i-LITE

i-LITE is the result of the optical and mechanical modeling carried out for a wide range of PCB finishes and components used by our global customers. This unprecedented study resulted in the
Vi TECHNOLOGY team designing an innovative acquisition system, combining multi-angle incidence and multi-color high-reliability LED lighting with a high-resolution camera associated with a top quality Telecentric lens. Spectral analysis was performed to determine the optimum wavelength of the LEDs used in SMT inspection. The resulting choice (Red, Green and Blue) optimizes inspection whilst also providing a colored image on the operator's display screen.

 

Improvements to image quality are clearly visible, and the benefits go far beyond what the human eye can perceive as i-LITE drastically reduces the defect false call rate, thereby increasing the AOI's First Pass Yield (FPY).
Defect coverage, image acquisition speed and ease-of-use have been significantly improved. In customer tests, reductions of up to 55% have been recorded on already low false call rates. Enhanced lighting uniformity in the camera's field of view not only requires fewer acquisition zones, but also reduces the number of library models and links used for inspection. Customer tests showed that inspection time was decreased by up to 15%.
All these advantages have a direct impact on the AOI's return on investment.

With  i-LITE, Vi TECHNOLOGY raises the bar of inspection reliability higher than ever before. Designed to offer better program stability while reducing tuning time with minimal library adjustment, i-LITE easily fits into Vi TECHNOLOGY's user-oriented approach.
