Cameras improve full automation

Cameras improve full automation

Perpendicular camera for coaxial, diffuse lighting

Xyztec releases a range of 6.4M pixel vertical view camera systems with the addition of Coaxial (Light Field) and improved Diffused (Dark Field) illumination. These new systems increase automation capability and complement our existing high magnification image capture for:

  • Pattern recognition
  • Fiducial marks analysis
  • Wire detect
  • Failure mode analysis

High magnifications

The all new systems come with magnifications of 5X, 3X or Wide View (corresponding fields of view 1.5x1mm, 2.7×1.8mm and 15x11mm). This range covers high magnification test failure mode analysis and image capture through to fiducial mark analysis and wire detect enabling full automatic testing even when the position of the wires varies between sample batches.

1, 2 or 3  view camera systems can be mounted on a Sigma bond tester enabling the full range of magnifications. The systems are rigidly mounted with no moving parts (like mechanical zooms) to ensure the highest image positional accuracy. The new 6.4M Pixel camera chip and precision optics ensure the spatial resolution required for every application even when using digital zoom.

In this dark field example many wires are clearly made visible for easy camera programming of wire and bond positions. If the position of wires varies between samples our wire detect option automatically makes the required correction for each test.

Position of wires can vary

Failure mode analysis

Failure mode analysis is easy with our image capture options. This example of 250µm solder ball zone shear (total ball shear) at 50mm/s shows how 6 different failure modes are clearly visible.
