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.

Easy inspection setting

The VTV-9000 series comes with ingenious features for the training and management of “Ball/pattern” which is one of the most important items in the BGA functions.

  • 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
Easy inspection setting

To set inspection items, simply select pre-prepared items.

Inspection items

  • Ball quality
    >Search score, contrast
  • Ball external form
    >Ball diameter, ball roundness
  • Ball position
    >X difference, Y difference, XY difference

Many inspection items and combined inspections

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.

Inspections with two or more types of illumination conditions using illumination control

Not all inspections can be conducted with one set of illumination conditions. 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.
