (ball grid array) packages (rear surface). Because it is a special-purpose tool, inspections settings such as ball/pattern training can be easily performed, so inspections can be conducted without delay.
・The number of balls that can be trained is 100×100 = 10,000 (max.)
・A function that can easily perform ball training
・Ball cropping (automatic, manual)
・Ball models are integration models
・Masks can be put on ball models
・Each ball's score and contrast can be checked
・Ball position is automatically set
To set inspection items, simply select pre-prepared items.
Ball quality：Search score, contrast
Ball external form：Ball diameter, ball roundness
Ball position：X difference, Y difference, XY difference
The systems in the VTV-9000 series are not BGA-dedicated inspection systems. By adding various general-purpose inspection tools (package detection/inspection, blob inspection, DefFinder®: general-purpose visual inspections, etc), various combined inspections can be created.
ptimal straight lines from the edges of package boundaries are calculated, and points of intersection between them are used
to detect package positions. The detected package information makes various inspections possible.
Even for inspection targets like silicon chips that tend to vary in size, a mask for each chip is created along each rectangular edge.
Mask output will be precisely done for each target.

The VTV-9000 series uses a Lighting Controller that allows machine vision to turn the LED illumination ON/OFF and modulate the amount of light as required. By allowing illumination conditions to be changed, only the most appropriate illumination conditions can be used to suit inspection items, resulting in more reliable, precise inspections.
